The Fabulous 10s: Computer-Assisted Dragons

January 27, 2010

Or, Maybe, Computers NOT Assisting on Dragons in Holland

Random, bizarre move sequences appear on the board!  Or, maybe computers were NOT working – check the horrific blunder pair on moves 17 and 18!

[Event “Corus C”]

[Site “Wijk aan Zee NED”]

[Date “2010.01.26”]

[Round “9”]

[White “Li Chao”]

[Black “Robson,R”]

[Result “1-0”]

[WhiteElo “2604”]

[BlackElo “2570”]

[EventDate “2010.01.16”]

[ECO “B77”]

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 O-O 8. Qd2 Nc6 9. Bc4 Bd7 10. h4 Ne5

Since Robson was leading the tournament, this opening choice was a terrible idea! Why don’t American players have safety openings?  Now, OTOH (on the other hand), young Ray gets bravery points.  But if the Dragon is not his regular opening (and it is not), it is a monumental and perverse task to “get used to” its idiosyncratic patterns.  It’s a one-of-a-kind death-defying choice.

11. Bb3 h5

Personally I’ve always regarded this move (I believe popularized by Soltis first, maybe others?) with suspicion.  It increases the force of Nd4-f5 sacrifices in many lines.

12. O-O-O Rc8 13. Bg5 Rc5 14. Kb1 b5 15. g4 hxg4

Dangerous Deviation Alert!

16. h5

Deviation alert!  16. Bxf6! is a very dangerous try here, eliminating black’s most important defensive piece!  16. Bxf6 Bxf6 17. h5 gxh5 18. Nf5! Nxf3 19. Qh6 Rxf5!! (only this way!) 20. Qg6+ with a perpetual check!  Wow!  If black avoids a perpetual with 20…Bg7?, after 21. exf5 white is much better.  The text is an old try and “discredited” in the sense white gets no advantage.  But maybe it caught black by surprise.  Note that 16. Bxf6 exf6? 17. h5 gxh5 18. Qh2! Nc4 19. Bxc4 bxc4 20. Qxd6! gives white a big advantage.

16…Nxh5 17. Nd5

Old Theory Quiz: Black's best defense is.... ?

17…Nf6? (??)

Maybe my theory is out of date, but 17…Re8! 18. Rxh5 gxh5 19. Qh2 (as in an old Short game, Short-Mandl Germany 1986 where black botched the defense and went down in flames) is met by 19…gxf3! 20. Qxh5 Bg4! and black holds.  This happened in a game Lagumina – Magalotti, Forli 1991 and black indeed drew.

Note that also in the precomputer era, 19. Qh2 Rc4? 20. Bxc4 bxc4 21. Qxh5 with a big white edge happened in Karpov-Sznapik, Dubai 1986 Olympiad.

The computer shows no advantage for white after 17…Re8! – readers?

The game move looks really bad; i.e. immediately losing.  Is it possible Robson was making stuff up in this, the sharpest of all opening choices?

18. Bh6??

A monumental blunder in return. It’s impossible to say what Chao was thinking.   The guy is rated 2604 and he misses a win that any schoolboy would play – capture, capture, and mate!  Isn’t that the entire point of the Yugoslav Attack?

The elementary 18. Nxf6+ wins easily. If 18…Bxf6 19. Qh2! simply checkmates black. If 18…exf6 19. Bh6! forces 19…Bh8, since 19…f5 is crushed by 20. Bxg7 Kxg7 21. Qh6+ Kf6 22. f4 and wins. After 19…Bh8, white wins with the easy 20. Bxf8 Qxf8 21. Qh2 Qg7 22. fxg4 Bxg4 23. Rdg1 and wins.

What was in the water in this game? (or the Dutch pea soup?)

18…Nxd5 19. Bxg7 Kxg7 20. Qh6+ Kf6

Did Chao miss the king could run? Embarrassing! But look what happens!

21. exd5 Nxf3 22. Ne2?

22. Nxf3 keeps the balance.  Now Chao has overstepped even the bounds of an even game!

22…e5?

22…Bf5 consolidates and wins for black without too much trouble!

23. dxe6 Bxe6 24. Qf4+ Rf5 25. Qxg4 Kg7 26. Bxe6 fxe6 27. Nd4 Nxd4 28. Qxd4+ e5 29. Qxa7+ R8f7 30. Qe3 Qg5 31. Qd3 Qf6
32. a3 Rf2 33. Qh3 Qf5?

