The Fabulous 10s: Weirdness in St Louis (US Championship Round 2)

May 15, 2010

Round 2 Jitters

The official St Louis chess club web page says (in a caption of a photo of Kraai wearing an old-timey hat),

“GM Jesse Kraai played the higher-rated GM Varuzhan Akobian to a draw in round two.”  As a good citizen, I wrote it so they could correct it.

Weirdly, Kraai missed a good chance to resist at the very end!

Check it out:

[Round “2”]
[White “Akobian, Varuzhan”]
[Black “Kraai, Jesse”]
[Result “1-0”]

1. d4 Nf6 2. c4 e6 3. Nf3 c5 Why on earth would Kraai play a Benoni, an opening antithetical to his style?  Just a rhetorical question.  Look at the problems Akobian had with solid Slav’s in the World Team! However, it worked out well for black up to a point given white’s bizarre moves… let’s see it….

4. d5 exd5 5. cxd5 d6 6. Nc3 g6 7. g3 Bg7 8. Bg2 O-O 9. O-O Re8 10. Nd2 a6 11. a4 Nbd7 12. Nc4 Ne5 13. Na3 Bd7 14. Bf4 Nh5 15. Bxe5?! Chess is not so easy.  This should offer nothing.

15…Bxe5 16. Nc4 b5 16…Nf6 is fine for black.  Nothing wrong with the text move.

17. Nxe5 Rxe5 18. e4 Re8 19. Re1 Nf6 I think most routine Benoni players would immediately go for 19…b4! 20. Nb1 f5! 21. Nd2 Nf6! which is completely fine for black.   We should ask Vugar Gashimov what he’d do.

20. Qd2 Qb6?! 20…Ng4! is strong.  After 21. f4 Qb6! black is in no way worse.  However, both players keep playing second-rate moves and a strange roller-coaster ensues.

21. a5 Qd8 22. f4 b4 23. Nd1 Qb8 24. Nf2 Ra7 25. h3? Too slow.  25. Re3!

25…Bc8 26. Re3 26. Nd3!

26…Rae7 27. Rae1 Bb7 27…Nd7!

28. b3 Qd8 29. Kh2 29. e5! and take back on e5 with a rook is quite good for white.

29…Qa8 30. Qb2? 30. e5! is crushing.  It’s very unusual for Akobian to make so many second-rate moves in one game.

30….Nxd5! 31. Ng4 Nxe3???

31…Nc3! and quite amazingly white is held to a small plus after 32. Nf6+ Kf8 33. Nxe8 Qxe8.  For example, 34. Qd2 Qd8 35. e5 Bxg2 36. exd6 Rxe3 37. Qxe3 Qxd6! (37….Bc6?? 38. Qxc5!) and white will have to work hard.

To account for this blunder, Black said he was bothered by his premature draw in round 1.  It’s a long tournament!

32. Nh6+ 1-0

Deathly Hex Hat - must burn it

The hat looks like a Greg Shahade Porkpie special. It’s gotta go. 🙂   I suggest the Lucky Pen (Fedorowicz won the NY Open once with a Lucky Pen!) instead.  It will get Kraai on a lengthy winning streak.

One More Game from Round 2

Further chaos on a higher board…

[Round “2.1”]

[White “Nakamura, Hikaru”]
[Black “Hess, Robert L”]

1. Nf3 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qc2 c5 5. a3 Bxc3 6. Qxc3 O-O 7. b4 d6 8. Bb2
b6 9. g3 Bb7 10. Bg2 Nbd7 11. O-O Rc8 12. d3 Rc7?!
Gearing up to a faulty idea.

Example better line: 12… h6 13. e4 Qe7 14. Rfe1 Rfe8 15. b5 Ra8 16. a4 a5! and it’s OK for black.

13. e4 Qa8 14. Qd2 Rfc8 15. Nh4 b5? This doesn’t work at all.   American juniors almost always have a very tough thing doing nothing in particular.   And, among modern GMs, active Walter Browne lost a lot of games lashing out like this.

16. cxb5 c4 17. dxc4 Bxe4 18. f3 Bb7 19. Rfc1(?!) Easily winning was 19. Qxd6 Rxc4 20. Rf2 Bd5 21. Rd1 and white dominates.
19… Rxc4 20. Rxc4 Rxc4 21. Bf1 Rc8 22. Qxd6 h6
22… Bxf3 looks like a better try.  Now white is totally winning again, but the game is not free of further adventures – see the weird reciprocal blunder on move 33.

23. Rc1 Rxc1 24. Bxc1 g5 25. Ng2 Bxf3 26. Be3 Nb6 27. Bd4 Qd5 28. Qxd5 Nfxd5 29. Ne1 Bd1 30. Nd3 f6 31. Nb2 Bb3 32. Bg2 Kf7 33. Kf2? A serious lapse that is answered by a blunder in return.  Crushing was 33. Bxd5! with the study-like point:  33… exd5 34. a4! Nxa4 35. Bxa7! and wins, very nice!

33… e5?? A really bad blunder.  33… Nc8!  and black can hope for a draw.  For example, 34. a4 Nxb4 35. Bb7 Nd6 36. Bf3 Nc8 37. Bh5+ Kg7 38. a5 Nd5 39. Be8 Nc7 40. Bd7 Nd6 41. Bxa7 Ndxb5 42. Bb8 Bd5 and white has a tiny edge.

34. Bxd5+ Bxd5 35. Bxb6 axb6 36. Na4 f5 37. Nxb6 Ke6 38. a4 If you are curious, yes, 38. Nxd5 wins too.

38…f4 39. a5 Bh1 40. Kg1 Bf3 41. a6 e4 42. Nc4 e3 43. b6 1-0

Let’s See One More

Moving back to a lower board, more jitters!

[Event “2010 U.S. Championship”]
[Site “Saint Louis”]
[Round “2.8”]

[White “Bhat, Vinay S”]
[Black “Kudrin, Sergey”]

[Result “0-1”]
[ECO “D89”]

This game featured some incredible and very difficult to find missed opportunities for white behind the scenes.
1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Bc4 c5 8.
Ne2 O-O 9. O-O Nc6 10. Be3 Bg4 11. f3 Na5 12. Bd3 cxd4 13. cxd4 Be6 14. d5 Bxa1
15. Qxa1 f6 16. Bh6 Re8 17. Qd4 Bd7 18. e5
Not a very impressive line, white is soon put in the position of having to find only moves to equalize.

Qb6 19. Qxb6 axb6 20. e6 Ba4 21. Nc3
b5 22. Nxb5?
The first miss.  The brilliant 22. d6!! exd6 23. Re1!  establishes enough domination to hold the balance.  For example, 22…Nc6 (23… Nc4 24. Nd5 f5 25. f4 Kh8 26. Nf6 Nb2 27. Bf1 Rec8 28. a3 b4 29. axb4 Nc4 30. Bd3 Bb5 31. e7 d5 32. Nxd5 Be8) 24. Nd5 f5 25. Bf4 Ne5 26. Bxe5 dxe5 27. Rxe5 Kg7 28. Nc7 and draws.  The maximum coordination established by 22. d6!! is truly remarkable.

22… Red8 23. Nc3 Bc6 24. Be4 Be8 25. Rb1 Rac8 26. Bd2 Nc4 27. Be1 f5? A serious blunder!

27…Nd6 leaves black better.   I can only guess black didn’t see white’s possible reaction.

A Missed Miracle

28. Bd3? Oh no!  White misses a truly incredible shot.   But it takes deep calculation and a keen sense of adventure to take the plunge on it…. do you see it?

It’s 28. Rxb7!! fxe4 29. fxe4 and feast your eyes on this domination!   White is a full rook down… well he has some pawns…. but here’s the kicker – he’s not worse!

First of all, the lame 29…Kf8? loses to  the nice “carom billiards shot” 30. Bh4.
Secondly, 29… g5 30. Rxe7 Bg6 31. Bf2 Re8 32. Rd7 Ne5 33. Bd4 Rxc3 34. Bxe5 is fine for white too. In no line is white worse.  But it was hard to see! The connected pawns set up a mighty force giving plenty of compensation for the oodles of lost material.  It’s really unusual to see how helpless black’s forces are.

28… Ne3! And white loses prosaically.  Too bad!

29. Rxb7 Nxd5 30. Nxd5 Rxd5 31. Be2 Re5 32. Kf1 Rxe6 33. Rb4 Bf7 34. a4 Rc2 35. Bd3 Rc1 36. Be2 Re5 37. Rd4 Be6 38. Kf2 Rc2 39. Rd2 Rxd2 40. Bxd2 Rd5 41. Be3 Kf8 42. Bb6 Rd2 43. Ke1 Rc2 44. f4 Bc4 45. Bf3 e6 46. g3 Rxh2 47. Bf2 Bd5 48. Bd1 Ke7 49. a5 Bb7 50. Kf1 Bg2+ 51. Ke2 Rh1 52. Kd2 Bb7 53. Bb6 h6 54. Be2 Ra1 55. Ke3 Ra3+ 56. Kd4 Rxg3 57. a6 Bxa6 58. Bxa6 h5 59.

