People can still cheat with some hidden hardware I guess [0]. A full body inspection of each player would be required as well.

Most of the _plausible_ systems involve a one-way link, where an observer is running the engine and supplying information to the player through some system that is perceptible to the player and nobody else. Forcing the player to pass information about the board state _outward_ certainly doesn't make cheating impossible, but it makes it a whole lot harder - input devices that can't be observed are much more difficult.

Not if it’s tied to the live game state available on any number of websites or broadcasts. And the harder the game gets, the more delay you’d need to prevent timely feedback in such a system, as thinking about moves for considerable periods of time is commonplace.

I personally think the stakes are plenty high enough that people would try any convoluted mechanisms that they could sneak past security.

Maybe Neimann’s a cyborg - more machine than man now.

But yeah, no spectators and a delay should be pretty effective OTB.

Maybe that one way link is as simple as high frequency sound, that he's trained himself to hear which everyone else ignores. Simple on/off modulation, or maybe two freq modulation...

The amount of data required to communicate a chess move is very little.