Apparently black was down to increments.  33…Kg8! was bad  (but not losing) for him after 34. Rxd6 Rf1+ 35. Rd1! but it was forced.  But doesn’t white’s play over the last few moves look pretty random?  Maybe he was in time trouble too.

34. Qh8+ Mate 1-0

For the gawking observers, what the HELL was going on this opening? Will we ever know?

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 80s: NYC’s ‘Bar Point’ Club and its 1980 FIDE International

January 19, 2008

Chess and Music

The Bar Point Club, on 14th street and 6th Avenue, New York City, was an extremely busy chess locus in the early 1980s. It was owned by a backgammon player for some time (readers, I have forgotten his name) and after that, noted chess organizer and politician Bill Goichberg owned it; after that Peter Malick (a card player, and associate of Wayne Kramer from the MC5 60’s Detroit rock group) took over. I only know that Peter knew Kramer because I met, to my shock, Wayne Kramer face to face in one of the crazy late Bar Point nights. I could come up with nothing more clever than “I really like the MC5” and Wayne retorted “Small world”, turned on his heel, and walked off. The Bar Point went defunct for rent non-payment in the the mid 1980s – no more quads, no more IM and GM tournaments, no more back-room poker where I used to play heads-up with Howie Lederer. Sometimes after (or before) a poker skirmish I would then do battle in chess in the front room with Howard (he was a USCF expert).

A Few Words on a Pure Gambling Game: Backgammon

As a side comment on backgammon – this gambling game with “checkers”, dice, and the “doubling cube” could be very profitable to those more skilled than their wealthy but deluded opponents. For exampe, IM Jay Whitehead made thousands in one night playing the owner of a New York City Greenwich Village jazz club owner (one of the major clubs, for example Village Gate, the detail escapes me), and then was generous enough to fund a trip for me and him to play in Lugano, Switzerland 1984 where I played, among other people, ex-WC Boris Spassky. I know the winnings was in the thousands because he woke me up in the middle of the night to help him count the fifites and hundreds that were bulging out of every one of his pants and shirt pockets. Poker is has some similarities with the vast pool of weaker players but the complicated-to-use-properly backgammon doubling cube, rewards more immediately the better analyst. Besides, it’s nice to own a nice Moroccan or Syrian artisan backgammon set. You could also play the simpler Turkish backgammon variant shesh-besh (with no doubling cube).

Some Actual Chess

In 1980 I made my 2nd IM norm with a strong finish. Let’s see some of the games.

Round 1. Bar Point International I

IM Margeir Petursson (ICE) – M. Ginsburg

Of course my opponent went on to become a famous Icelandic Grandmaster and also a very successful lawyer businessman.

1. c4 Nf6 2. Nc3 e6 3. e4 d5 4. e5 Ne4 5. Nxe4 Much safer is 5. Nf3 Nc6 6. Qc2, but then black has the surprising 6…Ng5!! TN – I used this to draw strong Canadian Kevin Spraggett in Toronto 1983. For example, 7. Nxg5 Qxg5 8. d4 Qh4 9. cxd5 Nxd4 10. Qd1 exd5 11. Nxd5 (11. Be3 Nf5 12. Nxd5 Bb4+ 13. Bd2 Qe4+ 14. Be2 Bxd2+ 15. Qxd2 Qxe5 and it’s equal. I don’t remember who showed me 6…Ng5!! TN, but it’s a really good novelty. Maybe I was the first to play it?

5… dxe4 6. Qg4 f5!? TN Black can also play 6… Bd7 7. Qxe4 Na6 8. Nf3 Bc6 9. Qb1 Nc5 10. d3 Nd7 11. d4 Bb4+ 12. Bd2 Bxd2+ 13. Nxd2 O-O 14. b4 a6 15. a4 Nb6 16. b5 with a total mess. The text move, 6…f5!?, is a novelty with great surprise value. Was I the first to play it? Again, I don’t remember who showed me. I was staying with Tisdall and Fedorowicz at the time; so maybe one of them.

pet1.png

Position after 6….f5!? TN. Who showed me this? Is this the first time it was played?

7. exf6 Qxf6 8. Qxe4 Nothing comes of 8. Nh3 Nc6 9. Be2 Qf5.

8… Nc6 9. Nf3 Bc5 10. Bd3? Much stronger is 10. Be2 e5 11. O-O Bf5 12. Qd5 Bb6 13. d4 Nxd4 14. Nxd4 Bxd4 15. Bh5+ g6 with a murky game.

