A fun gag, however I'm not sure if the game actually follows standard chess moves as I was unable to move certain pieces when the game claimed there were no legal moves even when there was no check or anything like that... Chess pros can actually play the game in their head just thinking about the coordinates, this game actually could have some use as training materia as a stepping stone for that ability but this requires the game actually following proper chess logic. Also if there was the ability to check each pieces coordinates it would help as sometimes moving the pieces I didn't even know which piece was moved and to what square... which I guess was the joke but still.
