The Lucena position is the key winning setup in rook and pawn against rook: the pawn stands on the seventh rank, its king sits on the promotion square, the enemy king is cut off, and building a bridge with the rook wins. Picture the attacker's pawn on d7 with its own king on d8. The pawn cannot advance while the king blocks it, and as soon as the king steps off, the defending rook starts checking from a distance. The defending king is shut out by the attacker's rook along a file, so those checks are the defender's only resource. The cure is to prepare a shelter in advance. First, bring the rook to the fourth rank, staying on the file that cuts the enemy king off. Second, step the king off the [promotion](https://georgelichess.com/glossary/promotion.md) [square](https://georgelichess.com/glossary/square.md) on the side away from the enemy rook and walk it down the board while the checks come. Third, when the king reaches the fifth rank, answer the next check by putting the rook between the two, and the pawn promotes. The rook on the fourth rank is the bridge that gives the method its name. Order matters. Leaving with the king before the rook is on the fourth rank leaves it nowhere to hide. The method also needs a pawn on the b- to g-file; with a [rook pawn](https://georgelichess.com/glossary/rook-pawn.md) the king has too little room and other methods are required. For the defender, the lesson is to avoid the setup altogether: keep the king near the pawn's path so it cannot be cut off, and aim for the Philidor defense while the pawn is still further back. Also called: building a bridge. ## Example position White to move. The pawn is on the seventh with the king on d8, the rook on f1 cuts Black's king off, and Black's rook on the c-file stops the king leaving that way. White builds the bridge: 1.Rf4 Rc1 2.Ke7 Re1+ 3.Kd6 Rd1+ 4.Ke6 Re1+ 5.Kd5 Rd1+ 6.Rd4, and the checks are over. Position (FEN): `3K4/3P2k1/8/8/8/8/2r5/5R2 w - - 0 1` Also worth reading is [Cutting off the king](https://georgelichess.com/glossary/cutting-off-the-king.md). Cutting off the king means placing a rook on a file or rank so that the enemy king cannot cross it, which keeps the king away from the pawns and often makes a rook ending easy to win. It sits close to [Frontal checks](https://georgelichess.com/glossary/frontal-checks.md). Frontal checks are rook checks given from in front of the enemy king, facing the direction in which it is moving, as opposed to checks given from behind. A neighboring idea is [Rook and pawn versus rook](https://georgelichess.com/glossary/rook-and-pawn-versus-rook.md). Rook and pawn versus rook is the ending where one side has a rook and a single pawn against a lone rook, a common practical ending whose result usually turns on where the defending king stands.
