String bet
Putting chips in the pot in more than one motion without first announcing the total amount. Under standard rules only the first motion counts, so a string bet becomes a call rather than a raise. The rule prevents players from reading reactions between motions.
Frequently asked questions
What is a string bet in poker?
Putting chips into the pot in more than one forward motion, without having stated the total first — betting some chips, then reaching back for more. The usual ruling is that only the first portion stands.
Why is it forbidden?
Because it lets a player gauge a reaction mid-bet and then increase the amount. The rule keeps betting as a single committed act rather than a negotiation.
How do you avoid a string bet?
Say the amount before you touch your chips — 'raise to 400' — and the verbal declaration governs however many trips your hands make. Otherwise, move the full amount in one clean motion. Pushing a single large chip without declaring is also a trap: unless you said 'raise', it is usually ruled a call.
