The Fabulous 00s: USCL Week 8

October 20, 2009

Scorpions Sting Again; ICC Kibitzers Hopelessly Confused

Well, the Scorpions did it again!  They squeaked by the Chicago Blaze 2.5 – 1.5

Let’s see a very important ending on board 3 where Mehmed Pasalic (CHI) was battling Danny Rensch. A very dramatic battle with several key, instructive moments.

Pasalic (CHI) – Rensch (ARZ)  Sicilian Najdorf

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.f4 e5 7.Nf3 Nbd7 8.Bd3 b5 9.0-0 Bb7 10.Qe2 Be7 11.Kh1 g6?! I don’t understand this move. I would just cackle. I can do …g6 later, usually as a reaction to white’s probe Nf3-h4 move.

12.fxe5 dxe5 13.Bh6 Ng4 14.Bd2 Nc5 15.Rad1?! After something like 15. h3 h5 16. a3, black’s knight is just hanging in limbo on g4 and white is better.

15…Nxd3 16.cxd3 b4 17.Nb1 h5 18.Be1 Qb6 19.Bf2 Nxf2+ 20.Rxf2 Qe6 21.Nbd2 0-0 22.Nc4 f6 Black’s kingside pawns look funny but white doesn’t have the right pieces on the board to exploit it.

23.Qe3 Kg7 24.Rc2 Rfc8 25.h3 a5 26.b3 a4 27.Qe1 Rd8 28.Re2 Ba6 29.Rc2 Bxc4 More foxy is 29…axb3 30. axb3 Rac8 and black can decide when or if to play Bxc4.

30.dxc4 axb3 31.axb3 Rxd1 32.Qxd1 f5 33.Re2 Rd8 34.Qe1 Bf6? 34…f4 kept the balance.

35.Qxb4 Rd3 36.Qb8! This is strong and black might have underestimated it.

36…fxe4 37.Qb7+ Kh6 38.Qxe4

White has control

White has control

After an up and down game, white is starting to assert himself.   It is starting to get really interesting, and this is when I started watching. It didn’t look good.

This is a good moment to pause due to a tactical nuance.

Here ICC kibitzers initially were calling for black to take on b3:  38…Rxb3.  Another kibitzer pointed out that this was not playable due to “38…Rxb3 39. Nd4!” so we thought it was unplayable. But go a little deeper!    39. Nd4 Rxh3+!! (a fantastic resource!) 40. Kg1 (40. gxh3? Qxh3+ and black is not worse at all) 40…Qb6! and black is only a little worse!

38…Qd6?

Both sides were running low on time.  Here white missed two clean wins.

The easiest, as pointed out by IM D. Fernandez, was 39. Rd2!!  Rxd2 40. Qe3+ Kg7 41. Nxd2 and white is completely winning, maintaining the e4 blockade.

The second choice, and very popular in ICC kibitzing (but inferior to Fernandez’s move but it’s harder to work out), was the more complicated 39. b4. After 39…Rd1+ 40. Re1 Rxe1+ 41. Qxe1 e4 it’s time for another interesting quiz.   What’s best here?  Answer to be posted later.

White to Play. Quiz Time (analysis)

White to Play. Quiz Time (analysis)

Position after 41….e4; White to play and win (analysis).  Can you solve it?

39.Nxe5?! White bypasses both of those wins, but as we shall see, this should have been winning too.

39…Bxe5 40.Qxe5 Qxe5 41.Rxe5 Rxb3

Yermolinsky Sets Us Straight

Most ICC kibitzers felt this was totally drawn.  Only GM Yermolinsky was wise enough to enlighten us – see comment to white’s 43rd move.

42.h4! The correct first step to fix the g6 pawn.

42…Rc3

Moment of Truth

Moment of Truth

43.Rc5??

Only GM Yermolinsky recognized this as a blunder.  He laid out a winning plan that is foolproof and brilliant in its simplicity.  In hindsight obvious, but he is the only one that saw it among the gawking multitudes.  Put pawn on c5, he said, and prepare then put pawn on g3, and Rook on g5 holding everything, and move king to queenside.  Indeed, that pins black’s king to g6, and black is helpless against the white king shepherding the c-pawn.  A fantastic, simple in hindsight, and very aesthetic plan!  Black is completely powerless to stop its realization.

Clearly Pasalic missed it, but so did most of the ICC kibitzers.

43…Rc2 44.Rc7 Rd2 45.Kh2 Rd4! By bothering white’s kingside pawns, the black rook “latches on” and prevents any further progress. The Scorpions win the match by the narrow 2.5 – 1.5 margin!

46.g3 Rd3 47.c5 Rd2+ 48.Kg1 Rc2 49.Rc8 Kg7 50.Rc6 Kf7 51.Kf1 Kg7 52.Rc8 Kf6 53.c6 Kf5 54.c7 Kg4 55.Rg8 Rxc7 56.Rxg6+ Kf3 57.Kg1 Rc2 58.Rb6 Kxg3 59.Rb3+ Kxh4 60.Rb4+ Kg3 61.Rb3+ Kg4 62.Rb4+ Kg3 63.Rb3+ Kg4 64.Rb4+ Kg3 Game drawn by repetition 1/2-1/2

Wow!  A great fighting, titantic battle in the best USCL tradition!

Last year, I, too, held a draw in a bad game vs Pasalic to win a CHI-ARZ match.  Chicago must be getting tired of us!

What Else is New?

I’m involved in a fierce smutty movie debate with a female chess player on Facebook. Fear not, gentle reader — our debate is not smutty – only the movie is.

The Fabulous 00s: USCL Week 7 Opening of the Week (OOTW)

October 19, 2009

Let’s explore an interesting junior battle.

Gerald Larson (TEN) – Trevor Magness (CHI)  USCL Week 7

Ruy Lopez Exchange

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.0-0 Bg4 6.h3 (?!)

Let’s try NOT doing h3 yet (this committal move gives black a ready-made lever on the kingside).  I’m going to recommend here 6. d3!? Qf6 7. Nbd2 O-O-O 8. a4!? awaiting events.  For example, 8. a4 g5 9. h3 Bh5 10. Qe2! Kb8 11. g4! Bg6 12. Nc4! and white has an edge.  Delaying h2-h3 looks foxier. It also probably has the advantage of taking black out of the well-known channels.

6…h5! Of course! Known to be bad for white now is 7. hxg4 hxg4.

I enjoy junior games.  There will always be the sharpest twist on the most innocuous starting positions.  No theoretical verdict has been reached on this line.  Let’s see what happened…

7.d3 Qf6 8.Nbd2 Ne7 9.Re1 Ng6 White is fairly tied up now due to the pressure on f3.  His next move alters the structure but he could also eat on g4 at this moment.

Key Moment

Key Moment

10.d4

After the only optically risky 10. hxg4!? hxg4 11. Nh2? Bc5! black had a big edge and won in Fressinet-Kazhgaleyev, Paris 1996.  Correct is 11. g3! and white holds after some adventure: 11. g3! Bc5 12. Nb3! Bb6 (Looks terrible for white, doesn’t it?  But… white escapes!) 13. Bg5 Qxf3 14. Qxf3 gxf3 15. Nd2 f6 16. Be3 Ba5! 17. c3 O-O-O 18. Rad1!! Rxd3 19. Nc4! and draws!

10…Nf4 11.dxe5

I guess it’s too much to ask for the nice trap 11. hxg4 hxg4 12. Nh2 Nxg2!! winning, as has occurred in a bunch of games.

11…Qg6! 12.Nh4! The only way to hold the balance!  Still, black can and should have posed problems before white reaches safety.

12…Bxd1 13.Nxg6 Nxg6 14.Rxd1 0-0-0 15.e6 fxe6 The foxy 15…f6!? is perfectly possible but it’s still equal.  15…f6!? has the virtue of keeping things relatively speaking more complicated.

16.Re1 Bb4?! 16…Ne5! sets practical problems and black has the easier time of it.  The text forces white to make a useful move.  Anyway, we’re far afield of the opening now — black’s setup passed the theoretical test!

17.c3 Bc5 18.Nb3 Bb6 19.Be3 Rd3 20.Bxb6 cxb6 21.Rad1 Rhd8 22.Rxd3 Rxd3 23.g3 Kd7 24.Kf1 Ke7 25.Ke2 Rd8 26.Rd1 Rxd1 27.Kxd1 Ne5 28.Nc1 Nf7 29.h4 Kd6 30.Ke2 c5 31.Nd3 g5 32.hxg5 Nxg5 33.f3 Nh7 34.e5+ Kd5 35.Ke3 b5 36.Kf4 a5 37.Nf2 a4 38.Ne4 Kc4 39.Ke3 b4 40.Nd6+ Kd5 41.f4 b6 42.c4+ Kc6 43.Ke4 Kd7 44.Kd3 Nf8 45.Ne4 Ke7 46.Nf6 h4 47.gxh4 Ng6 48.h5 Nxf4+ 49.Ke4 Ne2 50.h6 Kf7 51.Nd7 Nc3+ 52.Kd3 Nxa2 53.Nxb6 a3 54.bxa3 bxa3 55.Nd7 Nb4+ 56.Kc3 a2 57.Kb2 Kg6 58.Nxc5 Kxh6 59.Nxe6 Nd3+ 60.Kxa2 Nxe5 61.c5 Kg6 62.Kb3 Kf6 63.Nd4 Ke7 64.Ka4 Kd7 65.Kb5 Kc7 66.Ne6+ Kb7 67.Nf4 Kc7 Game drawn by mutual agreement 1/2-1/2

The Fabulous 00s: A Titantic Week 7 USCL Matchup

October 15, 2009

Scorpions-Mechanics: Not for the Faint of Heart

Wow, I am still freaking out a day later.  The Arizona Scorpions and the SF Mechanics played a titantic match on 10/14/09 that will go down in USCL annals as one of the most topsy-turvy matches ever.

