53. The effect of doubling and re-doubling, and so on, is that the value of each trick above six is doubled, quadrupled, and so on.

54. After the trump declaration has been made by the dealer or his partner, their adversaries have the right to double. The eldest hand has the first right. If he does not wish to double, he shall say to his partner, "May I lead?" His partner shall answer, "Yes," or "I double."

55. If either of their adversaries elect to double, the dealer and his partner have the right to re-double. The player who has declared the trump shall have the first right. He may say, "I re-double," or "Satisfied." Should he say the latter, his partner may re-double.

56. If the dealer or his partner elect to re-double, their adversaries have the right to again double. The original doubler has the first right.

57. If the right-hand adversary of the dealer double before his partner has asked "May I lead?" the declarer of the trump shall have the right to say whether or not the double shall stand. If he decide that the double shall stand, the process of re-doubling may continue as described in Laws 55, 56, 58.

58. The process of re-doubling may be continued until the limit of 100 points is reached—the first right to continue the re-doubling on behalf of a partnership belonging to that player who has last re-doubled. Should he, however, express himself satisfied, the right to continue the re-doubling passes to his partner. Should any player re-double out of turn, the adversary who last doubled shall decide whether or not such double shall stand. If it is decided that the re-double shall stand, the process of re-doubling may continue as described in this and foregoing Laws (55 and 56). If any double or re-double out of turn be not accepted, there shall

be no further doubling in that hand. Any consultation between partners as to doubling or re-doubling will entitle the maker of the trump or the eldest hand, without consultation, to a new deal.

59. If the eldest hand lead before the doubling be completed, his partner may re-double only with the consent of the adversary who last doubled; but such lead shall not affect the right of either adversary to double.

60. When the question, "May I lead?" has been answered in the affirmative, or when the player who has the last right to continue the doubling expresses himself satisfied, the play shall begin.
