3 Decades of a Variation

October 1, 2007

I have always been interested in sidelines, particularly in Gruenfeld structures. Here are two games spanning 27 years on the same theme.

Let’s start with the happier, and more recent, game.

IM M. Ginsburg – NM Ralph Zimmer

North American Open, Las Vegas, NV 12/28/05

1. c4 c5 2. Nf3 Nc6 3. Nc3 g6 (?!) Purists believe this move order is slightly inaccurate. However, it might not be true – see the Ibragimov game mentioned in the note to the 8th move and if you believe in black’s position, try it out. The text gets ?! in some books, but it may not be necessarily so.

4. e3! Nf6 The text is correct, preparing a Gruenfeld-like d7-d5 advance. A further inaccuracy, which is important to mention because it occurs frequently, is 4….Bg7?!. White then plays the simple 5. d4 cxd4 6. exd4 d6 7. d5! and stands seriously better. For example, 7…Ne5 8. Nxe5 Bxe5 9. Bd3 Bd7 10. O-O Nf6 11. h3 O-O 12. Be3 a6 13. Rc1 Bd7 14. Na4! b5 15. Nb6 Rb8 16. Nxd7 Nxd7 17. cxb5 axb5 18. b4! with a nice bind, M. Ginsburg-Gilruth, Harry Nelson Pillsbury Open New England, 1987. White duly won in 46 moves.

5. d4 cxd4 5…d6 6. d5! with a small white edge is playable.

 

In 1989 I faced Senior Master S.C. Sahu (2417) at the Manhattan Chess Club and had a pleasant experience: 6. d5 Ne5 (6…Ng8 just admits opening failure) 7. Nxe5 Bxe5 8. e4 Nf6 9. Bd3 Ng4? The Rybka-approved line, 9…Bd7 10. O-O Qb6!? 11. h3 O-O, looks highly unnatural but the text is simply bad. 10. h3 Nf6 11. Bh6 Rg8 12. Qd2 Qa5 13. f4 Bd4 14. Nb5! Bf2+ 15. Ke2 Qxd2+ 16. Kxd2 Kd8 17. e5 Ne8 18. Rhf1 a6 19. Nxd6! White wins easily. 19…Nxd6 20. Rxf2 Nf5 21. Bg5 h6 22. Bxf5 gxf5 23. Bxh6 f6 24. d6 Be6 25. dxe7+ Kxe7 26. exf6+ Kf7 27. Bg5 Rad8+ 28. Kc3 Rd4 29. b3 Rgd8 30. Re1 b5 31. Rfe2 R8d6 32. g4 bxc4 33. gxf5 Rd3+ 34. Kb2 c3+ 35. Ka3 Bxf5 36. Re7+ Kg6 37. Rg7+ Kh5 38. f7 Rd8 39. Bxd8 Rxd8 40. Rg8 1-0

 

6. exd4 d5 7. cxd5 Nxd5 8. Bc4 Nxc3? It is this move that is seriously wrong. Here, 8…Nb6 is the only correct move in my opinion. Play might proceed 9. Bb3 Bg7 10. Be3!? (10. d5 Na5 is nothing) 10…O-O 11. O-O Na5 12. Bc2 Nac4 13. Bg5!? with murky play, Ibragimov-Kedrov, Moscow 1996. Black lost this game, but he’s OK here and only lost via blunders in the middlegame.

9. Qb3!

zimm1.png

The first important moment. The zwischenzug text is accurate, because 9…Ne4? 10. Bxf7+ Kd7 11. Qe6+ and 12. Qxe4 is clearly out of the question. I had this game in a 1993 USATE playoff and won easily. The position is very good for white.

9…e6 10. bxc3 Na5 10…Bd7 11. Bb5! (or 11. Bd3 right away, for example 11…Qb6 12. O-O Qxb3 13. axb3 Bg7 14. Ba3 and white is much better, and won, in Charbonneau-Tan, Oropesa del Mar 2001) 11…a6 12. Be2 Na5 13. Qc2 b5 14. O-O is very good for white. In the next game, we will see the semi-insane “gambit” 10….Bd7 11. d5??! (THEORETICAL LEMON, TL) Na5 12. dxe6 relying on the fact that the queen is immune for the time being. However, as we shall see, 12…fxe6 is basically the refutation of this “junior” attack. See the second game for more on this crazy line.

