I've played a similar system in GCC events. 1♣ - 15+ Bal, 16+ Unbal 1♦ - 2+, 11-15, Unblanced, Canape 1♥ - 4+, 11-15, Canape 1♠ - 4+, 11-15, Canape 1NT - 11-14, Includes 5M322, 5M422 (optional, may be opened in the 4 card suit), 6m322... 2♣ - 4+, 11-15, Canape (yes, this is mandatory systemically on, say, 6=1=2=4) 2♦ - Mini-Roman (Don't snigger...nessesary to make the system work.) 2M - 10-13, 6M, no 4 card side suit 2N - Minors Notice how the 1x openings practically promise a side suit (and in fact we systemically open the side suit, not the 6 bagger....pretty strict canape) Never had any director complaints playing in mostly sectional-level events.
