Where you open from

The same hand means something different from the first seat than from the last.

The more players still to act behind you, the likelier one of them holds something strong.

Around 15% from under the gun, around 45% on the button. Get that gap into your hands.

• position

  Where you sit relative to the action. Acting later means deciding with more information, which is worth more than most cards.

• range

  All the hands a player could hold in this spot, not just one guess. Decisions are made against the whole set.
