I played a version of Blue Club (modified for English tastes) for about 10 years. I have studied the books, and at the time thought that getting rid of the 13-17 1NT (in favour of a weak NT structure) and playing a more Precision-style 2c opener (with more elaborate relay structure) were improvements. After a hiatus of almost a decade, I was lucky to acquire a new partner who plays something very close to the original (but with a Precision-style 1c subsystem). From this perspective, I find that the system as originally conceived has more internal consistency than our homebrew "improved" system. The wide-range NT causes little trouble in practice, and the restriction on 2c to be upper range when it contains a 4-card major tightens things up. One thing I find most refreshing about Blue Club is the small amount of conventional baggage that it carries - in stark contrast to a playable 2/1, for example. It is fun to play, works very well on distributional hands, and if I had to play a system that wasn't "anti-field" I would probably give up the game :) --ian