I was really pleased to see David Adelberg play the Kan on board 4 for Arizona, consistent with my match preview! Although he got fatigued and eventually lost his way, I am very happy with how well the fearsome Kan did in the opening.

Here is Board 2’s madness.

IM John Donaldson (SF) – IM Dionisio Aldama (ARZ)

1.Nf3 Nf6 2.c4 g6 3.g3 Bg7 4.Bg2 0-0 5.0-0 d6 6.d4 Nc6 7.Nc3 a6 8.d5 Na5 9.b3 c5 10.dxc6 Nxc6 11.Bb2 Bd7 12.Qc1 Rc8 13.Nd5 Nxd5 14.Bxg7 Kxg7 15.cxd5 Ne5 16.Qb2 f6 17.Nd4 Qb6 18.Qd2 a5 19.f4 Kg8 20.e3 Nf7 21.Rac1 Rc5?

21…Nh6! and black is fine.

22.Ne6! Rxc1 23.Rxc1 Rc8 24.Rxc8+ Bxc8 25.Qd4 Qxd4 26.Nxd4 Bd7 26…Nh6! to hold white to a small edge.

27.Kf2 Kf8 28.Ke2 Ke8 29.Kd3

Black has an awful position.  His next few moves make it worse.

29…Kd8 30.Ne6+ Kc8 31.Nf8! This should have been the winning move.  Robby Adamson and I were not sanguine about black’s chances.  GM Ramirez also wondered what the hell black was doing.  We were like hens in a henhouse virtually running around in our little cyber barn.

31…Kd8

don000

Snap on h7?  Snap on d7?  King move?

32.Ne6+? What’s this?   The horse was powerful on f8. There is no way John is going to repeat, I told myself (and others) – he’s just gaining time on the clock.  But then:

32…Kc8 33.Nf8 Kd8 34.Ne6+? Game drawn by repetition 1/2-1/2

Go back to the diagrammed position.  You have very good tactical and positional endgame insight if you can spot the lines which gives white a big plus, which I have posted in the comments.  The solutions (multiple!) are instructive.

Take on h7?  Take on d7?  A king move?  Very tempting possibilities, and hard to work out in the USCL time limit!

The other matchups were equally nuts and very tense for players and spectators alike.  It was only decided in the wee hours when Arizona’s Barcenilla won Q vs R against San Francisco’s Vinay Bhat. 

The Fabulous 00s: USCL Week 6 Opening of the Week (OOTW)

October 8, 2009

The Inscrutable Chinese Dragon

I guess we could say it’s a gambit of structure (backward pawn on d6 after black moves e7-e5) for activity.  It’s not to my taste at all, but so far this USCL season Shabalov has tried it versus Kudrin and Kiewra just tried it versus Bick.  And black so far stands at 1-1.

Let’s see these games.

John Bick (TEN) – Keaton Kiewra (DAL)  Chinese Dragon

1. e4 c5 2. Nf3 d6 3. d4 Nf6 4. Nc3 cxd4 5. Nxd4 g6 6. Be3 Bg7 7. f3 O-O 8. Qd2 Nc6 9. Bc4 Bd7 10. O-O-O Rb8 The characteristic move of the Chinese Dragon.  In 1974-5, Paul Whitehead (upholding black) and Jay Whitehead (upholding white) were debating the merits of the other mainlines in countless blitz games at the San Francisco Mechanics Chess Club with 10…Rc8 and 10….Qa5 and ….Rfc8.

Chinese, anyone?

Chinese, anyone?

In defense of the Chinese, I think it makes more sense than …a7-a6 which Magnus Carlsen tried a few times (notably getting crushed by Topalov).  In case you were wondering how it got its name, Gallagher writes about its dubious origins in the 2002 NIC magazine.  Some journalist just happened to be in China…

11. Bb3 Na5

When the Chinese Dragon first got on the radar in 2002, Chris Ward tried 11… Ne5.  An unimpressed Joe Gallagher wrote in NIC magazine “I do not predict a bright and glittering future for the Chinese Dragon.”  Nevertheless, that game Gallagher-Ward British Ch. 2002 ended in a draw after  12. f4 (12. Bh6 Bxh6 13.
Qxh6 b5 14. Nd5 Nxd5 15. exd5 a5 16. Nc6 Bxc6 17. dxc6 e6 18. h4 a4 is an unsound piece sac for white — 19. h5 Qf6 20. hxg6 Qxg6 21. Qxg6+ hxg6 22. Bxe6 fxe6 23. Rxd6 Kf7 and black is better.

Also possible is 12. h4 b5 13. h5 Nc4 14. Bxc4 bxc4 15. h6 Bh8 16. Nf5 Bxf5! (not 16…gxf5?? 17. Bb6! winning)  17. exf5 Qa5 18. fxg6 Ne4 19. fxe4 Qxa2! (the tempting at first glance 19…Rxb2? 20. g7! wins for white) 20. Nxa2 Bxb2+ 21. Kb1 Bc3+ with a humorous draw!

12… Neg4 13. Bg1 b5 14. h3 b4 15. hxg4 bxc3 16. Qxc3 Rc8 17. Qg3 Bxg4 18. Re1 Qa5 19. c3 e5 20.
fxe5 dxe5 21. Nf3 Rxc3+!  Not very hard to see but nevertheless a pleasing drawing combination from Chris Ward, Dragon aficionado.

22. bxc3 Qxc3+ 23. Kb1 Rc8 24. Bxa7 Qd3+ 25. Kb2 Qc3+ 26. Kb1 Qd3+ 27. Kb2 Qc3+ {And drawn, Gallagher-Ward British CH 2002.})

Conclusion:  11…Ne5 needs re-examination because the way this game goes isn’t very pleasant for black.

12. Bh6 Bxh6

It’s not risky per se to have the white queen drawn out to h6, but it can always go back and black has not gained time. 12… b5 13. Nd5 Nxb3+ 14. Nxb3 Bxh6 15. Qxh6 doesn’t look too different from the game and black has problems.

13. Qxh6 b5 The weird gambit 13… e5 14. Nde2 b5? (marginally better 14… Nxb3+ {Kurnosov-Pavlovic, Hastings 2009 but black faced the usual difficulties and white won} was played in Zambrana-Yuan, Sao Paulo 2008.  White then played the lemon 15. h4? and lost but he should have taken on d6 with an edge.

14. Nd5! Of course!   This is a key moment.

Decisions, Decisions

Decisions, Decisions

14…e6?! As Shabalov played against Kudrin earlier in the USCL year, but this position is just suffering for black.  Die-hard Chinese-ites will play 14….e5 here and claim near-equality.  And maybe they are right – it’s hard to break down black’s game.  Afterthought: the move 14…e5 15. Nf5!? is interesting here and worth careful examination; white might keep a small plus. I don’t know how much 15. Nf5!? has been analyzed elsewhere; better ask Golubev. :)

From black’s point of view, it’s worth also looking at 14…Nxb3+.  This is actually transposing, usually, to 14…e5.  Then, 15. Nxb3 e5 is best met with 16. Nxf6+ Qxf6 17. h4!? or the simple 17. Kb1 and white has a small edge.  Instead,  Robson played 16. h4?! against Papp in Spice(B) 2009, and Papp gained equality after 16…Nxd5 17. Rxd5 Rb6.  Papp lost later after weakening himself unnecessarily with …g6-g5? on the solid kingside and falling prey to a tactic.  Conclusion:  this is the last spot for black to avoid getting  a lasting disadvantage with either 14….e5 or 14…Nxb3 (these two often converge).  We’ll have to ask Golubev what he thinks.

15. Nxf6 Qxf6 16. h4 Qg7 17. Qg5! Excellent, as Kudrin played against Shabalov.  Black is under pressure.   This move pinpoints black’s positional deficiencies and is exactly why I don’t like the 14…e6?! line for black.

17…Nc4

It’s hard to recommend anything.  What do the waiting 17…Rb7 or 17…Rfe8 accomplish?  Shabalov played 17…Qe5 18. Ne2 Bc6 19. Rd2 Rfd8 20. Rhd1 Nb7 (clearly black is suffering) 21. Nf4 a5 22. a3 Re8 and here Kudrin could have capped his fine play with the powerful 23 .Qxe5! dxe5 24. Nd3 f6 (forced) 25. g4! and white will break up black’s king side structure with a winning edge. This nice sequence is hard to see in the rapid USCL time control.  Unfortunately, Kudrin went wrong with 23. Nd3? Qxg5 24. hxg5 Kg7 25. e5 Red8 26. exd6 Rxd6 27. Ne5 (white is still better) 27…Rxd2 28. Rxd2 Be8 and now he missed another shot to keep the edge, 29. Ng4! stopping h6.

After Kudrin’s second lemon, 29. Ba2? h6! black was fine and went on to turn the tables in a key match victory, Kudrin (PHI) – Shabalov (TEN) USCL 2009.

18. Bxc4 bxc4 19. h5?! 19. Qe7! looks good.

19…c3?! Leaving the pawn on c4 is stronger, for example 19…Rb7 preparing to double on the b-file.

