Green - IMPs

(1C*)-2C*-(2S*)-3H

West opened 1C (prepared, could be just 2). North overcalled 2C. This was natural because their 1C only guaranteed 2: if it guaranteed 3, then 2C would have shown the majors. South thought the opps bid showed 3+ so he alerted and explained it as the majors when asked. East bid 2S (alerted - North/South did not remember the explanation).

South bid 3H

The explanation for only bidding 3H was:

There is no need to bid to the level of the fit (4H) because the opps "clearly" don't have a spade fit (we have 3 plus a theoretical 5) and I wouldn't want to bounce them into a likely making 5C contract?

Should we be happy with this explantion?

Does it matter? It seems unclear which law you think NS have infringed here. South has no UI (unless North kicked him under the table when he alerted 2C).

Sometimes at the table partner reacts when something is alerted that they weren't expecting. I'm not saying this happened here, but 3H seems very pessimistic at these colours, given the side support of Axx for partners other suit. So, perhaps I should have asked how strange does a bid have to look before there is any redress. Maybe there never is.

[bluejak]

If there is no infraction then it does not matter how strange a bid is: it is legal.

Yes, there was MI, but that is not relevant to his choice of call.

The infraction if there was one would have occurred next, what was the 2♣ overcaller's hand, what should he do over a natural freely bid 3♥, it's him who has the UI that partner has misunderstood his 2♣.

Yes, I would like to know the rest of the auction and partner's hand.

Full auction was:

P - (1C*) - 2C* - (2S*)
3H - (3N) - P - (4S)

The other hand was:

4
94
QT982
AKT86

Arguable if this hand should double 3N and/or 4♠, but if he's expecting say a 10 count opposite (for a free bid of 3♥) maybe.

What was led ? Did they beat it ? (club lead looks to have a good chance of beating it).

I think when 4♠ is bid, N can pretty much discount his partner holding majors and lead what he likes.

Do you mean S?

Also anyone expecting 10 points for a free bid has never played with my partner Doubling 4S looks very gamble-y.

Yes I do mean S.

(1m)-2♣(nat)-(2♠)-3♥ shows a decent hand for most people, and the hand appears to be a misfit.

[sailoranch]

The MI from South's explanation could have derailed East-West's auction, since the meaning of 2♠ is likely dependent on the meaning of 2♣. It seems like East wanted 2♠ to be natural, but West thought it was strong with diamonds and bid 3NT with the majors well stopped. East corrected, either after the UI from the alert or from knowing that 2♣ was natural. (Screens, maybe?)

It's hard to judge what might happen without seeing all four hands. But West would probably rethink 3NT, and maybe North, presumably in a force, will have to drive to a terrible contract.

[mycroft]

Apart from the fact that without UI or CPU, South has no restrictions, 4♥ almost always loses all 3 minor tricks, and even with ♠KQ ♥A we are nowhere near a lock to run both majors; I would expect to go down in 4♥ as often as I make it. And they're not making anything - maybe 4m? Maybe? So why bid 4?
