Puzzle 1 of 5

Checkmate in one move.

Your move

💡 Need a hint?

One rook already blocks the row next to the king. Bring the other rook to the edge row to give check.

What you learn here

Two rooks (or a rook and a queen) can checkmate by taking turns: one guards the row in front of the king, the other checks on the edge row. A single rook can also mate with the help of its king.

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