20. b3 Now the c3 pawn is a goner.

20…Rb4  21. h6 21. Qe3 also kept a big edge for white.

21…Qh8 22. Ne2 Rb6 23. Ng3? The easiest win is 23. e5! d5 24. Nxc3.

23… Rb5? 23…Bb5 was the toughest.  Anyway, we’re far afield from the opening now, so we will show the rest rapidly.

24. Qe7 Qe5 25. Qxd7 Ra5 26. a4 Easiest was 26. Kb1! Qxg3 27. Qxd6 since the game motif 27… Qxg2 is met by 28. Qd4! e5 29. Qxc3 and wins.

26…Qxg3 27. Qxd6 Qxg2 28. Qd4 Qg5+ 29. Kb1 Qe5 30. Ka2  Qxd4 31. Rxd4 f5 32. Rc4 fxe4 33. fxe4 Rh5 34. Rxh5 gxh5 35. Rxc3 h4 36. b4 Rf4 37. Re3 Kf7 38. Kb3 Kg6 39. b5 Kxh6 40. a5 Rf1 41. Kc4 Kg5 42. Rb3 Rf8 43. b6 axb6 44. axb6 Kg4 45. b7 Rb8 46. Kc5 h3 47. Kc6 h2 48. Rb1 Rg8 49. Kc7 Rg7+ 50. Kb6 Rg8 51. Ka7 Kf3 52. b8=Q Rxb8 53. Kxb8 h5 54. c4 Kxe4 55. Rd1! 1-0

Sveshnikov Postscript: Further Weirdness

I’m not understanding why Herman in Herman (NY) – Uesugi (BAL) USCL Week 6 diverged from Martinez-Uesugi USCL 2009 Week 4 in his Sveshnikov matchup in Week 6. After all, maybe Uesugi had not read yet the refutation!

The Fabulous 70s: The National Chess League

October 6, 2009

Before the current-day US Chess League, we had the National Chess League played with telephones!  (pre-Web).  Runners would relay the moves with lingo like “Baker echo 7″ (Be7).  Often times, a move was mis-relayed causing the game to back up and restart.  Games could take hours with the relay delays, although nominally the time control was G/1 hour with no increment.

Here are 3 amusing contests from the 1979 season, including one from the playoffs.

IM Dumitru Ghizdavu (CLE) – Mark Ginsburg (DC)  Sicilian Scheveningen, 4/22/79

I would hazard a guess my opponent hies from Romania.

1. e4 c5 2. Nf3 d6 3. d4 Nf6 4. Nc3 cxd4 5. Nxd4 e6 6. Be3 a6 7. f4 b5 8. Qf3 Bb7 9. Bd3 Nbd7 10. g4 b4 A wild line very popular at the time.

11. Nce2 e5 12. Nb3 h5!?

13. g5 Ng4 14. f5 Nxe3 15. Qxe3 a5 16. O-O-O a4 17. Nd2 d5!? 18. exd5 Bc5 19. Qg3 Bxd5 20. Be4 Bxa2 21. Bc6

21…Rc8? I totally missed 21… O-O! 22. Ne4? (22. f6 Rc8  unclear) 22… Qb6 23. Bxd7 Be3+ 24. Nd2 Rfd8! and black wins.

22. Bxa4 O-O 23. Ne4 Qb6 24. Rxd7 Be3+ 25. Kd1 Rfd8 Still, I generate play against white’s floating king.

26. Ke1 Rxd7 27. Nf6+ Kh8 28. Nxd7 Qa7 29. b3 Rxc2 30. Qf3 Bxb3! The craziness continues.  Quite a game!

31. Qxh5+ Kg8 32. g6

Key Moment Deux

Key Moment Deux

32…Bh6? I don’t think I had a lot of time left.

This second blunder is fatal.  I could have survived with  the wild sac (consistent with the rest of the game) 32… Rxe2+! 33. Kxe2 (33. Qxe2 Bxa4 34. gxf7+ Kxf7 35. Nxe5+ Kg8 36. Qc4+ Kh7 37. Qxb4 Bc2 38. Qc3 Bxf5) 33… Bc4+ 34. Kf3 Bd5+ 35. Kg4 Bh6)

33. Bxb3 Qa1+ 34. Kf2 Qd4+ 35. Kg3 Bf4+ 36. Kh3 Qd3+

I should have at least tried 36… Qe3+ hoping for 37. Ng3??  Rxh2+! 38. Rxh2 Qxg3 mate but it is hard to believe Ghizdavu would fall into that one.

37. Kh4 Bg5+ 38. Qxg5 Qe4+ 39. Qg4 Qxh1 40. gxf7+  1-0

In an amusing postscript, Ghizdavu recently popped up on the Arizona Scorpions USCL blog (see Comments section) announcing he’s moved to …. surprise ….. Surprise, AZ!   I would have to guess that DC won this Cleveland match but I didn’t record the individual board results.

M. Ginsburg (DC) – Julius Loftsson (LA)  Sicilian Taimanov 3/18/79

1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nc6 5. Nb5 d6 6. c4 Nf6 7. N5c3

Unusual and tried by Ljubojevic sporadically.

15. b4 Qb8 16. Qb3 Bc6 17. f4 Ng6 18. h4?!
A very junior move. All my pawn advances come to naught and black is fine.

Rfd8 19. h5 Nf8 20. a4?! a5! I have no idea why I played my 20th.

21. bxa5 bxa5 22. Bf3 N8d7

23. e5?? Utter confusion on my part. A really ugly and mistimed advance that should have just handed black the game.

23… dxe5 24. fxe5 Bxf3 25. Qxb8 Nxb8 26. Nxf3 Nxh5 27. Bh2 Rxc4 I shed some pawns with no compensation.  Can you envision white winning?  No?  But look what happens.

28. Ne4 Rxc1 29. Rxc1 g6?!

Simplest was 29… Na6 stopping any play; e.g.  30. Nd6 g6 and black wins.

30. Rc7 Nd7 31. Nd4 Nc5?

Black had the nice 31… Bc5! 32. Nxc5 Nxc5 33. Rxc5 Rxd4 34. Rxa5 g5 and he should win.

32. Nd6 Bxd6? Another mistake and this one is serious enough to turn the game completely around.  32… Bg5! 33. Rxc5 Be3+ 34. Kf1 Bxd4 35. Rxa5 Ng7 36. Ke2 Nf5 37. Ra6 Rb8 and black is better.  He was probably in time trouble.

33. exd6 Ne4 Black is also losing after 33… Na6 34. Nc6 Rf8 35. d7 Nxc7 36. Bxc7 Nf6 37. Ne7+ Kg7 38. d8=Q Rxd8 39. Bxd8

34. d7 1-0

I think that DC won this match as well against LA.

So we got into the playoffs and here is a game from the Semi-Finals, DC versus the strong Berkeley Squad.  This time around I did record individual board results (see below).

IM Julio Kaplan (Berkeley Riots) – M. Ginsburg (DC Plumbers)  King’s Indian, 4 Pawns Attack, Benko-Gambit-esque

If you are wondering about the Plumbers name, look up the White House Plumbers and the notorious Watergate Scandal that occurred during President Nixon’s reign of terror.
1. d4 Nf6 2. c4 c5 3. d5 g6 4. Nc3 d6 5. e4 Bg7 6. f4 O-O 7. Nf3 b5

Believe it or not, at the time I notated this as “!”  It works out well in the game but white was very compliant, opening lines up for black.

8. cxb5 a6 9. e5?! Former World Junior Champ Kaplan is aggressive, but I don’t like this at all.

9…dxe5 10. fxe5 Ng4 11. Bf4 Nd7 12. bxa6 Ndxe5 Black has a great game now.

Big Plus Already!  What can go wrong?

Big Plus Already! What can go wrong?

13. Nxe5 Nxe5 14. Qd2 c4! I’m playing well!  These motifs are obvious to Benko players but I was totally on my own.

15. Bxe5 Bxe5 16. Bxc4 Qc7 17. Be2 Bxa6 18. Bxa6 Rxa6 19. O-O Bxh2+ 20. Kh1 Be5 21. Rf3 Rf6 22. Rxf6 Bxf6 23. Ne4 Bg7 24. Re1 Rd8 25. Nc3 Qc4 26. Re3? A huge lemon, of course, but white had a bad game.

Qf1+ 27. Kh2 Bh6 As simple as that, black is winning.  But remember a kid is playing an ending, and accidents can happen to kids.

Yay.  I win?

Yay. I win?

28. Re1 Bxd2 29. Rxf1 Bxc3 30. bxc3 Rxd5 31. Rf2 e5 32. a4 Rc5 33. Rc2 Rc4 34. Ra2 Rxc3
35. a5 Rc7 36. a6 Ra7 37. Kg3 f6 38. Kf3 Kf7 39. Ke4 Ke6 40. g4

Is it possible not to win?

Is it possible not to win?

It’s hard to conceive of black not winning this position.

40…f5+

Easier is 40… h5 41. gxh5 gxh5 42. Kd3 Kd5 43. Ra5+ Kc6 44. Ke4 Kb6 and after dealing with the white pawn there are no obstacles for black.

41. gxf5+ gxf5+ 42. Kf3 h5 43. Ra1 Kf6 44. Ra2 h4? Completely off my radar was the simple 44… f4! 45. Ke4 h4 46. Ra5 h3 47. Rxe5 Rh7 48. Rf5+ Kg6 and black wins, since the h1-a8 diagonal skewer is decisive.

