Lilov: when he plays well - he is cheating, when he plays badly - he is not cheating. Pretty poor argumentation.

Curious how does he cheat at blitz?
Not poor argumentation.

Big change in the playing strength of the same player only increase the suspect.

If somebody play all games like super GM player then maybe this player is a genius but if a person play many games like super GM player and also many games in level of fide rating 1900-2000 then something is obviously wrong.

For the question how he cheat at blitz then probably in the same way that he cheat at long time control and I would like to see if he can get good results also at bullet(1 minute for all the game when probably he has no time to get instructions from the computer because it means losing on time).

What was his rating before all of this started? In one of the video's he was described as a 2200 player.
Capital punishment would be more effective as a preventive measure if it were administered prior to the crime.

I take it you don't believe he is cheating?

I do suspect him, but I don't think my suspicion is enough to the effect of stripping him of prizes, points, etc. And Lilov's comments amount to non-falsifiable statements or syllogisms like one plays well when one cheats, one plays poorly when one does not, therefore he cheats from time to time.

It's clear to me that a good defense for him would be to only cheat part of the time. Then he can always say, "if I am cheating how do you explain that horrible game I played?"

I agree with you on his statement, it's just common sense that you will do well when you cheat but it doesn't add anything to the evidence. He probably didn't word this very well, but I think his point was the huge disparity in playing strength from one game to the next. In that, it IS indeed worthy of consideration.

Anyway, I hereby make my statement now. I refuse to participate in any tournament that he is playing in!

I think it's obvious he's cheating. I've "cheated" in online chess (but not for monetary gain, and never in tournaments) and my chess behavior was the same that we're seeing from him.

1. Playing at a godlike level for 30 moves or so and then suddenly playing like a 1500 patzer: There's a few plausible explanations for this, the most likely ones are that his computer lost the current position and he's forced to play on his own, or he is in time trouble and he doesn't have time to wait for the computer's response, or he all of a sudden remembered that he's supposed to lose this game so he blunders on purpose.

2. Too many different openings used, and he plays them very well. You don't see that very often. Even top grandmasters usually have a small set of openings they've prepared and are comfortable with. Ivanov's range of openings and his accuracy with them is too good for a 2200-2300 player.

3. Impossible for any human to make so many of Houdini's top moves in a row. No human is that accurate, not even legendary players like Fischer or Kasparov.

The problem is how does he do it.
There was a similar case here in Greece too. A complete patzer, playing all houdini's 1-2nd choices. And on top of that he refused to analyse with the opponent after the game ended every single time

There is no question in my mind that the player i am talking about was cheating, because when he was confronted he said some terrible excuses that will make every single human being laugh.

The problem is how does he do it.. Before taking action, someone has to find the trick. With current tech, and camera's at the size of a button, you need an accomplish and very little tech to do that.
