Here's a snapshot design of a 4 card major with Big Or Weak D Club

1C: 17+ any or 11-13 Ds & no four card major
-- 1D: 0-7 Negative - now 11-13 Ds passes, rest shows 17+
-- 2D: 8-11 Balanced, now 11-13 Ds passes, rest shows 17+
-- Over 1M positive, 2D is 11-13 Ds with no fit, raise is 11-13 Ds with fit
-- Over 1M positive, 1NT 17+ and balanced or Ds or fit, 2C asks which
-- 1NT positive is 12+ balanced or 8+ with Cs.
-- Over 1NT 2C is 11-13 Ds, 2NT 11-13 5+Ds & 4Cs, 2D 17+ asking, rest 17+ natural
-- 2C positive shows Ds, 8+. Now 3D is 11-13 with Ds, and 2D 17+ asks.
1D: 14-16 balanced/semi-balanced or with Ds
1H/S: 4 or longer major, 10-16, not balanced if 4M, not hand for 2H/S opening
1NT: 11/12-13 balanced (reason for tight range is to have less invite sequences)
2C: 5+Cs, no 4cM, 10-16
2D: Multi
2H/S: 5+ in major 9-12, not 4 in other major
2NT: 11-13 5-5+ in minors
