Shakhriyar Mamedyarov leads the Dortmund tournament with 3/4 after his draw with Vladamir Kramnik was not matched by Ruslan Ponomariov who went down to a loss against Le Quang Liem. Arkadij Naiditsch drew against Peter Leko. All of the games were interesting but perhaps not particularly thrilling.

Almost certainly Ponomariov didn't think carefully enough when he played 18...h5? although I'm not 100% certain it should be the losing move, it was certainly the one that got him into trouble after Le played the very clever 19...Nxg6.

Le Quang Liem

Position after 18...h5?

The game continued:

19. Nxg6! Nxg6 20. Bd6!! Qe8

Forced as 20... Qxd6 21. Bxf7+ Kxf7 22. Rxd6 Bxe4 23. Re1 is unplayable.

21. Qxe8+ Rxe8 22. Bxb7 Rad8 23. Bb4

23. g3

23... Nf4?!

23...a5 24. Ba3 Rxd1+ 25. Rxd1 Bxc3 looks a much better idea.

24. Kf1 Rxd1+ 25. Rxd1 Nd3 26. Bd5 Rc8 27. Rb1 Nxb4?! 28. Rxb4 Bxc3 29. Ra4 Rc5 30. Rxc4 Rxc4 31. Bxc4

Le Quang Liem

Position after 31.Bxc4

and Ponomariov never looked close to saving this ending in spite of the bishops of opposite colours. Here he should probably play 31...Kg7, his 31...h4? in this position is probably the final mistake as it allowed Le to set up a winning position with two connected past pawns.

31.... h4? 32. f4 Kg7 33. e5 f6 34. exf6+ Kxf6 35. g3 Kf5 36. Bd3+ Ke6 37. Kg2 hxg3 38. hxg3 Kd5 39. Kf3 Kd4 40. Ba6 Kc5 41. g4 b5 42. g5 Kb6 43. Bc8 Kc7 44. Bf5 a5 45. Bd3 b4 46. Bc2 Kd6 47. Kg4 Bd2 48. f5 Ke5 49. f6 Be3 50. Kh5 Bc5 51. Kh6 Ke6 52. g6 Kd5 1-0

Shakhriyar Mamedyarov took the lead alone almost by default. Today he drew against Kramnik with white. Photo © Georgios Souleidis : http://www.sparkassen-chess-meeting.de/2010/fotos.html

Shakhriyar Mamedyarov against Vladimir Kramnik was not a game without interest. In a Queen's Gambit with 5.Bf4 Kramnik had an isolated pawn but never seemed in any real trouble. Here the pieces and pawns came off.

Arkadij Naiditsch against Peter Leko had its moments of interest before they drew. Photo © Georgios Souleidis : http://www.sparkassen-chess-meeting.de/2010/fotos.html

Arkadij Naiditsch got something of an advantage against Peter Leko on the white side of a Ruy Lopez. In this position white has more than enough threats to recover his pawn.
