In serious play, if a player having the move touches one of their pieces as if having the intention of moving it, then the player must move it if it can be legally moved. So long as the hand has not left the piece on a new square, the latter can be placed on any accessible square. If a player touches one of the opponent’s pieces then he or she must capture that piece if it can be captured. If none of the touched pieces can be moved or captured there is no penalty.
