Ladder mate
A ladder mate is a checkmate on the edge of the board in which two rooks, or a rook and a queen, take turns giving check on neighboring lines until the king runs out of room.
Also called: rolling rooks mate
Two long-range pieces are all that this technique needs. One rook cuts off a rank or file, and the second rook gives check on the next line along. The king must step toward the edge, and the first rook jumps ahead to the line beyond, so the pieces climb the board like rungs on a ladder.
The method is a staple of endings where one side has two heavy pieces against a lone king, and it also finishes middlegame attacks when the defender's pieces are far from their king. It needs no help from the attacker's own king: each rook stands on a line the enemy king cannot cross, so the two work at a distance instead of protecting each other.
To defend, avoid letting both rooks reach adjacent lines with your king on the edge, and bring a piece close enough to interpose or attack one of the rooks. Trading a rook, or giving your king a route toward the center, also ends the pattern.
Keep an eye on the distance between the enemy king and your rooks. If the king walks up to the rook that is about to move, that rook can be captured; shift it to the far end of its line first, then continue the climb.
