In matches in which three players play against each other, each playing his own ball (hereinafter referred to as "a three-ball match"), or in which one player plays his own ball against the best ball of two players (hereinafter referred to as "a best ball match"), the Rules of Golf shall apply, subject to the following modifications:—
1. Where, in a three-ball match, at any teeing-ground no player is entitled to claim the honour from both opponents, the same order of striking shall be followed as at the previous teeing-ground.
2. Except as hereinafter provided, the side whose ball is furthest from the hole shall play first, but a ball lying nearer the hole and belonging to one of that side may, at their option, be played before the ball lying furthest from the hole. If a player play when his opponent should have done so he shall incur no penalty.
3. If a player consider that an opponent's ball on the putting-green might interfere with his stroke, he may require the opponent either to lift or to hole out his ball at the opponent's discretion.
4. If an opponent consider that the ball of another opponent might be of assistance to the player, he may require that it be either lifted or holed out at the other opponent's discretion.
5. If an opponent consider that his own ball might be of assistance to the player, he is entitled to lift it or hole out at his discretion.
6. If an opponent consider that the player's partner's ball might be of assistance to the player, he may require that it be either lifted or holed out at the player's partner's discretion.
7. In a three-ball match, a ball on the putting-green, which is moved by another ball, must be replaced as nearly as possible where it lay.
8. In a best ball match, if a player's ball move his partner's ball or an opponent's ball, the opponent shall in either case decide whether the moved ball shall be replaced or not.
9. If in a three-ball match a player's ball strike or be moved by an opponent or an opponent's caddie or clubs, that opponent shall lose the hole to the player. As regards the other opponent, the occurrence is "a rub of the green."
