The story behind the game
Both sides build threats in this King’s Indian encounter from the 1959 Candidates tournament. Tal’s pawn reaches c6 while Fischer’s queen and rooks work toward the white king. White later offers a rook to make a knight fork possible. The lesson is to compare concrete threats instead of assuming one attack is faster.
Take these ideas to your next game
- A pawn wedge can restrict the defender’s coordination.
- A rook lift may support defence as well as attack.
- Look for a knight fork after an exchange offer.
- Recalculate checks when a central pawn moves.

c6 gains space and challenges Black’s coordination. Black first activates the queen with Qg5. After the b-pawn takes on c6, White’s d-pawn can recapture there, preserving the advanced wedge. Keep the identity and route of that pawn clear while comparing Black’s kingside threats.
Rf3 brings the rook into the contest around the kings. White can double rooks on the f-file while Black does the same. The rook lift does not settle which attack is stronger. Compare checks, captures and the knight’s central jumping squares before choosing a pawn move around the white king.
Ne6+ is the strongest saved candidate and forks the king and bishop. Tal first played Rxf4 in the recorded game, replacing the bishop on f4 with a black rook after the recapture. The saved analysis prefers giving the knight check immediately, attacking the bishop instead. Compare the move orders before offering a rook: the same knight square can attack different pieces in the two lines.
e5 attacks the rook and changes the queen’s routes. Black captures the pawn with the d-pawn in the recorded line. White then checks from d7. Compare the rook’s defence, the knight on f4 and the queen’s checking squares together: the pawn advance works through their coordination.
Result: 1-0. The recorded score ends here; it does not imply checkmate.