22. Bg3 Bxg3 23. hxg3 Qg5 24. Qf2 Nh5(?!)

Very strong is the powerful and aesthetic central shot 24… Ne4!!.  White can only grovel to equalize after that move.  25. Nxe4 (I cannot resist showing a mating line after 25. Bxe4 fxe4 26. f4? Qf5 27. Ne2 Nf6 28. Qe1 Ng4 29. Qd2 Qh5 30. Rfe1 Qh2+ 31. Kf1 c5 32. Rc1 cxd4 33. exd4 e3 34. Qc3 g5! 35. Rc2 gxf4 36. gxf4 dxc4 37. bxc4 e5!! 38. dxe5 Qh1+ and already the computer sees a long forced mate, here it is for enjoyment:  39. Ng1 Rxf4+ 40. Ke2 Rd8 41. e6+ Kg8 42. Qd3 Qxg2+ 43. Kd1 Rxd3+ 44. Kc1 Qd2+ 45. Rxd2 exd2+ 46. Kd1 Nf2+ 47. Kc2 Rxc4+ 48. Kb2 Rb4+ 49. Kc2 dxe1=N+ 50. Kc1 Rd1mate!)   Returning to the better 25. Nxe4, 25… dxe4 26. Be2 Nf6 27. f4 Qg6 28. c5 equal.

The game move is actually not bad and white immediately blunders.

25. g4? What’s this? Shabba goes a little bonkers, losing a pawn for nothing.  25. Ne2 was necessary.

25…fxg4 26. f4 Qf6?
Any computer will tell you the “carom shot” 26… Qe7 27. g3 Qb4! is very strong with a distinct edge to black.

27. g3 c5? 28. cxd5 cxd4 29. Ne4! And black has self-destructed.  Too bad!

The Fabulous 00s: The Resurgence of the 1890s

June 24, 2009

Behold, Once Again, the Two Knights

GM Nakamura scored a key win over GM Friedel in the last round of the US Championship 2009 with a two knights sideline opening fresh from the 1890s.  Curiously, GM Friedel in his notes in Chess Life Online did not mention the most active way to play.  He played a “safe” “solid” way but that way was passive, white kept an extra pawn, and won easily. Maybe he hasn’t looked it up yet!  Postscript Sunday June 28: I am not sure what’s in the water, but now the game has appeared in print annotated by both parties, and in neither case black’s best 8th move was mentioned.  Presumably the annotators have had time to reflect and present the readers with the right move, so I don’t know what’s going on.

Here is how the key game started.

Nakamura-Friedel US Championship 2009

1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 There is a school of thought that, for safety’s sake, or even more precisely, for logic’s sake,  follow what Karpov does.  GM Short told me that if GM Karpov plays 3…Bc5 here, it is likely to be best.  Logical!  Logic in the opening by proxy!  But when Karpov starts dancing with his king on f8 in Caro’s, well, watch out.

4. Ng5 d5 5. exd5 Na5 Known to be bad is 5…Nxd5? 6. d4!.  Not so clear is the schoolboy favorite, 6. Nxf7, the Fried Liver Attack.  I think d4! first then taking on f7 is the way theory recommends.

6. Bb5+ c6 7. dxc6 bxc6 Black has a sidelined knight on a5 and a pawn minus, but a lead in development and prospects for gaining more time by hitting the knight on g5. This position has been seen a lot, and white’s next is no novelty at all.

8. Bd3 Not new at all. In fact, quite old.  And also played in a major league game in 2008.  Both old and new!   A double-headed monster that needs to be … well….. looked at.  GM Short told me that he faced this in blitz vs GM Morozevich, “reaching a good game but then losing.”  In a curious “double”, Nakamura once scored easily with 1. c4 Nf6 2. Nc3 e6 3. e4 d5 4. e5 d4 5. exf6 dxc3 6. bxc3 Qxf6 7. Bd3!? vs an Argentinian GM and ex-world junior champion Pablo Zarnicki, HB Global Challenge Minnesota 2005. At this point Friedel writes in CLO, “I vaguely recalled it, but of course had no clue what to do.  I  decided to go  “solid” again with Be7 and 0-0.  Better might have been an earlier h6 followed by Nd5 and f5-e4 with counterplay.”  Needless to say, 8…Be7? was a huge lemon and Nakamura had no trouble whatsoever scoring the full point in short order.  Although on ICC there were some funny moments when GM Kraai (perhaps inebriated, that would be my guess) started scream/kibitzing after Friedel’s unsound sac on d3 that “the panda’s junk was all over the board”  – it took quite a bit of deduction to figure out he was referring to Friedel as the Panda.  Nevertheless, the junk (I think) stayed back in its package as Nakamura just pocketed the material and then trapped the queen. The most ‘objectionable’ thing is that Chess Life Online readers come away with nothing at this key juncture.  But it’s more or less free… the peanuts and monkeys syndrome?

Instead of solid, we need fast!  More precisely, there’s a faster way for black to ‘get there’ in Friedel’s counterplay notion.  Better is what Emanuel Lasker found in 1892 versus Henry Bird!  (And repeated in recent memory by Erwin L’Ami).  The right move is 8…Ng4! When facing something strange, do something “strange” – but the move is really quite logical!

Postscript Sunday June 28: I received New in Chess magazine 2009/4 in the mail (late, I know; I go with the chessplayer’s stingy surface mail option) – and I was very surprised to see Nakamura annotate this game and pass by 8…Be7 without comment. His secrets after 8…Ng4 go unmentioned. On purpose?  The readers come away with absolutely no information.

This is the way to get the Panda's Junk on the Board

This is the way to get the Panda's Junk on the Board

Bird-Lasker Newcastle-on-Tyne 1892 (have you heard of that event??!) saw 8…Ng4 9. Nf3 f5! The correct followup. After 10. h3 e4! we had true chaos on board, and Lasker outplayed Bird subsequently. But let’s not trust a game from 1892.  We need to look at this try more carefully. The most interesting recent game, between two young Dutch lions, saw in

Stellwagen-L’Ami, Maastricht 2008, 8…Ng4! 9. Ne4!? f5! Always this!  Black needs this.  10. Be2 h5! with absolute chaos once again! 11. h3 fxe4 12. hxg4 Bc5! with madness and a definite black initiative.  The kind one is supposed to get with the …Na5 gambit! I am pretty sure Friedel might have looked this up by now.  Or maybe not?  Anyway it looks like 8…Ng4 is the way to go, and I look forward to Nakamura being challenged with this!  (but maybe he’ll switch away now that the surprise is gone).  In the meantime, can readers switch on their collective Rybkas and give me best play and evaluation after this?  Merci et adieu.

A Weird “Double”

From the Copper State International, Altounian-Barcenilla (copied from Chess Life Online, annotations by GM Alex Yermolinsky unless italicized by MG)

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5

This old line, known as the Fried Liver Attack, is making an unexpected comeback these days. I faced it against David Pruess in 2007, and there was a recent Nakamura-Friedel U.S. Championship game. I have mixed feelings about it. On the one hand, modern computer analysis can re-evaluate some positions from the defensive point of view. On the other hand, it’s hard to believe that generations of chess players were wrong in their assessment of resulting positions as good for Black

4…d5 5.exd5 Nd4

Altounian was quite surprised by this little known sideline. 5…Na5 6.Bb5+ c6 7.dxc6 bxc6 and the old move 8.Be2 is being superseded by(8.Qf3 Pruess; or 8.Bd3 Nakamura.)

6.c3 b5 7.Bd3!? Shadows of Hikaru… 7.Bf1 Nxd5 transposes to well-known theoretical lines, such as 8.Ne4 Ne6 9.Bxb5+ Bd7 10.Bxd7+ Qxd7; Another chapter is 7.cxd4 bxc4 and now either 8.Qa4+ (or 8.dxe5 Qxd5 9.exf6 Qxg5 10.Qf3 Rb8) 8…Qd7 9.Qxc4 Qxd5 In both cases, the computer gives White a big plus for whatever that’s worth.

7…Nxd5 The alternative 7…Bf5 was seen in Morozevich-Timman, 1996 where after 8.Bxf5 Nxf5 9.Qf3 Nh4 (9…g6!?) 10.Qh3 Ng6? the young Alexander missed the crushing shot (better was 10…Nxd5 11.Qxh4 Be7 12.d4 Nf4 13.Bxf4 exf4 with some play for a pawn; but not 10…Qxd5 11.Qxh4 Qxg2 12.Rf1 h6 13.d3 and White keeps the extra piece.) 11.Nxf7 and instead went on to lose the game.

8.Nxf7 8.cxd4 Qxg5 9.Bxb5+ Kd8 10.Qf3 is another transposition to the 7.Bf1 theoretical line.

8…Kxf7 9.cxd4 Nf4 Should further analysis prove White’s advantage in the way the game went, it might be worth looking at the crazy line 9…Nf6 10.Bxb5 exd4!? (I don’t think Black has anything going after 10…Qxd4 11.Nc3 Bc5 12.Qe2 Be6 13.d3) 11.Bc4+ Kg6 12.0-0 Bd6 13.Qc2+ Bf5 14.Bd3 Qd7 and the hyperactive black king may turn out to be a real asset in the endgame. 10.Be4after10.be4barcalt.jpg

10…Qxd4!

Barcenilla must get credit for energetic play. Weaker was 10…Rb8 11.dxe5 Nd3+ 12.Kf1 and Black cannot maintain the knight on d3 because of the exposed position of his own king (checks from b3, f3 or h5 are coming).

