After two rounds, Kasparov and Kramnik led with 2 points, followed by Adams and Svidler 11/2; Onischuk, van Wely and Leko 1; Polgar, Lautier, Piket and Shirov 1/2; Shaked 0.
Adams's first-round win against the Ukrainian grandmaster Alex Onischuk was a typical display of controlled aggression with the white pieces. His 9.dxc4! (instead of the more obvious recapture with the knight) was part of a plan of white-square domination which eventually left Black with a miserable bishop against a rampaging knight. White's energetic advances of his a- and h-pawns were all part of this strategy, and his development of the rook to a3 was simply the quickest way to bring it into the attack.
Black's 26...d5 was intended to free his game, but instead resulted in its immediate collapse thanks to a series of tactics based mainly on knight forks. At the end, Black was a pawn behind and about to lose another one.
White: Adams - Black: Onischuk
