THE STORY BEGINS

Every piece has a part to play.

The final recorded game of the 1972 match reaches a rook-against-bishop ending with different pawn counts and very different piece activity. Fischer first uses an intermediate bishop check to recover a rook, then invades the second rank and brings his king forward. The recorded score ends with resignation; no unplayed continuation is presented as part of the game.

Take these ideas to your next game

  1. An isolated pawn can still support an active break.
  2. Check intermediate captures before completing a recapture.
  3. An active rook can attack several pawns in succession.
  4. Bring the king into an ending when the concrete threats permit it.

c4 changes the queenside structure while the d5-pawn is under pressure. White answers by capturing on d5 with the knight. The next exchanges lead to a rook on d5, which becomes the target of an intermediate bishop check. The pawn break is part of a concrete sequence rather than proof that the isolated d-pawn is harmless.

Bxh2+ inserts a forcing capture before Rxd5. After the king takes the bishop, Black’s d8-rook captures the rook on d5. Black has not simply given away a bishop: the checking move changes the move order of a liquidation in which both sides must count the pieces and pawns.

Rd2 attacks c2 and makes White’s queenside pawns vulnerable. White captures the a6-pawn with the bishop, while Black takes c2. A later rook exchange leaves a rook against a bishop. Compare activity and accessible targets instead of relying on a simple count of the remaining pawns.

Kf4 brings the king closer to White’s kingside pawns. The king on f4 restricts the white king and supports further play against the kingside. Black’s rook can change ranks while the bishop must watch targets on both wings. The position demonstrates active coordination; the historical result is not a substitute for calculating White’s defensive resources.

Give the king an active role

Fischer brings the king toward the kingside pawns. Compare Capablanca’s king route and identify which enemy checks must be answered before the king can advance.