11.d3 White was not advised to take the gift, 11.Bxa8? Nd3+ 12.Ke2 Bg4+ 13.Bf3 (13.f3 Nf4+ 14.Ke1 Nxg2+ 15.Ke2 Nf4+ 16.Ke1 Be7 bringing more pieces into the fray.) 13…Nf4+ 14.Kf1 Bxf3 15.Qxf3 Qc4+ 16.Ke1 Qxc1+ 17.Qd1 Nxg2+ 18.Ke2 Nf4+ 19.Ke1 Nd3+ 20.Ke2 Qc4 and Black’s attack just doesn’t seem to let up.; A more reasonable possibility, along with the text move, was 11.Nc3 Nd3+ 12.Bxd3 Qxd3 13.Qb3+ Be6 14.Qxb5 although the black bishop pair would provide ample compensation even after the queens are swapped.

11…Bb4+ 12.Nc3 Bxc3+ 13.bxc3 Qxc3+ 14.Bd2 Nxd3+ 15.Kf1

15.Ke2 Nf4+ 16.Bxf4 exf4 17.Bxa8 Be6 clearly favors Black.

15…Qc4 16.Qe2? A serious mistake. White had to play 16.Qb3 to get the queens off. There are various ways for Black to proceed, but I can’t see a fully satisfactory continuation.

In fact White should win after 16. Qb3!.  This was the key moment.  If Altounian had won the game, he would have been in great shape to make a GM norm.  As it happened, the victor in this game did make a norm!  Such is chess.

16…Rd8!! after16...rd8.jpg Absolutely brilliant!

17.Bxa8 Bf5 18.Bb7 18.Bf3 e4 19.Bg4 Bxg4 20.Qxg4 Ne5+ 21.Qe2 Rxd2 wins for Black.

18…Qd4 19.Rd1 Nb2!? 19…Nf4 20.Qe3 Qc4+ 21.Kg1 Ne2+ 22.Kf1 Nf4+ was enough for a draw, but Rogelio was after the jackpot.

20.Qh5+ Ke6 21.Ke1?? Levon could keep on fighting after 21.Rc1 Qxd2 22.Rc6+ Rd6 23.h3

21…Nd3+ White gets mated on the next move.

0-1 A very sad finish for Levon.  This was a tough tournament with a fast time control and many strong opponents.

The Fabulous 00s: Some Chess Theory from the Tulsa US Championship Qualifier

April 18, 2008

The March 2008 Tulsa, Oklahoma US Championship Qualifier had some interesting games from the perspective of chess theory. Let’s see some of these perpetual time pressure games (G/90 + 30 sec increment). Endings suffered, and opening familiarity rose to the foreground. See this background post for some Tulsa “glamor shots.”

GM Alex Yermolinksy – NM Movses Movsisyan, Round 2. Gruenfeld Defense.

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Nf3 c5 8.Be3 cxd4 Here, 8…Qa5 and 8…O-O are the most popular. Strangely, black plays a burst of natural but rare moves and emerges with a good game!

9.cxd4 Bg4 9…Qa5+ 10. Qd2 Qxd2+ was a quick draw in Groszpeter-Farago, Bibinje 2006, but white has a small edge after 11. Kxd2 Nc6 12. Rb1 (12. Rc1 was played).

10.Be2 Nc6 11.d5 (What else?) 11…Ne5 12.Nxe5 Bxe2 13.Qxe2 Bxe5

Position after 13…Bxe5.

14.Rd1?! Previously, the lame 14. Qb5+? Qd7 led nowhere in Gorshkov-Zilberstein, Sverdlovsk 1979, and drawn in 30 moves. However, 14. Rc1! looks more useful than the artificial text move. After all, 14. Rc1! Qa5+ 15. Qd2 Qxd2+ 16. Kxd2 with f2-f4 coming is a solid ending edge for white.

14…Qa5+ 15.Bd2 Qa4! With simple moves, black has achieved a good game against the experienced grandmaster. Note that Yermo provided several good wins of his vs. the Gruenfeld in his book “The Road to Chess Improvement.” This indicates that black’s particular Gruenfeld choice in this game warrants further study. Well, maybe not, since white did have the stronger 14. Rc1! in the game.

16.Bh6 Qb4+ After 16…Rc8 17. O-O Rc2, black has full equality. For example, 18. Qd3 Rxa2 19. Rc1 Ra3 20. Qe2 Ra2 21. Qf3 Ra3 is a perpetual attack on the queen and draw.

17.Kf1 Rc8 18.g3 Rc4 19.Re1 Bc3 19…Qa4! eyeing c2 is strong. Then, 20. Kg2 f6 makes an escape hatch for black’s king and once again he is happy.

20.Rc1 Rxe4?? Black ruins everything with a dreadful tactical oversight. 20…b5 was fine. For example, 21. f3 Be5 22. Kf2 Kd7! with equality.

21.Qc2 Rc4 22.Bg7! Oops. Undoubtedly overlooked by black. The rest of the game is technique.

22…Bxg7 23.Qxc4 Qxc4 24.Rxc4 Kd7 25.f4 b5 26.Rc6 Rb8 27.Ke2 b4 28.Ra6 Rb7 29.Rb1 Bc3 30.Kd3 Rc7 31.Rc1 Rc5 32.Rxa7+ Kd6 33.Ke2 33. a3 is a simple win. 33…Rxd5+ 34. Kc4! Rd4+ 35. Kb3 Rd3 36. axb4! Bd4+ 37. Kc4! does the trick. The text is fine too. White will win this.

33…Rxd5 34.Rd1 Rxd1 35.Kxd1 Bd4 36.Rb7 Bc5 37.Ke2 Kc6 38.Rb8 Kd5 39.Kd3 e5 40.fxe5 Kxe5 41.Rb7 Ke6 42.g4 Bd6 43.h3 h6 44.Ke4 f5+ 45.gxf5 gxf5+ 46.Kf3 Be7 47.Rb8 Kf6 48.Rg8 Bd6 49.h4! Iron-clad. 49…Kf7 50.Rg2 Be7 51.h5 Bg5 52.Rc2 Ke6 53.Rc6 Kd5 54.Rb6 Kc5 55.Rg6 Bd2 56.Ke2 Bc1 57.Rf6 Kb5 58.Rxf5 Ka4 59.Kd3 Bb2 60.Kc4 Bc3 61.Rd5 Ka3 62.Rd6 Kxa2 63.Rxh6 Bd2 64.Rd6 Bc3 65.h6 Kb2 66.h7 Kc2 67.Rh6 Bh8 68.Kxb4 Kd3 69.Re6 1-0

IM Blas Lugo – GM Jesse Kraai Round 4, French Exchange


1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 dxe4!? 5.Nxe4 Be7
A favorite treatment of GM Evgeny Bareev. This is not as quiet as it appears since the kings wind up on opposite sides often. It has the advantage of avoiding many long mainline theory variations.

6.Bxf6 Bxf6 7.Nf3 Nd7

Position after 7….Nd7. Decision Time.

8.Qd2 Maybe it’s just me, but I think a planned Bishop placement on d3 warrants a queen on e2 more than a queen on d2. For example, 8. Bd3 O-O 9. Qe2 c5!? 10. O-O-O cxd4 11. h4!? with ultra sharp play (eventually drawn) in Sutovsky-Ivanchuk, Moscow 2002. Both this plan and the text have been seen in dozens of games, of course.

8…O-O 9.O-O-O Be7 10.Bd3 b6 11.Kb1 The primitive 11. h4 turned out to be too slow in Suetin-Bareev, Hastings 1991, and black won after 11…Bb7 12 Kb1 Nf6. To give a counter-example, White won after 11. h4 Bb7 12. c3!? Nf6 13. Neg5 Bxf3 14. gxf3, but this position is equal after 14…Qd5. Black played 14…Kh8?! and lost in Topalov-Dreev, Linares 1995. The text move, on the other hand, also doesn’t promise much – only 3 draws in Chessbase’s BigBase. A more dangerous try is 11. Neg5!? which hopes for 11…h6? — after 11. Neg5 h6?, white scored +4 =0 -0 in ChessBase!

Position after 11. Neg5!? (Analysis). Black has to be careful.

But there’s a curiosity here: in Volokitin-P.H. Nielsen, Germany 2004, the game went 11. Neg5 h6 12. Bh7+ Kh8 13. Be4 which at first glance looks good for white. However, upon reflection doesn’t it look like black missed 13…hxg5 14. Bxa8 g4! and the threat of Be7-g5 wins material? We will come back to this. In the game, black played 13…Bxg5 14. Nxg5 Rb8 and lost. However, he was doing OK after 15. Nf3 Nf6 16. Bc6 Qd6 17. Ne5 Ng4! 18. Nxg4 Qc6 – he only lost due to later middlegame miscues. The truth about 13…hxg5? is revealed in another example, J. Polgar – F. Berkes, Budapest 2003, white introduced an incredible gambit: 12. Bh7+ Kh8 13. Be4 hxg5? 14. g4!! (not the greedy 14. Bxa8?) and now black faces complex problems. White stops black from playing g5-g4 and prepares to open the h-file. In the game, black lost after 14…Rb8 15. h4 g6 16. hxg5+ Kg7 17. Qf4 and white crashed through. The question is, can black live after 14. g4? Let’s take a look. First of all, 14….Ba6 15. h4! gxh4 16. g5! is crushing. For example, 16…Kg8 17. Rxh4 f5 (What else?) 18. Bc6 Rc8 19. Rdh1 Kf7 20. d5! and wins. Let’s go back to Berkes’s choice, 14…Rb8. 15. h4 and first we see that 15…gxh4? is bad: 16. g5 g6 17. Rxh4+ Kg7 18. Rdh1 Rg8 19. Rh7+ Kf8 20. Qf4! and wins.

