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).

1C = 2+, can have long D if balanced
1D = unbalanced, 5+D 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.
