The Lucena Position

How to Play This Endgame

The Lucena position occurs when the stronger side has a pawn on the 7th rank with the king in front of it. The winning technique is called 'building a bridge' — the rook goes to the 4th rank, the king emerges, and the rook blocks checks by interposing on the 5th rank. This is arguably the single most important endgame technique to memorize. Named after a 15th-century manuscript, though the exact attribution is debated.
