One Chip Rule

In live games, the “one chip rule” clarifies that any player placing a single chip forward without any accompanying verbal declaration after another player has bet is making a call and not a raise.

For example, in a no-limit hold’em game a player makes a bet of $8 after the flop, then another tosses out a $25 chip without saying anything. The second player’s bet is considered a call of the $8, not a raise to $25. The rule is also sometimes called the “oversize chip rule.”
