How to Play 83s — Eight-Three suited Preflop Strategy

83s is a first-in fold at 100bb 6-max — GTO opens it from none of the 5 positions. It only enters your range as a defend or a very-short-stack shove, not as an open-raise.

Playing 83s preflop

A fold first-in at 100bb — too weak to open from any position. Even at 5bb it stays mostly out of the first-in jamming range — it needs the right spot, not just a short stack.

In a 6-max cash game the solver folds 83s first-in everywhere — even on the Button it opens just 0% of the time. Opening it anyway is one of the most common leaks with hands in this class.

The common mistake is open-raising 83s because it 'looks playable.' First-in at 100bb it's a fold; its value comes later, as a blind defend or a short-stack shove, not as an open.
