Well he has got some right to be at least annoyed and must be under a lot of stress. It's a rather serious accusation after all.

There is definitely a long term worry than in a few years (or even now really) it will be essentially trivial for a vaguely determined person to cheat pretty invisibly. Not precise moves or something but a signal as to the nature of the position or some such.

Objectively much more worrying than smart phone cheating. A time delay on live transmissions would be a very good idea.

Well, I don't know my compatriot, Mr Ivanov, in person, but we live in a small country and I know a thing or two about it.
First of all, he is not a programmer, but a student in the pedagogical institute of his native town, Blagoevgrad (situated one hundred kilometres south of Sofia). And he is also a member of the Blagoevgrad's chess club "Victory".
Although denying the possibility of cheating, Victory's chairman Marin Atanasov didn't include Mr Ivanov in the Victory's team for the National Team Championchip last year, even on the sixth board.
I, for one, going through all the Zadar games of Mr Ivanov with an engine, think that there was cheating happened. But, as long as it's not proved, I wouldn't state it as a fact.
What amazed me is that Mr Ivanov never wanted to show in public (say, through Internet in these modern times - Facebook, chess forums and alike) to defend himself with analyses of the games or whatever. All we heard from Mr Ivanov were insults and very, very bad behaviour in some of the Bulgarian chess forums. Of course, I can post links with some of his offensive phrases here, but the language he used is not appropriate for such a forum as Chess Publishing. In fact, these words of his were written in Bulgarian slang with latin letters. And it's beyond doubt that are Mr Ivanov's ones.
One of our Bulgarian IM's (now not competing in tournaments) even wanted to set a match between the two of them, while using electronic sets for a broadcast interception (or whatever they call it), but soon rejected the possibility because of Mr Ivanov's bad manners.
May I say that sometimes I feel too old when looking at some young men's behaviour?! Some questions arise - such as.. Is it normal now, in these modern times, for some young men to behave like this? Or is it just an exception - like this one, but that we meet very often nowadays?!

It is tougher to take the tournament organizer seriously, because he broadcasted the moves without a 15 minute delay.

By broadcasting the moves without the common sense 15 minute delay, the T.O. is announcing to all that he does not care much about cheating and the security steps that make cheating harder. (The delay is a good security measure that Frederic Friedel has been urging for many years.)

The person of interest, Borislav Ivanov, has done nothing wrong, until someone can prove otherwise.

The overall tone of the first chessbase.com article (newsid=8751) was improperly accusatory, despite their second article (newsid=8760) that tried to backpedal on tone.
. .

Lilov's case (saw it on chessbase) looks pretty persuasive...in particular the situation where Borislav blunders a piece to a back rank trick and later on plays brilliantly in the same tourney.  Seeing the sacrifice of a bishop as Black against a 2600+ player for the Queen penetration...I mean it's tough to give him the benefit of the doubt particularly as it seems unlikely someone of 2100 to 2200 would consistently be choosing moves the computer either likes or thinks are ok. 

How sad it is that there has been enough cheating to cause a pall of doubt to be cast over every outstanding performance by an unknown player.

I think though that a statistical analysis would reveal that the chance of there not being an occasional excellent performance of this kind, without cheating, is quite low. The weather is not always normal, you know. And it's a funny thing, but no one notices when a 2277 has a really crappy tournament.

It's not a "cheating scandal", it's a "certain suspicion". They searched him and found nothing amiss so he is in the clear for now. It may depress you all you want, but I don't think Ivanov should be called a cheater unless/until something is proven.
