The opening lead is the key advantage defenders have over Declarer, offering an early opportunity to establish and win tricks before Declarer can execute their strategy.
Selecting opening leads that convey meaningful information about your hand is essential. By doing so, you enable your partner to devise effective plans and make informed follow-up plays. This coordination not only improves your chances of success but also fosters stronger teamwork and more satisfying outcomes for both you and your partner.
Standard agreements for opening leads
1. An honor lead shows the higher of touching honors.
| ♠ K Q 6 | Lead the ♠K. The ♠K and the ♠Q are “touching” or “in sequence.” |
| ♥ Q J T 4 2 | Lead the ♥Q. The ♥Q is the higher of the ♥QJ. |
| ♦ J T 6 | Lead the ♦J. The ten is an honor. |
| ♣ K J T 7 | Lead the ♣J. The ♣J and ♣T are touching. |
| ♠ T 9 4 2 | Lead the ♠T. Yes, the T and 9 in sequence are treated like honors for the opening lead. |
| ♥ Q T 9 4 2 | Lead the ♥T. The ♥Q and the ♥T are not touching, so don’t lead the ♥Q. The ♥T and the ♥9 are in sequence. |
| ♦ A T 9 8 5 | Lead the ♦T. Again, the ten and nine are in sequence. |
| ♣ A K 9 5 | Lead the ♣A. Many partnerships lead the K from both an AK combination and a KQ combination. That leaves partner in doubt. She can’t tell if a king lead is from an A-K or from a K-Q. It’s important for beginners to remove doubt whenever they can, so I recommend you ask partner to adopt the agreement that you will lead A from AK. |
2. A spot card shows if you have an honor or two in the suit…
- low spot says “Yes, I have an honor.”
- high spot says, “No, I do not have an honor.”
It is your partner’s responsibility to determine whether the spot card you lead is a low or high card. To make this assessment, they will need to analyze all the spot cards visible to them after the first trick has been played. This careful evaluation helps your partner interpret your lead and plan the subsequent play effectively.
| ♠ K 7 6 | Lead the ♠6. You would like to have a lower card than the 6 so it would be easier for Partner to tell that your card is indeed “low.” |
| ♥ Q T 4 2 | Lead the ♥2. |
| ♦ J 5 3 | Lead the ♦3. |
| ♣ K J 8 7 | Lead the ♣7. You have to lead a “low” card that might not look “low” to Partner. |
| ♠ 8 4 2 | Lead the ♠8. |
| ♥ 8 7 6 5 4 | Lead the ♥8. |
| ♣ A K 9 5 | Lead the ♦5. |
3. If you have more than 4 cards in a suit with an honor, lead the 4th best.
| ♠ K 7 6 5 3 2 | Lead the ♠5. |
| ♥ Q T 4 3 2 | Lead the ♥3. |
| ♦ J 9 8 7 5 3 2 | Lead the ♦7. |
| ♣ K J 8 6 5 | Lead the ♣6. |
4. Lead high from any doubleton.
| ♠ 9 6 | Lead the ♠9. |
| ♥ Q 2 | Lead the ♥Q. When partner sees the Queen, she may think you have led from touching honors (from the ♥QJ). She may not be sure what you have until you play another card. Or maybe she’ll see the ♥J in her own hand or the Dummy. Then she’ll know what your lead means. |
| ♦ 3 2 | Lead the ♦3. You would prefer to have been dealt a higher spot card than the 3. But you have to make do with what you have. Partner may think the 3 is “low.” It will be clear after you later play the 2 that your 3 was not your lowest spot card. |
| ♣ K J | Lead the ♣K. This is another lead that might look like “higher of touching honors” to Partner. It’s not good to confuse Partner. So you should seriously consider leading another suit. |

It’s understandable to feel unsure about which suit to lead when faced with four options—it can indeed be a challenging decision. The best way to approach this is by considering the context of the auction and the cards in your hand. If your partner has bid a suit, leading that suit is often a good starting point. Alternatively, if you have a suit with a strong sequence, such as a group of high honors, it can be advantageous to lead that suit to try and establish tricks early.
