Analysed by Centaur (Hairulov+Fritz)

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f3 O-O 6. Nge2 c6 7. Be3 a6 8. a4 a5 9. g4!?

White shows that he is in aggressive mood. He will push his kingside pawns towards black's kingside - ala Sicilian Dragon Yugoslav Attack.9... Na6 10. Ng3 Nb4 A strategic square for black's knight. Now white have to think twice if he want  to castle queenside. 11. Qd2 e5 12. d5 Qe7 13. Be2 Nd7 14. h4 Nc5 15. Ra3

This shows that white is not planning to castle kingside. The rook lift to a3 has one hidden agenda. Usually white will swing the rook to the kingside to support his attack later. 15...cxd5 16. Nxd5 Nxd5 17. cxd5 Bd7 18. Bd1 f5 Black shows that he can be aggressive too but probably black's should not open  lines towards his kingside. 18... Rfc8!? is a viable option 19. gxf5 gxf5

20. Bg5 ?! White miss chance to gain a strong initiative with 20. Nxf5 Bxf5 21. exf5 Rxf5 22. Bc2 20... Qf7 21. Rg1 Kh8 21... f4! 22. Nf5 Bxf5 23. exf5 Kh8!  and now white will have problem with his bishop on g5 and pawn on f5. 22. h5 ?! 22. exf5!? Bxf5 23. Nxf5 Qxf5 24. Be7 with double edge position. 22...
f4 23. h6 White try to confuse matter. 23...Bf6  24. Nf5 Bxf5 25. exf5 Rg8 26. Bxf6+ Qxf6 27. Rh1 White problem is he can't used his other rook on a3 to joint the attack.Now black is controlling the g-file. 27...Qxf5 27... Rg3! is also strong. 28. Bc2 Qg5 29. Qf2 Qg2  Black can give more headache to white by attacking the queenside with  29... Ra6 followed by Rb6-attacking the b2 pawn. 30. Rh2 Qg1+ 31. Kd2 31. Qxg1 Rxg1+ 32. Kf2 Rag8  31... Qxf2+ 32. Rxf2 Rg3 33. Rc3 Rh3  White's h6 pawn is doom. 34. Rxc5 White realized that  he cant just wait and watch black improving his position so he try his luck with this sacrifice which create a passed pawn. 34...dxc5

35. Kd3 Rxh6 36. Kc4 b6 37. Kb5 Rd8 38. Be4 Rdd6 39. Rg2 Rh5 40. b3 ?! maybe white should consider 40. Ka6  with the idea of Kb7 and Kc7 later to support white passed pawn. 40... h6 41. Rg6 Rxg6 42. Bxg6 Rg5 43. Bd3 Kg7 44. Kxb6 Kf6 45. d6 Rg7 45... h5 makes it even easier for Black 46. Kc7 Rg8 47. d7 Ke7 46. Kc6 h5 47. d7 47. Bc4 a fruitless try to alter the course of the game  47...Rg1 48. Kc7 Rd1 49. d7 Ke7 47... Rg8 48. Kc7 Ke7 49. Bf5 Rd8 50. Bh3 h4 51. Bf5 e4!  Black create another passed ( f-pawn).

52. fxe4 f3 53. Bh3 f2 54. Kc6 Rxd7 55.Kxc5 Of course 55. Bxd7 and black queening f1=Q  55... Rd3 0-1  White  resign because he cant stop black from queening. for e.g 55... Rd3 56. Bg2 h3 57. Bf1 Rxb3 58. Bc4 Rb4 59. e5 h2 win.
