[Event "Lucerne Olympiad"] [Site "?"] [Round "0"] [White "Kasparov"] [Black "Nunn"] [Result "1-0"] [ECO "E00"] [Opening "Queen's Pawn: Neo-Indian, 3...c5"] 1. d4 Nf6 2. c4 e6 3. Nc3 c5 {John Nunn is a famous theoretician who loves sharp openings. In this game we "discuss" the main line of the Modern Benoni Defense.} 4. d5 exd5 5. cxd5 d6 6. e4 g6 7. f4 {White takes control of the e5-square, which is often home to a Black knight in other variations.} 7... Bg7 8. Bb5+ Nfd7 9. a4 {Now castling would be sensible, but Nunn had prepared something else. Since the advance of the a-pawn to a6 often makes it difficult to bring the knight into the game from b8, Nunn develops it immediately.} 9... Na6 10. Nf3 Nb4 11. O-O a6 {Consistent, but this turns out to be a serious error because I can attack immediately. True, not all of my pieces are in the game, but on the other hand Black's pieces are all in awkward positions.} 12. Bxd7+ Bxd7 13. f5 O-O 14. Bg5 { Now my pieces are developed and a fierce attack begins.} 14... f6 {14...Bf6 15. Qd2 14...Bd4+ 15.Kh1 f6 16.Bh6 Re8 17.Rc1 I would have a much better position.} 15. Bf4 gxf5 {A mistake, which hastens the end. 15...Qe7 16.fxg6 hxg6 17. Nh4 Kh7 18.Bg3 Black is still in deep trouble.} 16. Bxd6 Bxa4 {16...Re8 1 7.Bxc5 fxe4 18.Nd4 Nd3 19.Nxe4 Rxe4 20.Qxd3 f5 21.Qg3 Kh8 22.Nxf5 Bxb2 23.Nh6 The weakness at f7 is fatal.} 17. Rxa4 Qxd6 18. Nh4 fxe4 19. Nf5 { The occupation of this square signals the beginning of the end.} 19... Qd7 { 19...Qe5 20.Qg4 Rf7 21.Nh6+ Kf8 22.Nxf7 Kxf7 23.Qxe4} 20. Nxe4 Kh8 { After 20...Rae8 21.Qg4 Rxe4 I can win Black's queen 22.Nh6+ Kh8 23.Qxd7} 21. Nxc5 {Nunn resigned. A series of exchanges on d5 leaves Black in a hopeless position .} 21... Qxd5 22. Qxd5 Nxd5 23. Ne6 Rf7 24. Nfxg7 Rxg7 25. Nxg7 Kxg7 26. Rd4 1-0
