Fivefold repetition

Fivefold repetition is the rule that a game is drawn automatically, with no claim needed, once the same position has appeared at least five times.

Where threefold repetition has to be claimed, fivefold repetition is a safety net that works on its own. If the same position has appeared five times, the game is drawn immediately, whether or not either player notices or wants it. The arbiter does not need to be asked and neither player can decline. The occurrences do not have to be consecutive, and they do not need to arise from the same sequence of moves. The same strict definition of position applies as for the threefold claim: identical placement, identical side to move and identical possible moves. In real games it is rare for fivefold repetition to matter, because a player who wants the draw will claim at three, and a player who does not want it will vary the moves. It becomes relevant when both players keep shuffling in a clearly drawn position and neither bothers to claim, and in computer chess, where engines may repeat without any human claiming. For your own play the lesson is practical: if you are repeating, decide deliberately whether you want the draw. The arbiter and the rules will otherwise decide for you.

Compare it with Seventy-five-move rule. The seventy-five-move rule ends the game in a draw automatically when each player has made at least seventy-five moves without a pawn move or a capture, unless the last move was checkmate.

Knowing "Fivefold repetition" is the easy part; what to practice next depends on your rating, and the improvement plans by rating band list the habits worth building at each level.