So we go to Berkes choice, 15…g6 16. hxg5+ Kg7 17. Qf4. This is critical. We first notice that 17…Ba6 is crushed by a typical Judit Polgar brute-force tactic 18. Rh7+!! Kxh7 19. Qh2+ Kg8 20. Rh1 Bxg5+ 21. Nxg5 Qxg5+ 22. f4! and wins. We also notice that Berkes’s choice, 17…Bb7?, was crushed by the same tactic.

what about 17…Rh8!? – trying to defend on the h-file. There follows 18. Rxh8 Qxh8 (forced) 19. Ne5! and now black cannot take: 19…Nxe5? 20. Qxe5+ Kg8 21. Qxc7 Bxg5+ 22. Kb1 and the rook on b8 is trapped; white wins. And after 19…Qe8 20. Rh1! the lethal threat of 21. Nxf7! is introduced. Black still cannot take on e5 and hence is lost.

Going back to the beginning, 11. Neg5!? is best met by 11…Bxg5! and now 12. Qxg5 Qxg5+ 13. Nxg5 Nf6 is dead equal. Or, 12. Nxg5 Nf6 and black is OK and even won in B. Lopez-Kraai, San Diego 2004. That game continued 13. Qf4 Bb7 14. Rhe1 Qd6!? and here white disdained an equal ending after 15. Qxd6, opting for 15. Qh4 h6 16. Nf3 (16. Ne4! equal) Bxf3 17. gxf3 Nd5 18. Re4, eventually getting into trouble with the weak d4 pawn. White tried 13. h4!? in Sax-Dizdar, Celje 2003, and black reacted suspiciously with 13…c5?! 14. dxc5 Qd5 15. Kb1? Qxc5 equal. But white missed 15. Qf4!! Qxa2 16. Nxh7! Nxh7 17. Qe4 Nf6 18. Qxa8 Qa1+ 19. Kd2 Qxb2 20. Qxa7 and white keeps a small plus. Stronger is 13. h4 Bb7! and black is fine.

11…Bb7 12.Qf4 c5 In Sindik-Dizdar, Pula 1993, black introduced an idea similar to the game a little earlier: 12…Qb8!? 13. Qg3 c5! with good play. White can improve with 13. Ne5! c5 14. Bb5! Nf6 with sharp play after 15. Nxf6+ Bxf6 16. Rhe1 and now the Korchnoi pawn grab 16…Bxg2!?

13.dxc5 Qb8! Gambits in opposite-castled king positions are effective even in the ending! This is particularly true in the “perpetual time pressure” time control of G/90+30 sec. This motif, although it has been seen before, is ingenious and disconcerting for white. There is no more attack and white has to switch gears (notoriously difficult) to a defensive up-a-pawn but under pressure mode.

Position after 13….Qb8! – A gambit to reach an ending!

14.Qxb8 Raxb8 15.cxb6 Nxb6 16.b3? Correct is the solid but not particularly easy to find 16. Ned2! and then a defensive hunkering down. This would not create the glaring c3 weakness in the game. White would then have enough counter-chances.

16…Na4! Very unpleasant to meet in this time control. White probably overlooked this. The c3 square is now home for black’s knight.

17.Rde1 Bxe4 18.Bxe4 Nc3+ 19.Kb2 Bf6 This position is terrible for white.

20.Bd3 Ne4 21.Kb1 Nxf2 22.Rhf1 Nxd3 23.cxd3 Rfd8 24.Re3 a5 25.Ne5 Rd5? Correct is 25…Bxe5 26. Rxe5 a4! and black is on top. For example, 27. Kc2 axb3+ 28. axb3 Ra8 29. Kc3 Ra2 with a huge initiative.

26.Nc6 Rb7 27.Rg3 Kf8 28.Rf4! White is doing the right things now to get back in the game.

28...Be5 29.Nxe5 Rxe5 30.Rc4 f5 31.Rf3? 31. Kc1!

31…Ke7 31…Re2! is strong. 32.Rf2 Rd7 33.Kc2 Red5 34.Rf3 Kf6 35.Kc3 g5 36.d4? 36. h4! to reduce the number of pawns.

36…f4 37.a3 Kf5 Now black is gaining control again with his monstrously active king.

38.Rc5? White had to wait with 38. Rf2. The pseudo-active text is crushed.

38…g4 39.Rf1 e5! White probably underestimated this.

40.Rxd5 Rxd5 41.dxe5 Rxe5 42.Kd2 h5 43.b4 axb4 44.axb4 h4 45.Rb1 f3 46.gxf3 gxf3 47.b5 Kg4! The key move. White is lost.

48.b6 f2 49.b7 Re8 50.Rb4+ Kh3 51.Rb3 Kg2 52.b8Q Rxb8 53.Rxb8 f1Q 54.Re8 0-1

In more Round 4 action:

GM John Fedorowicz – FM Michael Langer Modern Benoni

1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.Nf3 g6 7.Nd2 Nbd7 8.e4 Bg7 9.Be2 O-O 10.O-O Re8 11.a4 Ne5 12.Qc2 g5 13.Ra3 Fischer defeated the lame 13. Nf3?! Nxf3+ 14. Bxf3 h6 in Gligoric-Fischer, Palma de Mallorca 1970 Interzonal. White has equality here but Gligoric soon made a fatal tactical miscue. The text move is an idea of Petrosian’s; but will it “work” along the 3rd rank or get stuck?

Position after 13. Ra3. How useful will this rook be?

13…g4 14.Nd1 Ng6!? The very interesting 14…Nh5!? was seen in Antunac-Y. Gruenfeld, New York 1981, and black managed to win eventually. The game proceeded 15. Ne3 Nf4 16. Bd1 and black was very active. If 15. Re1 Nf4 16. Bf1 Neg6 and black is also OK and drew in 23 moves, Karolyi-Poloch, Leipzip 1984. The most active move, 15. f4!?, might be good for white but prior games misplayed both sides: 15…gxf3 16. Nxf3 Ng6?! 17. Ng5? (17. Bg5! with edge) and drawn eventually, Koualty-Renet Marseille 1988. Or 16…Nxf3+ 17. Bxf3 (17. Raxf3 is a white edge) 17…Be5?? 18. g3?? and white even lost in 40 moves, Nowak-Pokojowczyk Zielona Gora 1982. Black’s 17th move was complete bluff and white could win with the very nice 18. Bxh5 Qh4 19. Rg3+! (Ouch!) 19…Bxg3 20. Bxf7+ Kg7 21. hxg3 Qxe4 22. Bh6+!! Kxh6 23. Qc1+! Kg7 24. Qg5+ and now black must lose his queen with the sad 24…Qg6 – so it’s resignable.

Tentative Conclusion: 15. f4! is the best move after 14…Nh5!?

The natural move 14…Bd7!? is also very interesting. White gets in trouble after the lemon 15. Bb5? Bxb5 16. axb5 Qb6!. No edge for white is to be seen in this position. After the text move, black has enough counter-chances as well.

15.Ne3

Position after 15. Ne3.

15…Qe7?! 15…Nf4! is a good choice. Witness the nifty defusing tactic: 16. Bb5 Bd7! 17. Bxd7 (apparently gaining the monster square f5 for the knight) 17…Ne2+!! 18. Kh1 Qxd7 19. Nf5 Nd4! with equality. A very nice defensive motif. There is also 16. Bc4 and here is a crazy repetition draw line: 16. Bc4 Bd7 17. f3!? gxf3 18. Rxf3 Bh6 19. Kh1 Bg5 20. Rg3 N6h5 21. Rf3 Nf6 22. Rg3. Unforced, but you get the idea. Putting the queen opposite the white rook (soon to arrive on e1) will have nasty consequences in the game.

16.Bb5 Rd8 17.a5 Not much is accomplished by 17. f4 gxf3 18. Rxf3 a6 19. Bd3 Ne5 with equality.

17…Nf4 17…a6 is possible. If 18. Ba4 Nf4 19. Re1 with a small white edge.

18.Re1 h5 19.Qd1 h4? Again, the careful 19….a6 is good to include. For example, 20. Bf1 Re8 and all is well. More dangerous is 20. Ba4! Rb8 21. Bc2! with a latent attack in the works. The impulsive text is an example of going overboard in a Modern Benoni. Just because the opening is an active choice does not mean every single move has to be maximally active even at the cost of weakening.

20.Nf5! The punishment. Black’s king is too weak now.

20…Bxf5 21.exf5 Qf8 22.Ne4 N4xd5 23.Bg5 Note that 23. a6! is crushing.

23…Nxe4 24.Rxe4 Nf6 25.Bxf6 25. Re1 with the idea of Bxh4 would win easily also.

25…Bxf6 26.Rxg4+ Kh7 27.Qd5 Black is paralyzed.

