A transposition in chess is a sequence of moves that results in a position which may also be reached by another, more common sequence of moves. A transposition of moves usually refers to an opening, in which a given position is arrived at by a different sequence of moves. Players sometimes use transpositions deliberately in order to avoid variations they dislike, lure opponents into unfamiliar or uncomfortable territory or just worry opponents.^[1][2]

In chess the verb “transpose” means shifting the game on to a different opening track from that on which it started.
