I'll try 5
♦. I expect that the 4
♥ bidder holds several small diamonds, and the information that we have a real fit in diamonds upgrades his hand (he knows he will not lose the first several diamond tricks). I'm not convinced at all that 4
♥ will go down; in fact I expect it to make.
The question I'd ask here is, what does partner have for the 4
♦ call? Partner couldn't raise 2
♦ immediately, despite the fact that this would be a mostly obstructive raise (surely 2
♠, and likely even 2
♥ and 2NT are available as stronger raises; 3
♣ might even be a fit non-jump). My guess would be that partner has something like
♦Kx and some club cards, and that 4
♦ is a constructive bid and not just pushing for a partial. A possible set of hands:
Sure this is a sort of extreme situation, but everyone has their bids. Most people open the east hand, north doesn't really have a clear call after the double of 2
♦ (only eight high, only two diamonds, only four clubs). West bids 3
♥ competitively because of five card support, and the well-placed spade ace. Partner feels compelled to take a call at second turn since you've shown a pretty good hand and now he knows there's a real fit. East passes because he figures partner will know he has shortage in diamonds and be well placed to double if he has a diamond card or two and we're going down. West looks at his four small opposite east's marked singleton or void and takes the push. Notice that 5
♦ and 4
♥ are both going to make. [EDIT: Okay, I take that back; only 4
♥ is going to make and 5
♦ will be one down, unless partner has actually KJ tight of diams]
While the hands may not be this extreme, I think on the auction it is likely that one of 5
♦ and 4
♥ is making, and the other goes at most one down. I'll compete. Who knows, maybe opponents will bid 5
♥ and give me an easy double?