10… Bd7 11. O-O O-O-O 12. Bc2 Nb4 13. Bd1?! Slightly more natural is 13. Bb1 Bc6 14. Qe5 b6 15. Qxf6 gxf6 16. Ne1 Rhg8 17. g3 Bb7 18. d3 Bd4 and black has a nice game.

13… Bc6 14. Qe5 Nd3 15. Qxf6 gxf6

pet2.png

Position after 15…gxf6. White is hog-tied.

The novelty in the opening could not have succeeded more. White is paralyzed and black should have no trouble winning this.

16. a3 a5?! The right move is 16… Rhg8! 17. b4 Bd4 18. Rb1 Be4! (I missed this move) 19. g3 Bxf2+ 20. Kg2 Bd4 and black is easily winning.

17. b4 axb4 Black can also play 17… Nxc1 18. bxc5 (18. Rxc1 axb4 19. d4 Bxf3 20. Bxf3 Rxd4 21. axb4 Bxb4) 18… Nd3 and he stands well.

18. axb4 Bxb4 19. Bc2 19. Ba3 Bxa3 20. Rxa3 Rhg8 21. g3 Nb2 is good for black, but not a decisive edge.

19… b6 20. Ba3 Rhg8 21. Bxd3 Bxf3 22. g3 Bxd2 23. Bc2 f5?! Once again I miss an easy and rather primitive variation: 23… Bc3 24. Rab1 Be2 25. Rfc1 Bd2 trapping the rook and wins.

24. Rfb1 Rg4 25. c5 bxc5 26. Bxc5 Rc4 27. Bb3 Rxc5 28. Bxe6+ Rd7 29. Ra2 Bc3 30. Ra3 Here, white lost on time; fortunate for me because I had been showing shaky technique so far.

0-1.

Black is on top, but not totally winning. For example, 30…Bd5 31. Bxf5 Bf6 32. g4 Kd8 33. Bxd7 Kxd7 34. Rd1 Bg5 35. h4 Be7 36. Rf3 Kc8 37. Rf5 c6 and the game goes on, with black having an edge but it remains to see if I can convert it.

In Round 4 I encountered New England junior Jim Rizzitano. I include the ratings at that time as a historical curiosity.

Mark Ginsburg – NM James Rizzitano (2352 USCF, 2225 FIDE) Round 4. Leningrad Dutch.

1. c4 f5 2. Nf3 Nf6 3. g3 g6 4. Bg2 Bg7 5. O-O O-O 6. d4 d6 7. Nc3 Nc6?! Of all the Leningrad Dutch lines, (7….c6 8. d5! MG-Sarkar US Ch 2006, 7….Qe8 MG-Bareev Naestved 1988 are popular) this one is the most positionally suspect.

8. d5 Ne5 9. Qb3 Ned7 Perhaps a little better is 9…Nxf3+ 10. Bxf3 Nd7 11. Bg2 Nc5 12. Qc2 and white keeps some edge. GM Anderssson as white managed to beat De la Villa Garcia, Pamplona 1998, in 43 moves in this line.

10. Qc2 Nc5 11. b4! Although many moves have been seen here, the text is obvious and strong.

11…Nce4 12. Bb2 This position has been seen OTB in other games; it simply favors white.

12…e5 Aagard-Rewitz, Aarhus 1999, saw 12…c5 13. dxc6 bxc6 14. Nxe4 fxe4 15. Nd4 and white has an edge. Aagard won in 40 moves. The double-double “A” is very aesthetic: Aagard played in Aarhus. 🙂 Black also was unsuccessful with 12…Nxc3 13. Bxc3 Bd7 14. Nd4 Qc8 15. Rac1 c6 16. dxc6 bxc6 17. b5 c5 18. Nc6 and white won in 48 moves, Haba-Trapl, Czechoslovakia 1994.

13. dxe6 Nxc3 14. Bxc3 Bxe6 15. Rad1 Qe7 16. Ng5 White did absolutely nothing clever and he has a huge edge. That means black’s opening was poor.

16…c6 17. b5 Bd7 18. Qd3 Ne8 19. Bxg7 Kxg7 20. Qd4+ Kg8 21. h4 h6 22. Nh3 Kh7 23. Rfe1 Rd8 24. e4 Qf7 25. exf5 Bxf5 26. Nf4 The easiest was 26. Qxa7 Nc7 27. Qb6.

