Bids that Require Advance Preparation

1m - 2♥ : balanced invitation
1m - 2â™  : mixed raise
3NT : (56)+ minors in 1st or 2nd seat (3-9 hcp nv, 6-10 hcp vul); gambling 3rd or 4th seat

General Bidding Style

Openings
Occasionally pass balanced 12 counts, moreso vulnerable
Open many unbalanced 10 and 11 counts
3rd seat, regularly open light with a good suit
3rd/4th seat, may rarely have a 4-card major if willing to pass any natural response
33 minors open 1c; 44 minors, open 1d; 45 minors, always 1c
With 56 hands, nearly always open the 6-card suit
1NT: 15–17, occasional upgrades, rare downgrades; may regularly have 5M or 6m; (5422) hands sometimes 1nt (especially if rebid problems); rarely singleton honour
2NT: 20–21, same as 1NT in terms of shape


Preempts
Rarely 5-card suit, usually only if nv and 3rd seat
1/2 seat weak two will very rarely have a side 4-card major, may have a long minor
3-level preempts are usually 7-card suits when red, may be 6-cards if white
Generally expect decent suit quality, but not much particular strength


Responses
Regularly respond very light (0+ hcp). nearly always with: a 5-card major, a stiff or void in partner’s suit, an ace
1c - 1d only has a 4-card major if inv+ with 5+ diamonds
In 2/1 auctions, rebidding major shows 6, a new suit at the 3-level doesn’t show extras


Doubles/Redoubles
Doubles are takeout/values unless defined as penalty
Redoubles are sos at 1 or 2-level, or at the 3-level in balancing seat; otherwise penalty
Passes of redoubles are penalty at the 3-level and higher, otherwise takeout


Competition
2/1 in competition may not have full 10 hcp, many follow-ups are nf
1M - (x) - 3♣ mixed raise
Jump raises always mixed unless another mixed raise is available


Psychics    (。Θ ω Θ。)
Rarely, very light lead-directing bids in 3rd seat, especially if nv
