Quick Summary

Updated March 2026 with the latest strategies and examples.

Opening leads are the first card played by the defender to the left of declarer. Following standard lead conventions helps partner read your hand and plan the defense.

For foundational card play technique, see our guide to finesses in bridge.

Lead the top of a sequence (3+ touching honors):

Holding Lead

KQJ K

QJ10 Q

J109 J

AKx K (then A to show doubleton)

From Broken Sequences

Lead the top of the broken sequence:

Holding Lead

KQ10x K

QJ9x Q

AQJx A (or Q from interior)

KJ10x J (interior sequence)

From Small Cards

Lead 4th best from length:

Holding Lead

K8742 4

Q9653 5

J7432 3

Top of Nothing

From three small cards, lead the top:

Holding Lead

862 8

753 7

This shows no interest in the suit.

Doubleton

Holding Lead

5 5

Leads Against Notrump

From Length

Lead 4th best from your long suit:

Holding Lead

KJ842 4

QJ653 5

A8732 3

From Sequences

Same as against suits - top of sequence:

Holding Lead

KQJ84 K

QJ1053 Q

J10972 J

From AK

Against NT, lead K from AK (asks partner to unblock or give count).

Some partnerships lead A from AK - clarify!

Partner’s Suit

When partner has bid a suit:

Your Holding Lead

Three small Top (then low next)

Doubleton Top

Honor + small Low (4th best if 4+)

Singleton The singleton

Axx A (against suits) or low (against NT)

Supporting Partner

♠862 in partner’s spade suit: Lead 8 (top of nothing).

♠Q62 in partner’s spade suit: Lead 2 (4th best from honor).

Trump Leads

Lead trumps when: - Declarer will be ruffing in dummy - You want to cut down ruffs - No better lead exists

Don’t lead a trump from: - Qxx or Jxx (may cost a trick) - Singleton (gives away position)

Passive vs Active Leads

Active Lead

• From a suit where you have honors

• Trying to establish tricks

• Riskier but potentially rewarding

Passive Lead

• From a safe suit (no honors)

• Waiting for declarer to break suits

• Safer but may give declarer time

Choose based on the auction and your hand strength.

Reading the Auction

They Bid a Suit

Usually don’t lead it (declarer has strength there).

Dummy Showed Support

Consider trump leads to cut ruffs.

They Struggled to Game

Be passive - they might go down on their own.

They Blasted to Game

Be active - try to cash tricks quickly.

Standard Count Cards

When following suit (not leading), show count:

Count Play

Even number High-low (4 from 42)

Odd number Low (2 from 742)

This helps partner count the hand.

Standard Attitude

When partner leads: - High card = Encouraging (like the suit) - Low card = Discouraging (don’t continue)

Quick Reference

Against Suits

AK K (A shows different meaning)
