At this level opposite a passed hand? I suppose, maybe, but if you're really playing him for that, shouldn't you be saving? Can you give me an example hand? Everyone disagrees with me but I really don't see it.
I agree completely with the abstainers but since I am here I am bidding 4♣. I thought about 5♥ but decided I didn't want to make two knucklehead bids on one hand.
I'm having trouble coming up with possible hands for partner but I could hardly have better cards on the auction. He must have a hand that was too good for 4♥ over 3♠.
If partner has what I expect, 6-5, then I don't think we can beat 4♠ and I plan to bid 5♦ if they bid it. Partner will know that I have 4-4 since with only 3 hearts and a bad hand I would have just raised diamonds.
Partner has a diamond stack and a good hand, could be short in hearts. This is not the sort of auction where you balance vul with a light takeout double.