26… Rc8 27. Bf3 Ng7 28. Qxd6 Qxc4 29. bxc6 bxc6

rizz80_1.png

Position after 29…bxc6. White to play and win.

30. Re7? A tactically alert player would find the immediately decisive and aesthetic 30. h5! gxh5 (30… g5 31. Ng6 Rfe8 32. Qf6 wins) 31. Re7 Rf7 32. Bd5! (interference theme!) and wins.

30… Qc3 31. Qd4 Once again, 31. h5! g5 (31… gxh5 32. Nxh5 and wins) 32. Ne6 Bxe6 33. Qxe6 Rxf3 34. Rdd7 Rxg3+ 35. Kh2 Rh3+ 36. Qxh3 Qxh3+ 37. Kxh3 Rg8 38. Rxa7 wins.

31… Qxd4 32. Rxd4 Kg8 33. Rxa7 Rf7 34. Rxf7 Kxf7 35. Rd6 c5 The last chance was 35… g5 36. hxg5 hxg5 37. Ne2 and it’s not all over yet.

36. Nxg6! c4 37. Bd5+ Ne6 38. Nf4 c3 39. Rxe6 c2 40. Rc6+ Ke7 41. Rxc8 Bxc8 42. Ne2 Bf5 43. Nc1 1-0

Middle Round Disasters

All was not sweetness and light. I suffered a nasty reverse playing the white pieces versus Icelandic future Grandmaster and World Championship candidate Johann Hjartarson. Recall that Hjartarson defeated Korchnoi in a match! And then I threw away a completely won game and lost ignominiously to the eventual tournament winner, now sadly retired from OTB play to pontificate and author various tomes, IM John Watson. It took GM Larry Evans in a newspaper column to rudely show me the winning line. Readers will commiserate when they see the diagrams tell the woeful story of the Watson game.

Round 5.

IM John Watson – M. Ginsburg English Opening

1. c4 John’s fearsome specialty. Not a bad move; I used it myself in numerous Mikenas Attack encounters (1. c4 Nf6 2. nc3 e6 3. e4!?, later taken up by Nakamura, e.g. Nakamura-Zarnicki 1-0 HB Global Chess Challenge, Minneapolis 2005).

1…Nf6 2. Nc3 c5 3. g3 e6 4. Nf3 b6 5. e4 Bb7 6. d3 d5? A really bad move. 6…Nc6 is fine for black.

7. cxd5 exd5 8. e5 Nfd7 Black has handled the first phase very poorly.

wat1.png

Position after 8…Nfd7. Black has a very poor game.

9. d4? A miscue in return. The surprising 9. Bh3! is extremely good for white. For example, 9…d4 10. Ne4 Bd5 11. O-O Be7 12. e6! fxe6 13. Nfg5 with strong pressure.

9…cxd4 Now black is OK again.

10. Nxd4 Nxe5?! This pawn grab looks and is too risky. The more sedate 10…Bc5 and much more sensible is quite playable for black.

11. Bb5+ Nbd7 12. Qe2 White had 12. Bf4! Bd6 13. O-O O-O 14. Nf5! with a big plus.

12…Qe7 13. O-O O-O-O 14. Be3 Kb8 15. a4 This idea is not bad,; 15. Rae1 is another valid way to handle the position.

15…g6?! The inaccuracy festival continues. This is rather slow. Correct is the challenging 15…Qf6!, e.g. 16. a5? Bc5! threatening to eat on d4 then fork on f3 with Nf3+. In that position, Black is fine and even has chances to gain the initiative. White should play 16. Bxd7! Rxd7 17. Bf4 Bd6 18. Ncb5 g5 18. Bxg5! Qxg5 20. Nxd6 with some advantage.

16. a5 Bg7

wat2.png

Position after 16…Bg7. Time to act.

17. b3?! Hesitant and weak. Correct is the simple 17. axb6 Nxb6 18. Ba6 and white has a big edge. And on 17….axb6? 18. Bf4! eyeing Nc6+ is completely crushing, e.g. 18…Qd6 19. Ba6 Bc6 20. Ncb5! and white wins. Also strong is the evident 17. a6! Ba8 18. Rfe1 with a bind.

17… bxa5? Another error. 17…Rc8! is correct, e.g. 18. Rfc1 Qb4! to lure the rook to a4: 19. Ra4 Qe7 and black is holding the position. Now 20. axb6 Nxb6 would hit the rook on a4 and let black have room to breathe (and defend).

