Leading under the ace: avoid it or dare it?

Leading under the ace means playing a small card in a suit where you hold the ace, without playing the ace. Often risky, sometimes clever.

Why it's risky

Leading a small card under your ace lets an opponent win with a weaker card (king, queen) you would have beaten. Worse, your ace may then get ruffed if the suit comes back. Hence the saying "never under an ace."

When it's still defensible

The saying isn't absolute. Under-leading can be good when:

• Your partner bid the suit: you play toward their strength.
• You want to keep your ace as a safe entry for later.
• You want to force an opponent ruff to read the distribution.

The alternative: cash the ace

When in doubt, playing the ace banks the trick right away and avoids losing it. It's the safe lead when the ace is bare or barely supported. Under-leading is a thought-out play, not a reflex.

FAQ

Why do players say "never under an ace"?

Because leading small under your ace lets an opponent win with a weaker card, and your ace may then get ruffed afterwards.

Is leading under the ace always bad?

No. It can help to play your partner's suit or to keep your ace as a safe entry. It's a thought-out choice, not a rule.
