    When can a perpetual check end a game? Three or thirty-three?

    In my experience perpetual check results in a third repetition more often than not. If I get one I just click "claim draw" with every move and let the system tell me when it's valid, so I don't really know the answer to your question.

    I don't know where you get the number 33 from.
    This is from FAQ and I think is a universal rule of the game
    "No piece capture or pawn movement has occurred for over 50 consecutive moves (100 half moves). Therefore the game has not progressed and a draw may be claimed by either player during their next move."

    I got the number thirty-three from 'being facetious'. Thanks for the reply.
