Defense vs Polish Club and "Short Club"

[Chamaco]

What do you think of a structure that replicates strong club opening with some modifications ?

 

--------------------------------------------

 

X = 16(17?) +, any shape except 2 suiters.

Advancer bids as if responding to a strong 1C opening.

 

1D = takeout limited (max hcp = 15) , guarantees 43 or better in major, can be void in diamonds.

Basically it's a nebulous 1D, but includes the 3-suiter short in Diamond.

 

1H/1S = natural, NF

 

1NT = Raptor (or some specific 2 suiter ? )

 

2C = natural, same as Precision 2C

 

2D/H/S = weak 2, natural

 

2NT = 55+, diamonds + major

 

3C = 55+, both majors

Might work B) But I like overcalling on 4-4's too much :)

Above 1♦ and not 1NT - as over a natural ♣ opening except jump overcalls are aggressive when not vulnerable.

 

Double: Passable Value Showing Double - 2+♣s, 13/14+. Next double by either this doubler or advancer is a Passable Takeout Double (i.e. like a negative double, and can be passed with length and values in suit doubled).

 

1♦: Natural or Takeout of ♣s with short ♣s (at most one) and 11-17. Non-forcing. 1♥ by advancer asks hand type, with 2♣ showing short ♣ hand.

 

1NT: Takeout of ♣s with 17/18+. Forcing.

I think that the strong-pass Lambda defence is popular against all strong ♣ systems.

 

It goes like this:

 

x - 5+♥ 8-15 (5332, 6322, 6331)

1♦ - 5+♠ 8-15 (5332, 6322, 6331)

1♥ - 5+4+ ♣♥ or ♠♦ 8-15

1♠ - 5+4+ ♣♠ or ♦♥ 8-15

1NT - 5+4+ ♣♦ or ♥♠ 8-15

2♣ - 5+ 8-15 (5332, 6322, 6331)

2♦ - 5+ 8-15 (5332, 6322, 6331)

2M - 6+ preemptive

2♣ - 5+ 8-15 (5332, 6322, 6331)

2♦ - 5+ 8-15 (5332, 6322, 6331)

2M - 6+ preemptive

This is the defence that Balicki/Zmudzinski were playing against a Polish Club (although I believe 1♦ was either just spades or balanced 4-4 majors). In all cases next suit up was relay.

 

Against a non-forcing Short Club (which is what I play), we just treat it as natural with 2♣ being Michaels. There is a case to play a 3♣ overcall as natural.

I treat short club as a reg. club opener.

 

Over the Polish:

 

X - majors or minors

1D/H - transfers into H/S

1S - reds or blacks

1NT - pointed or rounds

2X - natural

 

I treat direct jumps as intermediate in nature to allow pard to raise freely over 1C-2H/S-X.

Yes I think you're right. There are few versions of this defence, and they probbably used 1♦ 4-4 majors (with 54 1nt).

 

I've also heard about a convention against 1♣ called Warsaw diamond. 1♦ overcall is 8-12 (or 6-10 maybe?) on diamonds or 4-4 in majors. It's very nice because responder is affraid to bid 1 major, and they have no opp. suit to force.