45. Ra1 Ra8?? Did I really do that?  What a nonsensical blunder. Well by now it was obvious I was incompetent so I doubt another stronger move would have “won” for me.

46. a7 h3 47. Kg3 e4 48. Kxh3 Kg5 49. Ra5 Kf4 50. Kg2 Kg4 51. Ra4 f4 52. Rxe4 Rxa7 53. Re8 Ra2+ 54. Kg1 Kf3 55. Rf8 Ra5 56. Rf7 Ra1+ 57. Kh2 Rf1 58. Ra7 Re1 59. Rf7 Re5 60. Kg1 Rg5+
61. Kf1 1/2-1/2
Quelle desastre!

Here are the board results:

DC                     –       Berkeley

Mark Diesen   0   John Grefe

future IM Steve Odendahl 0  Paul Whitehead (I commented that Odendahl stood much better and went nuts)

Larry Kaufman  1  Jay Whitehead

Richard Delaune 1/2  Cornelius

John Meyer 0  DeFirmian (I noted that John lost on time with a queen versus a rook!)

So we lost this Semi-Final match 2 to 4.

Military History, Anyone?

Is anyone awake at the Pentagon?

This Afghanistan story of heavy American casualties from cnn.com:

“The battle Saturday in which eight U.S. troops were killed was so fierce that, at one point, U.S. forces had to fall back as attackers breached the perimeter of their base, a U.S. military official with knowledge of the latest intelligence reports on the incident said.

Forward Operating Base Keating, seen in 2007, is surrounded by tall ridge lines.

Forward Operating Base Keating, seen in 2007, is surrounded by tall ridge lines.

The new revelations about the battle that engulfed Forward Operating Base Keating in Kamdesh District are a further indication of how pinned down and outmanned the troops were at the remote outpost. The base, in an eastern Afghanistan valley, was surrounded by ridge lines where the insurgents were able to fire down at U.S. and Afghan troops.

The facility had been scheduled to be closed within days, CNN has learned. The closing is part of a wider effort by the top commander in Afghanistan, Gen. Stanley McChrystal, to cede remote outposts and consolidate troops in more populated areas to better protect Afghan civilians.”

It’s hard to believe that we haven’t learned our lesson from famous failures in the past to hold remote outposts.  A classic siege, Dien Bien Phu, saw the French try to hold a similar, ridiculously located, forward base to great cost.  Read “Hell in a Very Small Place” by Bernard Fall for that incredible account. I attach more information about this amazing book at the bottom of this article.  Even the USA’s own President, LBJ, when fortifying the ludicrous outpost Khe Sanh in Vietnam said “I don’t want another damn DIN BIN FOO.”

Why did we try to keep and hold a new DIN BIN FOO in Afghanistan?  A failed strategy cannot work if you fast-forward it in time.  This is the theme of the classic book of repetitious military failure throughout the ages, “The March of Folly” by Barbara Tuchman.  Hello, Pentagon?  Once agin:  we don’t want another damn DIN BIN FOO.  Forward, remote operating bases are sitting ducks.

If we are going to be in a far-away country trying our hand at “World Police” (that didn’t work too well for the British in the early 20th century), we might as well learn from prior military disasters.

More on “Hell in a Very Small Place”

From Amazon,

“he siege of Dien Bien Phu, in which a guerrilla force of Viet Minh destroyed a technologically superior French colonial army, must rank with Waterloo, Gettysburg, Midway, Stalingrad, and Tet as one of the decisive battles in military history. Not only did Dien Bien Phu put an end to French imperial efforts in Indo-china, but it also convinced the Viet Minh, when they came to power in Communist North Vietnam, that similar tactics would prevail in their war with the United States. As an American army officer told Bernard Fall during the Vietnam War: ”What we’re doing here basically is, we’re exorcising Dien Bien Phu.”Bernard Fall in this monumental work has written an exhaustive, revelatory, and vivid account of the battle, leading the reader from the conference rooms of the U.S. State Department to the French Foreign Office to the front lines of Indo-China and the strategy sessions led by General Giap and Ho Chi Minh. Among the many historical curiosities here disclosed is evidence that then-Secretary of State John Foster Dulles offered atomic bombs to the beleaguered French, and that then-Senator Lyndon Johnson played a key role in defeating a proposal to aid the French with critical air support. Without U. S. aid, the fortress at Dien Bien Phu fell on the very day that the cease-fire conference opened in Geneva.Based on hitherto unavailable documentation from the French Defense Ministry, and replete with detailed maps of the many assaults, Hell in a Very Small Place is a first-rate military history. But even more powerful is the political wisdom it imparts about a war that was not only the beginning of the end of the French colonial empire but a rehearsal for American involvement in Vietnam.”

Tragically, the author Bernard Fall died while embedded with Marines in South Vietnam in 1967.



The Fabulous 00s: USCL Week 5 OOTW

October 1, 2009

USCL Week 5 Opening of the Week

The Foxy Rauser Deviation, as practiced by IM Albert Kapengut many times and also me at Lone Pine 1980.  Albert used it most recently on the NJKO USCL team to defeat IM M. Pasalic of the Chicago Blaze in USCL Week 5 action.  Let’s see the “historical game” first to gain perspective.  Interestingly, I was playing a typically well-prepared representative of the former Soviet Union and against this type of player, “eccentric” early deviations are not a surprise!

Mark Ginsburg – IM Vitaly Zaltsman Lone Pine 1980.  Sicilian Rauser, Foxy Deviation

In this tournament, held shortly before my 21st birthday, I was mired in disappointment and blunders with only a nice win over John Grefe to my credit in a “Lenderman-special” Neanderthal Ruy Lopez Cordel defense with an early Qd8-f6.  When I say “Lenderman-special” I mean that it has been tried by Lenderman and also it’s very bad. :)

It’s very funny to think that my “eccentric” Sicilian gambit in the Zaltsman game would resurface in a USCL game featuring veteran IM Albert Kapengut in his win over Chicago IM M. Pasalic. No wonder Zaltsman blitzed off his first 15 moves – it must be in Soviet academies!

1. Nf3 c5 2. e4 Nc6 3. Nc3 d6 4. d4 cxd4 5. Nxd4 Nf6 6. Be3

Foxy/Naive

Foxy/Naive

White is being foxy (inviting black’s game response) and a little naive because this move is absolutely nothing theoretically.

6…Ng4 Tasty!  White gets what he wants!  This move aims for adventure and risk. Kapengut passes by this point in his brief annotations without comment.  But a serious argument must be made for the simple 6… e5!? aiming for Be6 and d5 liquidation.  7. Nb3 (7. Nxc6 bxc6 8. Bc4 Be7 9. O-O O-O 10. Qd3 Be6 11. Rad1 Ng4 12. Bd2 Qb6 13. Bb3 Nf6 and white has zero) 7… Be6 8. Qd2 (8. Be2 d5! 9. exd5 Nxd5 10. Nxd5 Qxd5 11. Qxd5 Bxd5
12. O-O O-O-O is totally level) 8… d5 9. exd5 Nxd5  and once again I do not see any edge.  In fact, I think Joel Benjamin played this way versus me in some tournament, once. :) For example, 10. Nxd5 (10. O-O-O?  Bb4! 11. Bd3 Bxc3 12. bxc3 Qc7 13. Bc5 O-O-O! is just structurally horrible for white) 10… Qxd5 11. Qxd5 Bxd5 12. O-O-O O-O-O 13. c4 Be6 14. Rxd8+ Kxd8 15. Nc5 Bxc5 16. Bxc5 and white had zero in
Nakamura,H (2452)-Zilka,S (2182)/Oropesa del Mar 2001 although as you might guess Hikaru tricked his lower rated opponent in the ending .

Conclusion:  I don’t see anything wrong with 6. Be3 e5!? which takes the fun out of white’s schemes.

7. Bb5

See the comment suggestion for another playable move, 7. Bg5 — a minature Nakamura win over Fernandez in Bermuda 2002 that John Fernandez masochistically supplied.

7…Nxe3 8. fxe3 Bd7 9. Bxc6?! This is my choice in the Zaltsman game.

Due to black’s improvement on move 10 in my game, I think my move offers very little.

Kapengut chose the more foxy 9. O-O.  I will return to Kapengut’s choice after the Zaltsman game.

9… bxc6 10. O-O e6 (10… e5 {This logical move looks good!} 11. Qf3 f6 12. Nf5 g6 13. Ng3 Be7 and black was a little better and went on to win; Meszaros,A (2310)-Groszpeter,A (2495)/Hungary 1992/EXT 2000})

11. e5 If 11. Qf3 Qf6 12. Qe2 Qg5! makes sense and black stands well.

11… Be7 12. exd6 Bxd6 13. Ne4? A blunder but by this point white has very little.  13. Nf3 Qc7 14. Qd4 e5 15. Qh4 O-O 16. Ne4 f6 is not promising.

13… Bxh2+!  Ooopsie. Since I was young, I didn’t care about this blunder very much.  Sure enough, not too many moves later, Zaltsman was totally confused and white was winning! :)   I was completely amazed to see in the database a white win featuring this antique blunder of mine; Skjoldborg wound up winning vs. J. Christiansen, Copenhagen 2003, but of course it had nothing to do with this blunder. :)

14. Kh1 Qh4 15. Nf6+ gxf6 16. Nf3 Qg3 17. Nxh2 Rg8 18. Qe2 Rg6 19. Rf3 Qe5 20. Rd1 Rd8 The greedy 20… Rh6! 21. Rf4 Qxb2! 22. Rfd4 Rd8 23. Qd2 Qb7 and black should win.

