I don't know how you worked this out, but it looks fantastic! My mind can't stop thinking about how to make these guys work; both against other opponents and against themselves! I'm not much of a chess player, but you have no idea how giddy I felt reading about the different movement patterns in "Rank and File" ;-)
Also, when is "Root: The King's Gambit Animated Series" coming out? I need to see more of this story and artwork! ;-)
