Hi All,

Playing SAYC with a pickup partner...

Scoring: IMP

1-P-2NT-P
?


What should be the correct rebid, how much is this hand worth (17 / 18)?

Ty all

I think this is an above-average 17. 3NT is the normal bid to show this hand.

Would you consider upgrading to show a 3?

3 shows a good hand with extra trump length but no shortness (or improvising with 18-19 balanced, but anyway, I do not think this hand is good enough).

I don't know standard Jacoby well but what rogerclee says is new to me. I thought 3S > 3NT > 4S, I didn't think they showed different kinds of hands.

I would have opened 1NT with this hand.
Please note: I am interested in boring, bog standard, 2/1.

And I thought 3 shows a hand with 16+ hcp and no shortage. Is there a thing such as Standard Jacoby I wonder. At least there seems to be lots of variations.

Not sure if standard, but at least what is in the ACBL SAYC notes...

Quote

* If responder jumps to 2NT over a 1 or 1 opening, that is Jacoby 2NT, asking opener to show a singleton or void. If opener has no short suit, he shows his hand strength;

1 — 2NT

3, 3, 3 = singleton or void in that suit. Other bids deny a short suit.
4 = minimum hand.
3NT = medium hand (15–17).
3 = maximum hand (18+)
4, 4 = 2nd suit

If we decided the hand was too strong to open 1NT, then in your system I would now bid 3.
That's impossible. No one can give more than one hundred percent. By definition that is the most anyone can give.

Interesting to find out that I have been playing a nonstandard version of Jacoby 2N all this time, which I thought was standard :).

Hi from BWS 2001...

Quote

After a two-notrump forcing raise: a simple new-suit bid shows shortness, a new-suit jump shows a two-suiter, and the three other game-and-below bids (simple same-suit rebid, three notrump, jump same-suit rebid), herein called TOBs, deny the requirements for any new-suit bid. The TOBs are graded from strongest to weakest (cheapest bid is strongest).


Seems to be in the same wave than the SAYC Notes...

This is news to me.

I always thought that a rebid of 3 of the major and 3NT were both strong but showed different types of hands, not different strength hands. 3NT indicated a lot of honor cards outside of the trump suit and a rebid of 3 of the major suit showed a strong suit with fewer honors outside.

I will have to discuss this with my various partners to see what their understanding is.

I was first taught, 4M=11-12, 3NT=13-15, 3M=16+ all with no shortages. So I will now bid 3S =). I would also open this 1NT.

That is the way I learned it. I'm going to treat this as a maximum (3).

If you are in a pick-up partnership, and you do not know which way partner plays, and it is a close call anyway, use the cheapest option. Here, that is 3.

This is a routine 17 count due to the Jx of so take your choice of 3 or 3NT depending on your range for them.

If PD Q's 4 you'll be happy to cooperate with 4, IMO. If he can't show you a control, you can rest safely in 4.

Haha wow and I thought what roger did, that 3 showed extra trump length and 3NT showed balanced, both with extras and no shortness. I am not the least bit put off by learning that I didn't know the standard responses to jacoby.
Please let me know about any questions or interest or bug reports about GIB.
