Move

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qc2 O-O 5. a3 Bxc3+ 6. Qxc3 b6 7. Bg5 Bb7 8. e3 d6 9. f3 Nbd7 10. Bd3 h6 11. Bh4 c5 12. Ne2 Rc8 13. b4
   A rare, yet possible move, invented by GM Sorokin and employed by GM Ivan Sokolov.
cxd4?!
   Better was 13...d5.
14. exd4 Re8?!
   It is not easy to suggest a good plan for Black, but this move is certainly dubious.
15. O-O e5 16. Rac1
   This is very solid; also interesting was 16 Bf5!?.
e4
    Consistent, but risky.
17. fxe4 g5
   After 17...Bxe4 I was going to play 18 Ng3 Bxd3 19 Qxd3 and if here Black dares to trap the bishop - 19...g5, he might run into the following possible line: 20 Nf5 gxh4 21 Nxh6+ Kf8 22 Qh7!.
18. Bg3 Nxe4 19. Bxe4 Bxe4 20. Bxd6 Bxg2 21. Ng3!
   This move brought be one of the rewards for 'best attack' in the tournament. I rarely sacrifice any material and so after the game I said that I had just forgotten about the rook on f1! :-) But speaking seriously, the text is best way to exploit Black's risky strategy. This sacrifice does not win by force, but once the white knight appears on f5, Black's king will feel very uncomfortable. Besides, it's much more difficult to defend than to attack.
Bxf1 22. Rxf1 Re6?
   Instead of this move computer suggests 22...g4!? - something which I did not consider during the game at all. Perhaps, we, poor human beings, have some kind of a mental block sometimes. This move weakens the kingside furthermore, but it vacates the g5-square for the black queen, which is a good defensive idea. Here White would have to work much harder than in the game in order to prove his advantage. However, I believe that after 23 Nf5 Qg5 24 Qc2! h5 25 c5 bxc5 26 bxc5 White is better, as his pawns are very dangerous.
23. Nf5 Kh8
   This move looks very strange, but it was necessary, as otherwise 24 d5 would be absolutely devastating. Yet, Black's defence has a weak spot...
24. d5+ Qf6 25. Nd4 Rxd6 26. Rxf6 Rxf6 27. Nf5!
   the knight once again paralyses Black's kingside, not giving him a chance to consolidate his position.
Kh7 28. Qc2 Kh8 29. Qe4
   White threatens to play 30 Qe7, so Black resigned. His position is indeed hopeless, although he could have played a bit longer with 29...Ra8.