Paying attention to the opponents’ bidding can also provide valuable clues; for example, avoiding a suit where Declarer has shown strength. When the choice isn’t clear, a more neutral or safe lead can help minimize risk. With practice, selecting the right suit will feel less overwhelming and more intuitive.
That’s absolutely correct—understanding which card to lead within a suit is only useful if you first know which suit is the right one to lead. Choosing the appropriate suit is a crucial decision that can set the tone for the entire defense. It requires careful consideration of the bidding, your hand, and any signals or information shared by your partner. Mastering this aspect of the game not only enhances your effectiveness as a defender but also strengthens the partnership’s ability to work together strategically.
Let’s start with…
The suit to lead against notrump contracts
In many hands, success hinges on which side can establish and cash their tricks first. Essentially, it becomes a race to set up your long suits or high honors before Declarer can do the same. Opening leads designed to quickly establish tricks are often referred to as attacking or active leads, as they aim to gain an immediate advantage.
However, there are also situations where a more cautious approach is necessary. In these cases, patience is key, and a passive lead—choosing a suit without significant length or honors—is the better strategy. This approach minimizes the risk of giving Declarer an unnecessary advantage while allowing the defense to wait for an opportunity to capitalize later in the play. Understanding when to adopt an active or passive strategy is critical to becoming an effective defender.
Active leads
When your opponents have settled in a notrump contract, you may not be able to defeat them based on your high cards alone. But if you can establish extra winners in a long suit (skaters), your chances improve greatly.
So our first rule for opening leads is…
Lead the suit that is the longest and strongest in the combined hands of the partnership. Save your high cards in other suits to recapture the lead after your long suit has been established.
You can’t always tell which suit is longest and strongest because you see only your own hand, and not partner’s. Even so, the guesswork involved can be greatly reduced if you pay attention to the bidding.
Example 1
| You ♠ A Q 8 6 4 ♥ 9 2 ♦ 5 4 3 ♣ K 7 2 |
The contract is 3NT. Partner has not bid.
If partner has not bid, lead spades. You hope spades is the longest and strongest suit in your hand and partner’s hand combined.
But if partner has bid, make your opening lead in partner’s suit. Yes, even if partner’s suit is hearts, lead it, despite having only a doubleton.
Remember, it’s better to lead toward honors than to lead away from them. In the heart suit, you’ll be leading toward partner’s honors instead of leading spades away from your spade honors.
Example 2
| You ♠ A Q 8 6 4 ♥ 9 ♦ K J 3 ♣ 9 7 6 2 |
The contract is 3NT. Partner bid hearts.
With a singleton in partner’s heart suit, and a likely side suit winner for an entry (diamonds here), lead your own long, strong suit.
Example 3
| You ♠ K J 8 6 4 ♥ J 3 ♦ A 8 3 ♣ T 6 2 |
The contract is 3NT.
Partner has bid hearts and raised your spades.
Lead spades, the suit partner raised. You have an entry (♦A) for your spade skaters after you have established the suit.
Example 4
| You ♠ 8 4 3 ♥ 8 7 5 ♦ K Q J T 9 ♣ A 7 |
The contract is 3NT. Partner has bid hearts.
When you can defeat the contract without partner’s help, make an opening lead in your own suit.
Lead diamonds to drive out the ♦A. Then recapture the lead with the ♣A to cash the setting tricks.

Lead partner’s suit in preference to your own, unless…
✔ Partner raised your suit, or…
✔ You only have a singleton in partner’s suit, or…
✔ You can defeat the contract without partner’s help
It would be nice if we were always dealt a long, strong suit. It would make opening notrump leads easy. But some hands just don’t fit our guidelines. For example…
Example 5
| You ♠ Q 8 6 4 3 ♥ 8 5 ♦ 9 3 ♣ K Q J T |
The contract is 3NT. Partner didn’t bid.
What kind of opening lead do we make when our long suit is not our strong suit?
It’s usually better to lead the strong suit. You can take three tricks in clubs after the ♣A is gone, but you may not take any tricks at all in spades.
Example 6
| You ♠ A 3 ♥ K Q 9 6 5 ♦ 9 8 7 ♣ Q T 6 |
The contract is 3NT. Partner didn’t bid. Declarer bid hearts.
