When to Go Alone in Euchre

What going alone is worth

When you name trump you may declare that you will play alone. Your partner turns their cards face-down and sits out, and you play the five tricks against both defenders. On CardCouch, as in standard Euchre, only the maker can go alone, and the payoffs are:

• All five tricks alone: 4 points. This is the whole reason to do it.
• Three or four tricks alone: 1 point. The same as an ordinary make. You gained nothing for the risk.
• Fewer than three tricks: euchred. The defenders score 2, exactly as they would against a partnership.

Notice the shape of that table. A loner that takes four tricks is a failure: you scored 1 point where a partnership would probably have scored 2 for the march. The only hand that should go alone is one that expects to take all five tricks without help.

The one-loser test

Look at each of your five cards and ask: can this card lose a trick? A card is a loser if some card an opponent might hold can beat it. The right bower never loses. The left bower loses only to the right. The trump Ace loses to either bower. An off-suit Ace loses to any trump if an opponent is void, which happens more often than you would like. A trump King or Queen is a probable loser unless you also hold the cards above it.

Now count. With five cards there are six defender trumps and three off-suit Aces you do not hold that might be out against you. If you can name at most one card in your hand that could plausibly lose, the hand is a loner. Go alone. If you can name two, the hand is a good partnership make, and your partner's cards are the way to cover those two losers.

Hand shapes that pass

• Right, left, and the trump Ace with any two side cards. Lead the three top trumps, pull every defender trump, and your side cards win because nobody can trump them. Even two 9s as side cards usually take the last two tricks once trump is gone.
• Four trumps headed by a bower, such as right, Ace, King, 10 of trump plus an off-suit card. Only the left bower can beat you, and it is a single loser. Lead the right first to try to drop it.
• Three trumps headed by a bower plus an off-suit Ace. Right, Ace, Queen of trump with an off-suit Ace and a low card is a borderline loner: the trump Queen and the low card are both possible losers. With the left bower instead of the Queen, or an Ace in place of the low card, it qualifies.

Hand shapes that fail

• Both bowers but nothing else in trump and three off-suit cards. That is two sure tricks and three possible losers. Fine to call, not to go alone.
• Five trumps with no bower. Two bowers are out against you, and either one beats your Ace. Two losers.
• Three trumps and two off-suit Kings. Kings are not Aces. Each one can be beaten by an Ace or a trump.

Position changes the maths

As dealer, a loner is easier to judge. If the up-card is ordered up to you or you pick it up yourself, you know exactly what your five cards will be after the discard. Discarding a lone off-suit card also creates a void, which turns a small trump into a trick-winner when that suit is led. Many of the best loners are dealt as four decent cards plus an up-card bower: pick it up, throw the weak off-suit, and go.

In first seat (to the dealer's left) you order up with the knowledge that the dealer now holds the up-card. If the up-card is a bower, ordering it up alone hands the dealer a strong trump that will be played against you. A first-seat loner should already be a loner before the up-card enters the dealer's hand, which usually means you hold both bowers yourself.

The lead matters too. If you go alone as dealer, the player on your left leads and you play last to the first trick, which is ideal for a hand that wants to draw trump on its own terms. If you go alone from first seat you lead: good when you hold both bowers, worse when you hold one and want to see what falls.

Let the score decide

Euchre is played to 10 points, and the value of a loner depends entirely on how many points you still need.

• At 9 points: never go alone. One point wins the game. A partnership make is enough, and a loner only takes your partner's cards out of play.
• At 8 points: almost never. A 2-point march with your partner wins the game, and a 1-point make leaves you at 9 with the deal passing. Only a stone-cold loner (right, left, Ace, plus two more trumps, say) is worth it, and even then the march would have won anyway.
• At 6 or 7 points: a loner that hits puts you at or over 10. This is where good loners earn their keep.
• Far behind, say 4 to 9: the gamble is right. A partnership march gives you 6-9; a loner gives you 8-9 and a real chance. Lower your standard to hands with one clear loser and a second unlikely one, because playing safe simply loses slowly.

Why your partner is worth more than you think

New players see a loner as free upside. It is not. When you go alone you lose five cards that were on your side, and on average two of them are trumps. A partner with a single trump can ruff the off-suit lead that would otherwise beat your King. A partner holding the left bower covers the one loser in your four-trump hand.

Concretely: a hand with two losers played alone fails often enough that it scores less than 2 points on average. The same hand with a partner marches often enough, and is euchred rarely enough, that it averages more. Going alone with a two-loser hand is a bet that loses money over a long game, even though it wins the occasional hand spectacularly.

Worked examples

Defending against a loner

When an opponent goes alone your goal shifts. You are unlikely to euchre a real loner, so the practical target is one trick: it turns 4 points into 1. The tools:

• Lead your off-suit Ace on the first trick if you have the lead. The lone hand has not yet drawn trump, and an Ace wins unless the maker is void. This single lead stops more loners than anything else.
• Hold your highest trump as long as possible. If you have the left bower or the trump Ace, do not spend it under the right bower. Wait for the trick where it wins.
• Keep a card in the maker's short suit. A loner with one off-suit card needs that card to win at the end. If you hold a higher card in that suit, you take the fifth trick.
• Signal nothing. Discard your lowest cards first and keep any suit guarded in which the maker might need a trick.

Some home games use a defender alone or "Canadian loner" rule, where one defender may also play without their partner and scores 4 points for euchring a lone maker. CardCouch plays standard rules: only the maker may go alone, and a euchre against a loner scores the usual 2 points.

Common mistakes

• Going alone because you have the right bower. One sure trick is not a loner. Count the other four.
• Counting Kings as winners. An off-suit King loses to the Ace and to any trump. Treat it as a loser unless you have already seen the Ace.
• Ignoring the up-card. Ordering up a bower alone from first seat gives the dealer the card most likely to beat you.
• Going alone at 8 or 9. The extra points are worthless and the risk is real.
• Never going alone. The opposite mistake. A hand with zero losers at 5 or 6 points is a game-winning swing you should not decline.
