II. Corona-Cup 2020 Rules

Post by RobertJasiek »

The II. Corona-Cup 2020 is announced here:
https://www.eurogofed.org/tm/uploads/to ... VKFoz2MQBM

It would have been nice if tournament rules (e.g., EGF General Tournament Rules) had been declared so that it would have been clear which Japanese rules are announced as "Japanese Rules", else if they had been clarified (e.g. as Verbal European-Japanese Rules) because KGS-Japanese Rules are ambiguous.

The Fair Play rules are:
"Fair play is a necessary part of the tournament. It’s not allowed to use any joseki dictionaries, AI or outside help. An impartial team of arbiters will check played games for signs of cheating using state-of-the-art anti-cheating tools. If the arbiters find it clear that a player has cheated, all of the player‘sgames will be forfeited and the playerdisqualified immediately. These rules will be enforced very strictly. Players 5-dan and stronger have to use webcameras during the game at least for offline recording. For other players this is optional, but strongly recommended."

Since I have never used a webcam (except on the iPad, whose storage would be insufficient for recording) and do not possess any for my PC, I need to understand what qualifies a camera as "webcam", how is it operated, can one use a browser for that purpose or does one need special software? Will one be identified as a "cheater" just because that software or video transfer via the internet fails or is interrupted? IMX, video streaming or recording are unreliable, so why should they be more reliable for webcams?

Fair play and prohibition of help are very good. (Except that I would allow help for disabled players to operate their moves or computer + webcam for transmitting / saving their moves and video recording.)

What are state-of-the-art anti-cheating tools? IMO, it is mandatory for such to include open source codes, decision-making and protocols. Will they include these so that each person can comprehend and reproduce the supposedly impartial and objective decisions by the Anti-cheating committee? By all means, go must avoid the mistakes of chess, where secrecy in the name of impartiality and objectivity destroys trust among all players and life-long reputation of allegedly convicted players.

If you don't have a webcam on your PC you can buy one for less than 10 € and plug it on an USB port, and you can record for instance your screen + whatever is on the camera with OBS Studio.

I see, thanks. Open source software sounds reasonable. However, on reading its description, I become aware of further problems: such (or other) software can mix or edit, that is, manipulate video streams. This possibility does not ease life of arbiters. A webcam should at least record both the player, and the display and input hardware he uses for playing. Such a rule, however, is missing. If some players use a webcam built into their display, it cannot safely be sure to record the display.

You will never be 100% sure that cheating did or did not occur, unless the video shows the screen and the player's hands, and is sent in real time to a live streaming platform. Unfortunately, such a protocol would be too complicated. I guess the goal of the recommended protocol is to deter most cheaters without putting too much burden on the players. Manipulating videos is possible, but doing an undetectable manipulation is not easy.

Just because you're paranoid doesn't mean they're not out to get you :)

jlt, live video is not good enough because a player might need to leave the seat to fetch or abandon liquid. Many players possess go books, which might accidentally be filmed resting in the background. Or opened instead of liquid in another room. Etc.

John, paranoia is a wrong description given the experience with chess and AI cheating disputes. Not all cases have only relied on the most obvious, unequivocal facts. Misjudgements are likely when relying on indirect "evidence".

Then keep all liquid and food at hand. Remains the voiding process, you are right that cheating may occur a couple of times during the game, there is no way to avoid that completely.

In my opinion the important part is that they adress the elephant and come across as prepared. It is also okay that they don't specify the anti-cheating tools - it's standard practice to defer cheaters from looking into them and finding loop holes. But they should specify the procedures when those tools identify an alleged cheater. Will there be communication with the suspected player before the ban? Will evidence be presented in any shape or form? Will there be an appeal commitee? (I'm fine if they don't do any of the above, it just should be clear. It's a private tournament and organisers rightfully have all the power - unless the sponser does.)

Videotaping players for a strictly online tournament seems to be "the state of the art" right now but it's cumbersome at best. I also hope someone looked into the European General Data Protection Regulation (GDPR). The reason we are in this mess is that go servers still don't have anti-cheating tools implemented. Are there actually any in development?

When I read this, I have to be honest and say that I'm tempted to enter and cheat a little, just to see if I can be found out.
If the arbiters find it clear that a player has cheated, all of the player‘s games will be forfeited and the player disqualified immediately.
I don't think that this is compatible with the rules governing EGF Grand Prix events. (Is this also an exception?)

Are you confident that if you start cheating, then you'd be able to stop?

Yes. I don't think that would be a problem.

Since the tournament starts tomorrow and my questions to the contact person of the tournament have not been answered yet, I describe the most important points of the current rules state:


It is unclear which Japanese rules apply. If the EGF General Tournament Rules apply (see §1), it would be the Verbal European-Japanese Rules (sekis without territory). Otherwise, one can also asssume that the KGS-Japanese Rules apply (sekis with territory).

It is unclear if the EGF General Tournament Rules apply.

It is unclear if "winner of mutual game" only applies to exactly two still tied players.

It is unclear how the Anti-cheating committee fits into the arbitration system of Referee, Appeals committee and (if the EGF General Tournament Rules apply) EGF Rules Commission, if the Anti-cheating committee only gives recommendations or is an arbitration instance of its own, which, and hence if the players are granted their right to a fair trial according to international law.

It is unclear what are the state-of-the-art anti-cheating tools.

It is unclear if they include open source codes, open decision-making and open protocols so that each person can comprehend and reproduce the supposedly impartial and objective decisions by the Anti-cheating committee and arbiters.

It is unclear what a webcam must record, what happens in cases of software bugs during the video recording and if closed go books in the background may be filmed.

I doubt that "state-of-the-art anti-cheating tools" really exist, no one seems to have heard of such tools. My guess is that if a player is suspected of cheating and complains, then Antti Tormannen will first make a human analysis and try to find suspicious moves, then compare with input from and AI, and then compare with the video. If at each of the suspicious moves the video is unclear, absent or suspicious, then the suspected player will be eliminated from the tournament.

So IMO the video is there to disprove any cheating suspicions if any, it is your responsibility to make the best recording possible of your hands + your screen if possible.

(emphasis mine)

:lol:

By the same token, it is unclear how this forum grants me the right to a fair trial. And how is it handled on KGS? War criminals everywhere.

In all seriousness, people here like to go full Boston Legal when it comes to online cheating. But there is a big difference (not only legally) between state level jurisdiction and a small privately organised event.

Me, too. How are such tools validated? You don't have to reveal how they work to say how they have been validated. :)

Hmmm. Well, they might be state of the art if state of the art is by guess and by golly. ;)

Good point. :)
