Actually my partner and I have played this for over 20 years (at least some version of it - it was constantly evolving for a while), with quite a bit of success. As to the problem of preemption over 1♣ ; for over calls thru 2♥ we use, basically, Fishbein for takeout and double for penalty. It's amazing how large the numbers can get when people are trying to screw us up. We have not played this in any national events, but have had success in regionals. Oddly enough our non club suit opening bids come up fairly often. We find that we can bid distributional slams very easily with this. We play mostly in the Pacific NW (USA) and have had a lot of success playing against some of the better players here. While neither my partner nor myself are at the top level of bridge (he has over 5000 MP's and I have about 2500 - I don't play much), we do advise that this system is 1) not for the faint of heart and 2) best kept to better players. For those of you who don't think much of it, well, when Pete and I first started playing it we didn't either. It really started out as a joke, but, much to our surprise, it seemed to work quite well so we started actually working on it, expanding from 3 handwritten pages to over 100 typewritten (w/ hand diagrams - probably only 40 or so pages without). One thing about this system; like most complex systems it allows no deviation, so when we bid we have what we say we do. Plus, it's a lot of fun to play; most of the time a find bridge pretty boring these days.
