Note: All of this is within a structure that is basically Precision. Nearly all hands of 16+ HCP are opened 1C. After positive responses there are many asking bids. Suit openings are limited. 1D opening is nebulous but natural in principle. Related systems are Match Point Precision and Meckstroth-Rodwell Precision. This system falls between the latter two in complexity. I don't have notes on the full system. What follows is an outline of responses to 1C with some detail of auctions starting with 1C-1D.

1C = 16+ HCP, but 2NT is 22-23 and 4C and 4D are Namyats.

1C-1D = 0-7 HCP, any distribution, but A+K (K not singleton) is enough for a positive and 8 HCP with no controls (i.e., all Q's & J's) is a negative. The bids 2S through 4C are used for 4441 positives, so 1D is *always* negative.

1C-1M = 8+ HCP (may be lowered with compensating distribution), 5+ suit.

1C-1N = 8-13 balanced, may include weak 5-card minor.

1C-2m = 8+ HCP, 5+ suit.

1C-2H = 14+ HCP, balanced, no 5-card suit. Now 2S is SAB in hearts,

2N is SAB in spades, 3C is Stayman, 3D is SAB in diamonds (!),

2M is 4 of M and 5+ diamonds, 3NT is SAB in clubs, 4m is (5-4)+ in minors, 4D being longer diamonds. Responses to these cramped SAB bids are: 1st step = 2-card fit, 2nd = 3, 3rd = 4.

1C-2S = 4-4-4-1, 8+ HCP, opener bids next step to ask size.

1C-2N = 4-4-1-4, as above. Step responses presumably as below.

1C-3C = 4-1-4-4, as above.

1C-3D = 1-4-4-4, 8 to bad 10 HCP

1C-3H = 1-4-4-4, good 10 to bad 12 HCP

1C-3S = 1-4-4-4, good 12 to 13 HCP

1C-3N = 1-4-4-4, 14-15 HCP

1C-4C = 1-4-4-4, 16+ HCP

1C-1D; 1M: With an unbalanced hand, opener must start the search for a major suit fit right away. Therefore, with AQxx x AKJxx Kxx, rebid 1S over 1D. Failure to bid spades now may lose the suit for good. This principle is applied to an extreme: to rebid 2C, 2D, 3C, or 3D over 1D denies a 4-card major. Opener can rebid 1H or 1S with a hand of any strength since the bid is a 1-round force. Exception: GF canape' bids 2H.

Any non-raise denies 4 trump. Failure to raise or bid 1S denies 4 spades.

1C-1D;

1H-1S = 4+ spades, forcing.

1N = 0-5, any shape.

2C = 6-7, at most 2-card support.

2D = 5+ to 7, artificial, 3-card support.

2H = 0-5 dummy points, 4 trump (can be Qxx w/ruffing val & useful hand).

3H = 5+ to 7- dummy points, invitational, no short suit, 4+ trump.

2S = 5-7 HCP w/5+ spades and exactly 3 hearts.

3m = 1st-tier splinter: lim raise or better, short in bid suit, 4+ trump.

4m = 2nd-tier splinter: slam try short in bid suit, 5+ trump, useful cards.

2N = 1st-tier splinter in unbid major *or* balanced GF w/4+ trump.

3N = 2nd-tier splinter in unbid major.

The system after 1C-1D; 1S is identical, but 2H shows 6-7 with hearts.

1C-1D; 1N = 16-19 HCP balanced.

1C-1D; 2m = Denies a 4-card major, shows unbalanced hand. 5 only with 5-4 in the minors. Responder's bids are natural and imply 5-7 HCP (perhaps a little less with a fit).

1C-1D; 3m = Essentially the same as 2C-2D; 3m in standard. Deny 4-card major. 4m is a possible contract, otherwise game.

1C-1D; 2N = 20-21 HCP balanced. Note that 22-23 HCP balanced is opened 2N.

1C-1D; 2H = One of 3 hands: (1) 24+ balanced; (2) 5-5 or better in majors, invitational; (3) GF Mm canape'. Responder is forced to bid 2S, and now:

1C-1D;

2H-2S; 2N = 24-26 or 29+ balanced.

3N = 27-28 balanced.

3H = 5-5 M's, invitational. (4m = cue for corresponding major.)

3C = GF canape', clubs. 3D asks for major.

3D = GF HD canape'. (4+ hearts, 5+ diamonds, longer diamonds.)

3S = GF SD canape'. (4+ spades, 5+ diamonds, longer diamonds.)

1C-1D; 2S = 3-suiter, 19+ HCP, forces 2NT. Opener then bids short suit.

Bidding is all natural thereafter.

1C-1D; 3M = Minor 2-suiter, short in M, GF.
