This is an entirely normal trap pass situation that GIB doesn't seem to recognize.

 

"normal?" "GIBBO?" Bet in GIBBO system notes it is a normal takeout double.

It has no sense of negative inferences.

With 1NT showing no fit, there is no other reasonable treatment. This is a clear cut situation of a business double asking for a spade lead.

 

1c/1d/1h-1s-1nt for example by opps and then p-p-x in GIB World asks for spade lead. If 1NT forcing the x is takeout. If not forcing it is not defined since GIBBO won't understand it.
