Zugzwang is the german term for compulsion to move, referring to a position where a player is not menanced until he is forced to take his turn and move (i.e. would prefer to pass and not move if it were legal in order to avoid damaging his position). Continuing from the line above, after 38. Re5! b6 39. h3 c5 40. h4 h5 41. Kg2 Black, who would prefer not to move if it were legal, must now take his turn and is compelled to make an abvious losing move
