THE STORY BEGINS

Every piece has a part to play.

Kramnik’s active pieces and queenside gains do not make this 2013 Candidates game a simple conversion. Carlsen challenges the centre, invades with a rook and later offers a queen exchange. The drawn ending illustrates how a rook and bishop can maintain counterplay against a side with useful pawns and active squares.

e5 challenges White’s centre before the rooks become fully active. White develops a rook to d1 and Black uses the b-file. The pawn break gives Black practical central play while White’s pieces are still developing. Compare it with the other saved candidates; it is a supported defensive choice rather than the only possible move.

Rxb2 takes the pawn and activates the rook on the second rank. White captures the c4-pawn, after which the rook returns to b7. Keep that retreat in the calculation: an invading rook can become a target if its escape is overlooked. The remaining queenside exchanges lead to a new material balance rather than ending the struggle.

Qc4 offers a supported queen exchange. White first advances the a-pawn, then exchanges queens after Black’s f-pawn move. Black’s bishop recaptures on c4 and the rook later takes e2. Follow the whole transition: the active rook supplies counterplay after the queens leave.

Bc6 prepares an active bishop route toward f3. The bishop reaches f3 in the recorded continuation while the rook keeps access to the second rank. White’s rook and queenside pawn remain dangerous, so Black must keep making concrete threats. The score ends in a draw after further rook checks rather than an attempted passive blockade.

A CONNECTED IDEA

Keep a repeatable defensive resource

Carlsen’s rook keeps access to the second rank while the bishop stays active. Compare the repeatable checks in Kosteniuk–Hou and identify the resource that stops a passive defence becoming necessary.
