King and Rook vs. King

Key Ideas

• The rook alone confines the enemy king by cutting off an entire rank or file — the king can never cross that line.
• Advance your own king toward the enemy king while the rook holds the line, shrinking the box one step at a time.
• Once the kings stand in opposition (facing each other, one square between them), the rook delivers mate along the edge the enemy king has been pressed against.
• If checking too early would let the enemy king escape back toward the center, simply wait with a rook move along the cutting-off line instead — there's no rush.

How It Works

This is the second "basic checkmate" every player is expected to know cold, and it's in some ways more mechanical than the queen version: the rook cuts the board in half along a full rank or file, and the enemy king can never cross that line no matter what it does.

The attacking king then simply walks up, step by step, shrinking the enemy king's remaining space until the two kings face each other in opposition. At that point, the rook delivers checkmate along the edge of the board the enemy king has been driven to.

The technique requires patience: pushing the rook's checking line forward too soon, before the kings are properly in opposition, often just lets the enemy king slip back toward the center and undoes the progress made so far.