18. Rfc1?! White had the tempting 18. f4! and black has to walk a narrow path just to not lose right away. He has to play 18…a6! (18…Ng4? 19. Nc6+ Bxc6 20. Bxa7+ wins) 19. Ba4 Rc8! 20. Rac1 Rc7! (Black must acquiesce to the inevitable loss of a piece; he has some pawns for it) 21. fxe5 Nxe5 and black is worse but not lost.

18…Rc8 19. Rxa5?! 19. f4! will transpose to the above note after 19…a6! 20. Ba4 Rc7! 21. fxe5 and white enjoys a sizeable plus.

19… Rxc3! This seems like desperation but in fact it’s black’s best try.

20. Rxc3 Qb4 21. Ra2? The situation is confusing. 21. Bd2 Qxd4 (21…Qxa5 22. Rc8+ is good for white) 22. Ra4 Qb6 23. Be3 Nf3+ 24. Qxf3 d4 25. Qf4+ Be5 26. Bxd4 Bxf4 27. Bxb6 Nxb6 28. Rxf4 Nd5 29. Rcf3 Nxf4 30. Rxf4 Rd8 31. f3 f5 32. g4 is a crazy sample line that fizzles into a draw. Still, the text is an outright blunder. White must have overlooked something.

21… Qxc3 22. Bxd7 Qd3! Strong! Black now has some hopes of getting the upper hand. This is the kind of move that white may have overlooked in preliminary calculations; now he gets really rattled.

23. Qe1?? A really bad blunder. Correct is 23. Bb5! Qxe2 24. Bxe2 Re8 25. Kf1 with a level game, or 25. Nb5 Nc6 26. Nxa7 Nb4 again with a draw. White must have hallucinated a mate or something, but this clunker just drops a piece.

23…Nxd7! I don’t know why I indicated 23… Qxd4? as good in my scorepad after the game. That move only seems to draw: 24. Bxd4 Nf3+ 25. Kf1 Nxe1 26. Bxg7 Rd8 27. Be5+ Ka8 28. Kxe1 Rxd7 29. Bd4 Bc6 and it’s equal. The text grabs a free piece and the game should be all over.

24. Bf4+ A last check before white has to give up.

wat3.png

Position after 24. Bf4+. One last “puzzle” to solve, and I fail ignominiously.

24…Kc8??? What the heck – a mutual hallucination? Maybe I was low on time, but my scorepad doesn’t have the times in it. Did Watson give off weird mental vibes after his irrational 23rd that I “caught” and “echoed?” Only a while after the game (I was really eager to forget it) did I read GM Larry Evans column that “informed me” that 24… Ka8 would win. White doesn’t have any threats, let alone a potential mate. Could I have overlooked that 25. Qa5 Bxd4 guards a7? It is true that backward diagonal moves are often overlooked … More likely, I thought the desperado 25. Rxa7+ “worked”. In reality, 25. Rxa7+ Kxa7 26. Qa5+ Ba6 27. Qc7+ Ka8 28. Qc6+ Bb7 29. Qa4+ Qa6 also wins for black. Pretty simple stuff. Whatever the case, the text is suicide and after white’s next, it is clear black loses many pieces all with check. Did I really do this, move my king to a losing square when the other square obviously wins? Yes, I did!

25. Qc1+ I’m losing. A serious blow to my IM norm chances. Boo! I am now losing to John Freakin’ Watson.

25…Kd8 26. Qc7+ Ke8 27. Re2+ Ne5 28. Bxe5 Bxe5 29. Qxe5+ Kd7 30. Qe7+ Kc8 31. Rc2+ Kb8 32. Qe5+ 1-0 Ugh! I was really angry. Time to rebound! The winner of this game won the tournament, with a big score of 8.5 out of 11, reaffirming the adage ‘winners make their own luck’.

Theory Interlude: Blowing Kudrin’s Mind in a Dragon

In the eighth round, I had the opportunity to surprise Kudrin with a TN in the Dragon. This doesn’t happen often to the well-prepared Sergey. He employed my TN with white the next year!

M. Ginsburg – Sergey Kudrin, Round 8 Sicilian Dragon, Yugoslav Attack.

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 The Yugoslav attack. The only real way to deal with this opening. Anatoly Karpov had some beautiful wins with it, including a famous Informant masterpiece over Viktor Korchnoi (WC Match), in this variation.

7…O-O 8. Qd2 Nc6 9. O-O-O! This move cuts down on the amount of material white has to know. For that reason, it has high practical value.

