2♣ is forcing (usually 10+)

I would pass. I might regret it if partner's clubs are internally solid, but I think something like x xx xxx AQJxxxx or x xxx Kxx KQJxxx is not so unusual, opposite which game needs a lot of luck.

3♥, maybe partner will agree to play with a 4-3 fit. I first thought of 3♠ asking for a stopper, but partner rates to have a singleton. Pass also came to my mind, can partner have a real minimum?

[l milne]

Partner rates to have 7 clubs, so 6 cards outside. Of those, we can be pretty sure he is losing a spade, we have 4 tricks apart from that, so unless he has the J♥ or the K♦, he rates to lose 2 tricks outside trumps.

So, some hands where 5♣ could be good:
x xx xxx AKQTxxx
x xx Kxx KQJTxxx
x Jx Qxx KQJTxxx

Some hands where 5♣ is somewhere in between OK and quite bad:
x xx QJx KQJTxxx
x T9x xxx AKQJxx

Some where 5♣ is bad:

It partly depends on your style of 2♣. I play with one regular partner that bidding here can be quite aggressive if we have a good 6+ suit. So x xx xxx AQJxxxx would be completely normal.

That said, there aren't many hands where 4♣ goes off. I would bid 4♣, invitational. We just don't know how good partners hand is; let's involve him in the decision. I don't expect to go minus very often, unless partner is an animal.

Clear pass IMO.
Without interference, 3♣ would be invitationan for me.
With interference it's only competitive.

[gwnn]

just say no

[mfa1010]

Pass. I don't know why you are discussing all those majestic suits. This is really an everyday position. Partner has roughly 10 hcp and a one-suiter in clubs, but it doesn't need to be close to solid.

The Green Card.

This was some sort of ATB, I play NFB normally so not very sure of what I was expected for 3♣.

Seems the consensous is that 3♣ is a huge underbid, I made 12 tricks in 3♣ with

♠x
♥Jxx
♦x
♣AQJ10xxxx

For a funny story, the other table started 1♦-(1NT)-double, all pass, and althou a red lead means 13 tricks for the defence, doubler opted for a ♣Q lead. But when in with ♦A, partner desperatelly underled ♥AKQ to score the rest for +500.

I'm not going to say anything about a consensus, just speak for myself: I think both of you bid this hand well. I don't think that just because you miss a game, one of you must have made a "huge underbid". That 12 tricks were available is really bad luck.
