@mona@cybre.space I'm curious if you're familiar with Arimaa at all? I haven't played it, but it was talked up on the BGG community for a while. IIRC it was explicitly developed as a game that would use the classic set of chess pieces but be unusually difficult for AI players to master relative to human ones. I have no clue if it's ever caught on, let alone spawned an online play community, though...
