Playing T8o preflop

Playable in late position — open from the Button onward and fold it from earlier seats. At 5bb it comes into the jamming range from 1 of the 7 seats — short stacks widen what's playable.

Position matters: from under-the-gun (LoJack) T8o opens 0% of the time, rising to 62% 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 T8o is opening it from early position where the solver folds it. Respect the position threshold — it's an open from the Button onward, not before.
