one who made the first such call shall play the hand, his partner becoming Dummy.

50. When the player of the two hands (hereafter termed the declarer) wins the number of tricks which were declared, or a greater number, he scores below the line the full value of the tricks won (see Laws 2 and 4). When he fails, his adversaries score, above the line, 50 points for each under-trick, i.e. each trick short of the number declared; or, if the declaration was doubled or re-doubled, 100 or 200 points respectively for each such trick. Neither the declarer nor the adversaries score anything below the line for that hand.

51. The loss on the declaration of "One Spade" shall be limited to 100 points in respect of tricks, whether doubled or not.

52. If a player makes a trump declaration out of turn, the adversary on his left may demand a new deal, or may allow the declaration so made to stand, when the bidding shall continue as if the declaration had been in order.

53. If a player, in bidding, fails to call a sufficient number of tricks to overbid the previous declaration, he shall be considered to have declared the requisite number of tricks in the call which he has made, and his partner shall be debarred from making any further declaration, unless either of his adversaries overcall, or double.

54. After the final declaration has been accepted, a player is not entitled to give his partner any information as to a previous call, whether made by himself or by either adversary; but a player is entitled to inquire, at any time during the play of the hand, what was the value of the final declaration.

55. Doubling and re-doubling affect the score only, and not the value in declaring—e.g. "Two Diamonds" will still overcall "One No Trump," although the "no trump" declaration has been doubled.

56. Any declaration can be doubled, and re-doubled once, but not more. A player cannot double his partner's call, or re-double his partner's double, but he may re-double a call of his partner's which has been doubled by an adversary.

57. The act of doubling re-opens the bidding. When a declaration has been doubled, any player, including the declarer or his partner, can in his proper turn make a further declaration of higher value.
