How do people handle these auctions in 2/1? Interested mostly in systems that have 2S rebids as showing 6+, but if you have the full details of a 2S catch-all type system I'd be interested too.

Hi, I play:
1S-2H-2S min without H fit, 5+ spades, still could be very bad 53H(32)
1s-2H: 4H or splinter 4C/D 11-14
1s-2H-3H: 15+ 3H unbalanced->3S relays: 3NT= extras 18+, 4C/D 15-17 spl with 3H, 4H 15-17 6S3H22
1s-2H-2NT 15+ incl some unbal hands: 3C Relay->
3D=6spades not good for immediate jump,3H=5s3H32/5s4H22, 3S=6S/4H(-3NT asks spl),3NT=15-17 5332h, 4C/D=spl 5s/4+H
1s-2H-3NT=18-19 5s2h33
If 2s always 6+ then just good luck:)

I have specific methods over this auction. But in my methods, the 2♥ response is not game forcing. Having said that:

1♠-2♥ 10+HCP, 5 hearts.

-2♠ Catchall bid, inability to make any other call. Typically a minimum with 5 spades and less than 3 hearts.
-2NT Artificial game force.
-3m Game forcing, natural.
-3♥ Natural, invitational.
-3♠ Natural, invitational.
-3NT To play.
-4m Splinter
-4M To play.
-4NT RKCB in hearts.

After 1♠-2♥-2♠:

-2NT Natural, invitational.
-3m Natural, game forcing.
-3M Natural, invitational.
-3NT To play.
-4m Splinter in support of spades.
-4M To play.
-4NT RKCB in spades.

We also play BART, so invitational hands with hearts and a minor can bid 1NT. Opener's diamond rebid over 1NT promises 4 cards, and he rebids 2♣ as a catchall, allowing responder to use BART more often.

You can just about do everything with 2♠ showing 6 and 2NT as a catch-all, but the lost step does hurt. It flows better if you invert them:

2♠ = various
2NT = 6 spades
3♣/♦ = whatever you normally play them as (I play 5-5 any, but 54+ 15+ fits this scheme)
3♥ = good 3-card raise or 5422 (3♠ asks shape)
3NT = 5233 12-14
4♣/♦ = weak splinter
4♥ = picture

After 1♠-2♥-2♠,2NT asks (the usual bid, but obv not compulsory):
3♣ = nat, whatever range or shape not shown by immediate 3♣
3 ♦ = nat
3♥ = weak 3 card raise or 5422 (3♠ asks shape)
3♠ = 63M
4♣/♦ = good splinter
4♥ = good picture

Yeah we tried playing 1♠-2♥-3m as 54 extras or 55 any, but there doesn't seem to be room to unravel it. You can play 3♦ as a relay over 3♣ but then you lose your fourth suit forcing bid, and you can't do much over 3♦ rebids.

I like the look of your inverted scheme. With the usual 2♠ 6+ and 2NT catch-all, is it a similar scheme just less efficient?

It's doable. You have to play a 3♠ response to a relay as showing clubs, which loses one of the rare hand-types (63M) and is worse when responder was intending to relay before supporting spades or just needed to explore. You also now should play 3♠ over 2NT as showing 5-5+ in ♥ and ♣ but it's otherwise OK except that opener is arbitrarily bidding 2NT on a lot of hands. At least when 2NT shows 6♠ you usually belong in 4♠ anyway.

fwiw I play 2s as 6+ so:
2nt=you assume pard has minimum 11-13, natural
3c or 3d are natural but not extras again you assume pard has 10-13.
With 17+ opener will bid again.
That means the two suited hands in the range of 14-16 may cause you a problem. In practice this has not been a big deal but you can come up hands in this range that will cause an issue. Again because for me a2/1 shows a pretty darn good hand opener will very often have less than responder and responder assumes such. Also please note this approach throws some, hands in a SF 1nt response, again not that big of an issue but one to be aware of.

I'm worried to see that we've developed something similar to Phil's scheme. Luckily it's sufficiently different we won't have to play royalties.
We don't usually open 1NT with 15-17 with 5 spades but open 1S

1S - 2H -

2♠ = various, might have 4-card heart support
2NT = 6 spades, usually not 3 hearts
3♣/3♦ = natural, decent 14+ HCP, 5 cards
3♥ =15+ HCP with 3 hearts (artificial continuations) or 4 hearts and no shortage
3♠ = extra values, sets spades as trumps
3NT = 5233 15-17 (responder's continuations transfers)
4m = splinter, good 14+ HCP
4H = 5422 11-13
4S = undefined (technically it ought to be keycard in hearts according to our agreements but I doubt we would dare)

1♠-2♥-2♠-
2NT = relay (virtually every hand asks)
3♣/3♦ = 6-5 or possibly a very concentrated 5-5, natural
3♥ = sets hearts as trumps
3♠ = sets spades as trumps
others basically don't exist (I could construct possible hands)

after 2NT asking
3♣/3♦ = natural, 4 cards any range or 5 cards min
3♥ = 3 card support or 4 hearts and no shortage (3♠ asks)
3♠ = 12-14/18-19 5233
3NT = 6-3 majors, forcing
3m = 54 majors, splinter, min HCP

There are two routes to 3♥, but continuations are the same except the ranges are different
3♠ asks, then
3NT = balanced
4m = splinter, 3 -card support
4H = 5422
4S = keycard

It's based on a Crouch thing from the late 1980s (but for all I know, it may pre-date the Cantabrian cave paintings) - I started playing it with Hobson in 1989.

[lmilne]

Does anyone have experience with 2♠ showing 6 and 2NT/3♣ being transfers? Would this structure work?

I also play something similar to this. How do you show 18-19 balanced as opener? I think we would bid 1♠-2♥-2♠-2NT-3NT but this puts the strong hand on the table. Perhaps this is the main disadvantage of using 2NT to show 6 spades.

EDIT: Actually how about switching it up and using 1S-2H-3NT as 18-19 and 1S-2H-2S-2NT-3NT as 12-14?

[Winstonm]

In 2/1 the 2NT rebid can handle 12-14 + 18/19. 1S-2H-2N-3N-P-12-14 and 4N=18/19

Well yes, but if you actually read the scheme above, 1S-2H-2NT is artificial showing 6+S.

The OP stated, "Interested mostly in systems that have 2S rebids as showing 6+, but if you have the full details of a 2S catch-all type system I'd be interested too." I thought I was addressing that question.

Yep. That's what I do. I can only assume I was on hallucinatory when I said the jump to 3NT showed the weak NT.

i play 2／1 forcing game！2s is 6+suit
2nt balanced！12-14
3c 3d （not balanced single or void h）
3h（17+，balanced）
3s 4c 4d splinter 15+
3nt（19+ balanced）
4h（12-14！or 12-16 balanced）
tansfer 2／1 respond may better！
