  OrigamiArtist: Apparently 19.bxa5 was preparation which seems entirely plausible and certainly a human idea; I would probably play this move too. The rest of the game also looks fairly human. A lot of people get very carried away with cheating in chess although it basically never occurs and the case against Bindrich here does seem fairly flaky.

  whiteshark: "On Saturday against Mülheim I faced Russian grandmaster Tregubov (2601). Against the former European champion I had prepared with three other players of Mülheim. The game went as planned. Three weeks earlier, in the top Swiss league, I had had exactly the same variation against GM Istratescu (2650) on the board.

Unfortunately at the time I confused the correct sequence of moves and was held to a draw. In subsequent analysis of that game I remembered Jobava-Kunin from the First Austrian Bundesliga, at which I was present and in which White won with surprising ease. So I repeated this game exactly, up to about move 20, including the exchange sacrifice bxa5, which I had already analyzed at home.

After gaining an advantage I did not play optimally, something that every chess player will see by replaying the game. Nevertheless I got a good position after the time trouble won the game. Afterwards Pavel Tregubov hesitated to shake hand looked very offended."

  cro777: According to the spectators, Bindrich went almost after every move to the toilet and used a computer program on his smart phone. After the game, the team of Pavel Tregubov made an official protest accusing Bindrich of having cheated during the game.

The Chess Evolution authors (GM Arkadij Naiditsch and GM Csaba Balogh) tried to explain what had made Pavel Tregubov think his opponent was cheating. They analysed the endgame resulting after 40...Nxe4

Bindrich (as White) demonstrated super strong play in this endgame ("maybe even super-super strong").

41. dxe4 Rd8 42. Nec4 Kg7 43. e5 Nc6 44. Kg2 Kf8 45. Kf3 Ke7 46. Ke4 Ke6 47. Nb5 Rd1 48. Na5 Re1+ 49. Kd3 Nb8 50. Nc6 Rd1+ 51. Kc2 Nxc6 52. Kxd1 Kxe5 53. Ke2 h5 54. Kf3 Nb8 55. h4 Kd5 56. g5 Kc6 57. Nd4+ Kxb7 58. Ke4 Nd7 59. Kd5 Kc8 60. Ke6 Kc7 61. Nf3 1-0

According to Naiditsch and Balogh, Bindrich usually plays fast and not very accurately, which would bring some doubts about his play. "It was just too good, almost perfect!"

  whiteshark: <Cro777>, that's plain wrong!!

<According to the spectators, Bindrich went almost after every move to the toilet and used a computer program on his smart phone. After the game, the team of Pavel Tregubov made an official protest accusing Bindrich of having cheated during the game.>

First point:

Even the arbiter/(tournament director) found nothing suspicious, as stateted in his report:

" What transpired during that game is described by <eye witness <Dieter von Häfen>>, an arbiter during the weekend matches, on the Bundesliga web site:

< During the board seven game Bindrich-Tregubov I was approached by the latter, accompanied by GM Daniel Fridman and IM Daniel Hausrath (of the host club Mühlheim). Tregubov pointed out that his opponent had been absent for quite some time and could not be found.

I walked towards the toilets and encountered Falko Bindrich returning to the board. I promised to keep an eye on Bindrich and take active measures if there were frequent protracted toilet visits.

He went to the toilet two more times, at 14:30 and 15:30 p.m., and used the flush while he was in the cabin. I decided against any immediate action.>"

The second point:

If I'm not mistaken, the official protest (of the Tregubov team) has been made only on Monday, two days later (one day after the zeroing in the Siebrecht-Bindrich game).

  tamar: <Poisonpawns: Is there a way to prove computer assistance or not?>

I don't believe you can prove anything just from the game score. The winning sequence with 48 Na5! and 50 Nc6!! is very surprising, but not out of the range of a GM.

It is even easy to persuade oneself, once one has seen the logic of the moves, that they are obvious.

That is why checking programs is so tempting. You only have to see a strong engine's approval of an idea for it to become your main focus, and to unravel its point.

It would help to know if Binder had left the board immediately before this group of moves, but still it would not be conclusive.

That is why it seems obvious players should not be allowed to carry smart phones during games.

  cro777: <whiteshark> Thanks for the feedback but that's not plain wrong! I've read Bindrich's explanation. He had a smart phone with a chess program. I aggree that Naiditsch's formulation is better: "this fact would bring some doubts about his play".

Naiditsch participated in this tournament too and knows Bindrich very well. According to him, Bindrich usually plays fast and not very accurately. It is Bindrich's super-strong, almost perfect, play in that endgame that "brings doubts" (not toilet details which I find disgusting).

Oct-28-12  Poisonpawns: After hearing multiple sides of the story and then applying old "Occam`z Razor," what do you think? Did the guy cheat or not?
Oct-29-12  thomastonk: <cro666: Naiditsch participated in this tournament too...> No, the Bundesliga matches are played in different towns. Naiditsch played the weekend in Hamburg, while Bindrich played his games in Mühlheim. Moreover, one cannot prove cheating by looking at the moves. So, if Naiditsch argued like you sketched it, this is only speculation.

  cro777: <thomastonk: So, if Naiditsch argued like you sketched it, this is only speculation.> I aggree. According to me, it "brings doubts" is correct formulation.

The problem is of effective preventive measures. Why players are allowed to have smart phones during the game, for example?

BTW, I said that Naiditsch participated in this TOURNAMENT, meaning that he was following the whole event with particular interest. That's why he and Balogh thoroughly analysed that endgame.

Oct-29-12  thomastonk: <cro777: Why players are allowed to have smart phones during the game, for example?> That's indeed the crucial question! At present one can go to the toilet, analyse the game with the smart phone, DELETE the analysis, and return to the playing hall without any fear.

About Naiditsch: he cannot be considered an independent instance, because his team is on first place, and Bindrich's team on second place according to average rating of the first 8 players, so they are direct rivals.

  whiteshark: Unsurprisingly, zeroing this game has been refused by the tournament director today.
