Another variable expert players take into account for a betting decision is their position at the table with respect to the dealer (how many players have acted before you and how many act after you). In [14] the authors emphasize that a later position is better because you have more information available before you must make a decision. Their pre-flop strategy is dependent on a player's expected position in the later betting rounds. For example, they discuss a tactical raise, called ``buying the button", which is used in late position in the pre-flop to hopefully scare away the players behind you to become the last player to act in future betting rounds.
