General Bidding Style

Precision
1C strong = 16+ HCP
1D = 2+D, 10-15 HCP
2C = 6+C, 10-15 HCP
5-card Majors, 2/1 GF
1NT = 14 to 16 (Except 15 to 17 in 3rd vul, or 4th)
Balanced 10 or 11 point hands may be opened 1D or 1M
May respond to 1D or 1M with a very weak hand
1M (P) 2C could be a doubleton
1st seat NV vs V preempt can be light
When partner opens or overcalls 1M or 2M, and the next hand doubles (takeout, negative, support), we play transfers beginning with NT
Weak 2-Bids usually 6 card suits

Opening Leads AND Leads in the Middle of the Hand

vs NT: Rusinow (from 4-card or longer suit) down to the 9-8 (8 from 98 or 87)
vs NT: 4th best leads. Might lead 1st or 2nd from bad holding. Usually do not lead 2nd from 2 equal spots lower than the 9.
vs NT: 3rd/5th in partner's suit
vs NT: Middle of hand: lead original 4th best usually
vs Suit: 4th best usually. 3rd/low in a raised suit. May lead high from 3+ small in a raised suit or if partner can infer length.
vs Suit: A from AKx usually. K from AKx if 5-level or higher, 3-level preemptor declaring, or suit partner has bid the suit.

Defensive Signals

Standard count, attitude, and suit preference
Primary signal: Attitude
Occasional suit preference in trumps

Smith Echo vs NT (high encourages opening lead suit), except if obvious count situation