21. Rh3 h6 22. e4 c5 Black is drifting!  Again 22… Qxb2.

23. Rhd3 Ke7 24. Nf3 Qc7 25. c4 Rgg8 26. e5! Ut-oh, white is asserting himself!

26…fxe5 27. Qxe5 Qxe5 28. Nxe5 Ba4 29. Rxd8 Rxd8 30. Rxd8 Kxd8 31. Nxf7+ Ke7 32. Nxh6 Bd1 33. Kh2 Kf6 34. Kg3 Ke5?

34… Be2 is a tougher try.  35. b3 Bd3 36. Kf4 Bb1 and the struggle continues. 

35. Nf7+ Kd4 36. Kf4 Kd3 37. g4 Kc2 38. b4 cxb4 39. c5 a5 40. c6 Be2 41. c7 Ba6 42. g5 a4 43. g6 b3 44. axb3 a3 45. g7 a2 46. g8=Q a1=Q 47. Qg6+ Kxb3 48. Qxe6+ Kc2 49. Nd6 Qf1+ 50. Ke5 Kc3 51. Ne4+ Kb4 52. Qb6+?

Here wa a nice win. 52. Qd6+! Ka5 53. Qa3+ Kb5 54. Qc5+ Ka4 55. Qb6; also winning was 52. Qe7+ Ka4 53. Nc5+ Kb5 54. Nxa6.

52… Qb5+ 53. Qxb5+ Kxb5 54. Kd6 Bc8 55. Nf6 Kb6 56. Nd5+ Kb7 57. Ke7 Bh3 58. Kd8 Kc6! I can’t break the blockade!  59. Nf4 Bg4 60. Ne2 Kd6 61. Nd4 Bh3 62. Nf3 Bg4 63. Ng5 Kc6 64. Nh7 Bh3 65. Nf6 Bf5 66. Ne8 Bh3 1/2-1/2

A titanic Lone Pine (in Death Valley, CA) Wild West blunderfest!

Now, back to the Kapengut game.

Recall 9. O-O was played in Kapengut-Pasalic.  The first interesting point: 9…g6 is less bad than prior evidence suggests.  It’s not good; just not losing. :)

9. O-O g6 10. Bxc6 bxc6 11. Qf3 f6 12. e5 dxe5 13. Nxc6 Qc8 14. Nxe5 fxe5 15. Qf7+ Kd8 16. Rad1 has been seen in practice, and in a prior game the losing 16…Kc7?? was played.    Far better is the clever 16… Bh6 and black has significant defensive resources.

The game went on 9. O-O e6 10. Bxc6 bxc6

Kritische

Kritische

The absolutely critical moment.   Kapengut played a move that leads to equal chances.

11. Qf3 Qf6 12. Qe2 and here Pasalic played the passive 12…Qd8? and white got the upper hand with a trick that is thematic for this variation, the e4-e5 break.  Much stronger is 12…Qg5! with the simple point of stopping white’s e4-e5 trick that occurred after 12…Qd8?.  As you might guess, 12…Qg5! has been seen in lots of games with decent black results.  From Kapengut’s own experience, after 13. Rf3 Qc5!? the game was about level but black managed to win eventually in Kapengut-Giorgadze 1969.  Alternatively 13.  Rf3 Be7 is also level and eventually drawn in Kapengut-A. Ivanov Minsk 1985.

Going back to move 11, the immediate break 11. e5!? is interesting and has been tried many times.   Recall I tried it in the Zaltsman game. 11…dxe5? 12. Qh5! is a big edge to white and 11…d5 12. Qf3 Qe7 13. b4! looks familiar with a white plus.

The correct move which took Vitaly about 10 microseconds to find is 11…Be7! 12. exd6 Bxd6 and it’s about equal.

The problem with 11. Qf3 is that it gave black that pesky improvement on move 12.  But the problem with 11. e5 is black has this “well known Soviet” equalizing technique.

Overall conclusion:  black can survive the 6…Ng4 adventure but again, 6…e5 looks simpler.

I would be interested to know reader experiences in this tricky line.

 

The Fabulous 00s: The Smith-Morra, again?

September 26, 2009

Dealing with the Smith-Morra Again

The recent USCL Week 4 GOTW Esserman-Bartell put the Smith-Morra on the map yet again!  I thought it was dead and gone ever since Smith-Evans and Smith-Mecking, San Antonio 1972.

The Flexible Variation

After listening carefully to Manest (Alex Lenderman) material presented on ICC Chess.FM, I came up with improvements for black in what I think should be the main line of defense,

1. e4 c5 2. d4 cxd4 3. c3

Losing a Center Pawn for....

Losing a Center Pawn for....

White gambits a center pawn for space and a lead in development. If black can catch up in development without making any concessions, he will be left with that extra pawn.  The best defensive lines always involve being careful not to make concessions.

3…dxc3 4. Nxc3 Nc6 5. Bc4 d6 6. Nf3

And now I term the “Flexible Variation” the careful 6…a6!? leaving the option of Bc8-g4 open.  It is very appealing to me not to shut in the B/c8 quite yet.  However and of course, thousands of games have seen black defend with an early e7-e6 as well.  The “Flexible Variation” was espoused by GM Evans all those moon ago (tournament book, San Antonio, 1972).

A manuscript in PDF format on the Flexible Variation (Lenderman white suggestions  with my additional lines) has been very popular with thousands of downloads. The amusing thing about many of the lines in the manuscript is that black manages to get an attack on the white king when white overpresses, a highly unusual occurrence in this variation!   I think this is the way to play that is the soundest coupled with the most chances for counter-attack and victory.  However, there is a more solid option, namely…

The Solid Gulko Defense

We note in the Esserman-Bartell game, black chose to shut in the B/c8 with an early ….e6 which is perfectly sound if he plays accurately.  In fact, a Lenderman-Gulko game did see black play the right way so we should mention it.  I have no doubt that Gulko’s defense was taught to thousands of school kids in Soviet chess academies but since we don’t have those, Bartell was left out in the proverbial cold.

1. e4 c5 2. d4 cxd4 3. c3 dxc3 4. Nxc3 Nc6 5. Bc4 d6 6. Nf3 e6 7. Qe2 Be7 Note Gulko plays e6 and Be7 before Nf6.

8. O-O Nf6 9. Rd1 e5 and now Lenderman went wrong with the illogical 10. Bb5? Bg4 11. Qc4 O-O 12. Bxc6 Rc8 and white had a bad game.  Gulko duly won. I think this was a World Open a few years back…?

The question is, what does black do if white plays normally?

Well, let’s say he gears up with a3 and b4 as Esserman played in the Bartell game.

10. a3 O-O 11. b4 Be6! Black is smart to not play a6 yet.  It is much more important to get development completed fast to check what white is up to.  This well-timed …Bc8-e6 is just in time to neutralize white.

As Solid as Gulko

As Solid as Gulko

And now… nothing is really going on!

12. Bxe6 fxe6 13. Qa2 Qd7 is actually slightly better for black since 14. Ng5 Nd8! leads nowhere; and on 12. Nd5 black has the luxury of ignoring it and playing 12…Rc8!.   This is smart because white gets nowhere with 13. Nxe7+ Qxe7 winning the bishop pair but getting rid of his own most active piece and black is quite solid with an extra pawn.

Note in the Bartell game black incautiously took on d5 at a bad moment, after wasting time with Bc8-d7-e6, and got driven completely back and flattened.  He also didn’t want or need the move b7-b5.

Conclusion:  The Gulko Defense is smart because we dispense with …a6 and get on with development to neutralize white’s initiative.

Overall Conclusion:  It’s a tossup to play solidly (the Gulko Defense) or try the sharp counterattacking ideas in my “Improved Manest Flexible Variation” which starts with 6…a6 reserving the possibility later of …Bc8-g4.  The latter variation probably offers more winning chances and so appealing to Sicilian players….

2nd Overall Conclusion:  Any Sicilian Player needs to be ready with one of these.

Lesson by Analogy

Take a quick look at the Esserman-Bartell game score.

1.e4 c5 2.d4 cxd4 3.c3 dxc3 4.Nxc3 Nc6 5.Nf3 d6 6.Bc4 e6 7.0-0 Be7 8.Qe2 Nf6 9.Rd1 e5 10.Be3 0-0 11.Rac1 Bd7 12.a3 a6 13.b4 b5 14.Bb3 Be6 (obvious time-wasting, much better and perfectly playable was 14…Rc8!  Black can always do Be6 later if need be, without tactical problems) 15.Nd5 Bxd5? (15…Rc8! is still the most careful! After, e.g., 16. h3 (what else?) now black can safely play 16…Bxd5 17. exd5 Nb8 with a fighting middlegame in prospect, 18. Nxe5?? fails to 18…Rxc1.  The fact that the BR is on c8 makes all the difference.) 16.exd5 Nb8? Despite the earlier inaccuracies, this is really the huge blunder.  16…Na7! and 17. Nxe5? does not work due to 17…dxe5 18. d6 Bxd6 19. Bc5 Nc8!.   After, e.g., 17. h3 Qd7 black is not by any means losing.  It’s not optically nice with the N on a7 but at least he has an extra center pawn.

17.Nxe5! It’s gone already but it was pleasing to GOTW judges.  They don’t like defense or a well-contested game except for, apparently, Michael Aigner and Greg Shahade judging from the post-GOTW commentary.

