Poker

Poker ranges by position

Poker ranges by position assign different starting-hand ranges based on a player's seat relative to the action order, with later positions playing wider ranges than earlier positions.

Applies to
Preflop strategy in Texas hold 'em and Omaha hold 'em, where seating order affects which hands are entered profitably.2
Core principle
Acting later provides more information about prior action, allowing a wider profitable range.1
No fixed numbers
The concept is a qualitative framework, not a universal numeric rule.2

Key points

  • Early position requires stronger hands because fewer players have acted; late position can include more marginal holdings.12
  • Position-based ranges are used as a preflop decision-making framework, not a fixed set of rules.2
  • The same hand may be playable from late position but unprofitable from early position.

Where this term is used

Not the same as

  • Out of position poker — out of position poker is about the disadvantage of acting first, not about assigning ranges to seats
