It has nothing to do with majority knows best, it was breaking the rules, therefore cheating. Whether the rules were correct is another matter entirely.
Exactly this, about the Armstrong thing.
Actually it was less clear about Ivanov, there was some debate about whether computer input could be considered as "advice" or "information" as per FIDE rules (but you can guess my point on that). The debate was not whether computer help should be allowed, but whether it was allowed under present FIDE rules (in which case, the rules would need changing, but there would have been no infraction from Ivanov).
There are a few points in this story that don't add up:
1. In the room there was a sweep with metal detectors before the shoe thing. Why didn't the metal detectors pick up the phone!?
2. If it would be a phone, the strongest engine would be Stockfisch on Droidfish right? Is Stockfisch on Android strong enhough to beat a GM?
3. The arbiter said Borislav was to be disqualified, but still Borislav turns up for the next round??
1. Look at most metal detectors: they don't usually go all the way to the floor. They probably aren't using Presidential Event level security.
2. He's a programmer, it is likely he has something of his own, rigged to understand tapping and respond with vibration patterns. Dlugy mentions how he taps around feverishly with his feet sometimes.
3. Organizers may have been in on it. It's Bulgaria. Danilov.
The controversy over charges is disappointing but about right, without a criminal record he would get a probation deal for first offense. But there is no need for a warrant to search his feet: organizers are permitted to institute any necessary rules, and by entering their event you are agreeing to them.
If Ivanov's unusual gait and extra large shoes had been mentioned in earlier reports, even a child could figure out his method.
I think it's likely. I can't believe they allowed him to continue playing. Before the next round I seriously would have "tripped" and accidentally stepped on his foot.
"Oops. Good luck next round man."
