Professor builds better program to detect cheating in chess

3/21/2012 – Whatever some people may say, the subject is not going away anytime soon. Even the New York Times has picked it up, telling about the work of Kenneth Regan, a computer scientist who is also an International Master. He has been researching the problem for five years and was an expert witness in the French cheating scandal. Tell us what you think of his anti-cheating work.
 

By Dylan Loeb McClain

When it comes to cheating, chess might seem all but invulnerable. After all, the board and its pieces are out in the open for all to see. But an eruption of recent scandals has made it clear that cheating – fueled by powerful computer programs that play better than people do, as well as sophisticated communication technologies – is becoming a big problem for world championship chess.

Last year the French Chess Federation accused three players of colluding at the Chess Olympiad in Russia in 2010 by using coded text messages and a signaling system. The federation banned the players for five years, though the ruling is under appeal.

Of course, elite players are elite precisely because they win lots of games. When they come under suspicion, how can officials determine whether they are cheating? That is where Kenneth W. Regan comes in. An associate professor of computer science at the University at Buffalo who is also an international master at chess, Dr. Regan has been researching the problem for five years and was an expert witness in the French case – though his principal focus is the holy-grail math problem P versus NP. (P versus NP is about whether problems that have solutions that can be verified by a computer can also be solved quickly by a computer.)

Dr. Regan, 52, became interested in the chess issue during the 2006 world championship match between Vladimir Kramnik of Russia and Veselin Topalov of Bulgaria.


Ken Regan periodically communicates with us, commenting on the news stories on our web site and telling us about the work he is engaged in. His most recent message was in connection with the article A history of cheating in chess (4), on which he wrote:

Dear Frederic,

You are quite right that the "one-bit" form of cheating is the major prospective problem. It even might be conveyed unwittingly by "vibes" from a live audience – though I must report that in my game with Anatoly Lein from the 1978 US Championship, an obvious Qxg5 hxg5 Rh8# combo went unnoticed (by Lein – I saw it as soon as I played ...Ng5??) for 25 minutes despite much fidget and my awareness of people running between the analysis room and the back of the hall to see if he'd played it. Well that was a different matter being a blunder – and I'd like to see live chess watching preserved.

[Event "USA-ch"] [Site "Pasadena"] [Date "1978.??.??"] [Round "9"] [White "Lein, Anatoly"] [Black "Regan, Kenneth"] [Result "1-0"] [ECO "E14"] [WhiteElo "2505"] [BlackElo "2430"] [PlyCount "55"] [EventDate "1978.06.??"] [EventType "tourn"] [EventRounds "14"] [EventCountry "USA"] [EventCategory "10"] [Source "ChessBase"] [SourceDate "1999.07.01"] 1. c4 e6 2. Nf3 b6 3. d4 Bb7 4. e3 Nf6 5. Bd3 d5 6. O-O Bd6 7. Nc3 O-O 8. b3 Nbd7 9. cxd5 exd5 10. Bb2 a6 11. a3 c5 12. Ne2 c4 13. bxc4 dxc4 14. Bxc4 Bxf3 15. gxf3 Bxh2+ 16. Kg2 Bb8 17. Rh1 b5 18. Bb3 Re8 19. Rh3 Nf8 20. Qd3 Ne6 21. Rah1 h6 22. Qf5 Ng5 {[#]} 23. Rxh6 ({I noticed the following combo as soon as I played ...Ng5??} 23. Qxg5 hxg5 24. Rh8#) 23... gxh6 24. Rxh6 Nfh7 25. Rxh7 Nxh7 26. Bxf7+ Kf8 27. Bxe8+ Kxe8 28. Qe4+ 1-0

Of course one-move helps won't show up in (my) statistical analyses. Nevertheless, there have been regretfully numerous cases where cheating on essentially every move of every game turns out to be the issue, and this does show up.

For the record, Rybka 3 to fixed reported depth 13 sees 20.g4! in Kasparov-Anand from several moves away, per my Arena-scripted Single-PV analysis from June 2009 which is pasted after my name. So does the 50-PV analysis used for my full-bore statistical modeling. This analysis underlies my published scientific papers last year with Guy Haworth and Bartlomiej Macieja.

Yours sincerely,
Dr. Kenneth W. Regan


Articles on cheating over the years

A history of cheating in chess (4)
28.02.2012 – Las Palmas 1996: Garry Kasparov is agonizing over his 20th move against Vishy Anand. He calculates and calculates but cannot make a very tempting pawn push work. Immediately after the game he discovers, from his helpers, that it would have won the ultimately drawn position. The point that became clear to him: a single bit of information, given at the top level in chess, can decide a game.
A history of cheating in chess (3)
18.12.2011 – In January 1999 the main topic of conversation amongst top players like Kasparov, Anand and others: who was the mysterious German chess amateur, rated below 2000, who had won a strong Open ahead of GMs and IMs, with wonderfully courageous attacking chess and a 2630 performance? How had he done it? Turns out it was with unconventional methods, as subsequent investigation uncovered.
Early chess cheating story by Martin Gardner
18.10.2011 – American writer Martin Gardner anticipated current cheating woes in chess with his short story Nora Says 'Check'. In it a world champion called Sierpinsky alleviates his chess boredom by guiding a not very bright waitress named Nora to chess fame with the help of a confederate and some electrical trickery. You should not miss this visionary jewel of a tale, written in 1948!
A history of cheating in chess (2)
04.10.2011 – Coaching players during the game is probably the most widespread form of cheating (rivaled only perhaps by bribery and the throwing of games). Although this practice began long before the advent of chess playing machines, computers have added a new and dramatic dimension to this method of cheating in chess. You will never guess: who were the pioneers of cheating with computers?
A history of cheating in chess (1)
29.09.2011 – Hardly a month goes by without some report of cheating in international chess tournaments. The problem has become acute, but it is not new. In 2001 Frederic Friedel contributed a paper to the book "Advances in Computer Chess 9". It traces the many forms of illicit manipulations in chess and, a decade later, appears disconcertingly topical and up-to-date. We reproduce the paper in five parts.
Feller's interview, and a solution to the cheating scandal

Anti-cheating: the fifteen minute debate continues
29.06.2011 – Our recent reply to stern criticism leveled against us in the Dutch magazine New in Chess resulted, unsurprisingly, in a large number of letters from our readers, many quite effusive.

Now we can publish your letters.

Big illustrated report.
Anti-cheating: the fifteen minute broadcast delay
13.05.2011 – For five years we have been trying to get FIDE to implement a 15-minute delay in the Internet broadcast of important games – to make organised cheating harder.

Damn – and we thought it was such a good idea! What is your opinion?
Cheating scandal: Opinions, concerns and revelations
06.04.2011 – In a series of interviews, Robert Fontaine from Europe Echecs, culled the opinions of the players, to get a clearer idea on how players both French and foreign viewed the cheating scandal.

Open letter.

23.01.2011 – Cunning, gamesmanship, skulduggery, bluff, trickery, foxiness, dishonesty and cheating are just some of the terms that may be applied to a set of episodes related by the Editor of Chess Notes.
