Open 1d641o

1. The first bet in a poker hand, or the action that begins the hand.

E.g. 646v66

Think of the "opening bet" in relation to the blinds, which are "forced bets."

So, in a game of $10/20 NL, when the player first to act raises the action to $60, you might hear this described like, "UTG opens the action to $60."
