A history of cheating in chess (4)

2/28/2012 – 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.

Cheating in Chess

By Frederic Friedel

This paper appeared as a contribution to the book "Advances in Computer Games 9", edited by Professors H. J. van den Herik, University Maastricht, and B. Monien, University of Paderborn. It was published by the Universiteit Maastricht in 2001. The paper on Cheating was written and submitted by the author in 2000.

Abstract

Nowadays, players at all levels of chess can profit from computer assistance during a game of chess. This is a new development and a serious problem for the game. This contribution lists the main forms of cheating and provides some occurrences from practice. The most prevailing one (Allwermann at the Böblinger Open) is placed in a historical context by describing previously noticed cases of cheating.

Finally, the problem of cheating is addressed at the highest level of play. What are the possibilities and how can we prevent cheating at this level? Since there is no clear solution, the problem of cheating remains on the list of issues to be addressed very seriously in the near future.


Part 4: Computer assistance at the highest level  

Potentially computers can play a decisive role at the very highest levels of chess. This was made very clear to me during the Super GM tournament in Las Palmas in 1997. In round four of this tournament Garry Kasparov played a very nice attacking game against the world’s number two Vishy Anand. I was following the moves with Fritz in the press room, together with some of the grandmasters present there. Here’s how the game went:

Kasparov,Garry (2785) - Anand,Viswanathan (2735) [B92]
Las Palmas (4), 12.12.1996
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be2 e5 7.Nb3 Be7 8.0-0 0-0 9.Kh1 b5 10.a4 Bb7 11.Nd5 bxa4 12.Rxa4 Bc6 13.Ra3 Nxe4 14.Na5 Nf6 15.Nxc6 Nxc6 16.Bc4 Nd4 17.Rh3 g6 18.Qd2 Nf5 19.Nxf6+ Bxf6

At this point Kasparov went into a deep think. Jan Timman started to speculate whether White couldn’t play the very forceful 20.g4. Kasparov’s second Juri Dokhoian immediately confirmed: “That’s what he’s looking at!” Yuri understands Kasparov’s thinking better than anyone else in the world.

Juri Dokhoian checking the 20.g4 line with Fritz in real time during the game, Kasparov and
Anand analyse after it six hours of play – video grabs from the CBM 56 multimedia report.

Meanwhile White had played 20.Bd5. The game lasted six hours, Anand defended very tenaciously and at around 10 p.m., much to the disappointment of Kasparov, a draw was agreed.

When he left the stage Garry spotted me and walked straight over. “I couldn't win it, could I, Fred?” he asked, with a troubled look on his face. It was a bit shocking: the world champion and best player of all times consulting a chess amateur, asking for an evaluation of the game he has just spent six hours on!

Naturally Garry wasn't asking me, he was asking Fritz. He knew I would have been following the game with the computer. “Yes, you had a win, Garry. With 20.g4!” My answer vexed him deeply. “But I saw that! It didn't work. How does it work? Show me.” He and Anand listened in horror while Juri dictated the critical lines. All of this was captured on video and published in ChessBase Magazine 56 (Feb 1997).


Kasparov and Anand learning the truth about 20.g4 from his second Yuri Dokhoian

The next day Garry did an interview with the German magazine Der Spiegel. He spoke about “Advanced Chess”, a new concept he has developed, which involves playing games in real time with computer assistance. He used the game against Anand from the previous day to illustrate his point. This is what he had to say: “That game provides us with new arguments for Advanced Chess. If I had had a computer yesterday, I would give you the full line with 20.g4 within five minutes. Maybe less. I would enter g4 and check all the lines. I know where to go. It would give me the confidence to play moves like this. Can you imagine the quality of the games, the brilliancy one could achieve?”

In the time since those remarks there have been two Advanced Chess matches in León, Spain. In the first Kasparov was unable to defeat Bulgarian GM Veselin Topalov, who made efficient use of Fritz to defend against the world champion. The match ended in a 3:3 draw, although Kasparov had just demolished Topalov 5:1 in a match without computers. In the following year Vishy Anand played against Anatoly Karpov. Both players were assisted during the game by ChessBase 7.0 and the chess engine Hiarcs 7.32. Karpov was quite inexperienced at operating a computer, while Anand happens to be one of the most competent ChessBase users on the planet. The result was that we were witness to an (unplanned) experiment of man and computer vs man. Karpov didn’t have a chance and was trounced 5:1 by his opponent. I am convinced that a player like Anand, using a computer to check crucial lines during the game, is playing at a practical level of over 3000 Elo points. However, this is the subject for a different article.


Addendum

We recently reported on a game played at the closing dinner at last December's Chess Classic. During this dinner at Simpsons in the Strand they stage a now traditional simul by the players of the Classic against the guests. Most tables have one or more strong chess players whose job is to guide rather than direct. One particularly high-powered table had Rachel Reeves, MP, the Shadow Chief Secretary to the Treasury, who was a UK U14 girls champion, Professor Vinayak Dravid, a leading nanotechnologist from the University of Chicago, the Indian High Commissioner Rajesh N Prasad, Jo Johnson MP, brother of Boris, and Frederic Friedel. Their advisor was Garry Kasparov and they produced the following game. Note that the GMs making each moves are abbreviated: DH = David Howell, LM = Luke McShane, MC = Magnus Carlsen, etc.

After the game some of the simul masters said Kasparov had perhaps been too generous with his advice during the game. But he vigorously denied this: "Before the critical sacrifice I said one word: 'wow!' Fred immediately jumped up and started to analyse with Rachel, and they worked out the sacrifice together, in less then a minute." He then proceeded to recount the story about his 1996 game against Anand in Las Palmas, given above, and how at the time it had become clear to him that a single bit of information, passed on to a player at the right moment, could have a decisive influence on the course of a game. "If Fred was allowed to come in and signal 'now!' in the critical position I would have worked out 20.g4 and played it!" That's right, it often needs just one bit of information – 'now!' – to change the result of a game.

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.

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 (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.
