'''Stalemate''' occurs if the [[Side to move|side to move]] is not [[Check|in check]] but has no [[Legal Move|legal moves]]. Stalemate results in a draw instead of losing the game if in check, and it is likely to occur in late [[Endgame|endings]] only, where it is a regular resource that can enable the player with the inferior position to draw the game, i.e. in [[KPK]] or [https://en.wikipedia.org/wiki/Queen_versus_pawn_endgame KQKP] with [https://en.wikipedia.org/wiki/Queen_versus_pawn_endgame#Rook_pawn rook pawn] or [https://en.wikipedia.org/wiki/Queen_versus_pawn_endgame#Bishop_pawn bishop pawn] on the seventh rank <ref>[http://www.talkchess.com/forum/viewtopic.php?t=66640 Marcel Duchamp endgame "splits" engines / hash phenomenon] by [[Kenneth Wingate W. Regan|Kenneth Regan]], [[CCC]], February 19, 2018 » [[Chess Problems, Compositions and Studies]], [[Arts#:Category:Marcel Duchamp|Marcel Duchamp]], [[Transposition Table]]</ref>.
In others contexts, the word ''stalemate'' is also used for a [https://en.wikipedia.org/wiki/Metaphor metaphor] when a conflict resolution seems difficult or impossible, i.e. a [https://en.wikipedia.org/wiki/No-win_situation lose-lose situation].