Does it matter that declarer has bid our best suit?
Yes, it definitely does matter. We’ll get to what you should lead in a minute. But what I want you to focus on now is that you should AVOID leading declarer’s suit. Hearts would be the worst suit to lead.
What if dummy bid hearts? Would we still AVOID an opening lead in our long heart suit?
Yes! The main reason for an opening lead in our longest and strongest suit is we hope to take tricks with our small cards after the opponents run out of the suit – we want skaters. But when they have bid the suit, they are unlikely to run out.
In addition, declarer will have the advantage of playing last with whatever honors he has in our suit.
Opening leads to avoid…
✔ Suits bid by your opponents, especially declarer.
✔ Weak long suits when you don’t have enough entries to establish and cash them.
✔ 3-card or 4-card suits with only one honor.
✔ 3-card or 4-card suits headed by A-Q or K-J. This kind of broken honor sequence is called a tenace.

“Wait a moment! If I avoid all those options, what’s left for me to lead?”
That’s an excellent question! What remains is a completely different approach to opening leads, known as passive leads. These leads are designed to avoid giving Declarer any unnecessary advantage. Instead of trying to immediately establish tricks or attack a potentially strong suit, a passive lead focuses on minimizing risk. It’s a thoughtful strategy, ensuring that you don’t accidentally set up tricks for Declarer while waiting for a better opportunity to gain the upper hand later in the play.
Passive leads
Example 7
| You ♠ 9 7 3 ♥ T 6 5 2 ♦ Q 8 7 ♣ A 9 6 |
The contract is 3NT, and your partner remained silent during the bidding while Declarer showed strength in hearts.
You might think, “This is tough—I don’t have a longest and strongest suit to lead, and my partner hasn’t given me any clues. What should I do?”
First and foremost, avoid leading hearts. Leading Declarer’s suit would only make it easier for them to establish their tricks in hearts, giving them a significant advantage. Instead, consider looking for a safer, more neutral option that doesn’t directly help Declarer’s strategy, giving your partnership a better chance to gain control of the hand as the play unfolds.
Second, avoid leading away from a single honor in any suit. Doing so could easily hand Declarer an additional trick. For example, if Declarer intends to finesse in diamonds, they might lose to your ♦Q if you wait for the finesse to occur naturally. However, if your opening lead is a diamond, Declarer will play last on that trick, eliminating the finesse and denying you the chance to win with your ♦Q. Similarly, leading away from the ♣A could result in a lost opportunity to secure a trick.
In this scenario, the recommended opening lead is the ♠9. If your partner holds any honors in spades, your lead will work toward them, creating a potential advantage. On the other hand, if your partner does not have any spade honors, Declarer would likely take all the spade tricks regardless. In this case, no harm is done by leading the ♠9.
This lead is an example of a passive lead, often referred to as a protecting lead. The idea is to safeguard your honors by waiting for the right moment—letting someone else lead those suits instead of risking your honors prematurely. This thoughtful approach helps maintain control and minimizes the risk of giving Declarer an unnecessary advantage.
Example 8
| You ♠ 7 5 3 2 ♥ Q T 5 2 ♦ 7 5 3 ♣ A 9 |
The contract is 3NT. Partner didn’t bid. Declarer bid hearts.
Which is a better passive lead – a three card suit or a four card suit?
Longer suits make safer passive opening leads because they are less likely to help declarer establish skaters.
Lead ♠7 in preference to the ♦7.
Example 9
| You ♠ 7 5 3 ♥ K 7 5 3 ♦ 7 5 3 ♣ A 5 3 |
The contract is 3NT.
Declarer opened 1N. Dummy raised to 2N, and declarer went on to the 3N game. What’s your opening lead?
Avoid leading from a three- or four-card suit that is headed by only one honor, as this can often give Declarer an unnecessary advantage. In this case, a passive opening lead is the best option. At first glance, your spades and diamonds might appear equally viable, making it seem like either suit could be chosen at random. However, the decision is far from arbitrary.
Take a closer look at the bidding. Why didn’t your opponents explore the possibility of a major suit fit? Likely because, after evaluating their hands, they determined there weren’t enough cards in the major suits to establish a fit. This information increases the likelihood that your partner has more spades than diamonds.
