At pairs, you pick up the following hand: S: KJxxx H: AKxxx D: xx C: x You open 1S and partner responds 3NT which, by agreement, shows "a full blooded raise to 4S". In other words, at least four card spade support, 13+ points but no singleton or void. My question is, with this light opener do you sign off in 4S or are you duty bound to cue bid your first round control in hearts? I guess this is a specific example of a more general question. If you are in a game forcing situation should you always initiate a cue bidding sequence if you have a control you can show below game or do you only do so if you have additional strength that makes you think you might be in the slam zone?