Black can also try 10…Bg7. But after 11. Ba3, stopping castling, white is better. For example, 11…Bf8 (what else?) 12. Bxf8! Kxf8 13. O-O and white is much better. Note for historical purposes the American future GM Ken Rogoff played the fine 12. Bb5!? here and stood better, but lost due to a later blunder vs. the Frenchman Huguet in Malaga 1970. 12. Bb5 was also seen in a drawn Botvinnik-Petrosian game, Moscow 1983. Another good move is 12. O-O! and white also stands better here.

11. Bb5+ Bd7 12. Qa4 Nc6 13. d5! 13. O-O is good for white, and the well motivated attacking text aims for even more. Clearance sacrifices, exposing the enemy king, are always extremely difficult to meet in practical play.

zimm2.png

13…exd5 14. O-O Be7 15. Bh6 f6? A much better try is 15… Qa5 16. Qb3 O-O-O 17. c4 d4 18. Ng5 Bf8 19. Bxf8 Rhxf8 20. c5 Qc7 and black stays afloat. The text weakens e6 severely and could have had fatal consequences in the near-term.

16. Rfe1 Kf7

zimm3.png

17. Qf4? The text looks and is absurd. The best move is extremely simple-minded 17. Rad1!. This position is a good test of attacking abilities. Those with a quick eye will recognize that 17…Be6 is smashed (note in passing that 17…a6 18. Bc4!! dxc4 19. Qxc4+ Ke8 20. Bg7 Rf8 21. Qh4 Rf7 22. Qxh7 Rxg7 23. Qxg7 wins, for example 23…Ne5 24. Qg8+ Bf8 25. Qxg6+ Ke7 26. Nxe5 Be6 27. Qf7+ Bxf7 28. Ng6 mate which is especially gruesome) by 18. Rxe6!! which is completely crushing. Once the white squares fall, the black king is cornered. 18…Kxe6 19. Bc4 and white wins shortly.

17… Bf5 18. Rad1 Bd6 19. Qd2 Ne7 19… Be7 20. Qb2 threatening c4 is very good for white.

20. Nd4 Bg4 21. Rb1 Curiously, 21. Qe3! is strong here.

21…a6 22. Be2 Bc8 23. Bd1 Re8 24. Bb3 Bc5 25. h3?! Here, 25. c4! Bxd4 is met by the surprising zwischenzug 26. cxd5! (26. Qxd4 is also good, but this is stronger) and white is much better.

25… Bxd4 26. Qxd4 Be6?? A bad blunder. Necessary is 26…b5! 27. Rbd1 with a white edge but nothing decisive yet. Now we have yet another tactical exercise with the same solution!

zimm4.png

27. g4?? A blunder in return. 27. Rxe6!!, a thematic blow we’ve already seen above, wins nicely. For example, 27…Kxe6 28. Qe4+ Kf7 29. Rd1! is a very pleasing double pin and black is paralyzed and loses shortly. For example, 29…f5 (equally bad is 29… g5 30. Rxd5 Nxd5 31. Bxd5+ Qxd5 32. Qxd5+ Kg6 33. Bxg5 fxg5 34. Qxb7 and wins) 30. Rxd5! fxe4 31. Rf5 double checkmate is a nice geometric spectacle.

27…Nc6 28. Qf4 Qb8 Now black is right back in the game. Also acceptable is 28… Kg8 29. Re3 g5 30. Qg3 Bf7 31. Rxe8+ Qxe8 32. f4 d4.

29. Qd2 Qd6 The position is about level.

30. Bf4 Qd7? 30…Ne5! is rock solid for equality.

31. Re3 Now, 31. Rxe6! Kxe6 is still a good try: 32. Bg3 Ne5 33. Bxe5 fxe5 34. Bxd5+ Qxd5 35. Rb6+ Qc6 36. Rxc6+ bxc6 37. f4 exf4 38. Qxf4 Re7 39. g5! with some winning chances for white. It stands to reason that white is still blind to this possibility.

