Achim Mueller (1927) - Holger Lehmann (2188) [A57]

Muensterland Open 2009


1. d4 Nf6 2. c4 c5 3. d5 b5 4. Qc2 b4 I didn't knew this move. From a general understanding this can't be that good because White already owns the center. But I probably misplayed it later. 5. b3 5 5... d6 6. Bb2 10 6... Nbd7?! Critizised by Holger later. 7. Nf3 7. e4 g6 8. f4 Bg7 9. Nf3 7... g6 8. g3 Bg7 9. Nbd2 a5 10. a4 1:38 10... Bb7 1:40 11. Bg2 e5 12. e4 10 12... Qe7 13. Nf1 Kd8 14. Bc1 h6 15. Ne3 Kc7 16. Bd2 Nh7 17. O-O-O Ndf6 18. h4 Bc8 19. Bh3 Bxh3 20. Rxh3 1:04 20... Qd7 1:16 21. Rhh1 10 21... Raf8 22. Nh2 Ng8 23. Rdf1? 23. f4 exf4 24. gxf4 Re8 25. Rde1 Ngf6 26. Nd1+/= 23... Ne7 24. Kb1? 24. f4 24... f5 25. f3 f4 26. gxf4 exf4 27. Ng2 g5 28. hxg5 hxg5 29. Ng4 Nf6 30. Nxf6 0:33 30... Bxf6 0:49 31. Bc1? Again (probably) the wrong plan. The bishop belongs to the c1-h6 diagonal and one knight to d3. xf4 31... Ng6 32. Ne1 Rh3 33. Rxh3 33. Qd1 Rfh8 34. Nd3 Bd4 33... Qxh3 34. Rg1 Qh6 35. Bb2? The decisive error 35... Bxb2 36. Qxb2 Ne5 37. Qg2 g4 38. fxg4 f3 39. Qf2 Qf4 40. g5 0:01 40... Qxe4+-+ 0:12 41. Nc2 35 41... Ng4 42. Qh4 f2 43. Rf1 Rf3 44. Kb2 Rc3 45. Rxf2 Nxf2 46. Qxf2 Rf3 47. Qe1 Qe5+ 48. Ka2 Qxe1 49. Nxe1 Rf2+ 0-1 [Achim Mueller]

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. a4!? a6 8. Na3 Be6 9. Bc4 Rc8 10. O-O 1:58 10... Nd4 1:52 11. Bd5 I had prepared a little bit against 7.a4 but this move was new to me. 11... Qb6 20 12. Qd3 Be7 10 13. Nc4 Qc5 14. Ne3 Rc7?! Perhaps the wrong plan. I wanted to play b5 later without the annoying Bb7 14... Nxd5 15. Nexd5 (15. exd5 Bd7 16. Ne4 Qc7 17. c3 Nb3 18. Rb1 f5-/+) 15... f5 16. Be3 fxe4 17. Qxe4 Ne2+ 15. Kh1 O-O 16. f4 exf4 10 17.
