Your move

💡 Need a hint?

Put a rook or queen on the black king’s back row, where its own pawns stop it from escaping.

What you learn here

Checkmate: the king is in check and cannot escape — no move, no block, no capture. A king behind three unmoved pawns is often mated on its back row, so give your own king an escape square.

Chapter 4 — Checkmate in one: Find the one move that leaves the king in check with no escape. Watch out for stalemate!