With this reasoning, your opening lead should be the ♠7. It’s important to remember that what wasn’t bid can be just as informative as what was. Paying attention to these subtleties in the auction can guide you to more effective decisions, helping your partnership gain the upper hand during play.
Example 10
| You ♠ A T 4 ♥ K 8 5 3 ♦ K 9 6 ♣ Q J 2 |
The contract is 3NT. Dummy bid hearts.
We have no longest and strongest suit. It looks like we need a passive opening lead to protect our honors.
Actually, a three card suit headed by two honors in sequence is OK, if nothing better is available. Lead the ♣Q.
The safest passive opening leads…
✔ a worthless 4 card suit.
✔ a worthless 3 card suit.
✔ a 3 card suit headed by two honors in sequence.
✔ a low doubleton.
Sometimes the bidding will suggest which of these is best. We’ll get to that in a minute, but first…
Review and practice for notrump opening leads
Example 11
| You ♠ 7 2 ♥ A J T 7 ♦ K T 6 5 4 ♣ 9 8 |
The contract is 3NT. Partner did not bid.
Partner did not bid, so lead your own suit.
What is your opening lead, the ♥J or the ♦5?
Example 12
| You ♠ A Q T 7 5 ♥ 8 4 3 ♦ K T 8 ♣ 7 6 |
The contract is 3NT. Partner bid hearts.
You have a long strong suit, and a side suit entry to recapture the lead after your suit is established.
Is your opening lead the ♠7?
Example 13
| You ♠ J ♥ Q 9 5 4 ♦ K Q T 7 ♣ Q 9 5 4 |
The contract is 3NT. Partner bid spades. Declarer bid diamonds.
Avoid a diamond lead. That’s declarer’s suit.
Do you lead from one of your other four card suits, or do you lead your singleton in partner’s suit?
Example 14
| You ♠ 7 6 ♥ Q 9 4 ♦ J 8 7 ♣ K 9 7 5 4 |
The contract is 3NT. Partner didn’t bid.
When no suits have been bid, your opening lead can be your own longest suit.
Do you lead the ♣5, or something else?
Example 15
| You ♠ T 2 ♥ 8 4 3 ♦ K J 8 7 ♣ A Q 6 5 |
The contract is 3NT. Partner didn’t bid.
Clubs and diamonds are your longest and strongest suits, though they are only four card suits.
What are our guidelines for opening leads from four card suits not bid by declarer’s side?
Example 16
| You ♠ K 2 ♥ 7 3 ♦ A J T 7 4 2 ♣ K Q 5 |
The contract is 3NT. Partner didn’t bid.
Nice hand! There’s a good chance you’ll be able to set this 3N contract – if you get off the the best opening lead.
What’s your choice?
Example 17
| You ♠ A K 9 5 4 ♥ 8 ♦ T 7 4 2 ♣ Q 7 5 |
The contract is 3NT. Partner didn’t bid.
You have a nice spade suit, but you only have a mild hope of a side suit entry.
I’ve peeked at the cards, and I can tell you that partner doesn’t have any high cards in spades. I can also tell you that you have a good chance to set up and cash spade skaters.
What has to happen for you to get four spade tricks?
Listen to the bidding
Example 18 – the unbid suit
| West | North | East | You |
| – 1♠ 2♠ P | P P P P | 1♣ 2♥ 3N | P P P |
What do we know from the bidding? Well… we know a lot, actually.
Why did East choose notrump and not a spade contract?
You inquire what the 2♥ call shows, and West explains that in their partnership it shows a medium strength hand. A 3♥ rebid would have shown a maximum.
Interesting. That means East-West do not have enough power to bid game. So where does East think his tricks are coming from?
Which suit will East’s skaters come from?
What would be the only reason to lead a heart instead of the obvious diamond suit?
| You ♠ T 4 ♥ K J T 9 8 ♦ 8 5 2 ♣ 9 7 5 |
After considering the bidding (example 18, above), let’s look at your actual hand. What’s your opening lead for this hand?
When your opponents have bid three suits and settled into a NT contract, it’s usually right to lead the unbid suit. This is especially true if it’s a major.
