Ace (poker)
The highest or lowest card in the deck. If the cards are arranged
in order, the ace either starts this sequence: A-2-3-4-5-6-7-8-9-T-J-Q-K;
or finishes this one: 2-3-4-5-6-7-8-9-T-J-Q-K-A. In high poker,
the ace is the highest card in a hand, with one exception: when
it is part of a 5-high straight, that is, in this hand: A-2-3-4-5,
of mixed suits.