27…Qe7 28.Re3 Qc7 29.Rxh4+ 29. Qe4 with the idea of 30. Rxh4+ was total butchery. The text also wins quickly.

29…Bxh4 30.f6 Kg6 31.Re7? 31. Bd3+ is a fast forced mate. 31…Kxf6 32. Qf5+ Kg7 33. Qh7+ Kf6 34. Qh6 mate. Accuracy is often a victim at this crazy time control (or maybe white was playing on black’s clock). Of course, the text wins easily as well.

31…Qxe7 32.fxe7 Bxe7 33.Bc4 Rf8 34.Qe4 Kf6 35.Qh4 Ke5 36.Qxe7 Kd4 37.Bf1 1-0

Let’s move on to a real barn burner between two strong Grandmasters.

Round 5. GM Goldin – GM Yermolinsky Slav Defense

1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.e3 Bf5 5.Nc3 e6 6.Nh4 Be4 7.f3 Bg6 8.Qb3 Qc7

Position after 8…Qc7. To 9. g4 or not to 9. g4.

9.Bd2 GM Vadim Milov, a connoisseur of opening theory, played 9. g4!? here and won after 9…Be7 10. g5!? Nfd7 (10…dxc4!) 11. Nxg6 hxg6 12. f4 f6? (12…dxc4!) 13. Bd2 with a big edge; Milov-Rogozenko, Istanbul 2000. If black had played the correct dxc4! on either move 10 or move 12, he would have had equal chances. Goldin’s natural move has also been seen.

9…Be7 10.Nxg6 Karpov got nowhere with 10. g3 Bh5! and drawn in 31 moves, Karpov-Bacrot Cannes 2000. 10. cxd5!? looks stronger. After 10…cxd5 11. Nxg6 hxg6 12. Bd3 Nc6 13. O-O-O, black missed the mirror move 13…O-O-O! and lapsed with 13…a6, going on to lose in Malakhov-Volkov, Sochi 2004.

10…hxg6

Position after 10…hxg6. A very critical moment. To cackle or not to cackle?

11.Rc1 This is an important moment. Van Wely was successful twice (vs. Volkov and Sokolov) with 11. O-O-O! here. For example, 11. O-O-O Nbd7 12. cxd5! Nxd5 13. Kb1 Nxc3+ 14. Bxc3 and white is clearly better (Van Wely-Sokolov, Amsterdam 2002, and 1-0, 55 moves. Or, 11. O-O-O a6 12. Kb1 dxc4 13. Bxc4 b5 14. Bd3 Rxh2 and here, 15. Ne4! is strong with white advantage (15. g4?! was played, but white won a long game anyway, Van Wely-Volkov, Panormo 2002, 1-0, 79). After 11. O-O-O, 11…dxc4!? looks critical. 12. Bxc4 b5 13. Be2!? a6 14. Kb1?! was Tregubov-Bareev, and black won a tough struggle, 0-1 40 moves, Venacu 2006. It’s easy to find improvements for white. First of all, in the game, 14. e4! is strong (14…Rxh2? 15. e5! with a big edge). Secondly, the more active 13. Bd3!? (with Nc3-e4 ideas) is a tricky try one move earlier. Black’s position is very dangerous after 13…Rxh2 14. Qc2!. Conclusion: 11. O-O-O! is strong!

11…Nbd7 12.cxd5 exd5 12…Nxd5! is fine for black. For example, 13. e4 Nxc3 14. bxc3 Bh4+! (the point!) and black is happy.

13.e4 13. g3 Bd6 got white nowhere in Chiburdanidze-Zhukova, Istanbul 2000, and drawn in 16 moves.

13…dxe4 14.fxe4 Rxh2 14….Rd8! is perfectly good for black. The text is OK too but chances are still balanced. We are now out of book and it’s …. about even.

15.Rxh2 Qxh2 16.Qxb7 The computer move 16. e5 is playable. One humorous line is 16…Nxe5!? 17. dxe5 Qxe5+ 18. Kd1 Rd8 19. Qxb7?? Qf4! and wins.

16…Rb8 17.Qxc6 Rxb2 18.Nb5 Qh4+ 19.Kd1 Qf2

Position after 19…Qf2. White falls on his own Claymore.

20.Qa8+?? A horrific blunder that loses on the spot. 20. Qc8+! is drawn. For example, 20…Bd8 21. Be2 Qg1+ 22. Be1 Qe3 (or 22…Nxe4 23. Nc7+ Ke7 24. Nd5+ with a perpetual check) 23. Rc2! (guarded by the queen!) Rb1+ 24. Rc1 Rb2 25. Rc2 with a repetition. White must have missed something very simple.

20…Bd8 21.Be2 Qg1 22.Be1 Qxg2 Oops. There is no 23. Rc2 defense because the white queen is on a8, not c8. So white could already resign.

23.Bd2 Qg1 24.Be1 Qe3 25.Rc8 25. Nc7+ Ke7 is just a spite check.

25…Qxe2+ 26.Kc1 White has seen enough and resigns before black can play 26…Rxb5. An unusual collapse on Goldin’s part.

0-1

Here’s an important last round game – the winner qualified for the US Championship (to be held also in Tulsa). Once again the Gruenfeld triumphed.

IM Salvijus Bercys – GM John Fedorowicz Round 7, Gruenfeld Defense

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Nf3 c5 8.Be3 Qa5 For 8…cxd4, see Yermolinsky-Movsisyan discussed above.

9.Qd2 O-O 10.Rc1 The most popular, but 10. Rb1 is a major alternative. Statistically, 10. Rb1 scores a little better.

10…Rd8 11.d5 e6 12.c4 Qxd2 13.Nxd2 b6 14.Be2 Na6 15.O-O GM Khenkin is a proponent of the weird 15. Nb1!?. After 15. Nb1 f5 16. f3 fxe4 17. fxe4 Bb2 18. Rd1 exd5 19. cxd5 Re8 the chances were balanced and the game was drawn in 24 moves, Khenkin-Gutman Bad Wiessee 2002.

15…Nb4 Still the mainline, we are following 18 games in ChessBase. Nevertheless, the position appears to promise zero for white so it’s a mystery why it has occurred so often.

16.a3 Na2 Black’s knight wanderings are actually very logical. White has proven nothing in practice starting from this point.

Position after 16…Na2. White has nothing.

17.Rc2 Nc3 18.Bd3 White plays a slightly less common move now. The most common move is the awkward looking 18. Bf3. However, black won after 18. Bf3 exd5 19. cxd5?? (19. exd5! Bf5 20. Rcc1 equal) 19…Ba6 20. Rfc1 Ne2+ 21. Bxe2 Bxe2 22. f3 Bd3 with an obvious advantage, R. Stone – Ilya Gurevich, Chicago 1992.

18…Ba6 19.Bg5 Some white players have preferred 19. Nb1? here, but it’s just a blunder after 19…exd5 20. Nxc3 d4 with a big black edge after 21. Nd5 dxe3 22. fxe3 Be5.

Position after 19. Bg5. Time for a surprise!

19…exd5!? TN I have not been able to locate this move, hence I am labeling it a Theoretical Novelty (TN). Previously seen was 19…Rd7!? and black has quite a good game. For example, 19…Rd7 20. Rfc1 h6 21. Bf4 exd5 22. Rxc3 Bxc3 23. Rxc3 g5 24. Bg3 dxc4 25. Nxc4 Rd4 26. Bf1 Rad8 27. f4?? Rxe4 and black went on to win, Tunik – Timofeev, St. Petersburg 2002. 27. f3! of course was correct with an equal game. The conclusion is that the entire line is harmless. White has to seek improvements earlier.

At this point, according to Monroi, black had spent 1 minute and 30 seconds executing all these moves! The sacrifice is made even more attractive by the fact black is not risking anything. His position is very solid after white grabs the exchange with the bishop pair and an extra pawn.

20.Bxd8 White, surprised, took 8 minutes on this and now had 1:02 remaining.

20…Rxd8 21.exd5 Nxd5 22.Re1 Nf4 23.Bf1? Passive. White only spent one minute on this clunker. 23. Be4! is clearly stronger. White is in no danger after 23…Ne6 24. Nf3 Bf6 25. g3. Or, 23…Nd3? 24. Bxd3 Rxd3 25. Re8+ and white is too active.

23…Ne6 24.Nb3 Weird. 24. Nf3 is more natural.

24…Bb7 25.a4?! White’s moves are all connected to a poor plan of queenside action. He could have still bailed out with 25. Rd2 and a likely draw.

25…a5 26.Ra2 Bc3 27.Rc1 Bb4 28.f3?! 28. Be2, guarding d1 and contemplating Rd1, looks better.

28…Bc6 29.Kf2 Kg7 30.Be2 Nd4 31.Nxd4 cxd4 32.Bd3 Re8 33.Be4? This move, losing a key pawn, is too cavalier and should just lose. Most players would just wait. However, black reacts inaccurately to give white one more chance on move 40.

33…Bxe4 34.fxe4 Rxe4 35.Rd1 Bc5 36.Rd3 f5 37.Re2 Kf6?! The clever 37….g5! is stronger here to rule out the white possibility mentioned in the note to white’s 40th move.

38.h3 h5?! And here, black had 38…Rf4+ and a later …g5, or 38…g5 right away. The idea is to take away h3-h4 for white.

39.Kf3 Ke5

Position after 39…Ke5. Last Chance.

