Bids that Require Advance Preparation

2D over opponent's 1NT = H or S.


1m-2H by UPH is either SJS in H or balanced 11-12.

1m-2S by UPH is either SJS in S or constructive raise in partner's minor.

1H-2S by UPH is either SJS in S or D invitational.

1H-3D by UPH is a mixed raise (in comp also).

1S-3H by UPH is a mixed raise (in comp also).

General Bidding Style

5-card majors, 2/1 GF, forcing NT can have up to bad 14.

1NT: 14-16 HCP at 1st, 2nd and 3rd not vul.

1NT: 15-17 HCP at 3rd vul and 4th.

3rd-seat 1NT/2NT opening can be shaded and off-shape (especially W vs R).

We open 11 balanced (optional when vul), and 10 HCP unbalanced (occasionally 9 HCP with a good 6-card suit).

3rd seat opener could be as light as 8 HCP, 4-card M often.

May respond with a very weak hand (3 to 5 HCP) if we have a fit or a long suit to get out. We almost always respond to 1C opening.

One level overcalls shows 7+ HCP, two level sounder.

Preempts when W vs R can be very bad especially at 1st seat (5-card suit often).

May open/overall a 3-card suit at 3rd seat for lead-directing purpose.

Opening Leads AND Leads in the Middle of the Hand

vs NT: 4th best, 2nd from bad holdings (3rd in partner's suit).

vs NT: 3rd/5th in partner's suit.

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

vs NT: Russinow in a 4-card suit or longer (standard honor leads in partner's suit or dummy's suit).

vs suits: 3rd from even or 3, lowest from odd, but will lead high from nothing in partner's raised suit.

vs suits: A from AKx(+) except against 5-level or higher, or AK doubleton, or ready to switch to a side singleton. Occasionally, we will lead K to ask for count when it's clear the opening leader does not have AK doubleton or side shortness.

Spot leads is 3rd/5th against suits and 2nd/4th against NT during the hand.

vs both: J denies and 10,9 shows 0 or 2 applies in the middle of the hand if we think it's helpful to partner.

Defensive Signals

Upside down count and attitude, standard suit preference and present count. The 2nd card in the same suit tends to be SP.

Upside down discard. The 2nd discard in the same suit tends to be SP.

Signaling priority is Attitude, Suit Preference, Count.

Occasional suit-preference in trumps if we can afford to.

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

Reverse Smith vs NT: low cards in declarer's first suit encourage the opening lead suit (suit preference if attitude to opening lead suit is known) except when it's an obvious count situation (dummy has a long suit without any side A or K).

Suit preference when dummy has a singleton, middle is ambiguous (no clear preference).

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 (K from KQJ, Q from QJ10).

We give true count early in the hand. Later in the hand, our count can be suspect.
