What happens if a defender leads out of turn in bridge?
A · Advanced · Irregularities · 2 of 6When a defender faces the opening lead out of turn, declarer may accept or refuse it, or spread their own hand and become dummy. A refused lead stays face up as a major penalty card. A card a defender exposes by accident is a penalty card: a single low card is minor; an honour or a card played on purpose is major.
How it works
- Opening lead out of turn: declarer may accept or refuse it, or spread their hand and become dummy.
- Refused: the card becomes a major penalty card.
- Minor penalty card: a single low card exposed by accident.
- Major penalty card: an honour, or a card exposed on purpose.
- Minor rule: no lower card of that suit may be played before it, but an honour may.
- Major rule: played at the first legal chance; partner may face lead limits.
- Declarer's lead out of turn: either defender may accept it or require a retraction.
- Trick 13: a lead out of turn must be retracted.

Tricky cases
A defender drops the two of clubs. Is it a penalty card?
Yes, a minor one: a single card below honour rank exposed by accident.
Declarer could see dummy's cards before refusing a lead out of turn. What then?
Declarer must accept the lead.
A defender has two penalty cards. How are they treated?
Both become major, and declarer chooses which to play.
Does a declarer's exposed card become a penalty card?
No. Penalty cards apply to defenders only.
Why the rule exists
An exposed card gives partner information, so the rules make it a burden. Declarer's choices after a lead out of turn stop the defenders gaining from it.
