2 level responses to an unbalanced 1D Building on Mgoetze's work
#1
Posted 2014-November-11, 20:01
1D - ??:
1H: 4+ Natural, Transfer Responses
1S: 4+ Natural, Transfer Responses
1NT: Hands that cannot make a sensible other response (tends to have some club length, relatively weak)
Then the responses I'm not sure about. I really liked Mgoetze's 2C response, but I'm not sure how to make continuations work
2C: Clubs GF, Bal GF or 7-10 (maybe this needs to be 7-9) diamonds.
2D: Weak with a major
2H: Reverse Flannery by Responder - is this really required with Xfer responses?
2S: Initvitational+ raise of diamonds
2NT: Balanced invite to 3NT with short diamonds and no 4 card major
3C: Invitational with 6 clubs
3D: Premeptive raise.
Thoughts?

How do the transfer responses work?
Here's what I came up with over a similar 1♦ opening (albeit weaker):
1M: Natural
1N: < 12; not suitable for any other bid
1D - 2C (12+; GF unless suit rebid):
=========================
2D: 5+ diamonds, single suited min or two-suited hands
2H: Three suited, short clubs, min
2S: Good raise with 4+ clubs; 2N asks for shortness
2N: GF, 6+ diamonds
3C: Min raise with 4+ clubs
3N: Three suited, short clubs, max
1D - 2D (12+; GF unless suit rebid):
========================
2H: Three suited, short diamonds, min (rarely (42)=2=5)
2S: Good raise with 4+ diamonds; 2N asks for shortness
2N: GF, 6+ clubs
3C: Min, 6+ clubs
3D: Min raise
3N: Three suited, short clubs, max
1D - 2H:Reverse flannery, < invite
1D - 2S:Reverse flannery, invite
1D - 2N: Invitational

as my 1D promises 4+ Diamonds (and 4 only if any 4441 or (13)=4=5) I don;'t really need the short diamonds rebids by opener!
What I'm stumped on is what to do over 1D-2C - 2D effectively becomes P/C, but I'm worried that the separation between the hands isn't large enough.

1M - Natural with 4 cards
1NT - INV+ with clubs or bal(Think 1M-2C but instead of GF, it is INV+)
2X - Natural and non-forcing
2NT - INV + with diamonds
3C - Nat, NF
3D - Weak raise
3M - splinter

So both 2C & 3C are nat NF? What's the difference between the two?

We use the following:
1NT = Clubs, weak or GF
2♣ = Diamond raise, weak or GF (3+ if weak, 4+ if GF)
2♦ = 3+ diamond raise, INV
This is in combination with 1♥ being natural or a GF relay.
We use weak jump shifts, but you could probably find better uses for it. Perhaps:
2♥ = Balanced GF (if not wanting to use 1♥ as artificial)
2♠ = GF with a 5-5 pattern (not including diamonds)
In your original structure you could skip Reverse Flannery and play 2♥ as 4+ support and INV+, instead of 2♠, to save some bidding space.

Yeah, that's the plan. Sort of - A big question is how forcing is 1D-2C-2D - I think it can be one of the following 3:
1) Not Forcing
2) Semi Forcing (any 7-10 diamond raise that would reject an invite passes, anything else bids)
3) Forcing - absolutely forcing.
This effects your response structure considerably. Playing NF, my 'was bored in a meeting so sketched out response structure' was:
1D-2C (Big question - does this deny a 4 card major?)
A couple of holes there obviously.That's not great, but the rebids are cramped as well, and some of them are under or overloaded. That gives a response structure of:
Then 1D-2C-2D:
I'm not sure what to do with 3H+ - I think 3M needs to be quite a specific hand, and no idea what 3NT is? DNE?
I thought about Semi forcing as well. This makes all the responses easier because it's GF opposite the minimum, but sometimes it's not very clear what is going on in the rebids

NOT A BIG FAN OF THIS. 7-9 WITH DIAMONDS CAN BID 1N OR BIG DIST 2D. PREFER 2C INV+ CAN STOP IN 3C/D AND USE 3C PREEMPTIVE
2D: Weak with a major
THIS WHILE NICE PUSHES THE DIAMOND RAISE TO 2S WHICH WILL MAKE DIAMOND RAISE MORE DIFFICULT TO EXPLORE
2H: Reverse Flannery by Responder - is this really required with Xfer responses?
2S: Initvitational+ raise of diamonds
2NT: Balanced invite to 3NT with short diamonds and no 4 card major
3C: Invitational with 6 clubs
3D: Premeptive raise.
Thoughts?

1D-2S:
While this is clearly sub optimal contextually, its got the advantage of being easy to remember.
That said I think Kungsteen is right - I should scrap reverse flannery and pull the balanced game forces out of 2C.
This greatly simplifies responders rebid:
So after the 1D opener:
