On an organizational level I think ANY national-level bridge body is going to be rather poorly equipped to actually
catch cheaters. ACBL, EBU, ZimmermanBF, whatever. Monitors at tables aren't going to be able to see anything ever, and trying to staff world class players on a full time basis isn't going to work because they aren't taking a massive pay and enjoyment cut to do that instead of playing bridge.
I think the only thing it's reasonable to ask of them is to put procedures in place to make it easy to analyze plays after the fact to catch people more effectively.
Those things pretty much include:
- as much video as possible, of suitable quality
- hand records in as much detail as possible ideally including complete play records
- duplicated boards wherever possible for maximum comparison purposes -- I'm aware there are potential security issues with having the same boards in play but those really really don't seem that hard to cover
- making as much of the above publicly available as humanly possible
64 video cameras that can record like 3 hours at a time and store data are what, I'm going to guess generously $150 each? And that covers the entire round of 64 of a KO event, or 128 pairs worth of a national pair game. Then you just need enough data storage and a Youtube account. And then the play records. I know they were testing the machines that deal the cards out and record everything -- which helps with duplicated boards as well.
Do all that, put it all out there (as a bonus: fans can review stuff and learn more), and then really the only think you have to worry deeply about is the electronic shoe vibrators or whatever. Everything else, the good news is if they're trying to communicate with partner during the hand, it'll be audible or visible, and with video and audio evidence, if their partner can see it, the eye and ear in the sky will too. They'll get caught.
