1D= 4+Hs

[WGF_Flame]

Hello,

I'm trying to build a new system, how would you continue over 1D which shows 4+h and 11-22 hcp ?

[rbforster]

How about 1♥ as GF relay and other bids approximately standard as if opener bid 1♥ promising 4+? I guess that makes 2m natural invites rather than 2/1 GFs, but otherwise it should work. Responding 1♠ or 1NT may just be looking to improve the contract (0+ pts if unwilling to pass 1♦), and could both be played as non forcing.

You might find it helpful to look up the Australian submarine opening system which has been played at BB level. From memory they use 1H as an INV+ relay but the full CC is available online if you look around. (Just an additional note, the system uses a strong club so the 1DHS openings are limited - however I believe the structure will be adaptable.)

Thanks I think i will try step as a relay inv+ and other bid as some kind of limit. I hope it will have significant enough advance over natural 1H opening (which is easier to pass) otherwise it doesn't worth it.

Are balanced hands included? Can you have a longer minor? Can you have longer ♠? Which 4441's are included?

longer minor-yes, bal- probably not (only if it will fit well enough),4441- probably only with singleton spade.

Oh, I forgot a very important one: do you have system restrictions about responses? :D

No :)

Playing MOSCITO I strongly prefer to play 2/1s as natural and non-forcing.

I don't think that this is playable given the wide range of your opening bid.

 

Personally, I'd lean towards using 1♥ as a GI+ relay and use a transfer response scheme

 

1N = Clubs

2C = Diamonds

2D = good raise to 2H

2H = preemptive raise to 2H

2S = fit showing (6 Spades and 3 Hearts)

2N = Limit raise+

3m = fit showing

3H = value raise

I'm a fan of the newer moscito structure and I think it may be workable with your opening even though it's large ranging.

 

Something like:

1♥ = general relay to let opener describe his hand (any balanced or any GF hand)

1♠ = natural, F1

1NT = ♣s, less than GF

2♣ = ♦, less than GF

2♦ = good raise, 3♥

2♥ = weak raise, 3+♥

2♠ = weak 6+♠ (or INV if you prefer that)

2NT = INV+ with 4+♥ fit

3m = INV, good 6+ card suit, 3♥

3♥ = mixed raise

3♠/4m = splinters

3NT open for discussion (you may use this as a splinter to show different ranges or difference between singleton/void).

1♦-3m is a bit strange, with invites you could also just transfer and rebid 3m. Therefore it makes sense to show the difference between 3 card support or not.

 

After 1♦-1♥ you can play something as follows (here the limited range has it's advantages to stay low):

1♠ = natural, 4♠ (perhaps even any strength and forcing, to create extra bidding space for strong hands)

...1NT = balanced

...2♣ = GF relay

...2NT = balanced INV

1NT = unbalanced, longer m (or 1=4=4=4, but I prefer to open these with something else)

...2♣ = P/C

...2♦ = GF relay

...2NT = balanced INV

2m = min, 5+♥, 4+m

...step = GF relay (not 2♥)

...2NT = balanced INV

2♥ = min, 6+♥

...2♠ GF relay

2♠ = extra's, natural (or longer m if you use 1♠ as any strength)

2NT = extra's, longer m

3m = extra's, 5+♥, 4+m

3♥ = extra's, 6+♥

 

This gives you full relays when opener is minimum, but might give you trouble when opener is max. You can't have it all... ;)

Thanks alot guys.

If your opening is unbal unlimited i would play something like

 

1D-1H (1H is 5+ relay)

??

 

1S= clubs

1Nt= Diamonds or 6H 15-17

2C = H+S min or GF

2D = 6H min or GF

2H = 5H+4S 15-17
