Bidding script: EW do not bid

An advertisement for supporting responder’s Major with 3 cards, this hand will surely see many ‘modern’ pairs reaching game or any contract in spades. In the past without checkback and with evaluation a little stiffer it was hard for South to invite, but I think this will be reverted. 4S, 10; 3S, 6; 2h, 4; 3h/3D/4h/1NT, 2"

1♥-1♠
1NT-P

Fooled by the standard bidding contest question of "stay low and in NT or miss game?"

I raised to 1S mainly because han likes that style. Personally I think if you play some kind of 2 way nmf or whatever and you can invite with the south hand and stop in 2S that would be fine like:

1H 1S
1N 2C
2D 2S

The south hand really looks like it will play better in 2S than 1N to me anyways, so even if you won't invite I think 1H 1S 1N 2S is fine.

I don't remember what I did on this hand. North opens a weak NT (11+-14), I'm sure I transfered, but not sure if I invited.

Would you invite with the South hand after a weak NT?

[hanp]

After Justin's 2S it was a bit of a guess. I couldn't make a natural 3D invite so I asked with 2NT. Justin showed a maximal hand with 3-card support and no shortness Change the minors and 4S is not a good contract and there was no way to tell, I guessed to bid 4S.

Since it was a bidding contest I was keeping the option of 3NT open. Had Justin shown a maximum with 3 spades and short diamonds I would have tried that.

[JLOGIC]

You bid 3N? I thought we bid 4S lol

[paulg]

According to the official record you bid:

1H 1S
2S 2N
3D 3S
4S P

I'm not convinced that the South hand is worth an invite at matchpoints. Swap North's minors and you really want to be in 2♠ and when North has four spades he will be pretty minimum.

Uh yeah of course, was already thinking about what to write next.

I think this one went

1N - 2♥
2♠ - P

I think that the hand is close to an invite, but I would probably pass 2♠

[hanp]

Seems right to pass opposite a weak notrump.

If you could bid 2C then 2S showing a light/distributional invite that has no interest in 3N I think that is good.

Believe it or not, my preferred system over NT openings (Scanian) uses just such a response.

Sadly, responses over 1NT are the least developed part of the system we're using for the contest...

[Wackojack]

The system is to open all 5332 hands 1NT in the range 14-16. I was close to doing this with the North but instead decided to show 5 hearts by responding 2D. We would open this 1H with 10-16. So the bidding went:
1♥ 1♠
2♦ 3♦
4♠

Partners raise to 3♦ encouraged me to show extra strength by jumping to 4♠. Partner (who's system it is) told me off for not opening 1NT

Scoring
4S = 9
3S = 4
1N = 2

[cherdanno]

So I believe one shouldn't raise after 1H 1S with 35(32) hands - this auction is different to 1m 1M, since we usually can't have a weak NT for our raise, and so our partner won't play us for one, and so our hand would just be way too different from partner's expectations.
So I stuck to my convictions, and we bid
1H 1S
1N 2C
3S.
Roger reasonably passed - usually game would be on a finesse; it could be cold with my actual hand, or have no play (switch the minors and make the hearts KQJ2), and with my actual hand I might have raised. He would have been right on a 1m 1M auction.

[cherdanno]

My scoring for this hand would be, for (4S, 3S, 1N):
Matchpoints:
4S goes down (Spades 4-1 with no elopement, or diamond ruff): (2.5, 12.5, 7.5)
Spades break and no diamond ruff: (12.5, 6.5, 1.5)

The weighted average would be s.th. like (9.5, 8, 3.5) - here I assumed the first one would happen 1/3 of the time, the latter 2/3. Then you scale and get scores. So it looks to me the difference between 4S and 3S is too big, due to the number of 1N contracts.
(I might be wrong about the numbers, i.e. my 1/3 might be off, but I wonder whether Ben agrees with the principle.)

Yes, if we had that agreement I'd definitely do it. But we don't, so it's either transfer and pass, or transfer followed by 2NT which didn't seem appealing to me.

I don't think partner will be disappointed when you raise with this 13-count.
