yeah in analog chess you could just check if the other pawns near it collide in trajectories when doing the double move and if they do then en passant is in effect.
Interesting. Did something similar with a self hosted version of geoguesser with my friends. We set it up right near our school. We have multiple routes walking home and the amount of precision we could get was insane. One of my friends was able to get only a few meters off from the original position almost instantly.
I found it more fun than Back of Your hand just because I frankly don't remember too many streets but can recognize the overall area from walks I go on.
Seems like just a coincidence. Though with how Russia likes to control the media I am surprised that they didn't change the colors to stop exactly what is happening now.