9…Nxd4 A whole different story is 9… d5 10. exd5 Nxd5 11. Nxc6 bxc6 12. Bd4 e5 13. Bc5 Be6 14. Bc4 Re8 15. Ne4 h6 16. g4 f5 17. gxf5 gxf5 18. Rhg1 Kh7 19. Qg2 and white won, 1-0 Fedorov,V (2425)-Eletsky,E/Oviedo 1993. There have been many games in this line, and current thinking is that white has a small edge.

10. Bxd4 Be6 11. Nd5 White can try 11. Kb1 Qc7 12. Bb5 a6 13. Ba4 b5 14. Bb3 b4 15. Na4 Rab8 16. h4 [If 16. Bxe6 fxe6 17. b3 Qc6 18. h4 Rfd8? (Better is 18… Nh5 19. Bxg7 Kxg7 20. Qe3 h6 21. g4 Nf4 with equality) 19. g4 e5 20. Bb2 h6 21. g5 Nh5 22. gxh6 Bf6 23. c4 Nf4 and white won, 1-0 Nijboer,F (2534)-Janssen,R (2445), Wijk aan Zee 1999.] As Bernard Zuckerman told me, 11. Bb5? right away is really bad: 11…Qa5 12. Ba4 Rfc8! and white cannot complete his defensive idea and is hence lost (BZ). The computer verifies Bernie. For example, 13. Bb3 Bxb3 14. axb3 Qa1+ 15. Nb1 a5! and black has a big plus.

11… Bxd5 12. exd5 Qc7 13. Kb1 Rac8 (13… Rfc8 14. Rc1 a6 15. h4 e5? 16. dxe6 fxe6 17. g4 Qf7 18. h5 e5 19. hxg6 hxg6 20. Be3 d5 21. Bh6 Bh8 22. Qh2 Nh7 23. Bd3 Rc6 and white won, Kuzmin,G (2495)-Alterman,B/Voroshilovgrad 1989.

14. Rc1! TN

kud_1.png

Position after my novelty 14. Rc1! TN

I know this is a good move, because Kudrin adopted it as white the next year, 1981! I also have vague memories of discussing this move with someone (perhaps they told me about it) but I am not sure about that. Previously seen was the anemic 14. c4? b5! 15. Rc1 (15. b3 bxc4 16. bxc4 Rb8+ 17. Ka1 Rb6 18. Be2 Rfb8 19. Rb1 Nd7 20. Bxg7 Kxg7 21. Qd4+ Kg8 22. Rxb6 Rxb6 23. Rb1 Rxb1+ 24. Kxb1 Qa5 and black went on to win, 0-1 Dhar Barua,S (2225)-Shaw,J (2390)/Manchester 1997. 15… Rb8 1/2-1/2 Bertok,M-Vidmar,M/Ljubljana 1955.

14… a6 The passive 14… Nd7 is good for white: 15. Bxg7 Kxg7 16. h4 Nf6 (16… h5 17. g4 Rh8 18. Qd4+ f6 19. Qxa7) 17. h5 gxh5? (17… Nxh5 18. g4 Nf6 19. Qh6+ Kg8 20. Bd3 Qc5 21. g5 Qe3 22. f4! Qxf4 23. Rcf1! wins) 18. Bd3 {1-0 Smeets,J (2311)-Didderen,G/Hyerois 2001}

15. c4! Also playable is 15. h4 e5 16. dxe6 fxe6 17. g4 e5? (Correct is 17… Qc6 18. Be2 Nd5 19. Bxg7 Kxg7 20. h5 Nf4) 18. Be3 Qc6 19. Be2 Nd5 20. h5 Nxe3 21. Qxe3 Qc5 22. Qb3+ d5 23. hxg6 hxg6 24. Rcd1 Rfd8 25. Bd3 and white won, S. Kudrin (!) Mark,D (2256)/Palo Alto 1981. This game proves the worth of the 14th move novelty! The position on the board now is simply good for white.

15… Rfe8 The rash ‘breakout’ 15…b5? 16. cxb5 Qxc1+ 17. Qxc1 Rxc1+ 18. Kxc1 Rc8+ 19. Kb1 Nxd5 20. Bxg7 Kxg7 21. bxa6 is obviously very good for white.

16. Bd3 e6 17. dxe6 fxe6 and I had a huge edge with the bishop pair and black’s hanging pawns. Unfortunately, I only drew eventually and I can’t find the scoresheet. The fact that Sergey used this as white in the very next year is heart-warming (a fact I didn’t know until I looked it up recently).

