Defending against a loner in Euchre

By Marya · Updated by Holger in September 2026

At the start of each Euchre hand, every player gets a turn to name the trump suit. During this turn, the player can also decide to "go alone". That means their partner sits out the hand! If they go alone and take every single trick (all 5), they get 4 points instead of the usual 1 or 2. That can be enough to win the game. It's the reason so many players try for it, even when it's not a sure thing.

If your hand is a "laydown loner", you hold all the highest trump cards. That's both bowers and the Ace, King, and Queen of trump. It's unusual to get such a nice hand! In that case, no matter what cards the opponents play, you'll win every trick.

It's more common to have a hand that has the potential to be a loner if luck is on your side. That's the type of loner you'll more often find yourself defending against when playing Euchre.

One defense strategy is leading with a long suit

With the right mix of luck and strategy, you can sometimes defeat a loner. But you have to be careful! Here's a video of a hand where the loner could have been defeated if only we'd used the right tactic.

Let's take a look at what went wrong.

My partner is the dealer. Everyone passes on the up card, the Jack of Clubs. On the second time around, everyone passes on calling trump until it's third seat's turn to call or pass. Third seat (sometimes called "third chair") is the third player to choose, the one to the right of the dealer.

Third seat calls hearts as trump! Not only that, they "go alone". Their partner sits out the hand. With their partner out, I'm the first person to play a card.

There are a couple of things to keep in mind here. First, my team shouldn't give up hope, assume the loner will work, and mindlessly play any card. True, our defense may be hopeless. But if we give up and don't think about our strategy, we'll only have luck on our side. Let's hope for luck and play with skill.

With that in mind, I have a choice. Which card should I lead? I have a single heart, a single spade, and 3 diamonds.

If you follow along with the video, you'll see that I played the King of Spades. But it would have been better to lead a diamond. This is my "long" suit, which means I have several cards in it. Why does this matter? Remember that a Euchre deck has only 6 cards in each suit, the 9, 10, Jack, Queen, King, and Ace. I hold 3 of those diamonds and the other 3 are somewhere else. They might be in the other players' hands, in the hand of the player who's sitting out, or still in the deck. Also, one of those diamonds actually counts as a heart. That's the left bower, the Jack of Diamonds. So there are really only 2 more diamonds that aren't in my hand.

If I play a diamond, everyone has to follow suit if they have a diamond. Of all the suits I could choose from, it's most likely that the player going alone or my partner is void in diamonds. That's just because I have several in my hand, so there are fewer to go around.

If I lead from my long suit, I'm hoping that my partner is void in that suit and has a trump card. That opens up a couple of different ways we can spoil the loner!

In the first scenario, the player going alone has a diamond and must follow suit. My partner is void in diamonds, so they can trump the trick and spoil the loner. That would be ideal!

In the second scenario, both the player going alone and my partner are void in diamonds. Then my opponent might play a low trump, which my partner can over-trump.

There's even one more scenario! Suppose both the player going alone and my partner are void in diamonds. My opponent tries to be clever and stops an over-trump by trumping my trick with a bower. Well, my partner can't take the trick anymore. My opponent foiled their chance! You may think we're lost. But in fact, my partner has 2 trumps, the Queen and the Ace. If my opponent leads the next trick with the other bower, my partner will wisely follow with the Queen and hold on to the Ace. Then they'll still spoil the loner.

As you can see, there are sometimes ways to stop a loner. The next time an opponent goes alone and you're first to lead, think about what you can do to help your partner take a trick. That's one way to defend against loners.
