1♣ is strong (usually 14+ in the first 2 seats, 17+ in 3rd and 4th)

1nt is weak in the first two seats 10-13; 3rd and 4th seats 14-16

all the bids from 1♦ to 4♦ (except for 1♥, 1nt, 2♥ and 3♥) are 2-under, showing the n+2 suit, unbalanced hands and denying unbid 4+ card major(s); intermediate range (8-13 usually in the first 2 seats) - in 3rd and 4th seats the HCP range can vary from 0 to 16

a double by responder is not negative, but proposing a penalty

a reopening double shows a singleton in the opponents’ suit (so a penalty pass is also allowed, in addition to the penalty proposing double)

handy conventions that fit nicely: rubens, various forms of lebensohl, fit jumps; we don’t play SWITCH in this system

signals: UDCA; discarding: UDCA; priorities always: Count/Attitude/Suit Preference; we give Count often

leads: always 2/4; top of sequence; J from KJT

1♣ = 14+ (17+)

1♦ = 4♠ exactly

1♥ = 4♥ exactly

1♥ - 2♥ = 4♥, weak

1♥ - 2nt = 4♥, inv+

minor rebids show 5+ cards in the minor

1♥ - 1♠ = 5+ cards, forcing 1 round

1♥ - 1nt = relay, forcing

1♥ - 2♣, 2♦ = nat, non-forcing

4+ ♣s, usually 54 in the minors

2♣ = 5♥, 8-13 hcp, unbalanced

2♦, 2♠, 2nt, 3♣, 3♦, 3♠, 3nt, 4♣, 4♦ openings have a similar structure

2♥ = 4-4 / 5-4 majors, 8-13 hcp

3♥ = 5-5 / 6-5 majors, 8-13 hcp

pass = to play

xx = relay

2nt = inv+, fit

fit jumps

new suit non-forcing

XX = inv+, 12+ hcp, establishes an unlimited forcing pass sequence; subsequent doubles are for penalty

new suit = non-forcing, 5 cards, partner can raise with 4 cards

pass = non-forcing, denies a 5 card suit; subsequent doubles are for take-out

1nt - [X] - pass - [pass] -
