Support Double and SUPPORT REDOUBLE

 

Situation: Your partner opened 1§.  You have a 5 card Heart suit with an 11 HCP hand and bid 1©.  Your LHO then bids 1ª.   [1§ – P – 1© – 1ª . . . ].  Opener is faced with raising your Heart bid with ©Axx or not.  If you have ©Jxxx, 2© is the wrong call.  If you have ©KJTxx, it’s the right call.  What’s the answer?

 

Solution:  A Support Double solves this problem very nicely.

 

A double after a 4th seat bid shows 3-card Heart support.  [1§ – P – 1© – 1ª   Dbl . . .].

 

Now you have found an 8 card major suit fit and you can bid on intelligently.    

 

Any other bid by opener denies 3 trumps.  [1§ – P – 1© – 1ª    1NT . . .].

 

With 4 trumps, she would raise, of course.

 

If 4th hand doubles instead of bidding a suit, opener can Redouble to show a 3-card fit.

[1§ – P – 1© – Dbl   Redl. . . ] As before, any other bid by opener denies 3-card support .


Support Double Sequences:
 

 [1¨ – P1© – 2§       2¨ . . .]    “I don’t  have 3 Hearts but I do have 6 Diamonds”
 [1
¨ – P 1© – 2§      Dbl* . . . ]  “I have 3 Hearts for you”

 [1§ – P – 1ª – Dbl      Red* . . .]  “I have 3 Spades for you”

 

Summary: A Support Double or Redouble can happen only over a sequence that starts

[1-of-a-minor – Pass – 1 of-a-major – bid by 4th seat - . . . ]

 

Now, opener’s 2nd call can be a Support Double or Support Redouble.  If 2nd hand bids, responder’s Heart or Spade bid naturally shows 5 cards, so the need for a Support Double or Redouble is no longer necessary because opener then knows to raise with 3-card support. 

 

[1§ – 1© – 1ª – 2© . . . ]  In this example, a double is for penalty or an Action Double, not a Support Double, because opener knows 3rd seat has 5 Spades, having b id over opponent’s overcall.  Responder shouldn’t bid a 4 card Spade suit in this situation; instead she should Negative Double to show 4 card suit(s), especially Spades.

 

Resolving Confusion between Support and Action Doubles: If opener’s double could be a support double, showing 3-card major suit support for responder’s suit, then it is a Support Double and not an Action double.

 

          [1§ – P – 1© – 1ª   Dbl . . .]      This is a Support Double, not an Action Double.   

[1§ – P – 1¨ – 1ª    Dbl . . .]  This can’t be a Support Double, so it’s an Action Double
