i want your oppinion about this system:
1C = polish club style but including 2C hands (19+ any or 11-14 balanced or 11-18 with clubs)
1d/h/s = natural 11-18
1NT=15-17
2x = misc preempts

after 1C, answer and developments are very polish club like (1C - 1x - 2D relay etc), except 1C - 1M - 2C shows clubs with 11-17 (i guess...).

apparently, the system is playable: http://www.ecatsbridge.com/documents/files...rek-smirnov.pdf

Not as good as Polish Club - the whole point is that the 1♣ opening should "show" a weak no-trump.

It does, because the 1 NT OPENING is 15-17, as stated from vang.

I am not sure why they changed it. I had belived that 1 Club 1 any 2 club as 11-17 creates more problems then it solves, but surely the two know what they are doing and they do it very successful.

It's not quite as bad as opening a precision 2♣ with such a wide range (11-17), since at least responder has had a chance to show a 4cM. Their 1♣-1♦ shows 0-6 or 7-10 unbalanced minor(s), so maybe the continuations aren't too bad. If you're on the low end, you pass 2♣ and still don't miss anything game-wise (if not fit-wise). Otherwise, maybe you can raise to 3♣ or bid a natural(?) 2♦ with a constructive hand.

I kind of like it : the 1♦ opening can be stronger than in the original polish and that address one of the major flaws of the system according to my experience : showing Diamonds after a 1♣ can be difficult.
They probably (hopefully) have good agreements in place after interference over their 1♣ opening : the default hand is no longer a weak no trump as unbalanced weak club opening are frequent too (easy to loose club fit if you always assume weat no trump type)

The problem that comes up is, say you have some fairly simple competitive auction like:

1♣ - (1♠)

Partner is supposed to bid on most shapely hands which would make game opposite a (minimum) strong option. So partner needs to find a call with something like 7 hcp and a diamond suit. If partner passes this hand, the opposing spade raise can really bury opener's strong hand.

This is a problem (to some degree) with Polish Club in general; Strong Club actually does much better than Polish given a similar degree of competition.

Polish Club players deal with this by playing negative free bids. This strategy works because a weak notrump is always prepared to pass the negative free bid -- basically these bids say "this is where I want to play if you have a weak NT, but I have enough for game opposite the big hand."

The issue with adding in large numbers of other non-strong hands (i.e. club one-suiters) is that they are not necessarily well-equipped to pass the negative free bid. For example, say you see:

1♣ - (1♠) - 2♦ (NF)

You hold a 3307 hand. Do you want to pass? Keep in mind partner could have a five-bagger. My suspicion is that you don't want to pass. But now bidding 3♣ has a very wide range (could be minimum that hates diamonds, could be extras but not the "big hand" of 19+ hcp, etc).

Of course, you may consider that this is worth it, but the primary gain from this method is going to be that you free up your 2♣ opening for a preempt. So you have to be getting pretty good results from whatever preempt that is to compensate for the occasional competitive losses when you open 1♣ on an unbalanced hand.

Well, if I was going to open up the 1C even more by bringing in the 6+clubs hands, I would go Nasz, and make 2C strong, artificial and (almost) game-forcing - the "other" Polish Club. I think that limiting the catchall strong part of 1C to 21, 22 or so would show larger gains than whatever preempt you put into 2C.

OTOH, I could very easily be speaking out of my hat, because my non-Precision strong club experience is with a Swedish-style system (16+ or 11-14 bal), not a Polish-style.
