Now comes the critical part. After six rounds of play the Russian news site WhyChess noticed "something fishy at the Botvinnik Open". Takme a look at the the following segment of the table – do you notice something strange?

You probably spotted it: a certain Sergey Klimentiev, rated 1698, seemed to be doing rather well. A big performance jump by some super-talented youngster? That would be a reasonable explanation.

But no, Klimentiev was born in 1969, he is 42 years old, and his rating has remained stable between 1678 and 1711 over the past several years. In this event he was suddenly playing at a 2200 level, having beaten a series of FIDE Master level players, crushed IM Alexsej Lanin and drawn with IM Ivan Rozum. But, as the Russian Chess Federation web site writes, "players and organisers claim that after a game Klimentiev is unable to show or recall the moves he has played." Apparently he did not even know the names of the openings he played...
We took a look at a random game by Klimentiev – actually the first one. It is fairly easy to chess such games with an engine: in Fritz 12 (or earlier versions) you simply load the game and use a function called Blunder Check:
When you click "Blunder Check" you get the following dialog:
Note that we have given the program ten seconds per move, asked it to annotate only the black moves and store the evaluations with the game notation. We set the threshold to 0, i.e. Fritz should tell us whenever it would have played another move, however small the evaluation difference that led to this decision.
After clicking OK is it advisable to take a short coffee break – the procedure is going to take a number of minutes to complete. This is what we got:
In the above game Fritz deviates from the text moves by Black only six times, and for reasons that are always worth less than 1/100th of a pawn. Using a different engine – Rybka, Hiarcs, Junior, which you can do using the same interface – will give you closer or worse correlation. If you want to do your own experiments here is a PGN file with all nine games played by Sergey Klimentiev at the Botvinnik Memorial Open.
Now all of the above does not in any way represent irrefutable proof that an engine was used. We should mention that we have done similar experiments with the games of José Raúl Capablanca and discovered that the third World Champion occasionally used computer assistance. Just kidding, of course – but the fact is that sometimes very strong players will play an entire game where most of the moves meet will the full approval of chess engines.
But let us return to our hero: we do not know exactly what happened after game six, but surfing the Russian chess blogs seems to reveal that the authorities, suspicious of Klimentiev's extraordinary performance, did not allow him to bring along his briefcase or use the pen he had used that far. In addition he had to play on-stage, where spectator access was restricted. This was his next effort:
Polivanov,Anatoliy (2435) - Klimentiev,Sergey (1698) [C57]
M.Botvinnik Memorial 2011 St. Petersburg (7), 18.08.2011
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.Nxf7 Bg4??
The counter-attack on the queen doesn't work: 7.Nxd8 Bxd1 8.Bxd5 Rxd8 9.Bxc6+ bxc6 10.Kxd1 and Black is simply a piece and pawn down. 10...Bc5 11.Ke2 0-0 12.f3 e4 13.Nc3 exf3+ 14.gxf3 Rde8+ 15.Ne4 Re5 16.d3 Be7 17.Be3 c5 18.Rag1 Rf6 19.Rg3 Bd6 20.Nxd6 cxd6 21.Rhg1 g6 22.f4 Re8 23.Kf3 a6 24.Rg5 Rf7 25.h4 Rfe7 26.Bd2 Kf7 27.h5 Re2 28.hxg6+ hxg6 29.R1g2 Rxg2 30.Rxg2 Re6 31.Rh2 Kg8 32.Bc3 d5 33.Be5 Kf7 34.Rh7+ Kg8 35.Rc7 Rb6 36.Rxc5 Rxb2 1-0.
Klimentiev lost all three remaining games, as you can see in the following extract from the final tables:
97 | FM Duzhakov, Ilya | 4.0 | RUS | 2338 | 2259 | |||||||||
98 | Klimentiev, Sergey | 4.0 | RUS | 1698 | 2005 | |||||||||
99 | Kobzar, Alexandr | 4.0 | UKR | 2184 | 2303 |
We leave you – and the organisers, and FIDE – to decide how this and similar cases should be handled. It seems like the problem of cheating simply will not go away and is becoming harder to ignore.
Erik Kaukonen of Chicago, USA, informs us that apart from the Botvinnik Open,
Klimentiev had two
fantastic results from his two other most recently completed tournaments:
White Nights 2011 Open and Summer on Petrograd Side 2011. In White Nights, he
entered the tournament rated 1698, and scored 6/9 for a 10th place finish, even
though seven out of nine opponents were rated more than 400 points above him.
His K score= 77.55 which is far and away the largest increase in the field.
In Petrograd Side 2011, he ended up tying for first with 7.0/9 even though 8
out of 9 opponents were rated more than 400 points above him. Again he had a
K score of 93.60- by far the greatest increase. In just two tournaments he increased
his Elo by 171.15 points and scored a remarkable 13.0/18 against 15 opponents
rated more than 400 points above him. "Stands out like a sore thumb IMO,
Erik writes. "More evidence is needed to prove guilt but I wonder if he
had his trusty pen and briefcase along for those tournaments?"
