General Bidding Style

Precision (RM medium style;). Open lighter NV as a rule.  Preempts normal to slightly aggressive. 1NT= 14-16, but 15-17 in 4th seat, or 3rd seat VUL. 2NT= 19-20, 20-21 in 4th seat, or 3rd seat VUL. 1= 16+,  1= 2+'s 11-15 catchall bid,  1/= 5+ 11-15,  2= 6+ 11-15 (could have a 5 card major),  2= 3-suiter short in (can be 43 in Majors either way) 11-15.  3rd seat can be very light especially NV and might be on shorter length (e.g. 4-card Major). Preempts can be on 5 (weak 2's) or 6 (3's). General light style, and variations allowed, e.g. can open 1NT with 13 if we think it is worth 14, or 1 with stiff K of instead of 2, or opening with less than 11 HCP with a reason to to so.Â
