1NT 13+-16, 10-13 (1-2 NV) avoid 5-card major, can be 2245 with 5m

2♣ 11-15, 6+ ♣, could be 5♣ in 3rd seat
2♦ 11-15, short ♦, weak two in 3rd seat
2♥/♠ Weak two
2NT 21-22

3♣ /♦/♥/♠ Normal pre-empts, rule of 2/3/4

3rd/4th seat: Gambling; partner should not remove.

4♣ /♦ 1st/2nd/4th seat: NAMYATS – 8 to 8.5 tricks in major (9-9.5 in 4th)
3rd seat: Natural and preemptive

4♥/♠ Natural, NAMYATS in 1st/2nd seat (< 8 tricks)
4NT Good 5 of a minor opening (ex Ax x x KQJ10xxxxx = 9 tricks)
5♣ /♦ Pre-emptive five-level minor suit opening

Support Doubles and Redoubles

Through and including 3 of our major.

If they bid 2 of our major:
Double = penalty if natural
Double = 3+ card support if Q-bid

After a support double, responder’s actions (except Q-bid) are never forcing … a new
suit is an attempt to play there.

Support doubles are not on when responder negative doubles.

Misc Auctions

(1♥) P (P) X 1♥ (X) P (1♠)
(2♥) X Penalty P (P) 1NT Minors

1♠ (P) 2♠ (X)
XX Forcing to double or 3♠ (but not if we’ve passes 2♠ response)

(1♦) P (1M) P (2♥) P (3♥) P
(1NT) P (P) X Penalty (P) X Penalty or light
takeout

(1♥) P (1any) X
(2♥) X Penalty

1NT (2suit) X (P) 1♦ (1♥) 1♠ (2♥)
2NT Natural P (P) X (P) Now 2NT = natural

1any (X) P (any bid)
P (P) X Penalty … double is also penalty if they overcalled

General rule: opener’s 2NT is natural, potentially weak hand’s 2NT is takeout.

If we respond in comp, and then reopen(non-jump), it is NF. Must double or cuebid to
force (even if they preempt and we reopen on high level).
