When to Cover Touching Honours
When declarer leads from a sequence of touching honours, do not cover the first one. Wait and cover the last touching honour to build winners for your side.
The basic rule of defense is "Cover an honour with an honour." However, this rule changes drastically when declarer or dummy leads from a sequence of touching honours (like Q-J-10 or J-10-9). If you hold a higher honour (like the King), you should not cover the first card in the sequence. Instead, you must wait and cover the last touching honour led from that hand.
Why delaying the cover works
When you cover an honour, your goal is to force declarer to play two of their high cards to capture one of yours, thereby promoting an intermediate card (like a 9 or 8) in partner's hand.
If dummy holds Q-J-10 and leads the Queen, covering immediately with your King allows declarer to win the Ace. Declarer still has the J-10 as established winners! But if you play low on the Queen, and low on the Jack, and only cover the 10 with your King, declarer is forced to use their Ace much later. This delay often promotes partner's hidden 9 or 8 into a master trick.
A worked example: Waiting for the Jack
Dummy (North):
Q J 10 5
You (East):
K 4 3
The Play:
Declarer leads the Queen from dummy.
Caption: You hold the King. Do not cover! Play the 3. The Queen wins.
Declarer now leads the Jack from dummy.
Now you play the King! Declarer must play the Ace from their hand to win. By waiting to cover the second touching honour, if partner holds the 9-x-x-x, partner's 9 is now the highest unplayed card in the suit!
Four common mistakes
- Covering the very first touching honour out of instinct, wasting your King and leaving dummy's remaining honours as winners.
- Failing to recognize what constitutes a "touching" sequence (e.g., K-Q, Q-J-10).
- Waiting too long and never covering at all, allowing declarer to win cheap tricks.
- Covering when you know partner has a singleton or void, meaning there are no spot cards left to promote.
When the rule does not apply
If the sequence of touching honours is short (e.g., dummy holds Q-J doubleton), you often must cover the very first honour led. If you duck, dummy will simply win the trick and won't have another honour to lead, letting declarer escape without ever using their Ace.
Key takeaways
- Do not cover the first card in a sequence of touching honours.
- Wait and cover the last touching honour played.
- Covering forces declarer to spend two high cards for your one.
- This technique promotes partner's 8s, 9s, and 10s into winners.
