I made Jev play chess against me. How did I do it? Jev can't generate a move. It's a classification model, so it only picks from options you hand it. That turns out to be easy to work around. Any position has a fixed set of legal moves, so I generate all of them in code and let Jev choose one. Then I built a small app with a basic UI and played it. First I wanted a number, so I ran it against 600

Jev is a classification model, so it cannot generate a move itself and can only select from supplied options. The app has a basic UI.
