I’m surprised that only one previous poster suggested that opener should bid 2N over 2H. I think that it’s automatic to do so.
Then south, knowing that opener is probably 1=3=5=4, since with 2=2=5=4 he’d rebid 1N with hearts stopped (depending on style, some might be 4=5 minors), responder should rebid 3C. Bidding 3S, over either 2N or 3H, shows 6 good spades, still interested in a spade contract, up to and including slams, despite the known shortness.
Opener has a bad non-minimum with no Aces, so should try to slow things down via 3N and then south, who does have the aces, has to make a decision. Since x Kxx Kxxxx Kxxx has some (poor) play for slam and opener has more than this, I can’t see passing. I’d bid 4D to force a 4H call from North. If North can’t bid 4H, then we’ll play 5C...after all, the best hearts opener can have are QJx, and if he has Qxx we’re likely failing in 4N.
Over the 4H cue we’ve coerced from opener, and absent special agreements, I’d just bid 6C. If opener has x KQx KQxxx Qxxx, we are likely going down, but neither life nor slam bidding comes with guarantees.
JB: there are times when it is correct to pattern out with some 5431 hands, showing the 3 card suit along the way.
Say one held AKxxx x KQxx Axx
1S. 1N
2D. 2N
Now, especially at imps, one can bid 3C. After all, responder might hold something like xx A10x Jxx KQJxx
It would be a shame to play 3N down on a heart lead while 6C is a decent contract.
But when opener could be 1=4=4=4 or 0=4=5=4, and responder could have 4 hearts, it’s a mistake for opener to pattern out with only 3 cards in the 3rd suit.
