[Event "World Junior Championship"] [Site "?"] [Round "0"] [White "Kasparov"] [Black "Fedorowicz"] [Result "1-0"] [ECO "E12"] [Opening "Queen's Indian: Petrosian, 4...c5"] 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. a3 { This is the Petrosian variation of the Queen's Indian Defense.} 4... c5 5. d5 Ba6 6. Qc2 exd5 7. cxd5 g6 {Black adopts one of the sharpest continuations in response to the Petrosian System.} 8. Nc3 Bg7 9. g3 O-O 10. Bg2 d6 11. O-O Re8 12. Re1 Qc7 {A new idea at the time this game was played. It turns out that Fedorowicz had already played this move in the 1981 USA championship but I was unaware of this.} 13. Bf4 {Trying to take advantage of Black's queen by the indirect attack on the h2-b8 diagonal.} 13... Nh5 14. Bd2 Nd7 15. Qa4 { 15.a4 is the thematic continuation holding back Black's queenside play. However, after ...c4 I saw no clear way to improve my position.} 15... Bb7 16. Qh4 {Although no immediate attack is associated with this move. The idea is to attack on the queenside first diverting the Black pieces away from the protection of the king.} 16... a6 17. Rac1 b5 18. b4 { The point of White's plan. In this way he jams his opponent's operation.} 18... Qd8 {18...cxb4 would allow White to win material due to the discovered attack on the c-file.} 19. Bg5 f6 20. Bd2 f5 {In this way the e4 is under Black's control and the Nh5 is marked for central activity.} 21. Bg5 Qb6 { 21...Bf6 With the idea of exchanging off pieces should be preferred.} 22. e4 cxb4 23. axb4 Rac8 {The critical position. Both sides have achieved what they have been striving towards, maximally activating "their own" areas of the board.} 24. Be3 Qd8 25. Bg5 Qb6 {This move was made quickly, and it was clear that my opponent had no objection to a draw by repetition. Contemplating the position, I detected that there were some hidden combinational possibilities.} 26. exf5 {This move carries with it a piece sacrifice. White will not obtain any immediate gain. But there are all sorts of little things amiss in Black's position of his queen, like the Bb7 and the Nh5, which weaken their king's cover.} 26... Rxe1+ 27. Rxe1 Bxc3 28. Re7 Rc4 29. Qh3 {A simple an d strong answer: the queen lies in ambush. Her transfer from the queenside has proved most successful!} 29... Bc8 30. fxg6 Ndf6 { 30...hxg6 31.Qe6+ Kh8 allows White a mating attack.} 31. Bxf6 Nxf6 32. gxh7+ Kf8 33. h8=Q+ Kxe7 34. Qg7+ { Black resigned because the two queens will easily take care of his king.} 1-0
