Back-rank mate: trapped behind its own pawns

What it looks like

After castling, the king stands behind three pawns. That is good shelter against most things, but not against a rook or a queen that gets onto the first or eighth rank. Then the pawns are in their own king's way, and the check along the rank is mate.

Air: the simple defense

The defense is a single pawn move, made in time: push the h-pawn or the g-pawn one square, and the king has a square to go to. That is called giving the king air, or making luft. See the difference:

The move costs a tempo, and that is why it gets forgotten. But anyone who has lost a game on the back rank rarely forgets it again.

Bernstein–Capablanca, Moscow 1914

José Raúl Capablanca of Cuba, later world champion, called this game his most finished and artistic. It ends with a single queen move. Black's queen goes to b2 and attacks both White's queen and the rook on c3, and White's king has no air. White resigned.

Here is what would have happened if White had taken the queen:

The most famous back-rank threat of all is otherwise Adams–Torre, New Orleans 1920, where White offers the queen again and again and Black can't take it, because Black's queen and rook have to guard the back rank. But the game was first printed five years later, and the chess historian Edward Winter has collected what speaks against it: two of Torre's friends told his biographer that the game was never played. It is beautiful anyway, as a puzzle.

See it coming, and defend

• A king behind three pawns, with no air. Check whether your opponent has a rook or a queen that can reach your back rank.
• The last defender. Often a single piece guards the back rank. If your opponent can take it, lure it away or give it two jobs, it is time to give the king air. Read about overloading and deflection.
• Open files. A rook on an open file can reach the back rank in a single move.
• Air in time. h3 or h6 when things are quiet, not when the mate is already threatened.
