The bidding is as given. Partner's 2♣ bid shows 6+ clubs, ~12-15 HCP, <3 hearts. You feel game should be on (even an outside chance for slam), but which one? 3NT / 4H / 5c are all candidates (it is MPs). What do you bid?
Basically, is the jump 3♥ here GF or invitational? And how should partner respond with a 3-1-3-6 distribution and no spade stopper?
