2S
does opener 2s rebid promise 4 card spade, or just shows spade stopper ?
for example, opener holds
S: KJT
H: xxx
D: -----
C: -----
1D - 2C;
? does opener bid 2S, or something else, such as 2D, 2N..?
btw, i didn't see BBO advanced system covering the 1D-2C topic yet.
thanks,
Barid,

AQ10x x AQJxxx xx seems enough for a 2S bid to me.

Ha
I can live with
AXXX=XX=AQXXX=XX
1d=2c=2s
I would post even worse hands but this is a family channel.

1) denies balanced hand (2NT and 3NT rebids no matter what stoppers I lack)
2) promises stopper (If I happen to have very long diamonds, I will run from 3NT later)
3) does not necessarily deny heart stopper (4-3-5-1 or similar)
4) does NOT promise any extras.
I don't ever play 2/1 as 10+, but I would probably treat it the same way.

There are all kinds of treatments, which shine on some hands and look bad on others.
For what it is worth, and this is relatively simple, I often play:
2♦ is a noise: shows nothing at all, except that it denies the ability to make any other bid
2♥/♠ show 4 cards and longer ♦ and extra values... I would evaluate the hand as a King above my minimum playing strength as opener. I would upgrade hands with a partial ♣ fit, for example: possibly leading to a very informative auction such as 1♦ 2♣ 2♠ 2N 3♣... showing a goodish hand with 4=1=5=3 shape and allowing for a good slam on sometimes borderline hcp.
2N is a positive move, with both majors stopped. Bear in mind that I frequently play weak notrump, so then the 2N is bigger than a 1N opening. If playing 15-17 1N, 2N = 13-14. I do not try to hog nt when I open 1♦ with a 3=3=5=2 or 3=3=4=3 11 or 12 count.
3♣ shows real support. If only 3 cards, then real extra values... but with that hand, I may have other bids, so it usually shows 4+ support.
Over my 'noise' 2♦, responder bids naturally. 2 Major is bidding shape, and allows us to back into a 4-4 fit. 2N is forcing (I play 2♣ as unconditionally forcing to game) and allows for natural 3 minor rebids from opener.

In the meanwhile, the method i am attributing to fred (hope i remembered it right), is from Eric Kokish and is frequently called kokish rebids, and can be found here....

If you are playing a pure mafia style this has some logic, I suspect most here are not playing Mafia, perhaps not even Walsh. (AI_U_Card excepted.)

Well, doesn't that get you into the usual problem of 1D-2C-2D = anythng from 11 to 20?

Thanks, I appreciate the exception. The reference was for the 1D-2C not being a game force. Using std methods I would expect the 2S rebid to be a "true" reverse and absolutely force the auction to game.....

thanks ben, the link is very helpful.
and actually my intension of 1d - 2c is not GF, due to 1D - 3C as 8-10 Diamond raise unbalance hand.
so responder inv. hand has to go through 1d - 2c.
and fred/kokish method doesn't seem to fit in my schema here.
however i found "old Duboin-Bocchi scheme" from Poky, that could work out for me.
1D-2C:
a) GF without 5M
INV with 6C
c) INV with 4+D
d) BAL INV
Development:
1D-2C
2D: 11-15, any 2-suiter or 3-suiter
2♥: one-suiter or 12-14 balanced
2♠: clubs, 16+
2NT: hearts, 16+
3♣: 5D4♠, 16+
3D: 64♠, 15+
3♥: 6D5♠, 14+
3♠: 4450, 15-17
After the potentially weak rebids of 2D and 2♥:
1st step: GF relay
2NT: BAL INV
3C: 6C INV
3D: 4+D INV
===========
with above method, somehow i can stay in 2D/2N/3C partscore contract.
and 44 major fit after opener 2D/2H rebid would still need to be constructed.
