In the event of a tie, high card is used to set the order. The most common break is a soft break somewhat like a straight pool break where the on coming player has no real shot. The player who is shooting is the ONLY player who can discard as the matching balls are pocketed. If there is a winner established before player A returns to the table, player A's 3 card will count against him. In the game, ONLY balls which match cards in the shooter's hand may be pocketed.
Combinations are legal as long as only the shooter's held balls are made.
The shooter continues to shoot only after a legal or neutral ball is pocketed. A scratch constitutes a single foul which results in loss of turn and drawing 1 card from the unused deck. Scratches are pocket scratches, failure to contact an object ball, not driving a ball to the rail after contact. Pocketing a legal ball and scratching is a double foul which results in a loss of turn and drawing 2 cards form the unused deck. Pocketing a ball which is not held by the shooter is also considered a double foul.