1/2-1/2

The Exciting Conclusion of the Tournament

So in the last two rounds I needed a perfect 2-0 score to get the norm. In the next to last round I was black against future IM Walter Shipman and in the last round I was white against future FM Dan Shapiro. Well, I got the job done very smoothly and easily against the normally stodgy and solid Shipman. But the Shapiro game was another story. I posted them in a separate installment – the last game in particular, a nervy norm game, was not for the faint of heart.

The Classic 70’s Part 10 – Odds and Ends

July 16, 2007

Here are some funny games that I played during the 70s featuring some classic personalities.

Region III Championship 10/24/76        40/2

Mark Ginsburg (2173) – Charlie Powell (2304)

Reti/Gruenfeld

Charlie was a real Southern gentleman with a discernible Virginia accent. Unflappable even in severe time trouble, he was a wizard with the initiative. However, he was extremely erratic. Sometimes he lost badly as in this game and sometimes he played like a genius. For example, he was unstoppable in the old National Chess League, or NCL, (that was played via telephone) in the 70s on the Washington Plumbers squad (named after the Nixon Watergate incident). You can also see how well he did in Virginia State Championships. Kudos to IM Greg Shahade for resurrecting the NCL into a new Internet form (eminently logical) – now named US Chess League. The Washington Plumbers also recruited, at times, GMs Kavalek and Andersson but that’s another story. I played on occasion, as did Robert Eberlein, John Meyer, future World Junior Champ Mark Diesen, and Robin Spital.

Charlie played a particularly good game vs IM John Peters in the NCL that I will find. He was a swashbuckling figure who would arrive late, dressed a bit like Errol Flynn, on his motorcycle. He would often have a lady friend at his side during the game. He was a natural talent of the first order, much like Michael Rohde and Michael Wilder after him.

Tragically, Charlie passed away on the West Coast at a young age. The Mechanics Institute had a Charlie Powell Memorial tournament and referred to him as one of the Bay Area’s top players in the 1980s – although I had lost track of him in this time period.

1. Nf3 d5 2. c4 Nf6?! The first misstep. 2…c6, 2…e6, 2…d4, and 2…dxc4 are all normal.

3. cxd5 g6? 3…Nxd5 leads to a bad position but the text is simply a blunder.

4. e4! Oops! Charlie must have been asleep at the wheel. Since 4…Nxe4? 5. Qa4+ is not playable, white is just winning.

powell1.png

4…Bg7 5. Nc3 O-O 6. Be2 c6 7. dxc6 Nxc6 8. d4 a6 9. O-O b5 10. d5 Na5 11. e5 Ne8 12. Bf4 Bb7 13. b4 13. Qd4! was the most accurate move intending 13… Rc8 14. b3! e6 15. Rad1 and black can hardly move.

14. Rc1 Nc4 15. a4 bxa4? 15…Nc7 was the only chance to keep playing.

16. Qxa4 Nb6 17. Qa5 Nxd5? A further blunder, but it didn’t matter anymore.

18. Nxd5 Black’s pieces are tied to each other and overloaded, so he loses a lot of material. For example, 18…Qxa5 19. bxa5 Rxc1 20. Nxe7+! (classical zwischenzug) and white remains up a piece. Black resigned.

4/17/1977

Sal Matera (2421) – Mark Ginsburg (2157) Round 3, 40/2

Sal Matera from New York City became an IM in the 1980s along with Ken Rogoff (who went on to become a GM) and Andy Soltis (ditto).

 

1. d4 g6 2. e4 Bg7 3. Nc3 d6 4. Nf3 a6 5. a4 Nf6 6. Be2 O-O 7. O-O b6!?

matera1.png

I was too young to utilize chess psychology but actually I’m making a really good opening choice here. Sal was a very careful, solid player so a provocative opening is perfect – he wouldn’t try to punish it outright.  So the text, although seemingly way out there, actually carries very little risk.

8. Re1 [5] 8. Bg5!? is interesting here. Then, 8…c5 9. a5! b5 10. dxc5! is strong for white.

8… Bb7 It’s humorous that Sal himself liked to play Modern Defense structures as black, and here I am not knowing that and blithely trotting it out. Nevertheless, I get a good game.

9. Bf1 9. Bc4 is certainly more active.

9… Nbd7 10. h3 Again, 10. Bc4 is more active. White is playing too slowly and black has no problems now.

