GIB endplayed itself by bidding 2♣ without being programmed to bid 2NT with no spade stopper or raise hearts. Rebidding clubs was probably higher priority in the programming than rebidding 3♦.
I admit being endplayed is a nasty thing
yet I believe GIB should stop rebidding 4-card suits. Just a few days ago I encountered a similar problem which I posted here:
http://www.bridgebas...deal-with-this/ In that case robot rebid a suit with a bid labed "5+ cards" but it had only Txxx. This ended up with the majority of players playing that suit in a 4-2 fit going down 4 or 5. Alternatively GIB could have bid the 4th suit or passed.
