Endgame theme
Lucena position
The classic rook-endgame win: your king steps out, your rook builds a bridge, and the pawn promotes.
The idea in one minute

Study advice
Learn the pattern slowly once. Then recognize the setup in your games — don’t memorize move numbers without the picture.
Who it suits
Players comfortable with basic rook activity who want reliable conversions.
