Check and Checkmate

When the king is attacked it is 'in check' and must escape at once.

Quick answer

Check means the king is attacked. You must get out of check at once: move the king, block the attack, or capture the attacking piece. Checkmate is a check that can't be escaped in any of those three ways, and it ends the game. You never capture the king; checkmate is the win.

Step by step

When a king is attacked, it is in check. The player in check must get out of check on their very next move.

There are three ways out of check: 1. Move the king to a safe square. 2. Block the attack with another piece. 3. Capture the attacking piece.

Checkmate means the king is in check and there is no way out: it can't move, block or capture. Checkmate ends the game immediately. That's the goal of chess!

Common mistakes

  • Ignoring a check, or making a move that leaves your king in check. Both are illegal.
  • Only looking at king moves when in check. Blocking and capturing the checker are often better.
  • Giving check just because you can. A check that achieves nothing can drive the king to safety.

Tips from the lesson

  • Follow the lines (and knight jumps) that end on the king.
  • Move, block, or capture.
  • Your king guards a7 and b7. Give check along the 8th rank.
  • The king is boxed in by its own pawns.
  • Is the king attacked? If so, can it move, block or capture?

FAQ

Do you have to say 'check'?add

No. It's polite in casual games, but the rules don't require it. Online, the board shows it.

What are the three ways out of check?add

Move the king to a safe square, block the line of attack with a piece, or capture the attacking piece.

What is the difference between check and checkmate?add

In check, at least one of the three escapes works. In checkmate, none does, so the game is over.

Is stalemate the same as checkmate?add

No. Stalemate is when the player to move is not in check but has no legal move: it's a draw.
