General Bidding Style

General Bidding Style

We open all 8+ HCP* hands in 1st and 2nd seat except:
1) Unfavorable: 8-11 without a 4CM or 5Cm, 8-10 5m4m/5m332
2) Other vulnerabilities: 8-9 hands without a 4CM or 5Cm

Our weak 2's (only in minors not unfavorable in 1st/2nd seats) are usually 5-card suits
Our 3-level preempts are generally 6 or 7 card suits

Strong 1D and intermediate and unbalanced 2H/2S (showing either 5431 with a 4 card minor or 6+ in the major, not MM, and 10-14 HCP)

Artificial 1C includes all patterns in the 10-14 range that are not opened with 2M.

Variable NT (mini in 1st/2nd NV: 10-12 Vul: 11+ to 13, 3rd/4th: 15-17 no 5CM)

Opening 1M 1st/2nd: NV: 8-10- Vul: 8-11. Any pattern with 4+ in that major (except that both majors are always opened 1H). If natural NT pattern, HCP less than the 1NT range or some downgrade. If unbal, more than 7 losers or some downgrade.

Opening 2m is weak except at unfavorable.

In 3rd seat, we will generally pass balanced 13's and some balanced 14's. 2 of a suit is wide ranging 5+suits including weak up to 14. 1 level is all str NV 1D 18+ and everything else 15-17, 1C F1. The only difference Vul is 1C is 13+-17.

In 4th seat 2 of a suit is 5+suit 13-14 and the 1 level same as 3rd.

*We routinely upgrade if we have 10+ cards in our two longest suits

Opening Leads AND Leads in the Middle of the Hand

Attitude shifts mid-hand

Defensive Signals

UDCA. Generally attitude unless known, then count unless known, then suit preference. We attempt to give count or SP earlier if we judge partner will need it.
