Definition: Switch can be a tournament format or a betting game. Either way, it involves 2-person teams on which the players switch balls following the tee shots, then play out the hole using those balls.
For example, Players A and B tee off. Player A now switches to B's ball and vice-versa. Player A continues playing that ball he's switched to until it is holed, as does B.
Switch can be played as stroke play or match play; the total strokes for both players can be used, or just the better ball of the two.
