Simply put, three-way betting odds offer three wagering options that focus on regulation time results only. They differ from two-way odds as a TIE is added as a third betting choice. Three-way lines are offered in most competitions where a draw is a possible outcome.
A 3-bet is the third bet in a poker sequence, in which a player re-raises after the initial pre-flop raise, or 2-bet. (The blind payment is the first bet in Texas Hold'em and Omaha.)
