THE STORY BEGINS

Every piece has a part to play.

A central pawn advance and a queen-trade combination lead to an unusual ending in this Candidates game. Aronian creates a c-pawn close to promotion, but Kramnik’s king controls its promotion square. The later king-and-bishop play shows why the promotion square, the king’s path and the distant pawns must be considered together.

  1. Central pawn play can change a bishop’s diagonal.
  2. Check an intermediate attack before recapturing a queen.
  3. A passer on the seventh rank still needs support.
  4. Compare promotion control with the kings’ routes.

f4 challenges White’s bishop and changes the centre. White uses the rook actively on c5, while Black’s queen steps to d6 before taking on e3. The central tension is tactical: moving a pawn near the king can open useful lines for either side. Compare White’s checking bishop ideas with Black’s capture.

Bxe5 changes the exchanges in the centre. White recaptures with the knight, and Black’s rook takes on c5. A knight check on g6 then starts another forcing sequence. Keep track of which rook and bishop remain before judging the material balance after the queen exchange.

Be4 creates an intermediate attack on White’s queen. White takes Black’s queen on d6 with the rook, but Black’s bishop then captures the queen on c2. The sequence trades queens through two different captures. Identify that intermediate move before assuming Black must immediately answer the pawn capture on c5.

Bg8 removes the bishop from the white king’s approach. Black’s king on d7 controls c8, so White cannot keep a new queen there without further support. The bishop retreats while the king stays near the pawn. In the recorded line White promotes with check and Black captures the queen with the king.
