1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Be2 O-O 6. Nf3 e5 7. O-O Nc6 8. d5 Ne7 9. Ne1 Nd7 10. Be3 f5 11. f3 f4 12. Bf2 g5 It's nice to see this old line again at top level. 13. Nd3 The most natural and oldest move in this position. 13... h5?! Was Radjabov confused here? In such positions, normally Black plays 13... Nf6 as soon as he can't prevent c4-c5 anymore. It's more flexible because sometimes Black doesn't need h7-h5. Apparently Radjabov decided that he can't do without ...h5 here, although theory suggests otherwise. The following classical game is still known to be the way to go for Black: 14. c5 Ng6 15. Rc1 Rf7 16. cxd6 cxd6 17. Rc2 Bf8 18. Qd2 g4 19. Rfc1 g3! 20. hxg3 fxg3 21. Bxg3 Nh5 22. Bh2 Be7 23. Nb1 Bd7 24. Qe1 Bg5 25. Nd2 Be3+ 26. Kh1 Qg5 27. Bf1 Raf8 28. Rd1 b5 29. a4 a6 30. axb5 axb5 31. Rc7 Rg7 32. Nb3 Nh4 33. Rc2 Bh3 34. Qe2 Nxg2 35. Bxg2 Bxg2+ 36. Qxg2 Qh4 37. Qxg7+ Kxg7 38. Rg2+ Kh8 39. Ne1 Nf4 40. Rg3 Bf2 41. Rg4 Qh3 42. Nd2 h5 43. Rg5 0-1, Taimanov-Najdorf, Candidates Tournament Zurich 1953 14. c5 Nf6 15. Rc1 g4!? Immediately making it a pawn sacrifice. Perhaps 15... a6 is best he re, in combination with 13...h5, although it does violate the rule not to move your pawns on the wing where your worse. 16. Nb5 Ne8 17. fxg4 a6 18. Nc3 hxg4 19. Bxg4 Nf6 20. Bxc8 Rxc8 21. g3!? 21. Qb3 also looks strong. 21... Qe8 22. Kh1 Qg6 23. Qe2 White is just a pawn up here. 23... f3 This little trick doesn't bring Black very much. 24. Qxf3 Nfxd5 25. Nxd5 Nxd5 26. Qe2 Nf6 27. Rce1 That's it. No real counterplay, a bad bishop on g7, pawn down - every King's Indian player's nightmare. 27... Qf7 28. g4 Qg6 29. h3 Rf7 30. Kg2 Nd7 31. Bg1 Qe6 32. b3 Rxf1 33. Rxf1 d5 34. g5 a5 35. h4 Qc6 36. Re1 Rf8 37. exd5 Qxd5+ 38. Qe4 And the worst thing is that it's so damn easy for White to play. 38... c6 39. Bh2 Qe6 40. Bg3 Rf5 41. a3 Rf7 42. b4 Qa2+?! 43. Re2 Qxa3 44. g6 Black resigned because 45.Qc4+ and 46.Ra2 traps his queen. A strong game by Shirov, who is now second in the standings, behind Anand. And Radjabov, well, it seems in this old variation he has to check his theory!? 1-0