40.Rd1? The last chance to resist was 40. h4! to hold black up on the kingside. White might even be able to hold the position with careful play; it’s up to black to demonstrate progress.

40…g5! Now it’s really all over. The rest is torture.

41.Rd3 Bb4 42.Rd1 Bc5 43.Rd3 g4+ 44.Kf2 h4 45.Kf1 Bb4 46.Rd1 Rxe2?! The simplest is 46… gxh3 47. gxh3 f4 with total domination.

47.Kxe2 Ke4 48.Rf1? Very bad. White has to try to hold the 3rd rank with 48. Rd3 and make black demonstrate a plan.

48…d3+ 49.Kd1 gxh3 50.gxh3 f4 51.Rg1 f3 52.Rg6 f2 53.Rf6 Bc5 White is paralyzed and gives up.

0-1

The Fabulous 00s: The 2008 US Championship Qualifier in Tulsa, OK

March 30, 2008

Tulsa!

The 2008 Qualifier was held in a restaurant-less roadside motel. Here’s a picture of a sushi train in the eponymously named nearby eaterie, Sushi Train.  See this post for some chess theory from the event.

sushi_train.jpg

The Sushi Train Comin’ to Getcha

Sushi Train was a hoot. The train circles the patrons continuously and it’s just one big fish pig-out. Ilya Gurevich and I used to go to a place in Japantown, San Francisco, with a similar (but smaller and less fancy) train. Sushi Train’s train was gaily decorated and had a little signal and warning bar that raised and lowered. It even had a locomotive with a little guy in there and a train-repair car! Of course, food critics might say “Fish in Tulsa??”

To get to Sushi Train, it was necessary to cross several major intersections. Chess players were often seen clutching their equipment bags and running for their life after “overlooking” some people had a green left turn arrow. Other attractions in the area included KMart, Chili’s, a boobie barn named “Tabu” and a rock music nightclub in the playing site. The playing site, some sort of Best Western, had no restaurant, opting for a rather bizarre “club only” option. Here’s a picture of the boobie barn which was conveniently located near a diamond wholesaler that was going out of business. Thus, a possible course of action is to pick up a 70% discounted diamond then head over to Tabu with some nice tips for the dancers in the form of loose stones.

Chess?

My own games were a dismal collection. After the “high” of Foxwoods, I had a “bummer”. Too many games packed into each day, an endless assortment of bad take out food (Fedorowicz looked at my gruel-like soup that I was slurping out of a styrofoam container and said “Looks Good”) and a nerve-wracking time control (G/90 + 30 sec delay) led to numerous shall we say sub-optimal resuls. For example, in Round 1 I lost to Coleman. FM Teddy Coleman? No, an expert, Maxx Coleman. My ingenious opening combination led to the immediate loss of a piece which he of course overlooked. The blunder fest continued with me walking into a knight fork. Bravo! After a few wins, I pulled up lame again with a loss to a candidate master, overlooking a one-mover in a slightly superior ending with no losing chances. Bravo!

There were a few chessic things worth mentioning.

Hanken Parts with the Dude

Round 1 saw a wipeout – GM Alex Yermolinsky dropped the People’s Elbow on Jerry Hanken when Jerry ignored every basic opening principle. You can’t do that against GMs. Hanken “parted with the Dude” (his own King) in short order on the white side of a Catalan, which is rather difficult to do.

Jerry Hanken – GM Alex Yermolinsky Round 1. A Catalan Not to Be Emulated.

1.c4 e6 2.g3 d5 3.Bg2 Nf6 4.Nf3 dxc4 5.Qa4 Nbd7 6.O-O a6 7.Qxc4 b5 8.Qc2 Bb7 9.d4 c5 10.Bg5 I believe this position was discussed in GM Beliavsky’s autobiography, Uncompromising Chess. But not the way this game develops.

10…Rc8 11.Qd1 h6 12.Bc1?? Ugh. Never anti-develop versus a GM.

12…Qb6 13.Nc3 cxd4 14.Qxd4 Bc5 15.Qh4 Ke7 16.g4 Ugh. 16…g5 17.Qh3 Qc7 18.Ne1 Ne5 19.Bf3 Rcg8 20.Nd3 Nxf3 21.exf3 Bd6 22.Ne4 Nxe4 23.fxe4 Bxe4 24.Ne1 h5 25.f3 Grotesque. A computer would have resigned. 25…hxg4 26.Bxg5 Rxg5 27.Qxh8 gxf3 0-1 I haven’t seen such senseless butchery since watching the CNN evening news.

Squelching the Moptop

Then in Round 2 we had a very instructional sequence. IM Josh Friedel in a very Russian-styled (think Lein of the old days) game neutralized and then tortured young Daniel Naroditsky when Daniel played a very slow King’s Indian “Attack” as white and then horribly weakened his own f4 square with an instructive positional mistake. That is a very youthful mistake; once a youth makes it, he or she remembers and it tends not to happen again! Trips to Russia will teach one how to play in that grand CCCP-torture mode. Here is the game:

FM Daniel Naroditsky – IM Josh Friedel Round 2 King’s Indian “Attack”

1.Nf3 d5 2.g3 c6 Many Russians play 2…Bg4 right away here.

3.Bg2 Bg4 4.O-O Nd7 5.d3 e5 6.Nbd2 Ngf6 7.e4 Bd6 8.c3 O-O 9.Qc2 Re8 10.h3 Bh5 11.Re1 Bf8 12.a4 a5 13.Nf1 This already is a bit suspect. What’s the horse doing?

13…dxe4 14.dxe4 Nc5 15.g4?? The moptop plays a dreadful move that causes no end of torture for himself.

15…Bg6 16.Ng3 Qd3! Of course. Now it’s cake for black. White just isn’t having any fun at all; why is the word ‘attack’ in this opening treatment?

17.Qxd3 Nxd3 18.Re2 Nd7 19.Nh4 N7c5 20.Be3 Rad8 21.Nxg6 hxg6 22.Nf1 Nb3 23.Rb1 Bc5 24.Bf3 Bxe3 25.Rxe3 Nf4

Total domination. A slightly older kid might resign right now with such a bishop battling such a knight.

26.Kh2 Nd2 27.Nxd2 Rxd2 28.Kg3 g5 29.b4 axb4 30.Rxb4 Re7 31.Rb6 Red7 32.Re1 Rc2 33.Rb3 Ne6 34.Rd1 Rxd1 35.Bxd1 Rc1 36.Bf3 Nc5 37.Ra3 Rc2 38.a5 Kf8 39.Bg2 Rb2 40.f3 Rb3 41.Ra2 Rxc3 42.Kf2 Rc4 43.a6 bxa6 44.Bf1 Ra4 45.Rc2 Ra5 46.Rb2 Ke7 47.Rb8 Ra2 48.Kg3 Ra3 49.Kg2 a5 50.Ra8 f6 51.Ra7 Kd6 52.Rxg7 Rc3 53.Rf7 Nd7 54.Ba6 a4 55.Bc8 Nb6 56.Bf5 a3 57.Rxf6 Kc5 58.Rf7 Nc4 59.Ra7 Rc2 60.Kg3 Ne3 61.f4 Nf1 62.Kf3 gxf4 0-1

Greed Should Not Be Good

In Round 3, a perplexing situation arose in a Sicilian versus NM Erik Santarius:

E. Santarius (2203) – IM M. Ginsburg Tulsa Qualifier, Round 3. Sicilian Scheveningen.

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e6 I am gaining confidence with this move after the epic Becerra encounter from Foxwoods 2008.

6. Bd3 Unusual and a little clunky and self-blocking. 6…Nc6! This must be the right reaction.

7. Be3 7. Nxc6 bxc6 promises zero.

7….Be7 8. f3 O-O 9. Qe2 Nxd4! A standard freeing strategem.

10. Bxd4 e5 11. Be3 Be6 Black has his share of the center and the chances are balanced. After all, white has not even managed to castle in either direction yet. But now the game takes a very strange turn.

12. Bc4!? Rc8 13. Bxe6?! I would prefer 13. Bb3 keeping an eye on things. I had no idea what he was up to at this point but it was really the next move that was the absolute shocker.

13…fxe6 14. Bxa7??! Oh. My. God. Did he really take that pawn? Never would I have guessed that any opponent no matter what rating would take this pawn. I don’t usually look at my opponent, but this time I had to take a quick glance to see if he had gone non compos mentis. He looked normal so my sanity check didn’t work. The text seemed at the time to be totally nuts and/or the product of a bad computer program circa 1990. Can he really do that? At the time, I thought “No way!”. He’s not castled, I have possibilities of Rxc3 and Qa5 with a subsequent d6-d5 breakout, or b6 trapping the guy long-term, or Qa5 right away keeping b6 in reserve, or d6-d5 right away keeping Rxc3 and Qa5 in reserve. So many juicy and titillating choices! Running computer programs on the position is a real mother-lode of interesting possibilities now, so in practical terms his pawn snatch really puts the onus on me to be accurate in a very limited time setting (Game/90 + 30 sec delay was the time control).

The variations now are incredible – the hunt for punishment for this move takes a number of twists and turns.

Readers: I will complete this game post soon; for the time being, just look and decide what you think is Black’s best here. Can I punish this audacious, un-castled, pawn grab? Signs point to yes, yes? So what’s the right move?

santo_0.png

Position after 14. Bxa7??! – How to punish the greed?

