White finds a stunning knockout amidst the flurry of punches.

White's pieces are ideally poised for an attack, and this brilliant stroke not only allows Bd2 to contribute, but also gives White lots of options for breaking the pawn wall around the enemy K. 23... hxg6 There is no defense.

The final mistake, but White's position is still difficult after 28. Rxd4 Rdc8 29. Rc3 Rxc6 30. Rxa3 Rc1+ 31. Kg2 R8c2 and White probably won't be keeping his extra pawn for long. 28... Nxb5 29.

After the text, Black should play ...e5 and trade off the backward pawn while he has the chance. 13... Nd8?! 14. b4 Nf7 15. Bb2 Bd6 16. Ne5 Bxe5? This move only helps White: he gets the d4 square, and Black's good Bishop is gone. 16... Nd7 allows Black to play on. 17. dxe5 Ng4 18. Bd4 Qc7 19. Rc1 Qb8 19... Qd8 avoids clogging the development of the Qside. 20. f4 Ngh6 21. Ng3 21. Bc5 Rd8 22. Qc2 wins a pawn on the Kside, because 22... g6? 23. Bxg6 hxg6 24. Qxg6+ Kh8 25. Be7 forces mate. 21... b6 22.

Black doesn't even have a way to trade Queens. 28... Qb7 29. Qd6 Qf7 30. Rc7 . 28... Rg8? If Black wishe s to continue playing, he should get the hyperactive wQ off the board. rqb3rk/p1Q4p/1p2p3/3pPp1P/1P1B1Pn1/P2B2R1/6P1/2R3K1 w - - 029 29. Rxg4! Rxg4 30. Qd8+ Rg8 30...

White takes full advantage of Black's weakened Kside.

Giving up co ntrol of the dark squares is one sure way to lose, but Black is almost out of options anyhow. 14... hxg5? 15. fxg5 leads to trouble, no matter how Black plays: 15... Nh7 (15... Nxe5 16. dxe5 Qxe3+ 17. Kh1 Bxe5 18. Rf3 wins a piece for 2P) (15... Bxe5 16. gxf6! followed by Qg4 and maybe Bxg6) 16. Nxg6! fxg6 17. Bxg6 and White has a deadly attack. 14... Nh7 15. gxh6 Ndf6 is the best practical chance. 15. fxe5 hxg5 16. Bxg5 Nh7 17. Bh6 Bb7 17... Re8 18. Qg4 Ndf8 19. h4 and White will eventually crack g6 open. 18. Qg4 Kh8 19. Bxf8 Rxf8 20.

Black wastes time with the Q and N while the other pieces lie dormant, and is duly punished.

Ne3 Qg6 14. d5 Nb8? It would be better to trade this piece and accept doubled pawns rather than move it out of play. 14... Ne5 15.

O-O 21. Qf3? 21. Nxd7 Kxd7 22. Qf3 keeps the enemy K in the center. White has counterplay with the ideas of axb5-Ra7, Nb3(x)c5 and Qxd5. 21... Qe6 21...

Black will not be able to win the battle for d5, so he should play 14... a6 immediately. 15. Nc3 a6 16. a4 Bf5 16... Kh8 and ...f5 is an alternative, trying to use the Kside pawn majority. 17.

Why bother saving this tall pawn? wNe4 is a far superior piece - Black should be thrilled if White trades it. 20. Rd2 The time is ripe for 20. d6! Black can't take c6 due to the Bd5 skewer, and is faced with the threat of c7. 20... Bxe4? is not the way out: 21. d7 Qxc6 22. fxe4 focuses too much firepower on f7. 22...
