If you want to play a person (which was kinda the original point, the bot was really only put in there so I could test better) feel free to email me and we can sort out a time I'm Scott@[myusername].com.

Good question. It was originally designed so you could play against other humans each with their own claude instance helping them evaluate possible moves so...I won, but my son is five so take that win for what it is worth :)

The chess engine sits on the server keeps all moves legal but Claude will definitely hallucinate some terrible options for you, especially if you're using Haiku. If I had to guess I would say Opus seems to play around at 1200-level game.

It is setup so you could give Claude access to a much better engine to choose moves from though, I just...haven't added that yet :(
