I've been playing Blue Club for many years and with advice from a top aussie player have made some modifications. 2pts off everything. That means 1C is opened with 15pts and 1D, 1H, 1S and 2C being 10-14pts. We've dumped the 2D 4,4,4,1 bid for a weak 2 and 2NT now is for both minors and 3C is now pre-emptive. 2H and 2S are the same as is 1NT although the strong NT is now 15-17pts. The changes were recommended on the basis that there is not much point in having bids that only are rarely bid. Now 1C is opened regularly which gladdens my heart. The strengths of Blue Club are many. Essentially it is a very natural system with only a few conventions and is good for finding slams. Canape means that if you play a part score it is in your better suit, usually at the 2 level. We discovered that opening with 10pts on rubbish can be a mistake, so 10-11pts are discretionary, 12+ mandatory. We still use control responses to 1C although I'm interested in checking out alternatives. Even though the 1C responses have some issues, compared to the responses used by Standard to 2C they are a million times better and the majority of people we play against play Standard.
