responding to prec Nebulous 1d after dbl

[Chamaco]

Assume you play precision with nebulous 1 diamond including:

-13-15 (semi)balanced

-4441 (no diam sortness)

- any 54-55-45 in minors

- unbalanced with diamonds (5clubs+ 4M are opened 2♣)

 

what are your set of responses after opp double ?

E.g after

1♦-(Dbl)- ?

 

1) new suit at 1 level forcing or non forcing ?

2) new suit at 2 level = forcing or non forcing ?

3) any suggested meaning of jump bids (I usually use them as preemptive)

4) what is the suggested meaning of 1NT ?

5) Redoiuble is 10+ balanced or what ?

6) do you use conventional bids for good unbalanced hands in the minors (not suitable for redouble) ?

 

Finally, is there a thorough description available somewhere of what Meckwell use in this situation, besides their convention card ? Or do you have any info ?

 

thanks !! ;)

Pass, 4th hand bids something, opener will almost always pass unless he

has extreme distribution, pass, then start doubling.

 

Second answer:

 

Here's the Mechwell methods I've come across (certainly their

methods aren't tuned to penalize opponent's 1 level suit bid unless

they choose to Pass, awaiting a reopening Double):

 

1D-(X or overcall)

-XX H:4+card

-1H S:4+card

-1S 8+,balanced

-1N Clubs

-2C Invitational

-2D Round (H+C)

-2H 4=5 in majors, invitional

-2S 5=4 in majors, invitational

-3C Minors, mildly invitational

-3H/S Major length, game force

 

1H/S-(X or overcall)

-1N 6-10, Clubs

-2C 6-10, Diamonds

-2D 6-10, Hearts

-2N Limit raise

-3C Raise, Round (C + H)

-3D 7-9, 4+ Heart support

-3H/S Preemptive

-4C Splinter in opponents suit

 

1N-(X) if 1N is 9-12 or 13-16

-XX Round (C + H) or Pointed (D + S)

-P Round (C + H)

-(P)-XX No 5 card suit

-(Suit) 5+ card suit, natural

-Suit 5+ card suit (natural)

 

1N-(X) if 1N is 14-17

-XX 8+, Systems On

 

1N-(overcall)

-X Negative through 3S (Lebensohl)

-4D/H Transfer

Transfer advances after a Dbl seems the best imo. Gives you a lot more options to show your hands and find a nice contract.

Thanks Matthias ! :D

 

The scheme sounds interesting, so I have tried making my own serch on the internet on which are the sequences after the responses, but I had no luck.

There seems not to be much material on the questions that i list below.

After the transfer response, what is the policy of opener ?

 

1) should he ALWAYS accept the xfer ? In this case, if responder rebids, is he invitational even when making a weakish 2nd bid such as:

• own suit rebid
  
• raise pard suit
  
• bid cheapest NT
  

How should one differentiate a 2nd round bid

a ) weak (especially if u are weak and have xferred into a 4 card suit)

b ) invitational (whether or not u xferred in a 5 bagger)

c ) GF (same: xfer in 4 or 5 bagger)

 

2) if opener does not have the obligation to accept the xfer, what does it mean if he(being limited to max 15) does not accept the xfer ?

 

 

Thanks all !! :)
