By 1800, a claim under the rule could be made only in certain specified types of endgame, which varied from one set of rules to another. The move-count started when the request to implement the rule was made (instead of going back to the last capture or pawn move) and a capture or a pawn move did not reset the count. The rules used at the 1883 London tournament reset the count if there was a capture or pawn move, but still started the count when the claim to apply the rule was made instead of going back to the last capture or pawn move .
