الوصف
Marty Bergen, the ten-time US National Champion, covers the hands which are ideal for the negative double, those which are imperfect but still qualify, and those which you must not double. Also included are aspects of hand valuation, opener's replies to the negative double, rebids by the doubler, and when to play for penalties.
