What club-specific bidding rules are allowed in EBU clubs?
This topic came up at a club committee meeting and I wondered what clubs are allowed to do in terms of club-specific rules. The Blue book defines levels of partnership understandings so it is obviously OK to stipulate that club events are played at level 2 or level 4. Is it also allowable to have special rules? For example:
- To disallow strong no trump openings?
- To disallow psyches?
- To disallow multi 2D openings (other than by playing at level 2)?
Note I don't personally favour special rules like this but realised that I am not clear about what is acceptable in EBU clubs.
