If you want it, i made a digitally playable Mind Chess, so you're less dependent on the honor system https://jasperblank.com/mind-chess/

I really like such simple games, to help Analise it can be fun to look at the whole game at once, if you want see that i made it a graph at https://github.com/JasperBlank/1DChess

I really liked seeing the graph you made of the game. It gives such a different look to a game. Since someone recently uploaded 1D chess here, i decided to make a graph like yours for that game too. https://github.com/JasperBlank/1DChess

Your company is quite interesting for me, i made a demo for this project, visible at https://jasperblank.com/hearo/
