About these games

After 3...e6 4.O-O Nge7, Black keeps the option of meeting Bxc6 with ...Nxc6 and so avoids doubled pawns, and the knight on e7 leaves the f-pawn and the d-pawn free to advance. White chooses between 5.c3, preparing d4 behind a solid pawn chain, and 5.Re1, which opens the centre quickly. Black's usual reply is ...a6 to question the bishop, followed by ...d5 or queenside expansion.

Grischuk–Kasparov went 5.c3 a6 6.Ba4 b5 7.Bc2, and Black gained space with ...Bb7, ...d5 and 9...d4, answering 9.e5 by fixing a pawn on d4. White set up with f4, but 17.Rf3 moved the score from −0.48 to −2.58. After 17...Bxe4 18.dxe4 d3, the knight went 19...Nc2 and 20...Ne1 and won the exchange on f3. The queens came off with 24.axb5. White's knight and f- and h-pawns kept the position close to level, at −0.25 after 44...Ra6. Then 45.Nd4 took it to −2.71, the doubled rooks won the knight with 50...Raxb3, and Black won.

Carlsen–Gelfand took the other route: 5.Re1 a6 6.Bf1 d5 7.exd5 Nxd5 8.d4 opened the centre with no fixed pawn chain. White formed a queenside majority with c4 and b4, and after 35.Qxe5 had connected passed b- and c-pawns. Here the game turned: 39...Ra1 moved the score from +0.91 to +3.05. The pawns then advanced, 44...Qxf1+ went to +5.35 and 46.b7 to +7.09, and White won.
