[Event "Moscow"] [Site "?"] [Round "0"] [White "Kasparov"] [Black "Murey"] [Result "1-0"] [ECO "E12"] [Opening "Queen's Indian: 4.Nc3 Bb7"] 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. Nc3 Bb7 5. a3 {The Petrosian system of the Queen's Indian Defense has brought me many victories.} 5... d5 6. cxd5 Nxd5 { A continuation which has been becoming more popular recently. It is difficult to explain why Black should give up the center without a fight, but perhaps good practical results are the reason why.} 7. Qc2 {At the time of this game this was a new twist to the position. White had usually played 7.e3. The idea of 7.Qc2 is to play e4 in one move instead of two.} 7... c5 8. e4 Nxc3 9. bxc3 Nc6 10. Bb2 {Simple and strong! The pawn is well protected and the rook is ready to occupy the d1 square.} 10... Rc8 {Natural but bad. Black will not be able to take advantage of the position of the White queen, while the loss of a tempo will cost him dearly. It was necessary to play 10...Be7, preparing to castle.} 11. Rd1 cxd4 12. cxd4 a6 {Played to keep White's bishop off the a4-e8 diagonal. 12...Nxd4 allows White to win material. 12... Ne5, trying to take advantage of White's queen being on the c-file, would backfire after...13.Bb5+ Bc6 when White can win material.} 13. Qd2 {Now the cou nterchances connected with the pressure on the c-file are prevented and the d-pawn threatens to advance to d7. In order to thwart d5 Black would have to play Ne7, but what sort of position is that?} 13... Na5 {Understanding that the strategic struggle has been lost, Black is trying to find some tactical resources, but in vain - chess justice is on White's side.} 14. d5 exd5 {14...Nc4 15.Bxc4 Rxc4 16.O-O is much better for White because of his lead in development.} 15. exd5 Bd6 {15...Qe7+ 16.Be2 Nc4 17.d6 Nxd6 18.O-O is winning for White since Black's king is stuck in the center.} 16. Bxg7 Qe7+ 17. Be2 Rg8 18. Qh6 { Now the main drawback of the Black position is visible. His pieces cannot join in the fight quickly, and his king is left to defend himself.} 18... f5 19. Bf6 Qf8 20. Qxh7 Qf7 { 20...Rxg2 21.Ne5 With the deadly threat of 22.Bh5+ is winning for White.} 21. Qxf5 {The rest is a matter of artistic interpretation.} 21... Rg6 22. Qe4+ Kf8 23. Ng5 Rxg5 24. Bxg5 Re8 25. Bh6+ Kg8 26. Qg4+ { Black resigned because of his material deficit.} 1-0
