I did not know GIB did this. Very interesting bid. GIB did this at each table.

To initiate Stayman with garbage hand GIB needs 4450 shape.

Here default rebid for GIB is 2NT instead of pass, but simulation showed somehow that pass is also an option.

I think that I approve.

It may run counter to the way that the human mind works, but I think that statistically it may well be reasonable for responder a priori to have a game try opposite a 1N opener and yet on the balance of probabilities to prefer 2D over a further game try after the Stayman response.

Correcting 2H to 2S to show 4 spades (NF but invitational) is certainly a good treatment.
