Say you play a 1♣ opening showing:
- normal opening with ♣s (minimum length depending on the rest of the system), say 3+♣s
- 18+ HCP any shape

How do you deal with natural intervention?? Examples: 1X, 2C (55+M or whatever), 2X weak, 3X preemptive,... How does partner bid, how do you show the 18+ version, how the normal version?

[the hog]

Any bid by opener shows the stronger C version. As the 1C opening can have a 5+ card M, bids of a M at the minimum level show a min strong hand with 5+ cards, NT bids are natural, and X is for takeout.

Continuations over this are normal - pd raises or cues with support, depending on strength, or bids NT at the appropriate level. Over a t/o X at the 2 level, Leb applies - or if you want to get fancy, Rubenshol.

After a 2C or 2D 2 suited overcall, the first 2 Xs are for takeout and the third is for penalties.

This is what we play and it seems to work.

And how does responder bid? As it was a normal 1♣ opening or do you use some other scheme after that?

That depends on the level of intervention, Free. If it is at the 2 level, then as I stated Leb is used to show weak/better hands.

Here is a summary:
After 1C (X)
P=0-6
1D = 7-11 H
1H = 7-11 S
1S = 6-9 C
1N = 7-9 no M
2C = GF short C!!
2? Weak

1C (2D) Wilkosz
2N N/f with a m OR GF with some M
3m forcing
X 9+ pts

1C (2H)
2N Leb - various weak or strong options
3C/D forcing
X 9-11, or GF if opener bids again

Similar over a 2S overcall, except that X = invit with 5H or GF with 4H.

If you can translate Polish, I can send you the complete structure.

Bridgebase polish site has polish club summary and large polish club system write up in english.

Dan Neill has a version in his systems page: WJ2000

[the hog]

A couple of points:
Dan has essentially 2 Polish Club, (PC),variants on his web site. (There are a couple of exotic others, such as relay based PC.

WJ2000 is Jassem's write up of the way most play PC. This is not what the top Poles play - cf SAYC with 2/1. This is also the write up on the Polish BBO site.

The second system is a summary of Strefa which is what Marek Wojcicki plays and also Kwiecken. This has a 2C GF opening unlike PC which has a 12+ club and a Precision style 2C.

Neither of these have detailed structures over intervention. Marek's notes do have this detail, but as I stated, they are in Polish. With a bit of nous, however, you can work out the meaning.

I got a question then for the WJ folks - why is it after intervention of their 1♣ opening the only bids they know are pass and double? Is this systemic? Realize for the record my pard and I treat ALL 1♣ openings as strong, and use our Nightmare defense against it. Normally we get good boards.

That is not my experience -the only bids they know are pass and double? - Pass is certainly not uncommon, as most of the time the 1C opener will have a weak NT type of hand. For this reason it is systemically poor to treat the 1C opening as a strong bid. An interesting defence is to use the structure you use over the opp's 1N opening.
