What is perpetual check in chess?

Perpetual check occurs when one side can give repeated checks that the opposing king cannot escape without returning to the same position. Under standard rules, repeating the position three times can result in a draw if claimed correctly.

How do I spot a draw by repetition?

Track the king’s squares and the checking piece’s placement after every forcing sequence. If the same position can recur three times with the same side to move and identical legal rights, a draw by repetition may be available.

How does queen endgame technique use perpetual check?

A queen can often check from a distance while avoiding exchanges and maintaining control of escape squares. Keep the checking queen safe, prevent the enemy king from approaching, and calculate whether the checks can continue indefinitely.

What should I calculate first in a chess endgame?

Andrew Tang (Black) Puzzle: Perpetual Check — Draw

Perpetual check is a defensive resource in the chess endgame when one side cannot force progress but can keep checking the exposed king. By using repeated checks from safe squares, the attacker prevents the opponent from consolidating material or activating the king. This pattern often turns a difficult position into a draw by repetition. The key is not simply giving checks, but choosing checks that preserve escape routes and maintain control of the checking distance.
