 You are at: Home > T > Thrump Double: Bridge Bidding Convention

 

Thrump Double - Derived from the words "THRee  notRUMP", a specialized use of 3N useful after partner opens and Right Hand Opponent makes a preemptive 3 level bid (3D through 3S). When responder does not have a biddable 5 card major or a stopper yet holds at least 10 points, the Thrump Double allows game exploration.  Note: if opener began with a major suit, responder's Thrump Double denies 3 card support.

After responder makes a "Thrump Double"; here is an example illustrating opener's possible rebids:

1C - (3D) - X - (P);    Thrump Double
 ?

Meaning

3N

3H
