Straight Flush (any five consecutive cards all in one suit, except those in a. above) (1 point) c. Four of a Kind (e.g., four Aces – or any other kind – and any other card) (1 point) d. Full House (3 of one kind and 2 of another, e.g., 3 Aces & 2 Kings) (1 point) e. Straight (any 5 consecutive cards, but can be from 2 or more suits) (1 point) f. Flush (any 5 cards from the same suit, but not in consecutive order) (1 point) g. Two Pair (e.g., 2 Aces & 2 Kings – or any other two different kinds, and any other card not an Ace or a King – or not the same as the kinds with 2 each) (1 point) h.
