THE STORY BEGINS

Every piece has a part to play.

White collects queenside pawns, while Anand activates his bishops against the white queen and back rank. A short tactical sequence changes the material balance and leads to a rook-and-minor-piece ending. Study the bishop moves together: their strength comes from connected threats, rather than the value of a single diagonal.

Bb7 activates the bishop opposite White’s king. Its long diagonal combines with Black’s other bishop and the queen on d5. White’s bishop returns to c5 in the recorded line, after which Black’s second bishop gains a tempo against the queen.

22 … Bh4

Bh4 attacks the queen while keeping both bishops active. White moves the queen to e2 and Black brings a rook to c8. This is a coordination move: the bishop’s tempo gives the rook time to join. Check White’s forcing alternatives before assuming the two bishops alone decide the position.

Bxc2 starts a sequence involving both sides’ rooks. White takes a rook on b8 with the bishop, and Black’s bishop takes the rook on d1. White recaptures that bishop and Black’s remaining rook captures on b8. Count the complete sequence before assessing the rook-and-minor-piece ending.

Rxb2 wins a pawn with an active rook. White’s knight has moved to a5, and the white king still needs protection from the rook and bishop. Black’s rook can switch to c2 later, keeping targets on the second rank. Compare activity as well as the immediate material gain.