31… Kg7 32. Bh6+ 32. Rbe1 Bf7 33. Bh6+ is a small edge to white.

32… Kh8 33. Qe2 Ne5 This is fine. Also fine is 33… Bf7.

34. Re1 Bf7 35. g5 Nc4?! Solid is 35… Kg8 36. gxf6 Nc4 37. Bxc4 Rxe3 38. Qxe3 dxc4 and black is fine.

36. Bxc4? Very weak. 36. Re7! poses some problems for black.

36…Rxe3 37. Qxe3 dxc4?! Another inaccuracy. But black had no time and cannot be criticized. In fact, at this moment, black forfeited on time still a few moves shy of the time control at move 40. A good defense was 37… Re8 38. Qd2 Rxe1+ 39. Qxe1 dxc4 40. gxf6 Qe6 and it’s completely drawn.

1-0

After the weak text, white could find 38. Qb6 Qc6 39. Qxc6 bxc6 40. Re7 Kg8 41. gxf6 a5 42. a4 with a rather unpleasant ending for black.

 

Now let’s go back to my 1978 game in the ECI Youth tournament, Sas Van Gent, Holland. This is the tournament where I met the personable British youth player Suzzane Wood! Note her first name is not misspelled.

M. Ginsburg – NM Erik Pedersen (DEN)

ECI Sas Van Gent, Holland August 1978

1. c4 c5 2. Nf3 Nc6 3. Nc3 g6 4. e3 Nf6 5. d4 cxd4 6. exd4 d5 7. cxd5 Nxd5 8. Bc4 Nxc3 9. Qb3! So far, as above.

9…e6 10. bxc3 Bd7!? Pedersen’s specialty, he played it another European tournament – Groningen 1978 (perhaps later, I’m not sure about that). However, the position is good for white!

11. d5??! THEORETICAL LEMON, TL. 11. Bb5, 11. Be2, and 11. Bd3 are all very good for white. 11. Be2 Na5 12. Qc2 Qc7 13. Ne5! (13. O-O is also good for white) Rc8 14. Bd2? (14. Rb1! or even the simple 14. Nxd7 Qxd7 15. O-O and white is better) 14…Bg7 15. f4? (15. Qe4!) and white even lost with this bad structural weakening, Grinberg-Pederson, Groningen 1978. See the first game for other examples of white doing well here.

12…Na5 12. dxe6 My “amazing point.”

peder1.png

12…fxe6! Oh. He had that? I had “expected” 12…Nxb3?? 13. exf7+ Ke7 14. Bg5+ Kd6 15. Rd1+ Nd4 16. Bxd8 Rxd8 17. Nxd4 and I win easily. A very naive “junior” assessment. The text is the start of a very cold shower.

13. Qd1 What else? This is my “secondary point” – that 13….Nxc4 14. Qd4 “wins the piece back”.

Time for another tactical quiz. What’s black’s best move?

peder2.png

13…Bg7? Wrong. The text is winning (and black did win the rather long, drawn-out ending after 14. Be2 Bxc3+), however black had better: (quiz solution:) 13…Nxc4 14. Qd4 Ba4!! A very unusual and crushing shot! Black can safely leave a couple of pieces hanging. 15. Qxh8 Qd1 mate is unplayable and so is 15. Qxc4 Qd1 mate, so black remains a piece up!

At any rate, black had no problem converting the pawn up ending in about 50 moves (he correctly didn’t accept the exchange sac on a1 and just played an ending with one pawn more).

0-1

The Fabulous 00s 2007: The Continental Open

August 16, 2007

Sturbridge, Massachusetts is pleasant in August. There’s Echo Lake, outdoor taverns, and the usual New England whatnot. So I journeyed up to one of the indefatigable Bill Goichberg’s events, the 37th Annual Continental Open.

Here are some crazy G/1 hr. games I played.

Elizabeth Vicary – Mark Ginsburg Round 1, Continental Open 2007

Sicilian 2…e6 3. b3!?

