As electronic devices become smaller and more integrated, I bet “Faraday Cage Match” is going to be a real thing.

While not a Faraday cage, for some high-ranked tournaments (like the WC title) they are now subjected to a scan almost like at an airport before entering a sealed room.

The rules state that the playing space includes a bathroom, a place to smoke, and the halls between. There are limits to what you are allowed to have in the playing space.

You would have to close the room for sounds and light, too.

To be sure, shield it from any form of radiation (neutrons, gamma rays, etc.), too. Even getting a single bit “there’s a mate in less than 7 moves” to a player could be (possibly rarely) useful, as it would direct a player’s search for a move and/or have them commit more time looking for a move.

You can't even play online then

I mean, ethernet cables exist.

My god, did we hit the spot where people think everything is wireless ...

then you can cheat with an ethernet cable as well...
