To Vigo or not to Vigo? That is the question.

Is this a deception? I personally saw that Vitalik was playing instead of Vigo. If not, then you can't speak with such certainty...
Well, if Maretti comes to your place and plays all the games under your nickname, I wouldn't be against it, but the question arises: does he even need it? Where's the logic in that? Why waste your time on someone else, even if you've been friends since childhood?
Besides, playing a few turns is one thing, and playing an entire game is another.

But Vigo himself confirmed that "several" turns were played for him (although it's hard to believe). This is a fact. Formally, he violated the rules. Formally...
But no one will ban him for a couple of turns, you understand that. And AK (as well as most of the forum) is confident that not just a few turns were played for Vigo, but at least several games. This is where a psychological portrait of the person is needed: could he do it? What do we see in Vigo? He's unprincipled, a cheat, irresponsible, and a liar. By comparing these and many other facts, AK comes to the conclusion that Vigo cheated 99.9% of the time. There will never be 100%, not unless Vigo himself confirms it. But 99.9% is already enough; a DNA test isn't more accurate.