Elizabeth arrived a little late for the board which is always a handicap in a G/1 hour match. That’s how I lost to GM Akobian. The moral is to avoid it if possible (she had car problems which are hard to “refute”). I was late in the Akobian (Las Vegas) game simply by being in a long coffee line in the verdammt Bally’s hotel. This game features incredible variations with most perplexing piece placements (alliteration!) that remained behind the scenes.

1. e4 c5 2. Nf3 e6 3. b3!? b6!? 4. Bd3 Nc6 5. O-O Bb7 6. Re1 Nge7 This looks like the best; when the knight gets to g6 it eyes the tender f4 spot.

vic.png

7. Bb2 Ng6 8. Na3 Be7!? 9. Nc4!? Of course white can grab the pawn with 9. Bxg7, but in a fast game it’s not so much fun. Black will play 9. Bxg7 Rg8 10. Bh6 (awkward but necessary to prevent knight jumps to f4) 10…Qb8 with good prospects for kingside counter-action.

9…O-O 10. c3?!

Here, 10. e5!? is sensible to gain space and thematic and 10. a4 is perfectly good too. The text is self-blocking. On second thought, 10. e5 isn’t so great: 10…Nf4! and now if 11. Bf1 f6! seems fine, or if 11. Be4 then 11…f5!. So I will leave myself recommending 10. a4.

10…d5 11. exd5 exd5 11…Qxd5 12. Be4 Qd7 is OK but approximately equal.

12. Ne3! 12. Nce5? Ncxe5 13. Nxe5 Nxe5 14. Rxe5 Bd6 is clearly good for black.

12…Re8 13. Bc2? The only way to justify the 10th move is by playing 13. Bxg6! hxg6 14. d4! with good chances for equality.

13…d4! By far the best move. In fact, it was stronger than I realized at the time.

14. cxd4

vicary2.png

14…Nb4!? A very tricky and interesting try, but black had the stronger and rather obvious 14… Nxd4! and after 15. Nxd4 cxd4 16. Nf5 d3! wins, using the motif of dividing the board in two to build up a decisive initiative. White has to play 17. Bb1 undeveloping the queenside and gets in a losing bind. This I had not appreciated. Play can continue 17…Qd5 18. Ne3 Qg5! and everything is happening with gain of tempo. White defends with 19. g3 (19. Bxd3 Nf4 loses) and then black continues the attack with 19… Nh4 20. f4 Qg6 21. Kf2 Nf3 22. Rh1 Bc5 23. a3 Nxd2! and wins in a gruesome finale.

15. Bb1 Nf4! 15… Bf6 is less strong – 16. a3 Nc6 17. Bxg6 hxg6 18. Qc2 Nxd4 19. Nxd4 Bxd4 20. Bxd4 cxd4 21. Nf1 and white holds on.

16. Ne5? Strongest here is 16. dxc5! and now there’s a funny variation. Black might fall into 16…Nfd3? (16…bxc5! is reliable; 16…Nbd3!? is probably somewhat worse due to the in-between move 17. c6!) 17. Ne5! Nxe1?? (white is on top anyway, but this loses) 18. Bxh7+!! winning in all variations. 18…Kxh7 (witness 18… Kf8 19. Qh5! Bd5 20. Nxd5 Qxd5 21. Qxf7+! Qxf7 22. Nd7 mate! – a savage and really unusual finale that deserves a diagram, see next!)

vicary31.png

Position after 22. Nd7 mate – analysis

19. Qh5+ Kg8 20. Qxf7+ Kh7 21. Qg6+ Kg8 22. Nf5! Bf6 23. Nh6+ Kh8 24. Nef7 mate. It’s strange how white gets a crushing attack seemingly out of nowhere in this line.

16… cxd4? The optically somewhat ugly 16… f6! is surprisingly strong and leaves black with a big plus in the mutual dance of the knights. For example, 17. N5c4 Nfd3. The text gives white a hidden way out.

