The Lucena position
The most important winning technique in rook endgames: building a bridge.
The Lucena position is the fundamental winning setup in rook-and-pawn versus rook endgames. If you can reach this position, you win. If you know how to defend against it (the Philidor position), you draw.
The position arises when the attacking side has a pawn on the seventh rank, the attacking king is beside the pawn on the far side, and the attacking rook has cut off the defending king.
The winning technique is called 'building a bridge.' The attacking rook cuts off the enemy king, the attacking king steps out from behind the pawn, and then the rook swings to a rank in front to shield the king from perpetual checks. It takes practice but follows a fixed recipe.
Examples
Step 1 - rook cuts off the enemy king on the fifth rank
White plays Rc5, cutting the Black king off on the e-file. Now the White king will emerge from behind the pawn. This is the beginning of 'building a bridge' - restricting the defending king is the priority before the king steps out.
Step 2 - king steps out from behind the pawn
White plays Ka7, stepping the king out from behind the pawn now that the rook covers checks along the c-file. Black's rook can only check from the side; each check, the White rook will step to block it (Rc4, Rc3, Rc2 - the 'bridge'). The pawn will promote.
