How to Play K8o — King-Eight offsuit Preflop Strategy

GTO opens K8o first-in from 2 of the 5 positions in 6-max cash — from the Button onward. Earlier than that, it folds. In numbers: the button opens it 68% of the time and the lojack 0%; at 15bb it is a first-in shove from 1 of 7 seats.

Playing K8o 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 3 of the 7 seats — short stacks widen what's playable.

Position matters: from under-the-gun (LoJack) K8o opens 0% of the time, rising to 68% 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 K8o 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.
