Round 6 of the FIDE Grand Prix in London saw a fight of continents between Hikaru Nakamura and Wang Hao.
Surprisingly, Hikaru chose a quiet line with double fianchetto 2.g3 and 4.b3. Wang Hao had a pretty safe position and waited the time control to see a big blunder (45.Nxa4??) from the American player.
Alexander Grischuk and Peter Leko, both pursuing the Grand Prix leader Boris Gelfand and playing white pieces, tried to reduce the gap. Alexander avoided the main weapon of Michael Adams, the Marshall gambit in Ruy Lopez, and went for 6.d3. White quickly opened the centre forcing black to give away a pawn. In compensation, Adams held a pair of bishops. It was enough to secure the draw in the endgame.
The longest game of the day saw Veselin Topalov facing Leinier Dominguez. In response to Cuban’s Chebanenko Slav defence, Veselin decided to take space immediately with 7.Ne5 and 8.f4. Topalov gradually increased the advantage, sacrificing a piece to beautifully win in the endgame.
Back to business with the only leader of the tournament, Boris Gelfand (3,5/5), played against Vasily Ivanchuk. The Israeli player went for an aggressive line against the Queen’s Indian, sacrificing a pawn very early in the game. Both players admitted later that it was a complicated game and finally the draw was agreed before the time trouble, on move 25.
Rustam Kasimdzhanov played Shakhriyar Mamedyarov in one of the most fashionable lines of the Meran Slav defence. The position became very sharp when Mamedyarov decided to develop his initiative on the King’s side, pushing his “f” and “h” pawns. The 38th move was a terrible blunder from the Uzbek player and “Shak” jumped on the opportunity to score a full point.
Peter Leko and Anish Giri explored a topical line of the Sicilian Najdorf. Peter quickly gave a pawn away in order to seize the initiative and two bishops. Anish launched the counter attack on the “a” file and managed to equalize. Both players decided to quickly repeat the moves and agree a draw.
