Position

Position

Introduction

• Position is a description of how early you act in the hand post flop.
• It is split into 3 groups:
• Early
• This is when you are one of the first to act in the hand.
• The blinds are usually in early position.
• Middle
• You act somewhere in the middle. People have acted before you, but some people are yet to act.
• The player left of the big blind (first to act preflop) is usually in middle position.
• Late
• The late players are last to act in the hand.
• This includes the dealer, who is always last to act.

Calculating Position

• To calculate position, first we have to calculate the dealer distance.
• The dealer distance is the distance a player is from the dealer.
• A player sitting to the immediate left of the dealer would have a distance of 0.
• Each time you move left you increment the dealer distance by 1.
• The dealer himself would have a dealer distance of (num players - 1).
• Players who are not active in the hand are skipped.
• Once we have the dealer distance we need to convert it to a normalized range.
• In a normalized range the lowest value is 0 and the highest value is 1.
• All other values are somewhere between 0 and 1.
• To convert dealer distance to a normalized range we just divide it by (num players - 1).
• Example:
• We are in a game with 4 active players.
• The dealer distances would be: 0, 1, 2, 3
• The (num players - 1) would be 3
• The normalized range would be: 0, 0.33, 0.66, 1
• Once we have a normalized range we can partition it using the following rules:
• if the normailized position is < 0.25 then the player is in early position.
• if the normailized position is ≥ 0.25 and ≤ 0.75 then the player is in middle position.
• if the normailized position is > 0.75 then the player is in late position.

Basic Strategy

• There is an inverse relationship between position and starting range.
