A8o from CO, first in — fold, call or raise?
The answer
Raise
open-raise
The math: The cutoff chart opens A8o+. Ace-eight offsuit is the boundary hand.
Why
A8o is marginal and can be dominated, but only the button and blinds remain. Its ace blocks premium holdings and a raise wins the pot uncontested often enough to cross the line. Open it, then avoid overplaying a weak top pair.

Foldgive up the hand
Why not: A8o is exactly the cutoff’s offsuit-ace floor in this chart. Folding gives up a profitable steal with only three players behind.
Calllimp in
Why not: Limping from a steal seat gives up fold equity and initiative. The charted action is a 2.5bb open.

The idea behind it
Offsuit aces need late-position fold equity because they lack flush potential. In this baseline A8o is where the cutoff line begins.