Example 19 – no suits have been bid
| West | North | East | You |
| – 2N P | P P P | 1N 3N – | P P – |
When the responder invites game and the opener accepts, it may initially seem like their bidding provides no clues about the suits they hold, especially since no specific suits were mentioned during the auction. However, this assumption isn’t entirely accurate—there are subtle inferences you can draw.
Opener typically won’t have a five-card major when starting with a 1NT bid. This is because a five-card major would usually prompt a different opening bid or a transfer sequence. However, it’s not uncommon for the opener to hold a five-card minor, and in some cases, even a six-card minor. This means the opener’s distribution is often weighted more heavily toward the minor suits.
Recognizing this tendency can help you refine your defensive strategy, particularly when deciding on an opening lead or anticipating how the play might unfold. Understanding the nuances of the 1NT structure allows you to make better-informed decisions throughout the hand.
Why didn’t responder bid stayman?
Responder will often raise a no-trump bid when holding a long minor suit but rarely bids no-trump while concealing length in a major suit. This means that responder’s hand is typically more oriented toward the minor suits rather than the majors.
This tendency is rooted in the strategic approach to bidding. With a long major suit, responder would usually take steps to reveal it, either through direct bidding or by employing a transfer or other conventional sequence. In contrast, long minor suits are often more compatible with no-trump play, making a raise to no-trump the preferred option.
Understanding this bias can provide valuable insights during the play of the hand. It helps you anticipate the distribution of suits between Declarer and Dummy, guiding your defensive choices and allowing you to adjust your strategy accordingly. Recognizing these patterns improves your ability to work effectively with your partner to counter Declarer’s plan.
Without even knowing what your hand is, what should be your opening lead?
Example 19 (continued)
| You ♠ 3 ♥ 8 6 ♦ K J 8 6 2 ♣ K Q 7 6 5 |
Remember, 3NT – no suits have been bid.
The preference for major suits in bidding suggests that the best opening lead is not from one of our own suits but rather the ♥8. This choice is informed by the opponents’ bidding, which indicates their strength lies in the minor suits rather than the majors. It’s important to avoid leading suits shown to be strong for Declarer, as doing so would likely aid their plan. Instead, selecting a suit outside of Declarer’s likely holdings offers a safer and more strategic start to the defense.
Example 20 – stayman
| West | North | East | You |
– 2♣ 3N | P P P | 1N 2♠ P | P P P |
Responder likely felt some disappointment in not locating a heart fit. However, their use of Stayman has inadvertently provided the defenders with valuable information about both Declarer and Dummy’s hands. A perceptive defender will take this information into account when deciding on an opening lead.
The question now arises: does the typical preference for leading a major suit against a 3NT contract hold enough weight to override the knowledge that both Declarer and Dummy have four-card major suits? Should a major suit still be the preferred choice when the decision is a close call? These are crucial considerations, as selecting the right suit can significantly impact the effectiveness of the defense. Balancing general principles with specific inferences from the bidding is key to making an informed and strategic decision.
Opening leads against suit contracts
Many of the considerations for opening leads against suit contacts are the same as for opening leads against notrump. There are, however, two main differences.
- Don’t bother trying to set up your long strong suit for skaters. Even if you succeed in setting it up, declarer will trump your skaters.
- The defenders can trump too. So leading short suits, trying for an early ruff, holds promise that doesn’t exist for notrump contracts.
Good opening leads against a suit contract…
✔ lead a singleton, preparing to trump the second round. Note that this is only good if you have a trump card to use for ruffing, and if partner can lead the suit back for you to ruff.
✔ lead partner’s short suit so she can ruff before declarer pulls trump. For this to work, you may need an early round trump winner so you can lead the original suit again before declarer finishes pulling partner’s trump cards.
✔ lead your own suit if partner raised it.
✔ lead partner’s suit
✔ lead the top of an honor sequence. An ace-king sequence is among the best opening leads because you will win the trick and get to see both the dummy and partner’s attitude card to the first trick, either of which may guide you to the best defense. Other two-card sequences are risky, while three-card sequences are far safer.
✔ make a passive or protecting lead in a side suit where you have no honors.
