One specific pair of hole cards, such as A♠K♥, out of the 1,326 possible starting hands.

Last updated

What it means
A hand class such as AK covers several specific card pairs. Each specific pair is a combo.
How it is calculated
Pairs have 6 combos, suited hands 4 and offsuit hands 12. Across all 169 classes that is 1,326 combos.
Worked example
AK has 16 combos: 4 suited and 12 offsuit. KK has only 6, so a range of AK and KK is weighted 16 to 6 toward AK.
Why it matters
Counting combos is how ranges are weighted properly. A class with more combos shows up more often.