17…dxe5 18.d6 Bxd6 19.Bc5 Bxc5 20.Rxd8 Bxf2+ 21.Qxf2 Rxd8 22.g4 a5 23.g5 Nfd7 24.Qxf7+ Kh8 25.Qe7 Rf8 26.Qxf8+ Nxf8 27.Rc8 Black resigns 1-0

Given our discussion of the Gulko defense, where is the key improvement?  Yes, you guessed it, 11…Be6! is the right move.

11...Be6!  The Right Defense!

11...Be6! The Right Defense!

In defense of white’s opening choice, after 11…Be6! the wild wing lunge 12. b4! (something Esserman likes to play) black is only equal after 12…Nxb4 or 12…Bxc4; no trace of an advantage.  The game will fizzle out and sail into Draw Harbour.  There are some other kooky lines here too.  After 11…Be6 12. Bxe6 fxe6 white again can try the wild 13. b4 – a move I’ve seen Esserman play in similar situations.  Black can defend with 13…Ng4! 14. Bc5 Qe8! 15. Bxd6 Bxd6 16. Rd6 Qe7! lining up the rook and the b4 pawn.  Or, 13…Ng4! 14. b5 Nxe3! 15. Qxe3? Nd4! and black stands well due to the tactical point 16. Nxd4 Bg5! – OUCH!  Better would be 15. fxe3 Na5 16. Nxe5 and at least white got his pawn back at the cost of structure.  That position is equal after 16…Qe8 or 16…Bg5.

Finally, a variation from Outer Absurdistan: 11…Be6! 12. Bd5 Ng4 13. Bc5!? Nf6 14. Be3 Ng4 repeating!  Black can also risk 12…Qe8 to play on or tempt white into the amusing 12…Bxd5 13. exd5 Nb8 and hope white plays 14. Nxe5 analogous to the Bartell game.  If 14. Nxe5 the whole thing might blow up in white’s face: 14…dxe5 15. d6 Bxd6 16. Bc5?? Bxc5 17. Rxd8 Rxd8 18. Qxe5 Bxf2!+ (This old tactical chestnut!) and black wins.  Or, 16. Nb5 Ne8 17. Bc5 Nc6! and black is better.  Bartell unfortunately allowed really one of the only structures where the Nxe5 trick works. Usually it backfires as in these lines.

Postscript

I am particularly interested in reader comments on the Flexible Variation PDF manuscript.

The Fabulous 00s: USCL Week 3 OOTW

September 18, 2009

2009 USCL Opening of the Week – Round 3

IM Jonathan Schroer – GM Joel Benjamin King’s Indian Defense

Two stalwart denizens of the 1980’s Manhattan Chess Club (located at the world-famous Carnegie Hall) go at it in 2009-style online combat.

1.d4  Nf6  2.c4  g6  3.Nf3  Bg7  4.g3  0-0  5.Bg2  d6  6.0-0  c6  7.Nc3  Bf5!?

Not Incredibly Strong but Not Stupid

Not Incredibly Strong but Not Stupid

There’s something positionally appealing about setting up a d6,c6 pawn chain, getting this bishop out, and preparing a later d5.  In a related setup, black can try Nc6 (instead of c6) and then B to g4.  Then his idea is hit in the center with e7-e5 after the N on f3 is diverted or traded.

For example, Ron Henley – MG Lone Pine 1980 went

1. d4 Nf6 2. Nf3 g6 3. g3 Bg7 4. Bg2 O-O 5. O-O d6 6. c4 Nc6 7. Nc3 Bg4!? Unusual but interesting.  I can recommend this for further research to KID explorers out there.

8. Ne1 Qc8 9. b3 e5 10. d5 Ne7?

Here I go wrong and go ‘passive’.  The bubbly 10… Nd4! is correct with level chances. For example, 11. f3 Bh3 12. e3 Bxg2 13. Kxg2 Nf5 14. Nc2 c5! and black is fine.

11. f3 Bh3 12. e4 Bxg2 13. Kxg2. White has a definite pull now and I was lucky to draw.

Let’s return to the diagram position.  What should white do?  This is the key theoretical moment.

8.b3?! White is giving too much respect to black’s offbeat idea.  Our first guess based on prior evidence is that 8. Ne1! is correct. It accomplishes several aims.  Mostly, it aims to establish a white square pawn chain and induce black to trade B/f5 for B/g2. Secondly, it prevents Nf6-e4 which is strong in the game!

Let’s look at 8. Ne1! more closely.  We only give it an exclam here due to its success statistically in ChessBase prior games. As we shall see, this may be misguided.

After the possible followup 8…Qc8!? 9. e4 Bh3 10. f3 Bxg2 11. Kxg2 we reach another critical moment.  In practice, white has been scoring very highly here with his space advantage.  However, a single database game stands out for an interesting black response:

11. … c5! An amazing two-step with the black c-pawn.  It makes sense!  Rather than wait passively for a white build-up, black takes action to clarify the structure.  On the other hand, WEAK is 11…e5? 12. dxe5 dxe5 13. Be3! with a pleasant exchange-KID style safe edge for white, who has gotten rid of his problem child light squared bishop!  (Don’t remind Bruci Lopez about Exchange KIDs after he lost to Jesse Kraai in Weak 3 action, apparently an Altounian “special” delayed exchange variation because white cannot lose.  And who, after all, wouldn’t mind a KID where white cannot lose!).

Let’s see this ingenious 11…c5!.

ootw3_001

Position after 11…c5!

12. dxc5 Qxc5 and black is OK; or

12. d5 Nbd7 (in Amann-Martinovic, Austria 1998, the weaker 12…Na6 was played but black still drew) 13. Nc2 a6 and black has an acceptable Benoni with level chances.  12…Nh5 is also playable.

Well, let’s see, we might have to re-think and go back.  Maybe 8. Ne1 is not so fearsome!  What else?  8. Nh4 has been tried by such luminaries as Karpov and Portisch but that’s not dangerous; the WN is offside there.  8. Qb3!? is another try which has some logic, after all black’s Bf5 unguarded b7.  After 8. Qb3!? Qb6 9. Re1!? (Wojo used to try this)

A Wojo Special

A Wojo Special

White emerges with a small edge after the optically scary 9…Qxb3(?!) 10. axb3 Bc2 11. b4 Na6 12. b5 Nb4 13. e4!.  Wojo was a big openings expert so it makes sense to focus further research on his idea.  Even so, black doesn’t have to take, and can play e.g. 9…Na6.  His position looks fine.

Conclusion:  there’s no clear path for a white advantage in this KID sideline!

Returning to the game, recall that Schroer has reacted cautiously and rather passively with 8. b3.  This permits…

8… Ne4! Black is completely OK already; an opening success. In subsequent play Schroer vacillated between “solid” and “aggressive” with predictable results.

9.Bb2  Nxc3  10.Bxc3  Be4  11.Qd2  e6  12.Qe3  d5  13.Bh3  Bxf3  14.Qxf3  f5  15.Qd3  Nd7  16.f3  a5  17.Kh1  Qg5  18.Bg2  Qh5  19.Qe3  Rfe8  20.Qd3  Nf6  21.e4  dxe4  22.fxe4  Rad8  23.Rad1  c5  24.Bf3  fxe4  25.Bxe4  Ng4  26.Qe2  Rf8  27.Bf3  Rxf3  28.Rxf3  Nxh2  29.Kg2?

This has nothing to do with the opening, but the inhuman machine finds a way for white to get a half point here. 29. Qxe6+! Kh8 30. Rf7!! Qxd1+ 31. Kxh2 cxd4 (31…Qc2+ 33. Kh3 Qxc3 34. Rxg7! and draws) 32. Bxa5 Qh5+ 33. Kg1 Qxa5 34. Qe7 Rg8 35. Rxg7! with a draw!  What a line!

29…Qxf3+  30.Qxf3  Nxf3  31.Kxf3  b6  32.Ke4  cxd4  33.Rd3  e5  34.c5  bxc5  35.Bxa5  Ra8  36.Bb6  Rxa2  37.Bxc5  Re2+  38.Kf3  Re1  39.Kf2  Rc1  40.b4  e4  41.Ra3  e3+  42.Ke2  Rc2+  43.Ke1  Be5  44.Ra8+  Kf7  45.Rf8+  Ke6  46.Re8+  Kd5  White resigns 0-1

The Fabulous 00s: Week 2 USCL Opening of the Week (OOTW)

September 12, 2009

Week 2 USCL OOTW

In a GM matchup from round 2, we have Pascal Charbonneau (NY) tangling with GM Gregory Serper (SEA) in my favorite variation, the Sicilian Kan.  Surprisingly, Serper goes wrong early and Charbonneau won convincingly.  This sharp Sicilian Kan is this week’s Opening of the Week (OOTW) and we can learn a lot about move orders, nuances, and getting past the opening for black!

The raw game score:

Charbonneau (NY)-Serper (SEA)   Sicilian Kan


1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6 5.Bd3 Nf6 6.0-0 d6 7.c4 Be7 8.Nc3 0-0 9.Qe2 Re8?! 10.Kh1 b6 11.f4 Bb7 12.Bd2
This rather primitive set-up is the favorite set-up across all rating ranges when I play ICC blitz. Therefore, black should be ready for it.

12…Qc7? Oops!  An unfortunate choice that sends black down the drain.

