[Event "Niksic"] [Site "?"] [Round "0"] [White "Kasparov"] [Black "Portisch"] [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 d5 6. cxd5 Nxd5 { This, though more fashionable, is hardly better than 6...cxd5.} 7. e3 Nxc3 8. bxc3 Be7 9. Bb5+ c6 10. Bd3 c5 11. O-O Nc6 12. Bb2 { Before advancing with pawn e4 White improves the stationing of his pieces.} 12... Rc8 13. Qe2 O-O 14. Rad1 Qc7 { 14...h6 15.dxc5 Bxc5 allows White to win material.} 15. c4 {This completely transforms the nature of the game. There is a threat for White's d-pawn to advance and to be backed up by e4; additionally the White bishops can rake Black's king's position.} 15... cxd4 { 15...Bf6 16.d5 Ne5 17.Nxe5 Bxe5 when White can win material.} 16. exd4 Na5 17. d5 {All White's pieces spring into action; Black's plan to tie White down to defense in the center proves futile.} 17... exd5 {17...Nxc4 18.Qe4 g6 19.Bxc4 Qxc4 20.Qe5 f6 21.Qxe6+ Rf7 22.Rc1 Qa6 23.Nd4 when Black's pieces have been pushed to the side of the b} 18. cxd5 Bxd5 {Black's king appears safe but White's following play does away with that illusion. Can you find the killer move?} 19. Bxh7+ Kxh7 20. Rxd5 Kg8 {Now, though White's pieces are ideally poised, there's nothing that is obviously decisive. Until it dawned on me... what else? Yes! Yes! That's it. Sacrifice again!} 21. Bxg7 {This piece e is positional in nature. It enables White to centralize his rook and knight and they, together with the queen, will make up aformidable team to attack the exposed Black king.} 21... Kxg7 22. Ne5 {An astonishing state of affairs. White has no direct threats. His pieces have no grip. Despite this Portisch chooses the only way that does not lose immediately.} 22... Rfd8 {22...f5 23. Rd7 Qc5 24.Nd3 Takes advantage of the pin on the seventh rank 22...Qc2 23.Qg4+ Kh7 24.Rd3 Rc6 25.Qf5+ Kg7 allows White to win material.} 23. Qg4+ Kf8 24. Qf5 f6 {This further weakening is practically forced. 24...Bd6 25.Qf6 Kg8 26.Qg5+ Kf8 27.Qh6+ Kg8 28.Ng4 With numerous mate threats.} 25. Nd7+ Rxd7 { 25...Kg7 26.Rd4 leaves Black defenseless against White's intended 27.Rg4+.} 26. Rxd7 Qc5 27. Qh7 Rc7 28. Qh8+ {28.Rd3 would allow the pretty..Qxf2+ 29.Kxf2 Bc5+ 30.Kg3 Rxh7 when Black has escaped.} 28... Kf7 29. Rd3 Nc4 30. Rfd1 Ne5 { A mistake which only hastens the end. 30...Bd6 31.h4 The advance of this pawn combined with the threats to the Black king continue to give White a big advantage.} 31. Qh7+ Ke6 32. Qg8+ Kf5 33. g4+ Kf4 34. Rd4+ Kf3 35. Qb3+ { This game was later awarded the USSR Sports Committee prize for the supreme creative achievement of 1983.} 1-0