10… e5 [37] 11. dxe5 dxe5 12. Bc4 Nc5! [43] A nice shot. It is white who has to be careful now.

matera2.png

13. Qxd8 Raxd8 14. Bg5 [41] Rd6 15. Nxe5? A major miscue. 15. Bxf6! Bxf6 16. b4 Ne6 17. b5! a5 18. Bd5! is a very nice way to maintain the balance.

15… Nfxe4 [53] As so often happens, the sudden opening of the game just gives black too much activity. White is simply losing control of the position.

16. Nxe4 Nxe4 17. Bf4 Rd4 [58]18. Ba2 [62]

 

matera3.png

If a good player hands his head on a silver platter, you have to take it.

18…Nc5?? [73] You don’t need a computer to see that the obvious 18… Nxf2! is completely winning. For example, 19. Be3 (19. Bg3 Ne4 20. c3 Rd2 wins with no problems) 19… Nxh3+! 20. gxh3 Bxe5 and white is dead lost. It’s impossible to say why I would think for 15 minutes and then avoid this easy line. A case of seeing ghosts? Continuing on a bit, 21. Bxd4 Bxd4+ 22. Kf1 Bxb2 23. Rad1 Bc6 24. Re7 Bxa4 25. Rxc7 Be5 and black mops up.

19. Bg5 Ne4 20. Bf4 Nc5?? [79] Naturally black passes up 20…Nxf2 winning once again. It’s not often that a player can miss two clear wins in the opening, but I did it. Matera escapes.

21. Bg5 Ne4 22. Bf4

1/2-1/2

 

A good example of a huge tactical blind spot changing the normal outcome of the game.

 

One more from the Atlantic Congress ’77 which I am guessing took place in New York City, although I did not record which hotel.

Atlantic Congress

04/17/1977

Mark Ginsburg (2157) – Roberto Kaimo (2293)

Sicilian Dragon, Yugoslav Attack

1. e4 c5 2. Nf3 Nc6 3. Nc3 d6 4. d4 cxd4 5. Nxd4 g6 6. Be3 Bg7 7. Qd2 Bd7 8. Bc4 Nf6 9. f3 a6?

In some openings, black can afford avant-garde experimentation. The Dragon is not one of them. The text loses an entire tempo.

10. O-O-O O-O 11. h4 Qa5 12. h5?! A little too gung ho. Now black has an amazing resource.

12…Rfc8? Which he misses! 12…Nxh5! leads to incredible positions. For example, 13. g4 Ng3 14. Rh3 Qb4!!

kaimo_var.png

Position after 14…Qb4!! (Analysis). This is really an amazing resource that I don’t think I’ve seen in other Dragon games. Play might continue 15. Bb3 Nxd4 16. Bxd4 Bxd4 17. Qxd4 Qxc3!! 18. bxc3 Ne2+ 19. Kb2 Nxd4 20. cxd4 h5! 21. Rh4 hxg4 22. Rdh1 Kg7 and black is fine!

13. hxg6 hxg6 14. Bb3 Ne5 15. Bh6 Bh8 This position is a good tactical quiz situation.

kaimo2.png

16. Bg5? White already had a win with the elegant quiz solution shot 16. Nf5! Qd8 17. Qg5 Rc5 18. Qh4 Bxf5 19. exf5 Qc7 20. Bf8!! Kxf8 21. Qxh8+ Ng8 22. Rh7 with total devastation. The move 20. Bf8!! is an attacking motif that every white Yugoslav Attack player should know – a classic clearance theme.

16… Bg7 17. Kb1 17. f4! Nc4 18. Qd3! b5 19. Bxf6! Bxf6 20. Nd5 is more to the point, with a huge edge.

17… Nc4 18. Bxc4 Rxc4 19. Nb3 Qc7? A grotesque blunder, walking into white’s next move and immediately losing. He had to try 19…Qd8.

20. e5! Nh5 21. Nd5 Qb8 22. Nb6 Be6 23. Nxc4 Bxc4 24. Bxe7 dxe5 25. Qg5 Qe8 26. Rxh5 gxh5 27. Bf6 Qf8 28. Rh1 Bxb3 29. axb3 Kh7 30. Qxh5+ Bh6 31. Bg5 1-0

What a massacre! It was not a good day for the Filipino NM. I don’t know what happened to Kaimo; I lost track of where he went in the 80s and beyond.
