Perpetual check: a practical example
Repeated checks may produce the same position three times, allowing a repetition claim when the conditions are satisfied. The phrase is a practical description, not a separate automatic draw rule in the FIDE Laws.
How to use the idea in your games
Verify that the checks really can continue. One quiet king move, interposition, or exchange may end the sequence, and repeated checks do not necessarily repeat the same position.
A useful study question
Can you explain perpetual check in your own words, identify it in a position, and describe when the idea does not apply? Test the explanation on a legal board before relying on it.
