The struggle in the open section of the Olympiad became tenser – all six matches in the leading group ended in +1 victories. The leaders, Ukraine, defeated Azerbaijan and maintained first place. Vassily Ivanchuk lost to Shakhriyar Mamedyarov in an instructive Benoni.
15. a5N 15. Nb5 Nxb5 16. Bxb5 Rd8 17. a5 a6!? was Kramnik-Topalov, Dortmund 2001. 15... Bb7 16. Nb5 Nf6?! Better seems 16... Nxb5 17. Bxb5 Red8 (17... a6!?) like in Kramnik-Topalov, as with the queen on e7 Black can answer 18. Nc4 with 18... Ne5. 17. Nxc7 Qxc7 18. Bb5 Reb8 Now Black is too late for 18... Red8 19. Nc4 Nd7 20. Bf4 Ne5 because with the queen on c7 this allows White to create a protected passed pawn. 19. Nc4 bxa5 20. Bf4! Bf8
21. e5! As so often in the Benoni, the central pawn break gives White a clear advantage. See the game viewer for the rest of the game.Ponomariov and Radjabov drew in a Dragon where White went for the move 9.g4 that was popular in the early eighties. That made 1.5 points for Azerbaijan, but Ivanchuk's team mates Pavel Eljanov and Zakhar Efimenko avenged him by beating Rauf Mamedov and Eltaj Safarli.One point behind the leader are Russia 1 and France. The Russians won their match against the defending champions – Armenia. Peter Svidler had played quite a few draws so far, but yesterday he decided the match in his beloved Grünfeld.
26. Bd6? White had to play 26. Bb6 Bf8 27. d6 26... Ne3! Suddenly White's position was beyond repair.
Kramnik and Aronian drew a quiet game
A position from the Dragadorf main line in which White's Kb1 and Nc1 was a new plan. 19... d5?! Not possible here. 20. exd5 Bxd5 Taking with the knight eventually drops the h-pawn. 21. Re2! Re8 22. Nd3 e4 23. Rde1 Bxb3?! 24. cxb3 Rxd3 25. Nxe4
At first sight you wouldn't say so, but Black is completely lost here. 25... Qd8 26. Qc1+ Kb8 27. Qf4+ Ka8 28. Qxf6 Rd1+ 29. Rxd1 Qxd1+ 30. Ka2 Qxe2 31. Qc6+ 1-0
Jobava vs Vachier-Lagrave
18. Nf4! exf4? After 18... O-O 19. Ne2 Qb2 20. Rb1 Qa2 there's no way to catch the queen, it seems. 19. Bd4 Qb4 20. Ra4! and White won after 63 moves.In the 10th round Ukraine plays against France. Other important matches are China-Russia 1, USA-Israel, Spain-Georgia, Serbia-Poland and Czech Republic-Armenia.The Russian women team won their 9th match in a row. With just two rounds to go they are four points ahead of the rest of the field, and nobody seems to doubt their overall victory. In the 9th round they were a bit lucky as with a score of 1.5-1.5 against Serbia, Nadezhda Kosintseva had a bad position. However, after five hours of play she not only managed to survive, but even won the game.
33. Qe3? 33. Qd4 Qxd4 34. Rxd4 Bxe1 35. exf6 +- 33... Bxd5 34. Rxd5 Bxe1 35. Qxe1 a3
36. Qc3? Oops. 36... a2+? Double oops. 36... Qg1+ 37. Ka2 axb2 is curtains. 37. Ka1 Qg1+ 38. Kxa2 Ra6+ 39. Ra5 Rxa5+ 40. Qxa5 Qxg4 41. Nd6 and in this ending at some point White blundered a number of pawns.The main medal contenders also won their matches: Georgia defeated Russia 2 with a minimal margin, and China won 3-1 against Hungary. Ukraine crushed Croatia 3.5-0.5. Russia has 18/9 and five teams have 14 points: China, Ukraine, Georgia, India, and Bulgaria.
