Combos refer to the number of different possible card combinations that make up a starting hand. There are 52 cards in a deck, 13 of each suit, and 4 of each rank. This means there are:
- 16 possible hand combinations of every unpaired hand.
- 12 hand combinations of each unpaired offsuit hand.
- 4 hand combinations of each suited hand
- 6 possible combinations of each pocket pair.
For example, in Hold’em, there are six possible combos of pocket aces (A♦A♣, A♥A♠, A♦A♥, A♦A♠, A♥A♣, and A♣A♠) and four combos of 7-6 suited ( 7♦6♦,7♣6♣,7♥6♥, 7♠6♠).
