What cellphone was he using? And what chess software? I'm just curious

To his credit, Natsidis acted decently once he had been caught by admitting and apologising. He could possibly have gotten away with it by not showing them the chess application with the position from the game.
This is very unlike the French case when Feller has acted very badly since the allegations came to light by throwing accusations back at the French federation and vehemently maintaining his innocence despite overwhelming evidence against him (acting like most sports cheats).
I agree with Arne Moll that it is an overrated problem. Cheating seems to provoke an emotive response in people leading to daily mailesque arguments, as can be seen by some of the comments above ('ban for life' etc) which are daft.

I very much doubt Nadsidis did this only in the last game and only during this event.
I remember him in the Mariembad tournament http://www.czechtour.net/history/2007-2008/marienbad/
after having lost the first round, he asked his second round opponent, through the arbiter (!!!) to draw his game without playing (he wasn't even present in the playing hall!). The arbiter insisted justifying this with the fact that if he drew he would have preserved his chances to make an IM norm.
His opponent refused to agree to a draw without playing and Nadsidis withdrew from the event.
These people seriously damage the game. Hope he stays away from Chess (and law, possibly) in the future.

Official tournament rules will have to adapt to growing popularity of smart phones. A good start would be mandatory registration: when they're signing up for a tournament, players should formally acknowledge the fact that they will be carrying a smart phone during gameplay, and also sign a guarantee that they do not posses any chess software on their phones. All players who would carry an unregistered smart phone during gameplay would get disqualified upon the discovery of the fact, as well as those with chess software on their phones.

This precaution would basically amount to a single signature at the start of the tournament. Perhaps it does not prevent systematic cheating - one can always simply not register the phone - but it does offer an additional discouragement. Formal rules strengthen the feeling of cheating, of doing something harmful. If a player binds himself to clean play with a signature, he will be much less prone to occasional cheating.

In every case, FIDE will have to react with new rules regarding open tournaments.

It really beats me why would anyone do this. One cannot possibly keep cheating to reach any considerable heights in chess hierarchy, and stealing a few additional points in a tournament or two seems just utterly pointless. Given that Natsidis admitted his deeds and expressed regret, it would be really interesting to hear his own thoughts on the matter.

Maybe just having to sign in and out of the tournament hall every time you go to the bathroom would deter some cheaters.

If you are cheating in a last round, when you already has enough points for a norm, then you probably also have cheated the rounds before...

Isn't Natsidis actually a Greek surname?

The majority of people being caught cheating have been those cheating in a really crude manner . IMHO The possibility of cheating has take n alot of the shine out of chess in these sort of tournaments .
I think slow play chess is on the way out because of it - a solution would be to stick to rapidplay games players not allowed to leave the table during the game

If you look at the picture of Natsidis, you can actually see a bulge in his left pocket.

I suppose that once a cheater has been exposed, then they are not going to cheat again since they know that their future games are going to be under scrutiny.A lengthy ban will be over the top but something like a 1 year seems o.k.I think that these cases of people cheating are very rear, the person would have had to be away from the board for many occasions.I have played in many chess tournaments and not once have I had to do a bowel motion, urinating is far more common.The total time that a person could be out of the playing hall should be limited and also the number of occasions.

"Three times, I made a move and it took 8-10 minutes for him to show up at the board. "

I tend to use the bathroom quite a lot (more than 3 times probably) sometimes when I am nervous or something during games. Does that mean I shall be suspected for cheating?

It have to be more creative than a keychain or stress ball. The more productrelated the better. You want people to remember and talk about you positively!.
The biggest waste of time when working out at the gym or at home, thinking you will lose the pounds and inches, is [url=http://www.coachnitijou.com/]コーチ アウトレット[/url] コーチ 財布 http://www.coachnitijou.com/ only core training. The midsection or abdominal region seems to collect fat quicker than any other part of the body, especially in men. This seems to be evident in the amount of men [url=http://www.coachsekai.com/]コーチ アウトレット[/url] コーチ 財布 http://www.coachsekai.com/ sporting the beer belly look and their determination in getting rid of [url=http://www.begincoach.com/]コーチ 財布[/url] コーチ バッグ http://www.begincoach.com/ that "spare tire." They are so desperate to get rid of their ever growing abdomen that they work out only on those muscles without realizing that it is really doing nothing but making them work extra hard and seeing no results..