Example 21
| You ♠ K Q 3 2 ♥ Q 8 6 ♦ A J T 9 ♣ 7 3 |
The contract is 4♥. Partner didn’t bid.
Decide if each of these opening leads is good or bad. Then read the comments for each one.
Example 22
| You ♠ 5 ♥ 9 7 6 ♦ Q J T 7 3 ♣ 8 7 4 3 |
The auction was 1♥ – 3♥ – 4♥. What’s your lead?
Be sure to read the comments for all four opening leads.
Example 23
| You ♠ J 8 5 ♥ Q J T 8 ♦ 7 3 ♣ K Q 4 3 |
The auction was 1♠ – 2♠.
You have honor sequences in hearts and clubs, and a good passive lead in diamonds. What do you think of each of these opening leads?
Example 24
| You ♠ 2 ♥ K 4 3 2 ♦ A 4 3 2 ♣ Q 4 3 2 |
The contract is 4♠. No side suits were bid.
A singleton trump makes a poor opening lead. And you should avoid opening leads from suits headed by a single honor.
But you have to lead something, even when none of your choices are good.
Leading away from a high honor carries a greater risk of giving Declarer an unnecessary trick. In this case, the ♦2 would be the most problematic opening lead, while the ♣2 is a slightly safer option (though it’s hard to call it ideal). Regardless of which lead you choose, the outcome is likely to be unfavorable unless you’re fortunate enough to find your partner holding a supporting honor in the suit. Defensive success in such situations often depends on both careful reasoning and a bit of luck.
One additional note for example 24…
If, for whatever reason, you decide to lead diamonds, you should choose the ♦A, not the ♦2. At least you’ll get a trick out of your bad opening lead. And you may be able to shift to a better suit for the next trick after you see partner’s attitude card and the dummy.
Don’t confuse this with a “good” opening lead. It’s not. It’s just better than the ♦2.
Listen to the bidding
Sometimes the bidding tells you what opening lead to make. Let’s look at some examples.
Example 25
| West | North | East | You |
– 1N 3N | – P P | 1♠ 2♣ – | P P – |
Declarer has 5 spades, yet responder chose clubs as trumps. That means dummy is short in spades. Declarer may well plan to trump spade losers in dummy. So…
Lead trump. And if you can recapture the lead, lead trump again.
Example 25 (continued)
| You ♠ A Q T 8 ♥ Q J T 6 ♦ 5 2 ♣ T 8 2 |
Normally a lead from a three card honor sequence, like ♥QJT, is good. But not on this bidding. Your hand confirms that declarer has spade losers that he would like to trump in the dummy.
Lead clubs as many times as you can. Each club lead saves a future spade trick for you.
Example 26
| West | North | East | You |
– 2♦ 3♦ | – P P | 1♠ 2♠ 4♠ | P P – |
Declarer has a spade suit he bid three times. If he gets the lead he will pull trump and discard his side suit losers on dummy’s strong diamond suit.
So…
Example 26(continued)
| You ♠ T 5 ♥ A Q 8 2 ♦ Q 7 ♣ K T 5 3 2 ; |
Forget the warnings about not leading away from certain honor holdings in the unbid suits. If you don’t cash your winners in clubs and hearts right now, you may never get them.
Lead the ♥A, and look closely at partner’s carding. If she has the ♥K, she’ll play an encouraging card, and you will continue hearts. If she discourages hearts, you’ll shift to clubs.
The bidding told you to take such wild chances with your opening lead.
A compromise for opening leads…
Defense is easier when you can quickly figure out who’s got the high honors in each suit. To that end, beginners should only lead low from a high honor, not from a jack or ten.
When you hold a suit like ♥ J 8 7 3, look for a different suit to lead. You don’t want to lead low from this and have Partner assume you have a higher honor than you actually hold. And you can’t lead the ♥J because that promises the ♥T, which you don’t have.
The solution is…
So if you must lead from a suit headed by the J or T, lead the second highest. Partner will see the high spot card and know you don’t have a high honor.
From ♥ J 8 7 3, lead the ♥8. And tell Partner your opening leads of a low spot card promise a high honor. (Tell her before the game starts, not after you’ve looked at your cards.)
