THE STORY BEGINS

Every piece has a part to play.

In game eight of the 2004 championship match, White’s passed a-pawn races toward promotion while Black attacks the king. Leko’s bishops, rook, queen and knight take turns creating threats. Study the rook offer together with the next checking moves, then ask why an advanced passed pawn does not settle the result by itself.

23 … Re2

The move 23...Re2 attacks the queen. The recorded Qxe2 is met by Bxe2. This does not mean White has no legal queen retreat. The offer must be tested against alternatives, the king’s safety and the passed a-pawn. In the recorded line, Black gives up the rook and takes White’s queen, then keeps making threats instead of pausing to count the material.

24 . Qxe2
24 … Bxe2

25 … Qd3

The game continues 25...Qd3, placing the queen near White’s king while the a-pawn keeps advancing. Do not assume a material imbalance decides this position. White has a rook, minor pieces and a passed pawn; Black has a queen and active minor pieces. The pieces around the king affect the escape squares. Compare the saved alternatives to the queen move and calculate the reply to the king’s route through f2. The recorded win comes from the concrete continuation, not from calling every queen move decisive.

26 . Kf2
26 … Bxf3

27 … Ne4+

Leko continues 27...Ne4+, bringing the knight into the attack with check. After the king moves, the recorded knight capture on c3 is followed by a pawn recapture and a queen check on c3. The sequence changes which squares are occupied and clears the queen’s route toward a1. Calculate the intervening replies rather than treating the knight’s first check as the whole combination.

The final recorded move is 32...g4, attacking the f3-knight. White resigns. The a7-pawn cannot be evaluated in isolation: moving it to a8 clears the a-file, allowing the queen on a1 to capture the promoted piece. Meanwhile g4 creates a fresh threat to a defender near the white king. No checkmate is recorded in the PGN; use the saved variations to compare White’s remaining choices.

Result: 0-1. The recorded score ends here; it does not imply checkmate.

This does not mean White has no legal queen retreat. The offer must be tested against alternatives, the king’s safety and the passed a-pawn. In the recorded line, Black gives up the rook and takes White’s queen, then keeps making threats instead of pausing to count the material.

A CONNECTED IDEA

A passed pawn still needs support

Kramnik’s a-pawn reaches a7 in game eight but its promotion square remains controlled. Compare the b6 advance in game fourteen: identify what the pawn restricts and which pieces can support its progress.
