Verbal declaration
In virtually all cardrooms a spoken action ('raise', 'call', 'all-in') is binding the moment it is said, whatever the chips do afterwards. Announcing a bet size before moving chips also protects you from string-bet rulings.
Frequently asked questions
Is a verbal declaration binding in poker?
Yes — an action stated clearly and in turn is binding, even if your chips never move. Saying 'raise to 500' commits you to that amount; saying 'call' commits you to the bet.
Why does verbal take precedence over chips?
Because it removes ambiguity. Chips can be miscounted, dropped or put out in a way that looks like something else, so the spoken word is treated as the real action — which is also why a string bet is avoided by saying 'raise' first.
Which phrases cause trouble?
Anything vague. 'I'll play' or 'your bet' means nothing enforceable, and in some rooms the single word 'bet' with no amount is ruled a minimum. Table talk about what you might do is not binding, but say it in turn and a floor may treat it as action — so keep declarations short and specific.
