Catseye
I advised the Captain of Planet Chess, and he removed Catseye.

Thanks, GMForsythe
I received the following message this morning:

Thank you for your correspondence on player "catseye." I have removed him from my team and if word gets around hopefully no other team will add this player as a member. Ed.

I’m posting this here to facilitate word getting around.

Good job, everyone. Perhaps catseye will get “the message” this time.

Thanks to all who wrote the team captain.

And...
Thanks to you, Wasatch, for doing the hard work of analyzing his pattern of dishonesty and bringing it to the attention (and action) by GK and everyone reading this thread.

Thank you for all the messages on how to detect and expose a cheater. OTB chess is more difficult to cheat than online chess but still there are some cheaters out there if the prize money is big.

Several years ago, I played OTB chess in the reserve section of combined B & C rated players. My USCF chess rating was C <1600. B ratings have < 1800. I beat them all in 2 days, 6 rounds Swiss system and became a champion. My B rated opponent was a senior citizen and older than me. He made some mistakes and so I won. When we get older, our memories get poorer and elderly chess players can lose the games. The tournament ended peacefully without any accusation of cheating or wrongdoing.

Please watch the above youtube video first. Hans Neimann is a young GM who beat world chess champion Magnus Carlsen easily. MC got upset and angry for losing an idiot. He accused the opponent of cheating. I have watched that game played between the two. Correct me if I am wrong. I don't see any evidence of cheating by HN.
youtu.be
HN is banned from playing again in US- St. Louis chess club for his rude behavior, damaging the hotel room he is staying and cheating. IMO, he is not worse than former world champion Bobby Fischer. He already paid fine for damages he had done to the hotel room. My point is that he should not be banned from playing chess again. Otherwise, we will lose a very promising young chess player. On the other hand, just like Bobby Fischer, HN makes chess more interesting and more people will attract/play chess IMHO.

Re: Make sure he is not the eye of an innocent Pussycat.
Chess is supposed to be a gentlemanly game. Poor sportsmanship deserves punishment. While I would not hold Bobby Fischer's behavior as an exemplar of good sportsmanship, I have never heard of his destroying property. Niemann deserves no particular credit for paying for the damage he did. This was simply a legal obligation.

According to your narrative, HN is banned from one and only one venue. He has not been banned from playing chess again - just not there.

Without evidence, MC had no justification for accusing HN of cheating. I suppose MC is experiencing difficulty handling fame.

Innocent Pussycat Eye?
The deck is stacked against that.

Queen sacrifice on move #9.
game

Queen sacrifice move #11
game

Queen sacrifice move #10

Queen sacrifice move #20

Queen sacrifice move #18

Queen sacrifice move #14

All let’s play consecutive losses, and this never occurs on team games? Never?

This is deliberate.

ace-of-aces, please forgive me. His surname is Niemann, not Neimann. I have a similar surname and I know how irritated our family gets when people misspell or Anglicise our surname. BTW, Hans did admit to cheating on an online platform to gain a better rating when he was very young, and that is probably why there is suspicion on him for cheating now. And no, we are not close family as he is Niemann while I am Nieman (one n at the end) and our last common ancestor is at least eight generations ago, but according to my uncle maybe as much as ten generations ago.

Back to the focus of this thread, I downloaded 150 random games of catseye and I am running it through my algorithm machine at work. I expect an answer in nine days. Luckily all my algorithms are up to date, with enough extras in the commander’s safe not to interrupt this operation, and we are all in a workshop this week. I’ll update you on progress once the machine is done.

Another good point. “I’m going to drop my queen in private games 9 times in a row all on the same few days.” Actually, we can’t know what day each biddy was slain, just that he hates her when it’s a private game. Gone girl within 20 moves.

Surprising Riaan is devoting 9 days of processing time to analyze this, but the results should prove interesting. It will be a good test of his algorithm, given what we have already determined.

Catseye’s games
Ok, you need to pull out the games where he needs to win and on the flip side lose. He loses to moderate his rating in games where he does not need to win. He stays in a narrow rating band to stay in the lower rated tournaments.