Before posting the rest, I will just note that the game was drawn, with black barely holding a bad ending with R&active N vs RR.

4/3/08: As promised, here is the rest of the game.

14…Rxc3? Not a good reaction. First of all, black has 14… b6!? – a good move and ambitious. 15. Qa6 (15. Nb5 Qd7 16. a4 Ra8 17. a5 bxa5 18. Rxa5 Rfb8!! Black would need good tactics to see this move way ahead of time. Black is now slightly better. 19. O-O Rb7 20. c4 Bd8 21. Ra6 Rbxa7 22. Nxa7 Rxa7 23. Rxa7 Qxa7+ 24. Kh1 Bb6 25. b4 Bd4 26. b5 Nd7 and black is very good. Or, 15. a4 Rxc3! 16. bxc3 Qc7 17. Qe3 Qxa7 18. a5 Nd7 19. O-O d5 and again black is doing well. I did not see the shot on my 14th move. Returning to 15. Qa6, 15… Nd7 16. a4 Bh4+!? (16… Rxc3 17. bxc3 Qc7 18. Ke2 Qxc3! The strongest. Black is a little better.) 17. g3 Rxf3 18. a5 Re3+ 19. Kf2 Nc5 20. Qb5 Qg5 and now let’s show a nice sample variation: 21. Ne2 Nxe4+ 22. Kg2 Nxg3 23. hxg3 Rxg3+ 24. Kf2 Qe3+ 25. Kf1 Rf3+ 26. Kg2 Qf2 mate.

Black also has the tantalizing 14… d5?! – at the time, I thought about this move quite a bit with the idea of Rxc3 next. However, white maintains an edge if I take the n/c3 next turn and I did not understand that. There might follow 15. exd5 exd5! This simple recapture never occurred to me. It’s about equal. (I had focused on 15… Rxc3? 16. bxc3 Qa5 and this is refuted by 17. Qxe5! Qxa7 18. Qxe6+ Rf7 19. Rd1 and White is simply better here. Black has no avenues of attack.) 16. O-O-O (An important variation is 16. O-O!? b6 17. Nb5 Bc5+ 18. Kh1 e4 19. a4 Nh5 A very nice slow-motion positional move, ignoring the queenside piece formation. 20. g3 (20. a5 Nf4 21. Qd1 e3 22. Nc3 bxa5 23. Bxc5 Rxc5 24. Re1 d4 25. Ne2 Ne6 26. Qd3 Qd6 27. Kg1 Rg5 28. Qe4 Rb8 29. b3 Re5) 20… Qd7 21. f4 Qh3 with a mess.

Returning to 16. O-O-O, 16… Rxc3 17. bxc3 Qa5 18. Bf2 Qxc3 19. Kb1 Qb4+ 20. Kc1 Qa3+ 21. Kb1 Bb4?? loses, 22. Qxe5 Bc3 23. Qe6+ Kh8 24. Qb6 Cold shower! White wins. This means black should take the perpetual check draw.

There also is 14… Qa5 , a fine, solid choice. White has to play 15. Bf2 — if 15. Qe3?? Nd7! and oops! White loses the bishop on a7 and the game. I don’t even think I saw this simple possibility – it’s a nice trap.

White has another inferior choice, 15. Be3?! This is dubious, but it takes sharp vision to know why. The answer is 15… d5! and NOT 15… Rxc3?? 16. Bd2! – oops!

After 15….d5!, 16. Bd2 Qc5 17. exd5 exd5 : in this bizarre scenario, white cannot castle in either direction. If the greedy 18. Qxe5? Bd6 19. Qf5 Rce8+ 20. Kd1 (20. Kf1 Ne4! wins) 20… Qf2! and White’s position crumbles. For example, 21. Qg5 (21. Qh3 d4 22. Ne4 Nxe4 23. fxe4 Rxe4 24. Qd3 Qxg2 25. Re1 Qg4+ 26. Kc1 Rxe1+ 27. Bxe1 Bf4+ 28. Kb1 Re8 {A total rout; white must resign.}) 21…Re5 22. Qg3 Re1+ 23. Bxe1 Qd4+ 24. Kc1 Bxg3 25. Bxg3 Qc4!! A beautiful tactic. It shows how black has to open the game versus the loose, uncastled, WK in order to win.

Returning to the game,

15. bxc3 Qa5 16. Qe3! d5 17. a4 Qb5 This position is worse for black than I thought during the game.

18. Bc7?! Indicated is 18. a4 Qc4 (18… Qc6 19. O-O d4 20. Bxd4! exd4 21. cxd4! and white is much better – black’s minor pieces have no perspectives) 19. Qd3 Qc6 20. Ba5 with white edge.

18… Nd7? Correct is 18… dxe4! with full counterplay. This simple move was simply not on my radar.

19. exd5 exd5 20. a4? The grab 20. Bxe5! is correct and black cannot exploit the WK. White should win that.

20…Qc6 21. Ba5 e4 22. Bb4 Bh4+ 23. Kd1 Re8 24. Rf1 Bf6 25. a5 h6? Bad move! This game really showed a lot of inaccuracies in such a short time, on both sides.

Correct is 25… Ne5! and black is all right.: 26. Qc5 (26. fxe4 dxe4 27. Qc5 Qe6 28. Kc1 Nc4 29. Qh5 e3 30. Qe2 Rc8 {Full positional compensation.}) 26… Qe6 27. Re1 Nc4 28. Qb5 Bg5 29. Qxb7 Ne3+ 30. Kc1 exf3 31. Kb2 f2 32. Rxe3 Bxe3 33. a6 Qf7 and it is equal.

26. f4! Of course. White has control again.

26…Rc8 27. Rf2 Qc4 28. Qe2 Bxc3 29. Qxc4 Rxc4 30. Bxc3 Rxc3 31. Rb1 e3 32. Rf3 Nc5 33. Rb4 Kf7 34. f5 Kf6 Of course black should lose but in this crazy time control (G/90 + 30 sec increment), well played endings are impossible.

35. Rg4 Ra3 36. Ke2 Rxa5 37. Rxe3 Ra2 38. Rc3 Ne4 39. Rc7 Kxf5 40. Rgxg7 b5 41. Kd3 Ra1 42. Ke2 b4 43. Rgf7+ Ke5 44. Rf1 Ra2 45. Re1 Kd4 46. Kf3 Nc3 47. Rc1 Ra6 48. Rf7 Re6 49. Rf4+ Kc5 50. Ra1 d4 51. Ra5+ Kc4 52. Rff5? In time pressure, white missed 52. Ra8! Re3+ 53. Kg4 Re2 54. Rc8+ Kd5 55. Rd8+ Kc5 56. Rf5+ Kc6 57. Rxd4 Rxg2+ 58. Kh3 Rxc2 59. Rc4+ Kd7 60. Rxb4 and wins. Not an easy variation.

52… Re3+ Immediately equal was 52… b3 53. cxb3+ Kxb3 =

53. Kg4 b3 54. cxb3+ Kxb3 55. Rf2 d3 56. Ra6 Ne4 Black tricks himself with 56… h5+ 57. Kxh5 Ne4 58. Rf8 d2 59. Rd8 Re2 60. Rc6 Nc3 61. Rd3!! and wins.

57. Kf4 Re1 58. Re6?! White can dance around and eventually prevail with 58. Rf3 Nc5 59. Rc6 Kb4 60. Rf2 Nb3 61. Rb6+Kc4 62. Rd6 Kc3 63. Rd8 Nc5 64. Kg4 Re2 65. Kf3. However, he had very little time and decided to go for the easy draw.

58… Nxf2 59. Rxe1 d2 60. Rf1 Kc3 61. g4 Kd3 62. Kf3 d1=Q+ 63. Rxd1+ Nxd1 64. h4 Ne3 65. Kf4 Ng2+ 66. Kf5 Nxh4+ 67. Kf6 Nf3 68. Kg6 1/2-1/2 Almost to the proverbial last pawn.

Dealing with the Semi-Slav Harshly

In the entire Tulsa event, I had one bright spot in a game vs. Conrad Holt:

IM M. Ginsburg – C. Holt, Tulsa Qualifier 2008. Round 4. Slav Defense.

1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. g3!? I like this gambit idea without the knight yet on c3. Magnus Carlsen had some nice wins with this line recently. In particular, I believe he dispatched the veteran GM Lajos Portisch rather convincingly.

4…Bf5 5. Bg2 e6 6. O-O Nbd7 7. Nc3 Bd6 8. Nh4 Bg4 9. h3 Bh5 It’s useful to put bishop a little offside. White shouldn’t go crazy, though, and expose his own king to attack.

10. Qb3 Rb8 10…Qb6 11. c5! is no fun at all for black. After 11…Qxb3 12. axb3, b3-b4-b5 happens.

11. cxd5! The right moment. Now black cannot take back with a pawn and so must take with the knight, and this concedes white a big center.

holt_0.png

Position after 11. cxd5! – I am at least doing something right this tournament.

11…Nxd5 12. e4 Nxc3 13. bxc3 O-O 14. f4 b5 15. Nf3 Bxf3 White forced this concession. The two bishops will become very powerful when the game opens up.

16. Bxf3 c5 Black is doing his best to make counterplay. Now I hatch a very strong idea to defuse black’s principal idea of b5-b4.

