After

1D 1H 1S showing D+C

 

responder will bid 1NT...

 

CASE 1 almost all GF hands (you will bid 2S GF relay afterward)

 

CASE 2 all INV hands (you will bid the inv suit at the cheapest denomination)

 

CASE 3 weak hands with 33,44,22,23 in the minors you will pass partner 2m/2H responses

(if partner got 4H/5C you will play 2H/2C otherwise you will play 2D UNLESS hes {18-22}

 

Where responder should not bid 1NT

When he knows wich partscore is best. 6-9 pts

(because of the J of S 6NT by south is good too)

[zenko]

so how do you respond on 1D with say 6-8 points , 5 clubs, 2 diamonds and 3-3 majors?

[benlessard]

1H when weak show at least 3 cards. partner will repeat his D or show a 2 suiter and you will play 2D in 5-2 fit or play in 2H in 4-3 fit if opener has 4H.

 

The worse hand is a weak 3235, but you can bid 1Nt (club transfer) followed by 2D (show 6C+3D weak ) or you can raise immediatly (2C or 2D)

 

Its obvious to me that if you believe in relay bidding, 1H should be a relay, its the continuation that are not obvious. Its also obvious to me that you want most of opener rebid to be forcing so that he can show a 2nd suit and make a final shape bid not too high at the 3 level instead of making a stupid jump shift at the 3 level, after several setup i became convinced that 1D---1H----1S should show clubs because it allow you to open 1D with 4D and 5C and to deal better with 4441,4144,1444 it also allow you to inv and often stop at 2D wich is often way better than 2Nt, + it allow you to play better partscore when 22 or 33 or 23 in the minors.

 

The cost of all this is that you cant stop in 1Nt anymore (but its still better than reg 1Nt forcing since opener cannot be 5332), opener cannot make direct 3 card H raise and that if the 1D opener is the dealer than lho might preempt after your 1H response.

 

Its not great for MP since you often play in 2m instead of 1Nt or 2M but for slam no other setup come close imo.

 

The type of slams that we are missing are the stiff K facing aqJ and when responder has the side suit AKxxxx or AQxxxx in a weakish hand where opener Hx and solid trumps become gold.

[zenko]

seem like a good structure, but for us playing in ACBL land unfortunately it is out of bounds, since ambiguous 1H answer on 1D opening is "superchart" convention and disallowed except on Spingolds and such events.

 

Interestingly enough ambiguous 1D response on non-strong 1C opening is allowed, as well as ambiguous 1S response on 1H opening, but 1H response on 1D opening has to show hearts (or at least a suit, not sure about that)

[PrecisionL]

Actually, 1♠ response to 1♥ opening has to be natural in ACBL GCC events. However, a 1♥ response to a general purpose 1♦ can occasionally be a 3-cd suit. In fact we play it that way if weak, otherwise 4+♥s even if longer ♠s.

 

The Kaplan Inversion (1♠ response with 0-3♠s) is ACBL Mid-chart.

[zenko]

Sorry I did not clarify, I was talking about mid-chart events which are widespread enough to make it worth a trouble (in my neck of woods even the unit game is mid-chart). While on that subject somebody told me recently that Kaplan inversion is now actually GCC, in which case 1H-1S can be played as 0+ spades in almost all events

BTW I have hard time finding on GCC where exactly says that 1d-1h(3+hearts) is allowed, it does not really fit in any of 10 itemized examples and it says on the top:

Unless specifically allowed, methods are disallowed. Is there any other document pertaining to that which if needed I can show to a director?
