Vulnerable against not, you pick up in 3rd 1st seat a nice 17 count. You open 1♦ and partner responds 1♠, what's your rebid?

This is not a game force, therefore I bid 2♣ which if partner passes, is unlikely to be better than a finesse for game unless partner has something like xxxxx, xxxx, K, Kxx.

[CSGibson]

2♣. partner should make a false preference to 2♦ with a non-minimum and 1 less diamond than club (assuming its right to give preference instead of rebidding spades). I can then bid 3♣, which should be a 5-5 hand in the minors which would have jump shifted with (up to) another king in playing strength.

[broze]

Interesting. One of those hands that I would auto-jump shift after 1♦-1♥ but after 1♠ perhaps 2♣ is enough (though I would still jump at teams since my partnership is not forced to game and has a good system over jump-shifts).

Your bidding sequence is wrong. It says in 3rd seat you pick up a nice 17 count. By inference you state that partner is already a passed hand. For that reason alone, my next bid is 2♣. If partner was an unpassed hand, I would venture 3♣.

I voted “something else” here. With 5-5 in the minors and 14-18 HCP, I open 2NT telling partner that I have no real interest in playing anywhere else except in a minor.

This is what my continuation bidding structure looks like with these sorts of hands:
a) Pass = both majors and no fit in the minors. If 2NT makes, you score 120 where the rest of the field scores 110 or minus 50.
b) 3m = suit preference, signoff
c) 3M = 6-card suit, inviting 4M if opener has 2-card support
d) 3NT = to play, both majors plus values
e) 4m = Minorwood for the suit bid, slam interest
f) 4M = to play, 7-card suit plus some values
g) 5m = to play, distributional fit, cross-ruff potential

[aguahombre]

Delightful, but he asked about the rebid after opening 1D.

1D-1S
?
you rebid something other than the choices in the poll? It is slightly better to offer your answer under the conditions, and then go off on your gadget.

I choose the 2C rebid.

Sorry, the diagram was right (1st seat opener).

[ahydra]

Too light for 3C for me. I'll go with 2C.

[Quartic]

At the table I chose 2♣.

Our agreement is that 4th suit is game forcing.

[aguahombre]

On the follow-up with that one, IMO 2NT under the conditions (we have same conditions).

If partner is accepting the invite with 3S, she will bid them enroute. If not, oh well.

[Codo]

I would understand the overbid of 2 ♥ but I would rate 2 NT as obvious.
With both hands visible, I would be able to reach 6 ♣.
But at the table, I guess I had played 3 Nt like most others with these hands...

3N with the first, 2N with the second.

Over 3N I would bid 4♣ every day of the week at teams, trickier problem at pairs.

If 3♣ is forcing over 2N I would bid it (I play a non GF 2♥ which I would probably bid and not sure what if any difference this makes).

[Quartic]

My partner chose 2♥, then unfortunately passed 3♣ (clearly wrong). I wasn't certain our other bids were optimal though. I made 11 tricks in 3♣, while the field were making 3NT. The full hand:

6♣ isn't makeable (double dummy), but I'd have preferred to try than to stop in 3♣.

Your partner doesn't play 2♥ FG, I might pass 3♣ too, where do you want to be opposite x, xx, KQJxx, Axxxx which is what you might have shown if 2♥ wasn't GF.
