Combos in poker

The number of specific two-card holdings a hand name covers, six for a pair, four suited, twelve offsuit.

A hand name is shorthand for a set of actual card pairings, and the sizes differ.

  • A pocket pair such as AA has 6 combos.
  • A suited hand such as AKs has 4, one per suit.
  • An offsuit hand such as AKo has 12.

That 6 / 4 / 12 split is why offsuit hands dominate a range by weight even though they look like a minority on a range grid. Across all 169 hand names there are 1,326 combinations in total.

Combos are also what make blockers matter: holding one ace removes three of the six ace combos from your opponent's range.
