Cheating In Chess

Compared to other sports cheating in chess are relatively few and almost negligible among professional players –cheating to win that is- until the advent of computer programs and wireless technology.

Cheating to lose is however another matter. The most popular tournament format nowadays is the Swiss System where it is possible to have an acceptable winner even if the participants number in the hundreds as players with the same score are pitted against each other .

Cheating occurs usually in the last two or most often last round where games are fixed and money exchanged in return for throwing the match. It usually happens in the top 2 or 3 boards and the arbiters are hopeless in preventing it. This practice is common in local and international matches where the players know each other very well .

There is a grey area in the game known as “grandmaster draws ‘where some form of cheating occurs. During the 70s when the Soviet Union was the predominant power in chess, they usually drew their games and ganged up on the rest. It was only Bobby Fischer who by his enormous will to win and incomparable talent demolished the Russians and became a legend up to this day.


Wireless Last July, in the World Open in Philadelphia, a scandal occurred when two players were accused of cheating using wireless technology. It seems that a player who was one of the lowest ranked in the main tournament was confronted by the tournament director for winning a string of wins against much stronger players.

He retired to the bathroom where he spent 45 minutes and after that he lost all his remaining games.

GM Larry Christiansen later analyzed one of his games by using the computer program Shredder. The last 25 moves matched those of the computer.

The other player, later identified as Steve Rosenberg , was found to be using a wireless receiver known as a “ phonito “ and was disqualified.

Yoghurt The most comical of cheating allegations occurred during the Match of the Century in 1972 when Boris Spassky`s second Efim Geller accused Bobby Fischer`s camp of disturbing Spassky`s concentration. The Icelandic police later swept the tournament hall of electronic devices and found 2 dead flies in the lighting system.

Another comical accusation of cheating was during the World Championship in Baguio City when Victor Korchnoi accused Anatoly Karpov of cheating by drinking yoghurt in several colors suggesting that these were signals

Also both camps employed hypnotists to”bother” each other with Karpov employing a certain Dr. Zukhar and Korchnoi hiring a member of a local cult who was accused of murder.

Deep Blue An allegation by Garry Kasparov that he was cheated by IBM in his loss to the computer program Deep Blue in 1997 in Philadelphia shocked the entire chess world who could not believe that IBM would do such a thing .

Kasparov claims that there was human interference in the 2nd game won by Deep Blue when the machine refused to move to a position that had a decisive short-term advantage, showing a very human sense of danger.

Deep Blue was able calculate 2 billion positions per second and was retired after the match.

During the inter-collegiate chess championship in the US several years ago, one college, played a match against the University of chicago who had a pinoy player in their line-up, Angelo Young in board one, who is a strong player. His opponent was the late grandmaster ,Alexander Wocjiewicz , who was studying in that college in only one subject and enrolled just for chess tournaments . I don’t know if you can call this cheating. (courtesy of CEPCA)

    Nice to recall history, but please do so correctly. In the Korchnoi incidents you mentioned, Kortchnoi did indeed object to the presence of one Dr Zukhar (? on the spelling). He was with the Russian party supporting Karpov and his role has never been clarified by anyone. The upshot of this was that Dr Zukhar wasn't allowed to sit within a certain distance of Kortchnoi while play was in progress. The cult members you mentioned were never hired by Kortchnoi, they were members of the Ananda Marga sect and had befriended Kortchnoi during the match and suggested that they could nullify Zukhar's hypnotic stare by a counter stare on him, this led to some unusual scenes with one man staring intently at another whilst two others stared intently at him :) This was after the Russian party had objected to Kortchnoi's use of the Swiss flag, remember Kortchnoi had defected from USSR only 1.5-2 yrs before and the Russians argued that he hadn't been a member of the Swiss chess community long enough to qualify as a resident or such. Several petty protests had already occurred during the match, Kortchnoi and several of his party felt that they were getting shortshrift in these matters, that the organisers were pro-Russian. So in a moment of brevity, they decided to protest that Karpov was having yoghurt delivered to him without ever requesting it, and that it could be some sort of code, in that the colour of the yoghurt indicated to Karpov as to what or how he should play. Unfortunately, the protest was dealt with officially and has become part of the folklore of World Championship chess.

    Perhaps a more interesting incident would be when Kortchnoi and another World Champion played each other and they ended up kicking each other under the table !! The only recourse for the organisers was to have a table with a divider brought in so that the match could continue.

    A worthy addition to this article would be Topalov's accusations against Kramnik in their championship match.
