14(13+)-16 1NT: often with 5 card major, rarer 6 card minor or singleton A/K/Q.

2C = 6+C, 2D Ask.
2D = Short-diamond, 3415 or 4315 or 4405 or 4414, 2NT Ask.

1 level overcalls 8+ HCP, 2-level sounder.
F1 major-suit free bids in comp. at 2-level.
Preempts: Wide range (could be good or bad) if parter is a PH, may be quite light if NV.

Opening Leads AND Leads in the Middle of the Hand

Vs. NT:
- 4th best except for Hx(x).
- Often lead high or second high from bad suits.
- Partner's suit: High from xxx if raised, others the same.
- K asks count or unblock, and A or Q asks attitude.
- Std. hornor leads (J from AJT/KJT).
- Occ. lead incorrect honor or spot.

Vs. Suit:
- 3rd from even, low odd.
- Partner's suit: High from xxx or xxxx if raised, others the same.
- K asks count or unblock, and A or Q asks attitude.
- Std. hornor leads (A from AK, J from AJT/KJT).
- Occ. lead incorrect honor or spot.

Following:
- Return: Count first, often 3rd/5th of current cards.
- Switch: Generally attitude, 3rd/5th under honor, top from bad suits.

Defensive Signals

Vs. NT:
- Priority: UD Attitude -> Std. Count -> Suit Preference, vary with logic.
- Lavinthal discard: Discourage the discarding suit, high prefers higher suit, low prefers the lower.
- Smith echo when suitable: High in declarer's first suit encourage the opening lead suit.
- Count in partner's suit if dummy wins trick-1.

Vs. Suit:
- Priority: Std. Attitude -> Std. Count -> Suit Preference, vary with logic.
- Std. discard: high encourage, low discourage.
