As noted above, one of the players must claim a draw by threefold repetition for the rule to be applied, otherwise the game continues.  In the fifth game<ref>{{cite web|url=http://www.chessgames.com/perl/chessgame?gid=1241495 |title=Capablanca vs. Lasker, 1921 |publisher=Chessgames.com |access-date=2020-07-03}}</ref> of the [[World Chess Championship 1921|1921]] [[World Chess Championship]] match in Havana between [[José Raúl Capablanca]] and [[Emanuel Lasker]], the same position occurred three times, but no draw was claimed. After 34...h5 ({{em|see diagram}}), the moves were:

:'''35. Qd8+ Kg7'''
:'''36. Qg5+ Kf8''' (second time)
:'''37. Qd8+ Kg7'''
:'''38. Qg5+ Kf8''' (third time)

Capablanca had repeated the moves to gain time on the clock (i.e. get in some quick moves before [[time control]]). The game continued without a draw being claimed; Lasker [[blunder (chess)|blundered]] and [[resign (chess)|resigned]] on move 46.<ref>{{Harvcol|Kasparov|2003|pp=266–67}}</ref>  (Capablanca went on to win the match and become world champion.)
