1. d4 Nf6 2. c4 c5 3. d5 e6 4. Nc3 exd5 5. cxd5 d6 6. e4 g6 7. h3 Bg7 8. Nf3 O-O 9. Bd3 b5 10. Bxb5 Nxe4 11. Nxe4 Qa5+ 12. Nfd2 Qxb5 13. Nxd6 Qd3 14. N2c4 Qxd1+ 15. Kxd1 Ba6 16. Bg5 Nd7 17. Kc2 Nf6 18. Rad1 Rfd8 19. b3 h6 20. Bh4 Bxc4 21. Nxc4 g5 22. Bg3 Nxd5 23. a3 Bd4 24. h4 Nc3 25. Rde1 Re8 26. Nd6 Re2+ 27. Kd3 Rb2 28. hxg5 Rxb3?! A risky move which unfortunately not being punish by Mas.

29. Kc4 Stronger is 29. gxh6! Nb1+ (29... Kh7 30. Re7) 30. Ke4 Nxa3 31. h7+ Kg7 32. Nf5+ Kh8 33. Nxd4 29... Rxa3 30. gxh6 Kh7 31. Re7 31. Nxf7! is stronger. For e.g 31...Ra4+ 32. Kd3 Ra3 33. Ng5+ Kg6 34. Ne6 Nd1+ 35. Kc4 Nxf2 36. Bxf2 Bxf2 37. Ref1 31... Ra4+ 32. Kd3 Nd5 33. Rxf7+ Kg6 34. Rb7 Rh8 35. h7 Bg7 36. Rxg7+ My new love Sillicon Master - Rybka 3 gave 36. Nc4! Nb4+ (36... Rxh7 37. Rxh7 Kxh7 38. Be5) 37. Ke4 Nc6 38. Rc7 Rxc4+ 39. Kd5 Rd4+ 40. Kxc6 Bf6 (40... Rc4 ?? 41. Rxg7+ Kxg7 42. Be5+) 36... Kxg7 37. Be5+ Nf6

38. Ne8+? Mas lost all his advantage due to this move. He still have a significant advantage after 38. Rh5 c4+ 39. Ke2 Ra2+ 40. Kf3 Ra3+ 41. Kf4 c3 42. Ne4 c2 43. Bxf6+ Kg6 44. Rc5 38... Rxe8 39. h8=Q+ Rxh8 40. Bxf6+ Kxf6 41. Rxh8 Rd4+ 42. Ke3 42. Kc3 is another option but then white have problem to support his passed pawns with his king 42... a5 43. f4 Rb4 44. Rh6+ Kg7 45. Ra6 Rb3+ 46. Kf2 Probably Mas should try moving his king to play more active role with 46.Ke4!? but i'm not sure whether it's enough for a win 46... Rb5 47. Ke3 Rb3+ 48. Ke2 Rb5 49. g4 c4 50. Rc6 a4 51. Ra6 c3 52. Rxa4 Rc5 53. Kd1 c2+ 54. Kc1 Rc6 55. f5 Kf6 56. Ra7 Rc5 57. Ra6+ Kg7 58. Ra2 Rc4 = 59. g5 Rc5 60. Ra7+ Kg8 61. Ra8+ Kg7 62. f6+ Kg6 63. Rg8+ Kf7 64. Rg7+ Kf8 65. g6 Rc6 The triangular position ( Rg6-f6-g6) has been reached with the defender king infront. White can't win because his king who has it's own problem to stop black passed pawn can't help his own pawn to promote. 1/2-1/2