Just to show that the Kan poses problems in quick play, here is a quick digression M. Ginsburg – D. Gurevich, G/30 Champs., Milwaukee, WI, 2002.
1. c4 c5 2. Nf3 b6 3. Nc3 Bb7 4. e4 d6 5. d4 cxd4 6. Nxd4 Nf6 7. Bd3 e6 8. O-O Nbd7 9. Qe2 a6 10. b3 Be7 11. Bb2 O-O 12. Rad1 Re8 13. f4 Bf8? 14. e5!

Oops! Black has forgotten about this possibility in a turn of events eerily similar to the current game we are analyzing.

14…dxe5 15. fxe5 Bc5 16. Na4!

White is winning.
16… Nxe5 17. Qxe5 Bd6 18. Qe2 Qc7 19. Rxf6 Bxh2+ 20. Kh1 Qg3 21. Rxf7!  The easiest. 21… Kxf7 22. Qh5+ Ke7 23. Qxh2 Qxh2+ 24. Kxh2 1-0 Dmitry didn’t have a chance after his miscue on move 13.

In another digression, just to show the Kan can create the pre-conditions for an upset, here is the great GM Dzindzihashvili taking too many chances and fumbling the ball against a young, inexperienced player in Chicago 1979.

1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 a6 5. Bd3 Nf6 6. O-O d6 7. c4 g6?! 8. Nc3 Bg7 9. Bg5 Nbd7 10. Kh1 b6 11. f4 Qc7 12. f5 gxf5 13. exf5 e5 14. Ne6! fxe6 15. fxe6 O-O 16. e7! Bb7 17. exf8=Q+ and white went on to win, M. Ginsburg – R. Dzindzihashvili, Chicago Masters/Experts 1979.

A final digression showing the dangers, with apologies to Viktor Korchnoi who clearly wasn’t fully awake that day,

1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 a6 5. Bd3 Bc5 6. Nb3 Ba7 7. c4 Nc6 8. O-O Qh4? 9. N1d2 Nge7 10. c5!  Yuck! 10…Ne5 11. Be2 b6 12. f4 N5c6 13. Nc4 bxc5 14. g3 Qh6 15. f5 Qf6 16. fxe6 Qxe6 17. Nd6+ Kf8 18. Bc4 1-0 Calvo-Korchnoi, Havana Olympiad 1966.

But fear not, Kan supporters.  This cagey opening can, and should, live!
Returning to Charbonneau-Serper, white strikes with the obvious but pleasing

13.e5! Nfd7 14.f5! … and White is completely winning already.  A very depressing opening tableau for black.

14…Nxe5 15.fxe6 Bf6 16.Nd5 Bxd5 17.cxd5 Nxd3 18.Qxd3 fxe6 19.Nxe6 Qf7 20.Qg3 Ra7 21.Bc3 Nd7 22.Qxd6 Qe7 23.Qg3 Bxc3 24.bxc3 Nc5 25.Rae1 Nxe6 26.Rxe6 Qd8 27.Qe3 Rae7 28.Qxb6 Qxb6 29.Rxb6 Rc7 30.d6 Rf7 31.Kg1 a5 32.c4 Rxf1+ 33.Kxf1 Kf7 34.c5 Ke6 35.Rb7 Kd5 36.Rc7 Black resigns 1-0

So what happened?  Serper didn’t react properly to Charbonneau’s common club-player plan of Bd2 and e5 (often with Rae1 thrown in).  The trick is that Bd2 tangles white’s minor pieces up on the d-file and black has to be ready to find tactical chances to exploit that tangle.

Let’s explore this a little bit more.   First, we take as already on the board black’s 9th move which looks a little fancy (delaying queenside development), but is OK.  White has just played 12. Bc1-d2 with obvious intentions.

Position after White's 12th move in Charbonneau-Serper

Position after White's 12th move in Charbonneau-Serper

Here, as we know, Serper played 12…Qc7? which loses for tactical reasons.

To exploit the tangle on the d-file after e4-e5, there are two black methods – placing a rook on d8 (after Qc7), or using the queen herself from d8.  Black can’t do the first method here, since he’s already played the slow 9…Re8.  So he needs to let the queen sit on d8 a little while longer to hold up e5.  After looking at this second method, we’ll return to the game a bit earlier and indicate how black can use the first method with a more crafty move order.

Let’s see it. 12…Nbd7! The first point is after the natural build-up 13. Rae1, black has the surprising 13…Nf8! and white’s e5 is definitely not playable. So white has to resort to slow methods and black has time to mobilize his whole army – the dream of the Hedgehog player who seeks to punch later in the middlegame.   But what about the immediate 13. e5!? which certainly looks dangerous? This is critical, but black can hold.

12…Nbd7! 13. e5!?  dxe5 14. fxe5 Nc5! There is no time for half-measures.  This is a solid defense.  Interestingly, there is another sharp defense here, 14…Bc5!? — after the plausible 14…Bc5!? 15. exf6?! Bxd4 16. fxg7 f5! black is all right.  However, after the accurate 15. Nf3! black has problems.

15. exf6 Bxf6 16. Rxf6! I think it’s very plausible to think that aggressive Charbonneau would steer for this apparently devastating attack.   Besides, on any other white move, black simply regains the piece with a very good game.  However, black has resources here.

Which way to take back?

Which way to take back?

Position after 16. Rxf6! – Analysis

The key for black is psychological – don’t lose your head when it appears your king is getting ripped apart!  Objectively black is all right.  The correct recapture is 16…Qxf6!.  No points for 16…gxf6? 17. Qg4+ Kh8 18. Bxh7!! and the king IS getting ripped apart; white wins elegantly after 18…Kxh7 19. Rf1!! f5 20. Nxf5! – what a pleasure it is for white to play all these moves! – and black has no defense.

So we have on the analysis board 16…Qxf6!

After this, black can look forward to what former WC Boris Spassky valued most highly; piece activity.  His coordinated activity saves him after, for example, 17. Nf3 Nxd3 18. Qxd3 Rac8 or 17. Nb3 Nxd3 18. Qxd3 e5!.  In many variations, this mobile e-pawn generates plenty of play.  Overall, chances are balanced in this sharp fight of two minors against the rook.

Let’s see a nice sample variation on the analysis board.

16…Qxf6! 17. Nf3 Nxd3 18. Qxd3 Rac8 19. Rf1 Qf5! - a very pretty defensive resource.

Nice defense!

Nice defense!

After 20. Qe2 Qc2! black is hassling white big-time, and after 20. Qxf5 exf5 21. b3 Rcd8 you don’t need to be a rocket scientist to observe all black’s pieces are running on all cylinders with level chances.

Conclusion:  Serper’s slow 9…Re8 is indeed playable but he needed to be alert after white’s 12th and find this narrow road.

Let’s go back and try to set up black’s other method to deal with e4-e5, by placing a rook on d8.  How to arrange this before white blows up the center?   Here’s how to do it for all you Kan explorers in the audience:

1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6 5.Bd3 Nf6 6.0-0 d6 7.c4 Be7 8.Nc3 b6 (no castles just yet) 9. f4 Bb7 10. Bd2 Nbd7 11. Qe2 Qc7 12. Rae1 and we reach a key moment.

Black has to be careful

Black has to be careful

As any good beginner’s book will tell you, be extra-careful when your king is not yet castled.  Thus the principle idea of Ra8-d8, while good strategically here, is bad tactically.  12…Rad8? 13. Nd5! (the punishment) 13…exd5 14. exd5 Nc5 15. Bc2! and white is totally winning.  Black wants to play Rd8, to hold up the e5 advance, but has to get the move order right.  Thus correct here is the apparently dangerous 12…O-O! first.  Let’s see it.  The testing line to calculate, of course, is the e4-e5 push.  With white’s king on g1, and not yet on h1, black has additional tactical possibilities.  And this, in fact, is what justifies 12…O-O!.

12…O-O! 13. e5?! dxe5 14. fxe5 Bc5! Threatening d4 WITH CHECK  and this is the saving nuance. 15. Rf4 What else? No going back now. White is already hoisted by his own petard.

15…Nxe5! A common tactical trick when there’s a d-file tangle.  Kan players must always keep this trick in mind. 16. Qxe5 Qxe5 17. Rxe5 Rad8! and white is caught in a set of lethal pins, since 18. Rxc5 bxc5 does not help!  Seattle wins the game and the match!

Going back, 12…O-O 13. Kh1 allows black to realize his principle idea with 13…Rad8! and the game is level!

Conclusion:  black can achieve the R to d8 “method” to hold up e4-e5 in this white setup but must be wary of move-order tricks and traps.

Overall conclusion:  the Sicilian Kan lives!

The Fabulous 00s: 2009 USCL Round 1 Openings Roundup

September 3, 2009

Week 1 Noteworthy USCL Openings

In Week 1 2009 USCL opening theory action, I will defer Scorpions Games analysis to Levon Altounian and Alejandro Ramirez. I’ll just look at other games around the league.

By the way we got some “film” from the Scorpions playing site in Round 1.

Zaremba (QNS)-Esserman (BOS)  Dutch Defense Anti-Curdo

1.d4  f5  2.Nc3 A recent SOS article talked about the humorous gambit 2. Qd3!? d6 (or 2…d5) 3. g4!? fxg4 4. h3 with light square compensation.  I don’t know what the 2. Qd3 variation is called, but it’s funny.

