How to Lead Top of a Sequence
Holding K-Q-J or Q-J-10? Lead the highest card to give partner complete clarity and deny higher honours.
When making an opening lead in a suit containing three or more touching honours (such as K-Q-J, Q-J-10, or J-10-9), always lead the highest card of the touching sequence. Leading top of a sequence denies holding any higher honour card in that suit while guaranteeing holding the card immediately below it.
Why leading top of a sequence works
Defenders cannot see each other's hands. Opening leads are the primary communication channel between defensive partners.
If you lead the ♠Q from a ♠Q-J-10 sequence, partner knows instantly that you do not hold the ♠K or ♠A (denying higher honours), but that you do hold the ♠J (promising the card below). Partner can play their own cards with complete certainty, while declarer cannot fool your defensive team.
A worked example: Leading top of a Queen sequence
You are sitting West on defense against South's 4♥ contract.
Your Hand (West):
♠ Q J 10 4
♥ 8 3
♦ K 7 2
♣ 9 5 2
Play of the Trick:
You select Spades as your opening lead and play the ♠Q.
Dummy (North) shows: ♠ A 6 3
Partner (East) holds: ♠ K 8 5
*Caption:* Your ♠Q lead tells partner that you hold the ♠J and ♠10, but NOT the ♠K or ♠A. Partner sees the ♠A in dummy and knows you hold the remaining honours, enabling partner to hold onto their ♠K to capture declarer's ♠9 later.
Four common mistakes
- Leading a low card from a Q-J-10 sequence, leaving partner guessing who holds the missing honours.
- Leading the bottom card of a sequence (e.g., leading the 10 from Q-J-10).
- Leading top from a broken sequence like K-J-10 (lead the top of the interior sequence, the Jack, instead).
- Failing to lead a solid honour sequence when partner has not bid.
When the rule does not apply
When leading a suit that your partner bid during the auction, lead the top card from a doubleton (e.g., lead the 8 from 8-3) even without honours to show partner your suit length.
Key takeaways
- Lead the top honour from three or more touching cards (e.g., King from K-Q-J).
- Denies higher honours, promises the honour immediately below.
- Gives partner instant clarity regarding missing high cards.
- Avoid leading low from solid honour sequences.
