reversed Dragon, though there are no games in the database with this exact
position!} Qd7 13. Nce4 Bh3 {Trading off the dragon bishop is very normal.
Black wastes some time on this operation, but it is more than acceptable.} 14.

the ability to pressure a3 (after a4 from Black) and e2, which should give him
enough counterplay.}) 18... exd4 19. a4 Qd5 {Carlsen mentioned he didn't know
what else to do, this leads to a draw after many trades.} 20. Qxd5 Nxd5 21.

the active rook.} 24. Rfe1 {no Rae8 because a5 is hanging} Rxe1+ 25. Rxe1 Bb4 {
more trades} 26. Rc1 {forced} (26. Bxb4 axb4 {gives Black an obvious edge in

7. c5 Ne4 8. a3 {Grischuk played this move very quickly, but it is not the
most logical move. The move itself doesn't threaten b4 yet, but it does cover
against b6 since b4 is not available for the bishop on e7.} (8. Qc2 {and}) (8.

sacrifice nets him two pawns and a strong initiative, using his pawns as spear
points. Grischuk was playing quickly up to this point, but went into a long
thin after accepting the knight.} 16. dxc5 Bxc5 17. O-O $5 (17. exf4 gxf4 18.

is too lenient on Black's position. Asked after the game what they thought of
Wesley's play, most of the players agreed that it looked completely wrong and
anti-positional. "If it was White to move, I would consider playing Rc6 here"
- Anish Giri.} (23. Nb4 $1 Bxc6 (23... Bh6)) 23... Bh6 24. Be1 {removing the
bishop from potential g3 moves with tempo.} h4 {here the pawn on g4 is clearly
