General Bidding Style

Usually 5 card Majors (1N Resp F, (5)6-12), 4 card Majors likely opened in 3rd or 4th seat
Min Opening: 10-11 Unbal, 10 BAL NV, 11-12 BAL V
Variable NT: 10-13 1st/2nd NV, 14-16 1st/2nd V, Good 14-17 3rd/4th all and overcalls, 1N rebid changes to the other range depending on vulnerability.
All balanced hands in range are opened 1N including 5 card majors. Some semi-balanced hands as well, 5422 with 5 card majors,
6322 with 6 card minors with play in NT
Twisted SW1NE used after 1N-(Pen X)
2/1 GF, 3 under INV
1H-1S, 1M-1N: Forcing, Gazilli continuation
1 level overcalls 8+ HCP and may have 4 cards. Usually 4 card overcalls are over unpassed hand when overcaller has a hand that would be opened 1m and can't overcall 1N or it is a weaker lead-directing bid that is okay with playing at the 2 lvl.
2 level overcalls are generally sounder, but no guaranteed strength
1C with 3-3 minors, 1D with 4-4 minors
Weak 2 Preempts: Wide, usually light
3rd Seat Preempts: Range from wk to int. Int is a 6 card suit that would deny an invite to game
4th Seat 2 Level Opener: Strictly intermediate with a 6 card suit.
3 Lvl minors: Could be 6, must be broken suit
3 Lvl majors: Guaranteed broken suit, a hand that can't bid NAMYATS
3N: Gambling single suited minor
4m/4M: NAMYATS
Vs an artificially strong opening, an overcall at favourable vulnerability, if not conventional, shows a long suit and is usually lead directing if partner is unable to sac.

Opening Leads AND Leads in the Middle of the Hand

vs ALL: Polish 2nd/4th, small from doubleton, 2nd from bad, 4th from good, may lead BOSTON from 3 if spots are not clear enough and count is less important.
vs NT: Rusinow, A asks attitude for Q, K is power for any Q or J unblock or count, Q asks for J unblock or attitude for A or K, J is highest, T is 1+ touching and A or K, 9 from T9
vs Suits: A from AK+ (except 5+level)
Hx Leads: Small if not partner's suit, H if partner's suit. Usually small from Tx or Jx unless partner rates for values
Middle of Hand: 2nd/4th leads upside down remaining count
May occasionally lead incorrect honor or spot

Defensive Signals

Upside Down Count & Attitude
First Discard: Lavinthal
Signalling Priority Normally: Attitude, Count, Suit Preference (Count may be inferred from attitude signal, meaning we will try to play correct count if able while giving correct attitude). Suit preference is given if 3rd hand is known to be unable to cover card in dummy or with singleton in dummy and in any situation where the suit is obviously not useful.
vs NT: Count is given on first trick if dummy wins trick 1. Reverse Smith played at first trick led by declarer.
vs Suits: Obvious shift attitude is given at trick 1 for the remaining 2 suits that are not trump. Unusual honour calls for unusual shift
