Bxf6 gxf6 {A typical pawn structure arose. Both black flanks have been weakened. However, the four black pawns in the center look like a strong shield in front of their king. Still, they are not ideal and have a soft spot: the e6 one. If White manages to destroy that pawn or force it to move, all the light squares in the center will fall into the first player's hands.} 12. Kb1 Qb6 13. f5 O-O-O {The king is not perfectly safe here either, but Black can at least connect his rooks.} 14.

The knight is transfered to the f4 square.} Bc8 {In the confession box Carlsen said that he had done everything wrong so far, but as long as his bishop pair is on the board, he can hope for the best. This is what his coach Simen Agdestein taught him once.} 16. Nf4 Ne5 17. Be2 {Now Nf3-d4 is a deadly positional threat. Carlsen needs to hurry with the counterplay.} d5 ({Better seemed} 17... Nc4 18.

The black kingside pawns are now practically dead, but the bishops gain more scope. These sudden changes in the strategic/dynamic balances is one of the world champion's main weapons.} ({The players probably didn't know about this earlier game:} 18... Nxf3 19. Bxf3 e5 20.
