How do you play ace five suited?

Open it from any seat, and use it as a re-raise bluff against opens, since holding an ace makes it less likely your opponent has aces or ace king. It also plays better than the other small suited aces because the five can make a wheel straight, giving you a second way to win a big pot beyond the flush. When called, it has clean equity with the nut flush draw and the wheel draw.

This hand opens for a raise from every position, including under the gun.

Common mistake: Treating it as a strong made hand. Its value is in the flush and straight draws and the bluff potential, not in making a weak pair of aces and calling down.

Quick tip: The ace blocks aces and ace king, which is exactly why it makes a good re-raise bluff. The wheel is the bonus.
