2016


1. e4 d6 2. d4 Nf6 3. Nc3 g6 4. f4 Bg7 5. h3 O-O 5... Nh5 is preferred by nearly 1K visitors to the ChessBase Common Analysis function. 6. Nf3 Ng3 7. Rg1 Nxf1 6. Nf3 c5 7. Be3 Allowing a transposition to a Sicilian Dragon structure with White playing the tempo wasting h3. 7. dxc5 Qa5 8. cxd6 Nxe4 9. dxe7 Bxc3+ 10. bxc3 Re8 11. Bd3 Qxc3+ 12. Bd2 Nxd2 13. Nxd2 Qd4 (13... Rxe7+ 14. Kf2) 14. g3 Rxe7+ 15. Kf1 Nc6 7... cxd4 8. Nxd4 8. Bxd4 Nc6 gains time by attacking the bishop. 8... Nc6 8... Qb6 was analysed and is better for Black but the lines are complex and messy eg. 9. Nf5 (9. Rb1 Nxe4 (9... Nc6 10. Nf5 Qa5 11. Nxg7 Nxe4 12. Nh5 gxh5 13. b4) 10. Nxe4 e5 11. Nf5 Qb4+ 12. Qd2 Qxd2+ 13. Bxd2 Bxf5 14. Nxd6) 9... Qxb2 10. Nxe7+ Kh8 11. Bd4 Nxe4 12. Bxg7+ Kxg7 13. Nxe4 Qb4+ 14. Kf2 Qxe4 15. Qxd6 9. Bd3 Bd7 10. Qd2 10. g4 Qb6 is winning now 11. Nf5 (11. Nce2 Qxb2 12. Rb1 Qa3 13. Rxb7 Rab8) 11... Qxb2 10... a6 11. O-O-O 11. Nf3 Rc8 12. O-O is safest but White has nothing from the opening and Black can commence standard queens-side play with b5/Na5/ Nc4. 11... b5 12. Nxc6?! 12. Kb1= 12... Bxc6 now Black has pressure on e4 and the b-file to work with. 13. a3 Qb8 14. f5? 14. Bd4 neutralising the bishop is the only hope but Black is far better-now White is lost after 14.f5. 14... b4 14... a5 is also good but not quite as strong for instance 15. Nd5 (15. Bh6 b4 16. Bxg7 Kxg7 17. Nb1 Rc8 18. Rde1 Bb5 19. Rhf1 Bxd3 20. Qxd3 Ra7 21. fxg6 hxg6 22. Rf2 Rac7) 15... Qb7 (15... Nxd5 16. exd5 Bxd5 17. fxg6 hxg6 18. Bxg6=) (15... Bxd5 16. exd5 Nxd5 17. Bh6 Nf6 18. fxg6 hxg6 (18... fxg6 19. h4=) 19. h4) 15. axb4 Qxb4 16. Nb1 16. e5 Rab8 17. b3 Nd5 18. Nxd5 Qa3+ 19. Kb1 Bxd5 16. Bh6 Rab8 16. Na2 Qa4 16... Qb7 17. c3 17. fxg6 Nxe4 17... Bxe4 18. fxg6 hxg6 19. Bh6 Bxd3 winning a second pawn. Another way was to continue the attack with 19... Bxh6 20. Qxh6 Rab8 21. b4 Rfc8 with overwhelming threats. 20. Bxg7 Kxg7 21. Qxd3 Qxg2 22. Rhe1 Rab8 23. Rd2 Qb7 24. Qe2 Rfe8 25. Qf2 Black now has to play very accurately to win as White to his credit finds some strong threats. 25... Qb6 26. Qf3 Qc5 27. Rc2 Qg5+ 28. Nd2 d5 29. Kb1 e5 30. Qd3 Re6 31. Nf3 Qf4 32. Qe2 Rbe8 33. Rf1 Qc4 34. Qf2 Qc7 34... Ne4 was playable but there is no need to risk the complications. 35. Nxe5 Rxe5 36. Qxf7+ Kh6 37. Qf4+ Ng5 35. Ng5 Rc6 36. Qh4 Rh8 37. Qg3 e4 38. Qe3 Qe5 39. Rcf2 Rh5 40. h4 Rxh4 At last clarifying the position. 41. Nf3 Qf4 42. Qd4 exf3 0-1 [M.J.Donnelly]
