Playing 2/1 with gambling 3NT and opening one of a minor and rebidding 3NT over a 1 over 1 shows a near solidish suit and stoppers, and 2♥ is NF (2!d is artificial and forcing). What do you make of the 3NT bid?
Do you pull this contract or let it sit? Does your answer change if you think there is some chance partner has forgotten your agreement that 2♥ is NF?
Perhaps, more importantly, what is the best "partnership" bid? If you face what seems like an impossible bid is it better to trust partner knows what he is doing (and in this case pass) or try to save the auction if you suspect partner has messed up agreements (or, hopefully not, doesn't know what he is doing)?