17. Nf5 This move is not good, but not as bad as I thought at the time. I thought 17. Qg4! was forced and now 17…dxe3 18. Qxf4 holds for white although it looks at first glance very precarious. For example, 18…Bf6 19. Rxe3 Nd5 20. Qf3 Nxe3 21. Bxh7+! Kxh7 (Not 21…Kf8 22. Ba3+! Re7 23. Qxb7! Nd5 24. Nd7+ Ke8 25. Nxf6+ gxf6 26. Qc6+ Kf8 27. Be4! with a total rout) 22. Qh5+ with a perpetual check mechanism for the draw.

17… Bf6 The move does win, but tricks remain.

18. Qg4? Now black really does win easily with an extra piece. But white had 18. Bxd4 Nxg2 and now the strange tactical lunge 19. Qh5!! for excellent tricks in time trouble. Look at this for a moment.

vic_qh5.png

Position after 19. Qh5!! (Analysis)

This is a really unique situation. It’s not even easy to see white’s threats, but they are real. White cannot play, by the way, the passive 19. Re2? Nh4 20. Nxh4 Bxd4 as the bishop on d4 hangs and Qg5+ is threatened. But after 19. Qh5 things are very strange. First of all, 19…g6 20. Nh6+! Kf8 21. Bxg6!! is an amazing resource. It deserves another diagram.

vic_bg6.png

This shocking blow makes the game very weird and unclear. Taking it further leads into crazier and crazier tactical complications. Let’s try: 21…Nxe1 (much weaker is 21…hxg6 22. Nxg6 hxg6 23. Qxg6 Rxe1+ 24. Rxe1 Bd5 25. Bxf6 wins for white) 22. Bf5! Re7 23. Qg4 Bg7 24. Nd7+ Ke8 25. Nf6+ Kf8 26. Nxh7+ Ke8 27. Qxg7 Nf3+ 28. Kg2 Nxd4+ 29. Kh3! and wins. But I would be amiss if I didn’t point out the hilarious variation 29. f3? Re2+ 30. Kf1 (Amazingly 30. Kh3?? gets clobbered to 30…Rxh2+!! 31. Kxh2 Nxf3+ 32. Kh3 (or 32. Kg2 Qxd2+ and wins) Qh4+ 33. Kg2 Qh2+ 34. Kf1 Nxd2+ 35. Ke1 Nf3+ 36. Kf1 Ba6+! 37. Bd3 Bxd3 mate!) Qd6!! (a phenomenal defensive and offensive resource) 31. Nf6+ Ke7 32. Qxf7+ Kd8 33. Qxb7 Rf2+!!! (Black’s turn to find a shocking resource!) Let’s look at this:

vic_rf2.png

Position after 33…Rf2+!!! (Analysis)

What a move. If it actually occurred OTB, it would make the pantheon of shocking coups. First of all, white cannot get cute and decline: 34. Ke1?? Qe5+ mates, for example 35. Qe4 Nd3+ 36. Kd1 Rf1 and mate. Similar mates occur on other interpositions on e4. And 34. Kg1?? Qxh2 is also mate. So white must accept: 34. Kxf2 Qxh2+ 35. Ke3 Qe5+ 36. Qe4 Nbc2+ 37. Kd3 Nb4+ and let’s catch our breath here for another analysis diagram. We’re almost at the end of this incredible trail.

vic_nb4.png

Position after 37…Nb4+ (Analysis)

What a fantastic position! Both sides have been ignoring each other for many moves and somehow equal chances are the result. Now we have two lines. In one, 38. Ke3 Nbc2+ 39. Kf2 Qh2+ with an amazing perpetual, or the hara-kiri attempt 38. Kc3?? Ne2 double check 39. Kxb4 Qc5+ 40. Ka4 Qa5 mate! Such a high intensity of tactics for so long! Note also, of course, 38. Kc4?? Qc5 mates immediately.

Let’s go back to the start of this analysis possibility after 19. Qh5. The best sequence for black is 19…Rxe5! 20. Rxe5 g6! (20…Nc6?? 21. Rd5! Qxd5 22. Nh6+ uncovering queen on queen attack) 21. Qh6! Qxd4! (21…Nc6 22. Rd5! Nxd4! 23. Rxd8+ Rxd8 24. Nxd4 Rxd4 should win for black, but it’s scary in G/1) 22. Nxd4 Bxe5 (this queen sac is actually good for black but pitfalls remain) 23. Nf5!! and now not 23…Bxa1?? and this greedy move is dramatically punished: 24. Ne7+ Kh8 25. Nxg6+! fxg6 26. Bxg6 and white mates with very little material left! The final nail in the coffin would be 23…Re8! and black does in fact win after 24. d4 Bxd4 due to back rank problems, but in G/1 the reader can clearly see how insane this all is. The complications exceed a dozen “normal games” and it’s anyone’s guess what would happen in mutual time trouble.