Again, the technique I use is identifying his critical games and then use GK’s computer to see if he has an error-free game. They were not hard to find. He won all of those in the low 20 moves with crushing attacks.

On team games, he should be trying to win enough to turn each match, i.e. he may lose one or two if it still results in the team getting a win…at least, before he was kicked off the team.

Consider this?
We could follow whatever tourneys he is in and alert the organizer so that he will eventully give up and go elsewhere. Is it possible to do this retroactively? Look at the tourneys which he has won and then alert those organizers? Just a thought.

CATSEYE A CHEATER AT GAMEKNOT
Ciao
IT'S ESSENTIAL WORDS GET AROUND SO THAT NO CAPTAIN WILL ACCEPT HIM IN THE TEAM ANYMORE.
It is also important that the gknot Administrator intervenes to delete his account, so he will lose all the games he still has in progress! Thank you all for your efforts to stop and hunt down any cheaters and hoaxers. Piero

Hi gmforsythe,
Fair and correct . However, consider that at this moment he has no other matches other than those of Team match. Since he was removed by the Captain of Planet chess, he is not currently registered with other teams (I follow him hour by hour, I don't lose sight of him) and therefore he does not need to lower his rating in other games that do not interest him.

I would like Gameknot to intervene to delete his account so he loses all the games he has in progress without harming other players anymore.

I am fairly sure Catseye has been restricted from mini tournaments and may be restricted from GK tournaments. I think he got a taste of “winning” by topping a GK tournament in the past and then continued the machine use for the minis. This is also a pattern used by the player stormtracker who finally left a few years ago. But GK never banned stormtracker, they just restricted they type of games he was allowed to play and he got frustrated and left. If you want to play where they ban cheaters to have to play at Chess.com. I prefer the range of features here, having played at both at times.

piero51, it sometimes take a while for them to answer.

I want to mention this again to captains I do not know:

Early in 2019 I joined the Pretoria Chess Club, specifically to find a tutor to improve my game. At the time I sent a message to this effect to several opposing captains as well as to members of my team. Towards the end of last year I surprised myself by breaking 1500. I think I was doing too well, and was starting to match with players that were just too strong. I fell almost 170 points. I am climbing again slowly towards my goal of +1400.

To confirm my involvement with the Pretoria Chess Club, please follow the link on my profile. It will take you to the home page of the club and there you will see that I am now the Secretary of the club. The web page is not fully developed yet.

GK makes it very hard to communicate and they almost never toss a player for anything.

I did threaten to quit and take a number of players with me to Chess.com and they then banned catseye from mini tournaments but said nothing to me.

The fight to get stormtracker banned was similar. I know a number of you helped to get him driven off.

You’ve gotta like playing at GK and you’ve gotta be patient.

Sooner or later we’ll drive out catseye, we’ve just got to get the message out.

Informing other team captains is critical in my view. If no one takes him on teams, then he can’t bend team play. But then, he may try to start his own team like stormtracker. But then, you don’t accept play from his team.

Eternal vigilance
There seems to be an endless source of methods to cheat. We need to work cooperatively to spot them and report their behavior. If catseye gets banned, he/she could then start a new account with a new name. The key is to watch for ANY suspicious activity and then pass the word around. Eventually (hopefully) cheaters will tire of their childishness and leave on their own. This is the most effective way of ridding ourselves of them. New ones will continue to pop up. I guess it's sort of like "whack a mole," but keeping a collective eye out for this is the most effective weapon we have.

I answer to wasatch:
he could change accounts and then it would be more difficult to find him. I would just like to think about playing and having fun and not be careful about everything when I assign an opponent to my players.

How recently did you contact GameKnot? I've sent several messages about other things in the past year with no response.
wasatch
15-Feb-24, 11:39

My last contact with GK was 1.5 years ago. They responded once to say they were looking into it. But no response to the next 5+ messages.

