I would never use Capp here. 1. You know what your hand is. It's hearts. Let them find their potential spade fit at the four level. You attack with these hands, not tip toe around like a celebrity trying to dance the cha-cha. :P And bluntly, bidding 3♥ is a wimpy bid that is trying to hedge the playing potential of the hand. Get on with it, 4♥. 2. Tell pard what to do. If you make a single suited takeout, what happens if pard bids your short suit?! 3. Best of all, you know where everything sits. You're red at IMPs, and there is a nice bonus for bidding and making game.
