Daniel Naroditsky[1] said at the St Louis chess club specifically it would be pretty easy to cheat OTB no matter what searches they do. He said there is a balcony which the players have access to when they walk away from the board which has a clear view of the car park and you could have an assistant signal from there at crucial moments. He also cited a case of a player who was definitely cheating OTB[2] and was never caught and where no mechanism was ever found.

It really seems to me that everyone is overthinking this. Hans has admitted to cheating and just says he didn't cheat here. The idea we should give him the benefit of the doubt seems really odd. It doesn't really matter to me whether he cheated in this specific tournament - he shouldn't have a place in the chess world.

Word, I hear ya, a cheater is always gonna be a cheater. … But, honestly, we are going through a strange transition in chess. I’m not very familiar with online chess, so I take that sort of cheating lightly. Was surprised that online games can effect OTB ratings. I’m guessing FIDE, USCF , and other orgs will start separating online vs. OTB ratings as a result of this friction.

the TSA airport x-ray scanners, would they do a nice job of finding devices internal or external?

It seems at a minimum they could go through the same level of security as it takes to board a plane: remove shoes, back-scatter x-ray, etc.
