Petit Au Bout
When the last trick is won with the Petit (1 of trump), 10 points is added to or deducted from the hand score before multiplying. Whether it is added or subtracted depends on which would most benefit the side making Petit au bout (One at the End). Usually, when one side (taker or defense) makes Petit au bout but the other side was successful in either making or breaking contract, the bonus is subtracted; when one side is successful in the contract and also makes Petit au bout, the bonus is added. If the side attempting the Petit au bout wins all the tricks, the player gets the petit au bout bonus if the Petit was played at the second to last trick (and won the trick) and the Fool was played at the last trick. This bonus is multiplied according to the contract; if the contract is Guard Without, the gain or loss for a single hand score is adjusted by 40 points one way or the other.
