Is anyone aware of a strong club system in which 1 of a major may be opened on 3, 4, or 6+ of the opened major suit? The observed system uses 2d opener to show a 5 card major. 1nt openers are 8-11 Not Vully, 14-16 Vully, but Not Vully 7 hcp are often opened 1NT. There is a pair playing on BBO using this system with totally remarkable success at IMP.
