A first attempt at a pico8 chess engine.
Move generation is currently unoptimised so AI is fairly slow and doesn't have a great depth search.

-- Controls --
Use arrow keys to select a piece
Use z to confirm
Use x to disable AI

Oooh, we could try an Pico Chess AI contest!

Not too shabby! The music is Pachabels canon, yeah? AI isn't too hard to trick, but it isn't stupid either. I look forward to the refinement of this cart!

I played twice and got beat both times, I suck at chess but star for this excellent cart!

The colors of the board are reversed :)

why?

@Nizart the engine isn't perfect, likely a bug with move generation

Owned.

Second game though. The first attempt I had a major advantage but then both me and the ai screwed up so it was a near victory. This works pretty well, but it occasionally seems to give the player the ability to move the ai pieces. In the one above, I noticed the ai doesn't know how to break defenses, so just slowly moving forward with an unyielding wall where nothing is unprotected totally destroys it.

@kimiyoribaka if you press x it disables the ai and allows you to control the ai

I'm not very good at chess so losing this game doesn't surprise me, but what's remarkable is how it brought me down. Too fast.
