General Bidding Style
| Light opening: Open all balanced 11 when we are not vulnerable, optional when we are vulnerable. Open shapely 10 (9 not vulnerable).
1 = 2+, can have long if balanced
1 = unbalanced, 5+ or 4441
1N = 14-16 1st, 2nd and 3rd NV, 15-17 3rd V, 4th could be shaded in 1st and 3rd seat when we are not vulnerable (13 with a 6-card minor). Often 5-card preempt at favorable vulnerability especially in 1st seat. 2M is 6+M, 10-13 Respond very light when we are not vulnerable. |
Opening Leads AND Leads in the Middle of the Hand
| 3/5 vs suit, 2/4, Rusinow from 4+ except in partner's suit, dummy's suit, and preemptor's side suit, Reverse Smith vs NT.
Mostly attitude in the middle of hand. A from AK except from AK doubleton, ready to switch to a side singleton, or at the 5-level or higher (ask for count). Standard suit preference and present count. Suit preference when dummy has a singleton. |
Defensive Signals
| UDCA.
Attitude when we lead, count when declarer leads. Count is usually accurate early in the hand, suspect later in the hand. Suit preference when the attitude/count is clear. Reverse Smith except in a hold-up situation when dummy has a long suit with no clear side entry (A or K). Sometimes would lead small from doubleton for deceptive purpose especially when we can overruff dummy. |
