Considering that you are off the ♥A, a sure diamond trick (possibly more) and the ♣A, I would say that I would NOT want to be in 5♣.

On the other hand, you have a sure diamond trick on defense (if you don't then you may have 3 diamond losers on offense) and two sure trump tricks. In addition, the ♥K may score a trick on defense.

All in all, I don't see why you want to be in 5♣ (presumably doubled).

The best likely result in 5♣x is -200 against -620. But you could easily be -500, and possibly -800. Meanwhile, you might beat 4♠.

There is one other possible upside to bidding 5♣ - the opps might bid 5 of a major, which you will almost certainly beat.

I think west should bid either 4N or 5C.

He has a double fit, 5m cant go off that much, and may even make.

jmoo.

Opener does not expect the surprise. With 3-2 in the majors, it seems fairly reliable, when South jumps to game in spades, to expect partner to have longer hearts than spades, probably either 2♥/1♠ or 3♥/0♠, probably the latter. Opener would be logical in assuming that South has something like Ax or Kx in hearts with four or five spades, probably five. Because of the lack of spade values, it seems like the opponents probably have one of the minor Aces for these two bids.

So, it looks like maybe the defense of 4♠ will include two spades and a minor Ace. The Question will be whether a second minor card will cash. If dummy has 11 cards in the majors, the contract looks to make. This seems close.

Assuming, however, that partner has the expected two heart losers, with the A-K in spades only contributing a single trick at best (per fair assumptions), Opener needs a lot from Responder to make 5♣ a good save. That minor Ace is good for a one-trick set, and there may be an easy ruff, even if Responder has the rest of the values.

In sum, I don't think Opener should bid here.

Responder. With a likely surprise in hearts and an Ace, I'd be more likely to double than to sac.