17. e5 Be7 18. f5! The key idea. White must attack quickly and open the game for the bishops.

holt_1.png

Position after 18. f5! – Hurry-up offense.

18…exf5?! I would prefer not taking although white is clearly better. The text gives up the d5 outpost.

19. Bf4! g5? Suicide and a move I did not really expect to see. Any other move defending against e6 would be better.

20. Be3 b4 21. Qc2! Black is now toast due to the threat of Qxf5 and Be4, mating. The rest of the game is a mop-up with the bishop pair showing some stylish variations near the end.

21…Qb6 22. Qxf5 Qe6 23. Qe4! The threat of Bg4 is lethal.

23…Qxh3 24. Rf2 Qh6 25. Bg4 Rbd8 Now, with a big time edge, I got confused. Can I win/mate with 26. Rh2 Qg7 27. Bf5 h6 28. Kg2 with the idea of doubling rooks on the h-file and jettisoning my c- and d-pawns? Suppose I calculate wrong? Things get kind of sharp. More perplexing, after black takes on c3 and proceeds to take on d4, I might be able to recapture on d4. But this doubling on the h-file looked so primitive! In the end, I decided just to advance my monster center pawn duo.

26. d5 (!) The simplest. 26…Rfe8 To guard against d6 winning the bishop.

27. Raf1 Bd6 28. e6! Crushing.

28…fxe6 29. Bxe6+ Kh8 30. cxb4! It’s always nice to be able to afford moves like this. White is simply playing to get on the a1-h8 diagonal.

30…Bxg3 31. bxc5 So obvious it does not merit an exclamation. 31…Bxf2+ 32. Rxf2 Nf6

holt_2.png

Position after 32…Nf6

33. Bd4! A little embarrassing would be 33. Rxf6? Qxf6 34. Bd4 Rxe6! – a nice and unusual trick exploiting various pins – allowing black to play on after 35. Bxf6+ Rxf6 36. Qe7 Rdf8. White might win, but why bother? The text puts black in a terminal bind.

33…Rf8 34. c6 Qg7 35. Qe5 Nh5 36. c7! With utter destruction. Black resigned. If only my other Tulsa games were coherent.

Here’s a fascinating tangle from Round 4.

IM Blas Lugo – GM Jesse Kraai French Exchange


1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 dxe4!? 5.Nxe4 Be7
A favorite treatment of GM Evgeny Bareev. This is not as quiet as it appears since the kings wind up on opposite sides often. It has the advantage of avoiding many long mainline theory variations.

6.Bxf6 Bxf6 7.Nf3 Nd7 8.Qd2 O-O 9.O-O-O Be7 10.Bd3 b6 11.Kb1 The primitive 11. h4 turned out to be too slow in Suetin-Bareev, Hastings 1991, and black won after 11…Bb7 12 Kb1 Nf6. To give a counter-example, White won after 11. h4 Bb7 12. c3!? Nf6 13. Neg5 Bxf3 14. gxf3, but this position is equal after 14…Qd5. Black played 14…Kh8?! and lost in Topalov-Dreev, Linares 1995. The text move, on the other hand, also doesn’t promise much – only 3 draws in Chessbase’s BigBase. A more dangerous try is 11. Neg5!? which hopes for 11…h6? — after 11. Neg5 h6?, white scored +4 =0 -0 in ChessBase! But there’s a curiosity here: in Volokitin-P.H. Nielsen, Germany 2004, the game went 11. Neg5 h6 12. Bh7+ Kh8 13. Be4 which at first glance looks good for white. However, at first glance black missed 13…hxg5 14. Bxa8 g4! and the threat of Be7-g5 wins material for black! In the game, black played 13…Bxg5 14. Nxg5 Rb8 and lost. However, he was doing OK after 15. Nf3 Nf6 16. Bc6 Qd6 17. Ne5 Ng4! 18. Nxg4 Qc6 – he only lost due to later middlegame miscues. The truth about 13…hxg5? is revealed in another example, J. Polgar – F. Berkes, Budapest 2003, white introduced an incredible gambit: 12. Bh7+ Kh8 13. Be4 hxg5? 14. g4!! (not the greedy 14. Bxa8?) and now black faces complex problems. White stops black from playing g5-g4 and prepares to open the h-file. In the game, black lost after 14…Rb8 15. h4 g6 16. hxg5+ Kg7 17. Qf4 and white crashed through. The question is, can black live after 14. g4? Let’s take a look. First of all, 14….Ba6 15. h4! gxh4 16. g5! is crushing. For example, 16…Kg8 17. Rxh4 f5 (What else?) 18. Bc6 Rc8 19. Rdh1 Kf7 20. d5! and wins. Let’s go back to Berkes’s choice, 14…Rb8. 15. h4 and first we see that 15…gxh4? is bad: 16. g5 g6 17. Rxh4+ Kg7 18. Rdh1 Rg8 19. Rh7+ Kf8 20. Qf4! and wins.

So we go to Berkes choice, 15…g6 16. hxg5+ Kg7 17. Qf4. This is critical. We first notice that 17…Ba6 is crushed by a typical Judit Polgar brute-force tactic 18. Rh7+!! Kxh7 19. Qh2+ Kg8 20. Rh1 Bxg5+ 21. Nxg5 Qxg5+ 22. f4! and wins. We also notice that Berkes’s choice, 17…Bb7?, was crushed by the same tactic.

what about 17…Rh8!? – trying to defend on the h-file. There follows 18. Rxh8 Qxh8 (forced) 19. Ne5! and now black cannot take: 19…Nxe5? 20. Qxe5+ Kg8 21. Qxc7 Bxg5+ 22. Kb1 and the rook on b8 is trapped; white wins. And after 19…Qe8 20. Rh1! the lethal threat of 21. Nxf7! is introduced. Black still cannot take on e5 and hence is lost.

Going back to the beginning, 11. Neg5!? is best met by 11…Bxg5! and now 12. Qxg5 Qxg5+ 13. Nxg5 Nf6 is dead equal. Or, 12. Nxg5 Nf6 and black is OK and even won in B. Lopez-Kraai, San Diego 2004. That game continued 13. Qf4 Bb7 14. Rhe1 Qd6!? and here white disdained an equal ending after 15. Qxd6, opting for 15. Qh4 h6 16. Nf3 (16. Ne4! equal) Bxf3 17. gxf3 Nd5 18. Re4, eventually getting into trouble with the weak d4 pawn. White tried 13. h4!? in Sax-Dizdar, Celje 2003, and black reacted suspiciously with 13…c5?! 14. dxc5 Qd5 15. Kb1? Qxc5 equal. But white missed 15. Qf4!! Qxa2 16. Nxh7! Nxh7 17. Qe4 Nf6 18. Qxa8 Qa1+ 19. Kd2 Qxb2 20. Qxa7 and white keeps a small plus. Stronger is 13. h4 Bb7! and black is fine.

11…Bb7 12.Qf4 c5 In Sindik-Dizdar, Pula 1993, black introduced an idea similar to the game: 12…Qb8!? 13. Qg3 c5! with good play. White can improve with 13. Ne5! c5 14. Bb5! Nf6 with sharp play after 15. Nxf6+ Bxf6 16. Rhe1 and now the Korchnoi pawn grab 16…Bxg2!?

13.dxc5 Qb8! Gambits in opposite-castled king positions are effective even in the ending! This is particularly true in the “perpetual time pressure” time control of G/90+30 sec.

14.Qxb8 Raxb8 15.cxb6 Nxb6 16.b3? Correct is the solid 16. Ned2! and hunkering down. This would not create the c3 weakness in the game.

16…Na4! Very unpleasant to meet in this time control. White probably overlooked this.

17.Rde1 Bxe4 18.Bxe4 Nc3+ 19.Kb2 Bf6 This position is terrible for white.

20.Bd3 Ne4 21.Kb1 Nxf2 22.Rhf1 Nxd3 23.cxd3 Rfd8 24.Re3 a5 25.Ne5 Rd5? Correct is 25…Bxe5 26. Rxe5 a4! and black is on top. For example, 27. Kc2 axb3+ 28. axb3 Ra8 29. Kc3 Ra2 with a huge initiative.

26.Nc6 Rb7 27.Rg3 Kf8 28.Rf4! White is doing the right things now to get back in the game.

28...Be5 29.Nxe5 Rxe5 30.Rc4 f5 31.Rf3? 31. Kc1!

31…Ke7 31…Re2! is strong. 32.Rf2 Rd7 33.Kc2 Red5 34.Rf3 Kf6 35.Kc3 g5 36.d4? 36. h4! to reduce the number of pawns.

36…f4 37.a3 Kf5 Now black is gaining control again with his monstrously active king.

38.Rc5? White had to wait with 38. Rf2. The pseudo-active text is crushed.

38…g4 39.Rf1 e5! White probably underestimated this.

40.Rxd5 Rxd5 41.dxe5 Rxe5 42.Kd2 h5 43.b4 axb4 44.axb4 h4 45.Rb1 f3 46.gxf3 gxf3 47.b5 Kg4! The key move. White is lost.

48.b6 f2 49.b7 Re8 50.Rb4+ Kh3 51.Rb3 Kg2 52.b8Q Rxb8 53.Rxb8 f1Q 54.Re8 0-1