2… Nf6  3.Bg5  d5  4.Bxf6  exf6  5.e3  Be6  6.Bd3 An old Anti-Curdo weapon from the 1980s aimed to take the fun out of it for black; I managed to beat John in a lengthy game in some New England Swiss.  Across the ocean, Winants and Jadoul in Belgium enjoyed this system too.  In fact, Winants even beat Z. Polgar once on the black side of it at Amsterdam 1990. Objectively, it is good for a safe if tiny edge.  White has to watch out for black’s “shattered” pawns becoming mobile in the middlegame and advancing.

6… Qd7  7.Nge2  Nc6  8.a3

Time for a black plan

Time for a black plan

8…Ne7 This self-blocking move is probably not the strongest, although it has been played by GM Arteshes Minasian.    GM Spraggett played more strongly vs Huss (2380) in Zaragoza 1996 with 8…O-O-O! 9.  Na4?! (white is probably advised not to do this and play instead 9. Nf4) 9…Kb8!  (note how black doesn’t give white any easy attacking toe-holds on the queenside) 10. b4 Qe8! and with careful play Spraggett has equalized and went on to win.

9.b3?! Stronger is 9. Nf4 Bf7 10. h4.  White is preparing Na4 to attack the black king once it goes queenside, but the crux of the matter is that it shouldn’t go there in these changed circumstances.

9…Bf7 Black could play the interesting 9…a6!?and then 10…Ng6 covering c5 versus knight leaps and preparing kingside play.

10.Na4  0-0-0? This is the major strategical miscue.  After 10…b6! keeping the knight out black is all right.  There might follow 11. c4 g6! preparing Bg7 and castles short with good counter-chances. In the game, white built up a decisive attack against the very lonely black king.

11.c4  Kb8  12.Qc2  g6  13.0-0  h5  14.c5 and white scored a crushing attacking victory.

Perelshteyn (BOS) – Vovsha (QNS)  Modern Defense

1.d4  d6  2.Nf3  Bg4  3.c4  Bxf3  4.exf3 Taking toward the center with 4. gxf3 merits serious consideration.

4…Nd7  5.Nc3  g6 Not a bad setup.

6.Be3  c6  7.Qd2  Bg7  8.Be2 It is more aggressive and possibly more promising to put this bishop on d3 since in the game black achieves equal chances soon.

8…Nb6  9.d5  Nf6  10.dxc6  bxc6  11.0-0  0-0  12.Rac1  d5! Black is fine.

Equal!

Equal!

13.b3  e5? Asking too much.  Black had the equalizing 13…dxc4!.  If 14. bxc4 Qxd2 15. Bxd2 Rfd8 16. Be3 Ne8! holds up Rfd1 and prepares Rab8 and Nc7 with equality.  If 14. Qxd8 Rfxd8 it simply transposes. The game is equal.

14.cxd5  cxd5  15.Bc5! and white went on to win.

Ludwig (DAL) – Lopez (MIA)  King’s Indian Saemisch

1.d4  Nf6  2.c4  g6  3.Nc3  Bg7  4.e4  d6  5.f3  0-0  6.Nge2  Nbd7  7.Be3  c5  8.Qd2  Qa5  9.d5  a6  10.Nc1 A common knight regrouping in Benonis but it’s not clear how much it offers.

Decision Time

Decision Time

10…Rb8 (?!) This move may not be necessary.  Black has the surprising 10…Ne5!? with the idea 11. Be2 Bd7 12. f4 Neg4 13. Nb3 Qc7 14. Bg1 (not keeping this bishop automatically gives black a good game) 14…b5! (just in time!) 15. h3 b4! and by hitting the e-pawn black has a good game.

11.Nb3  Qb4  12.Qc2  Ne5  13.a3  Qb6  14.Be2  e6  15.0-0  exd5  16.cxd5  Qc7  17.a4  Bd7 If 17…Nh5 then 18. g4! Nhf6 19. h3!  is a good answer.

18.h3?! 18. a5 looks natural and good.

18….b5  19.Nd2  Rfe8 19…b4 20. Nd1 is similar to the game.

20.Rfe1  b4  21.Nd1  Bc8  22.Rc1  Ned7? The typical Benoni device 22…b3! gives black good counterplay here.  Look at this nice shot: 22…b3! 23. Nxb3? Nxd5!! 24. exd5 Bf5! and white must play 25. Qd2 Rxb3 and black is better.  And after 23. Qb1 Rb4! black is obviously not complaining either.  Black is all right after the game move, but 22…b3! was stronger.

Here is the rest of the chaotic game in which Lopez “slimed” his opponent out of a winning position.

Friedel (SF) – Serper (SEA)  French Defense

1.e4 e6 A surprising departure from Serper’s favorite Kan. Although he lost to Friedel last year in the USCL with this, he also defeated GM Becerra in a nice game.

2.d4 d5 3.Nc3 dxe4 4.Nxe4 Be7 Shades of Bareev. I’ve been encountering this a lot on the ICC so it must be the new rage.

5.Nf3 Nf6 6.Bd3 Nxe4 7.Bxe4 c5 8.0-0 Nd7 9.c3 0-0 10.Bc2 Qc7 11.Re1 Rd8 12.Qd3 Nf8  13.Qe4

Bertholee Power!

Bertholee Power!

13…cxd4? After the correct move 13…Bd7!  2360-rated R. Bertholee  playing black had equality and held a draw vs highly ranked GM Lev Psakhis, Amsterdam 1990.

14.Nxd4 White has a plus now.

Bd7 15.a4 a6 16.a5 Be8 17.h4 Rd5 18.Bb3 Rxa5?? Black can’t do that!  A very bad blunder from Serper. He has to go back to d7 or d8 with a bad game.

19.Rxa5? Not Friedel’s day. 19. Bf4 won for white. 19. Bf4 Qc5 20. Rxa5 Qxa5 21. Qxb7 Qd8 22. Rd1! wins as black’s queen is aesthetically caught in a crossfire.  White still has a big plus after the game move.

19…Qxa5 20.Qxb7 Qd8 21.h5 Bf6 22.Bf4 h6 23.Bc2 The paralyzing 23. Bd6! was strong.

23…a5 24.Qe4 24. Nc6! Qc8 25. Ne7+! is terrible for black.  Here is the rest of the game where Serper refuted an unsound sacrifice. The noteworthy thing about the opening is the improvement mentioned for black on move 13.

Bryan Smith (PHI) – Peter Bereolos (TEN)  Ruy Lopez

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 d6 8.c3 0-0 9.h3 Na5 10.Bc2 c5 11.d4 Nd7 12.Nbd2 exd4 13.cxd4 Nc6 14.d5 Nce5 15.a4 Rb8 16.axb5 axb5 17.Nh2

So far, so good from black’s point of view.

17…g5??

This move should have been total suicide. From an equal game this horrible weakening?    There was no danger here.  For example, 17…Re8 18. f4 Ng6 with equality.   17…Bb7 is also fine with similar play.  Black was acting as if f2-f4 had to prevented at all costs but this certainly is not the case.

18.Ndf1 18. Qh5! is very strong.  When black makes the ugly move f6, white can go back later to e2 or d1 with his queen and carry on.   After 18…Qe8 19. Ndf1 he’ll have to play f6 and suffer.  The game move is fine too.

18…Kh8 19.Ng3 Rg8 20.Ng4? Black’s position is revolting after the obvious 20. Nf5.  After, e.g. 20…c4 21. Be3 or 20..Bf8 21. Bd2 white should win in short order.

20…Nxg4 21.hxg4 Bf6 22.Nf5 Ne5 23.Ra3 Bxf5  and black held a draw in a game Philly really needed.

Kudrin (PHI) – Shabalov (TEN)  Sicilian Dragon

1.e4  c5  2.Nf3  d6  3.d4  cxd4  4.Nxd4  Nf6  5.Nc3  g6  6.Be3  Bg7  7.f3  0-0  8.Qd2  Nc6  9.Bc4  Bd7  10.0-0-0  Rb8 When I first saw the “Chinese Dragon” in the pages of New in Ches, GM Gallagher heaped scorn on it.  Yet he only drew GM Chris Ward.   Since Kudrin plays the Dragon a lot, this is a funny opening choice.

11.Bb3  Na5  12.Bh6  Bxh6  13.Qxh6  b5  14.Nd5! GM Emmanuel Berg got nowhere with 14. h4 e5! with equality, Berg-P. Carlsson Halstahammar 2003.

14…e6  15.Nxf6+  Qxf6  16.h4  Qg7  17.Qg5!

One big exclam to cover all of white’s prior moves; he has a safe edge now.  Black is not helped now by 17…Nxb3+ 18. Nxb3! Rb6 19. h5! with a plus.

17… Qe5  18.Ne2! Give yourself tactical skill points if you noticed white could have played the unusual 18. Qxe5 dxe5 19. Nf5!? here and give yourself positional skill points if you notice black is OK in the resulting position.

18…Bc6  19.Rd2?! The bizarre 19. Nf4! is very strong, threatening to trade queens and play Nd3!

19…Rfd8  20.Rhd1  Nb7  21.Nf4! Still a good idea.  21…a5  22.a3  Re8? 22…a4! is stronger with only a small white edge.

23.Nd3? White would have a huge plus after 23. Qxe5! dxe5 24. Nd3! f6 (forced) 25. g4! and he controls the board.  With the game move he only has a small edge, and unfortunately for Philadelphia   Black went on to score a lengthy, dramatic victory in a tough ending.

And Did You Know?

In NIC magazine, GM Rustam Kasimzhdanov indicates his favorite movie is David Lynch’s Mulholland Dr. This is a bizarre choice for favorite movie, as I wouldn’t even rate it highly among Lynch’s own oeuvres.

A Final Shot
