  An Englishman: Good Evening: I thought Black was winning for most of the game, but now I doubt my original judgment. After 21.Re1, it becomes clear that Black's Queen side pieces don't play any particularly useful roles in the game.
Aug-26-09  Primoman: It seems like 30...Qe6 is a major blunder. Why not 30...Qd8 to protect the pawn and better fortify blacks position?

Aug-26-09  JamesMazur2: In response to OneArmedScissor, if 25...Qxg4 is played, White can respond 26. Nd5, attacking the c7 pawn. This causes problems for Black, so the actual move 25...Ne7 is played to avoid this line.

  Once: <Jim Bartle> Thanks - that explains it!
Aug-26-09  JamesMazur2: In response to Primoman, if 30...Qd8 is played, White can respond 31. Qa1+.

Black then has 7 possible responses:

31...Qf6 32. Qxf6+ and Black loses.

31...Nd4. White can play either 32. Qxd4+ or 32. Nxd4, winning the knight for free.

31...Kg8 32. Nf6+ with a strong attack on Black's king.

31...Kh7 32. Nf6+ also with a strong attack on Black's king.

31...Kh6 32. g5+ also allows White to directly attack Black's king.

31...f6 32. g5 and White will soon play gxf6 as the pawn on f6 is pinned by the queen. White has won a pawn and will eventually be able to break up the defenses on Black's kingside. An example line is 32...Ne5 33. gxf6+ Rxf6 34. Nxe5 dxe5 35. Qxe5 and the rook is pinned as well as attacked by the knight. Eventually Black will be forced to exchange a rook for a knight, and White is ahead a pawn, whose promotion can be forced.

This leaves 31...Ne5. First, 32. g5. Black has a few possible responses:

32...Rb6. White has 33. Nxe5 dxe5 34. Qxe5+ f6 35. Nxf6 Rbxf6 36. gxf6+ Qxf6 37. Qxf6+. 37...Rxf6 but White is still up a pawn and will eventually promote.

Black could also try to avoid 33. Nxe5.

32...f6 leads to complications similar to those in the position after 31...f6, as explained above.

32...Qe8 allows for 33. Nxc7, and White wins a pawn.

32...Re8 33. Nd4! The knight on e5 still can't move. It will either be captured for free on f3 or 34. Nf5+! and 35. Qg7#. White is threatening f4 to win the knight, so Black must aim to gain as much compensation as possible: 33...Qxg5 34. f4. 34...Qh5 discourages 35. fxe5, but White can still make that move without fear: 35...Qxe5 36. Qd1 is one possible line. Nxc7 is White's threat, and in defending that threat, Black will further weaken his position, to the point where White can win. However, 35. Nc6! is even stronger. It prevents ...Qxe5 and ...Rxe5 after fxe5 is played.

In conclusion, the move 30...Qe6 avoids these lines. White can still win in this variation by 31. Ng5 (as opposed to putting the pawn on g5 in the Qd8 variations). Amazingly, however, White actually played 31. Nxc7? and Black could have drawn the game with 31...Qd7 but made his own blunder with 31...Qxg4 and White won with 32. Qxd6! It just goes to show that humans under pressure will often not make the best move. So, in one sentence this whole essay:

If 30...Qd8 is played, White will respond 31. Qa1+! and win.

P.S. 31. Qa1+ is still somewhat effective after the actual 30...Qe6. Try it yourself!

  YouRang: A pretty desperate pun today, IMO. The only connection to the game, as far as I can tell, is "Chuk".

<Jim Bartle> is correct: Chuck E. Cheese is a restaurant chain aimed at young children, serving pizza with a variety of little coin-operated game and ride machines.

Very noisy! No sane adults go there to dine, and if they did, they wouldn't be sane when they left.

  eternaloptimist: <YouRang: Very noisy! No sane adults go there to dine, and if they did, they wouldn't be sane when they left.> lol :D Yes, I agree YouRang. Also, if u bring kids in there, it's difficult to get them out of there. They love that place. <WhiteRook48: check every check and capture> That's great advice. I learned that from a guy who used to be a teacher @ The University of Southern Mississippi. He used to play in chess trnts. & was 1 of the guys in charge of the chess club there. I used that advice ever since he told me that way back in the late 1980s. Which book did that axiom come out of anyway?

  LoveThatJoker: <OneArmedScissor: Why not 25...Qxg4?>

Hi OneArmedScissor, I used Fritz 11 to analyze these lines and this is what came up after 25...Qxg4

25... Qxg4 Fritz 11: 26. Nd5 h3 27. g3 Rac8 28. Kh2 Rfe8 29. Qc3 Kh7 30. Nf3 Re6 31. Nf4 Rf6 32. Nxh3 Rb8 33. Nfg5+ Kg7 34. f3 Qh5 35. e5 dxe5 36. Rxe5 Qh8 37. Kg2 Rd8 38. Ne4 Kf8 39. Nhf2 Qh7

(39... Re6 40. Rd5 Qxc3 41. Rxd8+ Ke7 42. Rd7+ Ke8 43. Nxc3 Rxc6 44. Rd3; 39... Rf5 40. Re8+)

40. Qc5+ Kg7 41. Nxf6 Nxf6 42. Re7 Rh8 43. Qe5 Qh2+ 44. Kf1 Qh5 45. Qxc7

Nov-09-09  Plato: <meth0dSNK: you guys are all nubz.. grischuks first mistake was 9. Nh5>

<meth0dSNK: 9... Ne8 is better for Grischuk.>

Nope. Grischuk's move 9...Na5 is the main line, having been played in nearly 3000 games between masters or better. It's been played twice by Kasparov himself, not to mention Topalov, Ivanchuk, Radjabov, Ponomariov, Shirov, Gelfand... the list goes on.

9...Ne8, by contrast, ,has never been played by a 2700+ player. It was played once by Radjabov when he was still 2680. It also scores worse for Black, statistically.

Why? 9...Nh5 exerts pressure on the f4 square and the knight will want to go there in many lines. From e8 the knight does nothing.

<meth0dSNK> I know how you claim you're playing at a high 2700 level and all, but anyway, hopefully this helps you get your rating to 2000.
