Bids that Require Advance Preparation

2D Multi = Weak Two bid in a major (3-9 HCP, 5-card suit OK) May be very aggressive, particularly at favorable vulnerability.

If 2nd hand passes, responder may pass. Non-vulnerable can be done with any hand, vulnerable would indicate some diamonds

2H/S = 6+H/6+S, approximately 10-13 pts

Over NT, we play:
2C=MM; 2D=1M; 2H=H+m; 2S=S+m; 2NT=5+5+Mm 4-4.5 loser hand
Double = good hand against weak NT, and 4 card major with longer minor against strong NT

1m-2H = Limit raise or balanced 11-12, by UPH

1m-2S = Mixed raise (6-9 pts, 5+ fit) by UPH

1H-2S = Invitational hand with 6+D

1M-3(M-1) = Mixed raise (6-9 HCP, 4+ fit) by UPH

FSJ by PH

Transfers after 1M-(X) starting from 1NT

After 3C preempt – 3D is asking for 3card major

General Bidding Style

5-Card Major, semi-forcing NT.

1NT (14+-17 HCP). With a 5-card M, we open 1NT with 14-15 HCP, 1M with 16-17 HCP.

We open 11 or 12 balanced, and 10-11 Unbalanced. 3rd-seat openings can be as low as 8 and 4-card suit often not vulnerable.

1M-2C = 2+C, GF, start of a relay.

1H-2D or 1S-2D/2H = Rebid of 2M shows 6+M and 14+ HCP (unless 6H4S – then 12+ HCP)

1M-2D & 1S-2H = 5+ GF

GAZILLI after 1M-1NT, 1H-1S

Two-tier splinters, regular splinters 13-16 HCP (1H-3S, 1S-3NT: 8-12 HCP)

We open 1C with 3-3 in minors

We open 1C with 4-4 in minors and balanced (unless 3rd hand where we open with better minor)

Walsh style responses after 1m opening

1NT could have a 5-card Major ONLY if 14-15 HCP.

May respond with very weak hand.

One-level overcalls 8+ HCP. 2-level sounder.

Preempts: wide range (could be good or bad)

Opening Leads AND Leads in the Middle of the Hand

vs NT: 4th best, 2nd or top from bad holdings (10xx(+) can be treated as good or bad), Rusinow from 4+ with the following exceptions:

Not in dummy's suit.
Not in partner's suit.
Not in declarer's suit.
Not in preemptor's side suit.

vs NT: 3rd/5th in partner's suit (unless raised, then top from 3 small)

vs NT: K is power lead and A asks for attitude.

vs suits: standard honor leads

vs suits: 3rd from even or three, lowest from odd, but will lead top from nothing in partner's raised suit. suit preference from known long suits (6-7 card preempts)

vs suits: A from AKx(+) except against 5-level or higher, or AK doubleton, or ready to switch to a side singleton.

Defensive Signals

Upside Down Count and Attitude Signals.

Signaling priority normally: Attitude, Count, Suit-Preference (may vary with logic).

Attitude in partner's suit if dummy wins trick-1 vs NT with A, K, or Q, count otherwise.

Suit preference when dummy has a singleton, middle is ambiguous (no clear preference) - unless necessity to tap dummy is obvious for both.

Suit-preference in trumps if we think partner needs it.

Rev Smith Echo vs NT mostly by opening leader's partner (low encourages opening lead suit), except in obvious count situation.

When splitting honors, we play the second highest if we have two honors (J from QJx, Q from KQx), the highest if we have three honors (K from KQJ, Q from QJ10).

We give true count only if we think partner needs it.
