Train A9o and every other hand until the right open is automatic.

A strong hand — open from most positions; the CO is the earliest seat it opens. As stacks get short it only gets stronger — at 5bb A9o is a jam from essentially every seat.
Position matters: from under-the-gun (LoJack) A9o opens 0% of the time, rising to 100% on the Button as fewer players are left to act behind you. The later you are, the wider you can open.
The common mistake with A9o is opening it from early position where the solver folds it. Respect the position threshold — it's an open from the CO onward, not before.
