How to play A8s
Playing it before the flop
Open it from cutoff onward. A8s wins 61.9% against a random hand, and much of its real value is not in that number, it makes the highest possible flush, which is worth far more than an ordinary one.
Facing a 3-bet
These are the natural bluff 3-bets. Holding an ace removes three of the six ace combinations from the opponent's premium range, so the hand does double work: it blocks their continuing hands and it flops the nut flush draw often enough to keep barrelling.
After the flop
Be honest about which flops matter. With a small kicker, A8s making top pair is a modest hand that should not play a big pot. Making the nut flush draw is the opposite, that is a hand that can raise, semi-bluff and get stacks in.
