multi-def double

[1eyedjack]

Here is another example of how GIB is seemingly incapable of coping with a t/o X of 1-suit based on multiple hand types.

MP, best hand South, instant, pro GIB 30.

 

Focus on East's 4H.

 

So far (immediately prior to 4H):

West has clarified that his X was based on a strong Club overcall, for which Heart support is not a requirement.

South has shown 21 HCP

N/S are in a partscore

East has already shown some Hearts (granted not 6 of them)

 

Your call.

OK I can forgive Gib for thinking to rebid it's magnificent 6-card ♥ suit but where does Gib get 7-9 pts from?

 

If Gib had 7-9 pts like A♥ instead of 2♥ you might actually make 4♥
