This made me laugh out loud. But yeah! I was so fixated on making a butt plug-mediated communications protocol that I overlooked a far low-tech, but more effective method. And if detection is a danger, the gestures used can be changed up and agreed upon before the match. One match might have massaging the forehead as the signal, another match could have scratching behind the right ear.

And my theory about the butt plug being able to be smuggled through a metal detector is not based in a proven fact, but rather the assertion that if you could get one through a metal detector, which may or may not be possible, there would be no other checks in place to prevent a player from entering a hall with one.

I see. So we're both coming from the assumption of "if it were possible, how might it go?"

More complex cheaters (who do not use an accomplice) have in the past gone to the washroom to find a stashed chess computer, plug in the position, see what the computer thinks, and come back.

Isn't this easy to catch though? Inspect the restrooms players have access to and periodically inspect them when no one's using it. Of course, this doesn't stop a determined cheater stashing a small device inside a pack of wet wipes, for example. Heck, if I were in that situation, I'd probably just stash a smartphone inside a supposed pack of wet wipes. It's boring, not as sensational as a butt plug for sure, but if it works, it works!

Just responding to the last one, it was that easy and that's why nowadays the entire premises is swept for any potential aids before the tournament (I.e. the day before, go through every space and make sure that nothing is hidden), the player bathrooms are separate from everyone else's so that no one can sneak in to place something there without going through player screening, and everything you carry into the match is thoroughly inspected to ensure it doesn't contain a chess computer (to the point where they will check people's lipstick).

The reason the butt plug theory gained so much traction is that with the current security, there's only one check to stop it (the metal detector), the cheating method itself is theoretically sound, and its attention grabbing enough as a concept.

Much as with anything competitive, it's an arms race to gain a leg up before the advantage is neutralized so I'm sure that someday we will see a genuine case of butt plug cheating or security measures put in place to specifically prevent anally assisted gameplay
