1. Nf3 d6 2. d4 Nf6 3. c4 g6 4. Nc3 Bg7 5. e4 O-O 6. Be2 e5 7. dxe5 Kings Indian - The Lazy Way. 7... dxe5 8. Qxd8 Rxd8 9. Bg5 c6 10. Nxe5 1:58 10... Re8 1:54 11. O-O-O Na6 11... Rxe5? 12. Rd8+ Re8 13. Bxf6+/- 12. Rd6 3 12... Nxe4 13. Nxe4 Bxe5 14. Nf6+ Bxf6 15. Bxf6+/= So far I knew the theory. White owns the bishop pair and has some play on the d-file and the dark squares. 15... Bf5 16. Kd2 20 - played after a long thought. Funny, see my comment below to move 17 of Black. 16. Rhd1?? Rxe2 17. Rd8+ Re8-+ I didn't like 16. Bf3 because of 16... Nb4 (16... Nc5 is also possible. 17. Rhd1 Be4~~) 17. a3 Nd3+ 18. Kd2 Nxf2 16... Nc5 17. f3 h5N The first new move in this game. 17... Re6 18. Rxe6 Bxe6 was played twice already, both games ended in a draw. 17... a5 18. g4? (18. Rd1!+/=) 18... Bxg4! 19. Bd4 Ne6 20. Bb6 Bf5 21. Re1 Mueller - Kuempers, 1/2-1/2 (54.) VEM 2009! But I only remembered this game very vaguely. At that time I also thought about 25 minutes on 16.Kd2. 18. Re1 15 18... Re6 19. Rxe6 Bxe6 20. Kc3 1:09 20... Nd7 1:31 21. Bh4 Kg7 22. Bd3 a6 23. a4 Re8 24. Bf2 f6 25. f4 f5 26. a5 Kf7 27. b4 Nf6 28. h3?! 10 - Perhaps not the best. 28...Ng4 isn't really a threat. 28... Rc8 I was more afraid of 28... Ne4+ 29. Bxe4 fxe4 30. Rxe4 Bf5 31. Re5 Rxe5 32. fxe5 Ke6 33. Kd4= 29. Bb6 Nd7 30. Rc1 15 - 0:09 30... Nf6?! 0:52 Why did I think so long? I feared 30... Nxb6 31. axb6 c5 32. bxc5 Rxc5 33. Kd4 Rc8 34. c5 Rd8+ 35. Ke3~~ or 30... c5 31. Be2 Nxb6 32. axb6 cxb4+ 33. Kxb4 Bd5!~~ 31. Kd4 Re8 32. Re1?! 32. b5! cxb5 33. cxb5 axb5 34. Bxb5+/- 32... Re7 33. Bc5 Rd7+ 34. Ke3 Ne4 35. Bd4?! Nd2! A strong move which I haven't seen. 36. Kxd2 Rxd4 37. Ke3 Rd7 38. Rc1 Kf6 39. Rc3?! 39. h4 39... g5 40. fxg5+ 0:03 40... Kxg5 0:18 41. h4+? 10 - Again one move after time control I blundered. 41. g3 h4 42. gxh4+ Kxh4 43. Kf4~~ 41... Kg4 41... Kxh4? 42. Kf4 Rg7 (42... Rd4+ 43. Ke5+-) 43. Bxf5 Bxf5 44. g3+ Kh3 45. g4+ Kg2 46. gxf5+/= The f-pawn looks more dangerous. 42. Be2+ Kxh4! Of course! 42... Kg3 43. Bf3 and here I also miscalculated some lines. 43... f4+ 44. Ke4 Bg4! 43. Bf3 43. Kf4 Rd4+ 44. Ke5?? Re4+-+ was my oversight. 43... Kg5 44. g3 Rh7 45. Rc1 10 45... h4 46. gxh4+ Rxh4 47. b5 Rh3 47... axb5 48. cxb5 cxb5 49. Bxb7~~ 47... Rxc4 48. bxa6! bxa6 (48... Rxc1?? 49. axb7 Rb1 50. a6+-) 49. Rxc4 Bxc4 50. Bxc6 f4+ 51. Kf2= 48. bxc6 5 The bots like 48. Rg1+ Kf6 49. Rh1! I missed this trade. 49... Rxh1 50. Bxh1 Bxc4 51. bxc6 bxc6 52. Bxc6= 48... bxc6 49. Kf2 c5 50. Bd5! 0:19 50. Bb7 Ra3 51. Bxa6 Rxa5 52. Bb5 Ra2+-+ 50... Kf6 0:45 50... Bxd5 51. cxd5 Ra3 52. Rxc5= 51. Re1! Bd7 52. Bb7? After some precise moves I went astray again. 52. Rb1! Rh2+ 53. Ke1 Ra2 54. Rb6+ Ke5 55. Rxa6=/+ 52... Ra3 53. Rd1 Be6 53... Ke7 54. Re1+ Kd6 55. Bxa6 Rxa5 56. Bb7-/+ 54. Rd6 Ke5 55. Rxa6 Bxc4 56. Ra8 Ra2+ 57. Kg3?! My intuition told me that there might be a mate in the air ... why didn't I listen? 57. Ke1! 57... f4+ 58. Kh3?? 58. Kh4-/+ 58... Be6+? 58... Kf5! 59. Bc8+ Kg5 and mate either on f1 or e6! 59. Kh4 c4 60. Re8 0:08 60... Kd6 0:18 60... c3 61. Bc8 c2 62. Rxe6+ Kd5 63. Re1= 61. Rf8 Rxa5 61... c3 62. Rxf4 Bd5!-+ (62... c2 63. Rf1 Rxa5 is not sure.) 62. Rxf4 c3 63. Be4 Ke5 64. Rf3 Kxe4?? 65. Rxc3 From here on tablebases. Impossible to find the correct moves with less than 10 minutes on the clock. 65... Kf4 66. Rc6? 66. Rf3+!= 66... Bf5? 67. Rc4+? 67. Rc1!= The only one. 67... Be4 68. Rg1! Again the only one. 67... Be4 68. Rc8 Ra3? 68... Ra7 (besides four other moves) and #20 69. Rg8! The only one! 69... Bf5 70. Rg4+ 0:03 - I guess one have to know or find this stale mate motiv to survive. 70... Ke5 0:02 71. Rg3 Ra8 72. Rg5 Ra4+ 73. Kg3 Ra3+ 74. Kf2 Kf4 75. Rg8 Ra2+ 76. Ke1 Ke3 77. Rg3+ Kd4 78. Rg7 1/2-1/2 [Achim Mueller]
