ThreeFoldRepetitionStalemate

class ThreeFoldRepetitionStalemate : EndCondition2D<AbstractChess2D>

Condition for stalemate by three-fold-repetition.

In chess, the threefold repetition rule states that a player may claim a draw if the same position occurs three times.

Two positions are by definition "the same" if the same types of pieces occupy the same squares, the same player has the move, the remaining castling rights are the same and the possibility to capture en passant is the same.

The repeated positions need not occur in succession.
