After 1 heart by right hand opponent, X by me, pass by Responder, jump to 3C by Advancer, pass by Opener, 3S rebid by me described as 14+ (when it should be more like 18+) GIB passes. His hand is K107 5 J642 AJ1053 = 9 plus the heart singleton. We easily made 5 spades but were passed-out in three. Please correct GIB's programming to understand that doubling and then bidding a suit shows a strong hand.
