Position

One of the first terms you hear bandied about at the poker table is "position" -as in "I've got position on you," or "I hate getting this hand in early position."
Position in poker refers to where a player sits in reference other players. If someone says "I've got position on you" -- it means he's sitting to your left, and will always act after you. Most often, position is used to define where a player sits relative to the dealer and whether you'll be first or last to act in a round of betting.
