Another case of cheating?

As the arbiter observed, Ricciardi did not once get up during the game and constantly had his hand under his armpit. He was also "batting his eyelids in the most unnatural way". Finally, the arbiter decided to check Ricciardi with a metal detector and it turned out that the player had a camera hidden in a pendant around his neck. The camera was connected to a small box under his armpit."

Hello Ted, Nice to see you posting in the new forum, I was wondering where you were :)

It would be interesting to hear/read this chess players reason for cheating. Understanding "why" these people cheat is an important part of stopping this problem.

Simply stating: "Oh they do it to increase their ELO" or "Oh he just wanted the prize money" is not much help.

I think the issue for these people is much deeper psychologically.

Fernando is a psychiatrist, perhaps he has some insights :idea:

Cordially,

Sean

A quick run in move error evaluator. The average error of that guy is indeed low. DECnt is low means he is not in trouble most of the time and high EECnt means his move is better than sf6 at 0.3s/pos in 2 threads.

Code: Select all

Move Error Evaluator v9.5

Moves Error calculation based from Stockfish 6 64 POPCNT and players from
Event: 57^Imperia, after round 6.0

Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz
Analyzer id name Stockfish 6 64 POPCNT
Hash 128 MB, Threads 2, MoveTime 0.30 sec/pos

Legend:
Rank     - ranking based on low average error
AveDepth - average depth reached by the Analyzer in analyzing those positions
AveError - average difference between the analyzer and player score, in centipawn (1p = 100)
DECnt    - count of positions where player move score is below zero and analyzer move score
         - is better than player move score. This is called Dangerous Error Counts
E300CP   - count of positions where player has blundered by 3 or more pawns
E200CP   - count of positions where player has blundered by 2 to 2.99 pawns
E100CP   - count of positions where player has blundered by 1 to 1.99 pawns
E50CP    - count of positions where player has blundered by 0.5 to 0.99 pawn
E20CP    - count of positions where player has blundered by 0.2 to 0.49 pawn
EECnt    - count of positions where player move score is better than analyzer move score

Notes:
1. Analysis of positions start at move 12.
2. If best score of Analyzer is already 6 pawns and above and the score of player move
   is also 6 pawns and above then error for this position is set to zero. The more cases
   like this only proves that that player is able to maintain its advantage and this
   will minimize its average error at the end.
   On the other hand if the best score of Analyzer is already below minus 6 pawns, no further
   analysis will be done, and this position will not be included in error calculation.
3. When a player move is a blunder that brings down the score below minus 6 pawns,
   error for this position is set to -6 pawns in the calculation. The reason being once
   the opponent found the refutation, the succeeding positions will no longer be evaluated.
   It is just fair to penalize this heavily to also reflect on the average error which
   should be high for players that have more game loses or fatal blunders.
4. move_error = analyzer_score - player_score.
   analyzer_score = score returned by the analyzer after searching for a given amount of time.
   player_score = score returned by the analyzer after searching the player move for a given amount of time.
   AveError = sum of [move_error] / totalPos.
5. Error is increased if the score of position after player move is below zero.
   6x error if &#40;score <= -200 cp&#41;, 5x error if &#40;score <= -150 cp&#41;, 4x error if &#40;score <= -100 cp&#41;,
   3x error if &#40;score <= -50 cp&#41;, and 2x error if &#40;score < 0 cp&#41;.
   The idea is only those errors which will result to inferior position should be penalized more.
   If the increased error penalty is more than 6 pawns, error is set to 6 pawns.
6. Regarding EECnt or Analyzer/Engine error counts, this is a counter check to analyzer where the human move
   is sometimes better than the analyzer move, this is because the analysis time given to the analyzer is
   shorter and also perhaps the position is complicated that bigger depths are required to determine
   correct assessment of the position.
7. DECnt or Dangerous Error Count is an info to see which player is probably always in trouble.
   See also DECnt in Legend section. Strong players usually have low count of this.
8. Analyzer error margin is a value that is used to decide whether to save the position or not
   when player move score is better than the analyzer move score. If this is set to zero then
   all positions will be saved. If this value is set to 10cp, then only those position which the player score
   is higher than analyzer score by more than that margin will be saved.
I have uploaded the evaluator somewhere here. You may use it to run the epd below, to get the summary based from your setting.

Below is what the cheater told later to the press after he was caught with
a hidden box in his armpit and a minicamara wired under his t-shirt:

=>Link to the source

Ricciardi was removed from the tournament and his games declared lost. However, he denies that he cheated.

“It's only envy,” he told La Stampa in a follow-up article. “I always knew my potential, but I was never able to express it. It's all false. I've played for 30 years, it's a genuine passion. But only now, thanks to yoga and self-training I managed to free my mind from tensions and emotions.”

There are countless examples of cheating in chess, and only this year there were two clear examples that were reported on by international media.

In April, at the Dubai Open GM Gaioz Nigalidze was caught using an electronic device in the toilet. The player, who happened to be the reigning champion of Georgia, was expelled from the tournament.

In the same month an amateur chess player was caught cheating at the Dr. Hedgewar Open in New Delhi. The 1500-player, who beat several much stronger opponents, was caught after round five carrying two mobile phones strapped to his legs.

GM Emil Sutovsky, the President of the Association of Chess Professionals (ACP), on Facebook expressed his worry about this development that affects chess very negatively.

“I keep repeating it — we have to enhance the fight against this plague of the modern chess. Those rare successes, catching several primitive cheaters with their gun smoking shall not mislead us — it is just a tiny pinnacle of the iceberg. It is THE PLAGUE, and it presents a deadly threat to chess.”

I think a lot of chess players at the bottom are inspired my grandmasters at the top. So when strong players cheat, it sets a bad example for lower rated players.

Ferdinand I looked around and tried several CCC searches but the latest version I found was 9.0. Would you mind to post again a link for the newest version of MEE?

P.S. It would be nice to have all your interesting tools together somewhere for download.
