How to Play 65s — Six-Five suited Preflop Strategy

65s is a premium starting hand: GTO opens it first-in from all 5 positions in a 6-max cash game, and it stays in the shoving range down to the shortest stacks. It's a raise-or-shove hand — never a fold first-in. In numbers: the button opens it 100% of the time and the lojack 56%; at 15bb it is a first-in shove from 1 of 7 seats.

Playing 65s preflop

A premium hand — open it first-in from every position. 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) 65s opens 56% 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 65s is playing it too passively — slow-playing or flat-calling when the solver simply raises it for value from every seat. Open it, and be ready to get the money in.
