Tell me your auction
South Dealer

[kenrexford]

This is a tough question to answer, because I do not know who I am and because I do not know what people will do.

If I am in all seats, playing 2/1 GF:

1♠-P-1NT-2♥
X-P-3♣-all pass

That seems likely.

I mght as West make things ore interesting with one of two options. First, I might make a traditional "RUNT" 1N weak takeout. This would give East cover to compete to 3♥. Alternatively, West using "Son-of-RUNT" mike make a S-O-R Double, with the same end result.

If South uses Canape ala MICS, he opens 2♠ to show spades and clubs. Things get muddy and interesting after this, but North might even end up in 5♣, which is a lot easier payed by North (no problem with a diamond lead).

Well the start's easy enough, but things get interesting after we get back to South. Here's what four of me would do (I play a variant of Acol) playing MPs all white.

1S-p-1N-2H
X-p-3C-X (just)
p-3H-p-p
p

We're not told the vul or scoring, which will almost certainly make a difference. For example, all white at IMPs South might try 4C instead of his final/second-to-last pass. If East is vul at imps he's not going to X on the second round.

And no, I have no idea how to get to 5C.

Why would South pass 3♣ on the given auctions?

Why would North bid 3♣ if it was passable with South's hand when partner is offering to play in the minors and he has such a good minor?

My logic was that South can't really envisage 3NT opposite a <=9HCP response given his distinct lack of a heart stop, and North doesn't want to go past 3NT because it may be on if partner does have a heart stop. This is one reason why I'm not convinced my partner's style of "X even with a minimum opener, if short in opps suit" is a good one.

You have a point though; perhaps North might try 3H.

Playing our slightly bent form of weak no trump acol, N is just about worth a 2/1 so:

1♠-(P)-2♣(10+ with 4♣ or 9+ with 5)-(2♥)
2N (GF, not necessarily balanced or heart stop)-(P)-3♣-(P)
4♣-(P)-5♣

1S p 2C 2H
4H P 5C all pass

tough maybe:

1s=p=1nt=(2h)
x=p=3c?=?
4c?=5c

so might get to 5c...might not.

If my system is used in all seats:

W - N - E - S
1♠
/ 2♣ 2♥ X
3♥ 3♠ / 5♣
/ / //

[Zelandakh]

Well the start is easy - 1♠ - (P) - 2♣ - (2♥), where 1♠ is unbalanced and limited to 17 and 2♣ is natural, non-forcing, possible canape and denies 3 spades. After that probably 3♥ - 4♣ - 5♣, although at IMPs going directly to 5♣ would be tempting. It is hard to see how South can avoid getting to 5♣ after hearing 2♣ from North and 2♥ from East, whether the 2♣ shows 9+, as in the Acol sequences, or less than invitational, as here. Obviously it is very different for those that have to start with a 1NT response.