The hook catseye is on is the same that stormtracker was on: catseye is in the top 20 tournament players and stormtracker was #3. Neither wanted to give up all that work. One of my friends here at GK thought catseye was stormtracker with a new name but I doubt it as catseye is dumber than stormtracker and has repeated the same mistakes.

If catseye changes name, I count it as a win as some other deserving player can then get into the top 100.

How to avoid cheaters? Play GK-Live chess & with shortest time.
GK now has Live Chess with shorter time in each game. The quickest game you can play is 3 minutes without any time increment. The good thing about GK-live chess is that you can be rewarded with + or - score. When we play rapid or blitz chess, you don't have much time to think about the best possible move or consult with any chess books and coaches. Chess players can make mistakes with shorter limited time span in games.

If you still want more quick chess games, go to chessplayer.com from chess base where you can play one minute bullet chess game. When you play those quick chess games, you should prepare with mouse-cercises (mouse exercises) first which is a kind of reflex action without much involvement of higher brain cognitive function.

Personally, I don't like this fastest 1 minute bullet game because the game will end without win or lose but who can win the game by fastest mouse movements. The analogy is similar to running a 100-meter sprint and carrying a king chess piece. If you can finish running ahead of your opponent with a king piece in your hand, you will win the game.

Right. The problem of cheaters exists in Team matches. Elsewhere it's a personal choice, it doesn't involve teams

I checked in on my algorithm machine earlier this morning. It was standing at 7% about 6 hours ago.
piero51
16-Feb-24, 03:27

Sorry Riaan, is it a partial or final result? You've only looked at the Team Match games, I think, because that's what we're interested in. Exactly what is the purpose of your research?

piero51, I downloaded a random sample of 150 games. I deliberately made it a random download, to have a look at ALL his games, not just the team- or tournament games. That way I get an overview of ALL his games, and the breakdown is more complete. I am doing this to confirm what the allegation is to my own satisfaction, because I believe that one is innocent until proven guilty, not guilty until proven innocent.

As a cryptographer I am lucky to have access to such a tool at the office. As an analyst I can calculate the probabilities of the answer I get. When I get the answer, I shall share with you what I found. My algorithm machine can predict with a confidence of 0%-100% which algorithm was used- provided I have the algorithm in hand to compare against. If an algorithm has been used but I don't have it, the probabilities drop down significantly, but one will still be able to predict that an algorithm has in fact been used, although unknown. I will then search for new algorithms and upload those to my tool either manually (which I rarely need to do) or automatically.

My algorithm machine is updated automatically daily*, thus I am fairly confident that I shall be able to identify the algorithm he used with a great deal of accuracy. *The exception is when I am running an analyses, when updates are not done because the analyses take all the processing power. Even the GUI is slow and intermittent with blank screens between operations constantly.

As an analyst, a prediction of over 90% is good enough to convince me of wrongdoing. Between 80%-89% is a good indication for further investigation, and between 70%-79% will warrant suspicion at the least. Below that number is not worth looking into.

The private games can be compared to team matches and tournaments respectively and in combination, to find other statistics as well.

I am lucky to be trained both as analyst and cryptographer. That is a very rare combination, at least in the South African Police Service. There are almost 200 analysts, only 22 cryptographers, and I am the only one trained in both disciplines. This is the reason why I have been mandated the tasks around the algorithms: building new ones every six months, identifying and analyzing attacks on our networks, and putting measures and procedures in place to prevent breaches and leakages. Besides the two skills mentioned I am also trained as a network security specialist.

Just as an aside, my old friend who passed away recently, stalhandske, was quite impressed with my combination of skills, which also included more practical skills from my earlier years as a younger man in the SAPS. These include investigations, communications specialist, sniper* and tracker. I am also a photographer and profiler. *I lost my certification as sniper just over two years ago when I couldn't pass the tests we have to do twice a year- mostly due to natural loss of eyesight as I grew older. But, as snipers say, just because I am old doesn't mean you are out of range!

surely you won't get a pattern if the player just randomly throws the game by a sacrifice?
