I made a video analysis of the rules of chess in the context of coding, so I had this crappy base for a chess engine.

it's easy to beat, and the difficulty scales up to a medium level, it's deceptively easy to lose against in the higher difficulties, and the highest one is only for patient people with speedy computers as it's extremely unoptimized(include a few warnings about the time it takes per move).

all-in-all it's a lightweight easy chess game, a version with graphics might come in the future but that is all I have currently.