The game concluded prosaically with black retaining the extra piece while simplifying.

18…Rxe5 19. Rxe5 Bxe5 20. a3 h5! 21. Nh6+ Kf8 22. Qf5 Qf6 23. axb4 gxh6 24. Qxf6 Bxf6 25. f3 h4 26. Be4 Bxe4 27. fxe4 Be5 0-1

The behind the scenes variations were really quite astounding!

Here’s Round 2 vs GM Ildar Ibragimov.

GM Ildar Ibragimov – IM Mark Ginsburg, Continental Open Round 2

Gruenfeld Defense, 4. h4!? sideline

1. d4 Nf6 2. c4 g6 3. Nc3 d5 I don’t normally play the Gruenfeld but if I knew in advance my opponent would play a sideline, I would definitely try it more often. The only way to kill the beast, I think, is 4. cxd5. Or, white can try to bore black to death with 4. Nf3.

4. h4!?

ibrag_1.png

4…c6! A solid and good response to white’s impertinent sideline that was actually featured in a recent NIC “SOS” booklet.

5. cxd5 cxd5 6. Bf4 Bg7 7. e3 Nc6 8.Nf3

Believe it or not, Manuel Bosboom tried the crazy 8. h5?!! here versus Ivan Sokolov, Leewarden 1997. That game continued 8…O-O (black declines, why?) 9. hxg6 hxg6 10. Nf3 with some white edge, although he was outplayed by the strong GM playing black. If 8…Nxh5 9. Bh2, white has some nebulous compensation but it hardly looks enough.

8…O-O 9. Bd3 Bf5! 10. Bxf5 gxf5 Black has completely equalized.

11. Qb3 Qd7 12. Rc1 e6 13. h5 Ne4 14. h6 Bf6 15.Nxe4?! Black had no problems, but this move actually gives black a plus. Better would be 15. Rc2 or 15. Ne2 or even 15. O-O waiting.

15…fxe4 16. Ne5 This is the first critical moment of the game. How does black remove the knight?

ibrag_2.png

16…Nxe5? Completely strategically wrong! Much stronger was 16… Bxe5 17. dxe5 f6! (underestimated by me) 18. exf6 Rxf6 19. Bg3 Raf8 and black has an obvious edge. 17. Bxe5 Bxe5 18. dxe5 f6! is also good for black. The text gives white a simple to play space advantage and is a really weak choice in light of the strength of the other recapture.

17. dxe5 Be7 18. O-O Rac8 19. f3 exf3 20. Rxc8 Qxc8 21. Rxf3 Kh8 22. Rg3 Rg8 23. Rxg8+ Kxg8 24. e4! Fortunately black can survive this strong shot although he is definitely worse.

24…Kf8 25. exd5 Qc5+ 26. Kh2 Qxd5 27. Qc2 Bg5! A tactical trick to stay afloat despite white’s annoying threats against the h7 pawn.

ibrag_3.png

28. Qc8+ Of course, 28. Bxg5? Qxe5+! picks up the bishop next.

28…Qd8 29. Qc5+ Qe7 30. Qe3 Bxf4+ 31. Qxf4 Ke8 32. Kh3 Qf8 33. Qf6? 33. b4! keeps an edge. The text lets black’s queen get active and I escape.

33…Qc5 34. Qh8+ Ke7 35. Qxh7 Qe3+! An important intermediary move to soften up white’s king position before munching on e5. The game is now clearly drawn.

36. g3 Qxe5 37. Qg7 Qh5+ With a simple perpetual. Agreed drawn. A lucky escape and my first draw vs Ildar after two prior reverses.

1/2-1/2
