Can my chess cheating device get past the metal detector wand commonly used at chess tournaments to screen for cheat devices? In this video I also test out a faraday cage to see if it is a viable solution for preventing radio signals reaching my device. This device was made in response to the chess cheating scandal involving Hans Niemann and Magnus Carlsen, originating at the Sinquefield Cup 2022.

one of the theories is not only did it send the move, but it also received input from the player themselves. by contracting your muscles, or tapping your foot, etc. you can input your opponents moves and the device outputs the move you should make. this means a faraday cage would be useless as their are no signals needed to operate the device.

My wife said that I would have to notify TSA agents (US airport security) whenever we flew. I said, "Let's wait and see." It's never been detected once, either in the US or abroad, and we have flown at least 30 times. Even when I was wanded it's never been detected. So I wasn't surprised at all by your findings.

Same. I have a titanium rod in my femur, it has only gone off once when I was going through India in 2015. Im convinced that they had a different detection method at the time because it went off through the walk in detector and the wand, but they were the very old models. Since 2018 or so, flew internationally many times and India; never has gone off since..and most of the time it's been after they made a "security" upgrade to have that 180 degree scanner instead of a pure walk through metal detecter

They have done this before.

GMs at that level can look at a position and say "it's even" or "they might be better" but completely overlook an important tactic. If they know a specific position is better, all they have to do is use their time to find it. The WCC just concluded, and you can see that most players only go into deep thinks maybe twice a game. Even a 30 minute delay would not be enough in classical if someone got help in a very critical position.

The technique works so well when actually used as a buttplug since anal tissue is highly sensitive. Since most metal and most buttplugs are surrounded by silicone, so imagine if it is also hidden in human flesh.

It’s such a brilliant idea that can be prevented with proper measures sure but realistically whoever came up with the idea is a madlad.

Another thing to think about is that if the cheater is already a good player trying to win a tournament (rather than a relative novice trying to beat a much better player), signaling every move isn't necessary for a cheating advantage, in theory you need to transmit much less information. Grandmasters have said that even just being told once per game whether or not an engine evaluates the current position as nearly equal would be enough to become the top player, since you'd always know at the key decision point whether it's strategically better to play for a safe draw or a risky win. That's one bit of information once per game. That might expand the number of possible cheating methods.

nothing has prevented people from making electronics that are hard to dected by a metal detector. Example: aluminium, stainless steel harder to detect than the copper and steel. All you have to do is acquire the same metal detector than they use in the tournament, and start removing the problematic metals until it is no longer detected. If there is money to be made in the end, people will do it. You can make an antenna out of aluminium, and can make a servo out of stainless steel and PLA (custom made), the wires and tracks on the PCB can be in aluminium... and so on.

I didn't expect the silicone to completely hide the metal of the device from the metal detector. I will say, as a former event security worker, those metal detector "wands" don't miss things like a watch or phone or anything. It will pick it up 10 times out of 10. So if you've ever had something slip past, it's because the security person let it go. They usually have the wand set to vibrate so only they know if it goes off, and they can use their own discretion to decide if they need to investigate further. The wands are pretty effective, so it is really interesting that a butt plug was enough to hide the electronics from it. It really gives credence to the sex toy cheating theory.

However, a computer which implements the chess algorithm could also be fit inside the suppository device without difficulty. The only hard step needed to get this to work within a Faraday cage is to have a way to input the moves on the board to the suppository device while it is in its position.

Yet one of the strongest theories today is that Niemann specifically picked the kinds of tournament without strong anti-cheating measures and used those to inflate his rating (another point here is that his rating always plateaued, then shot up massively and plateaued again - no improvement during fair tournaments and huge improvements during the ones he could cheat).

Hi Mike! As somebody commented, there's no problem running a small CPU capable of running stockfish locally in your... behind (any stripped down smartphone will do). The problem is feeding it the last position locally, but that's also possible. A simple switch can do it in the device itself, or an electrode to sense muscle twitching and send a variation of the protocol to make it bidirectional and reject false/involuntary messages, and with no RF needed. Unfortunately, a motivated cheater with the technology and resources will be extremely hard to detect, since you can even make the electronics almost invisible to metal detectors and RF detectors. If the cheater is a GM he can also avoid moves that are suspicious (in your game, you gave it away by doing moves that for a high level player is obvious only a machine will do), so using the device as a strong advisor instead of just relaying the moves will be pretty much impossible to detect. Only way I can think of would be a very sophisticated and impractical full body scanner.

[@yehudagoldberg6400]

[@Dayanto]

As others have pointed out, the actual non-joke method of cheating would be with a device in the shoes. You could send signals back by tapping on pressure sensors, and this would be even more efficient with one in each shoe. With only a bit of practice I was able to tap moves (from x/y, to x/y, 12 bits total) in about 10 seconds including the time to look at the move. I did it by splitting the board in half and tapping left/right for the side it's on, and repeating this process until you have the position. Then you simply do the same for y, and the other x/y pair. If you instead memorize binary representations, it's even faster, and I think a pro should be able to do it in under 3 seconds. To send commands like "undo", you could tap both feet at the same time, and you could even have it verify moves by sanity checking them and reading them back to the player for confirmation. All of this would work inside of a faraday cage, but if they also check for weak signals, you might have to do it single-footed or physically connect them with a thin wire running through the pants, or directly with metal contact points on the sides of the shoes.

Wild idea - if you put a potent (pun intended ;) enough chip into the device, so the chess move calculation could happen on device - and then making a "muscle contraction Interface“ with a force sensor i.e. being able to enter the latest move, with a similar code you used to transfer the desired position, into the device by contracting your sphincter. well you’d have to use these muscles quite a lot, I’m not sure what kind of consequence this might have.. but still, this would make the device fully independent.. the player cheating wouldn’t be relying on an external person and neither a faraday cage nor a signal jammer would be sufficient to block the cheating device. The only means to intervene would involve the player getting physically examined and or more sufficient detectors to find the device before the game starts.

[@jasonklosheim7138]

The reason why the metal detector likely doesn't pick up the metal in the device is simply because there isn't enough metal surface area in the circuit board to create a noticeable magnetic field for the detector to read. Basically, it is a geometry issue. The reason why it signals briefly when moving quickly at it is because of Gauss's law. The quicker you change the electric field's flux the stronger the eddy current and the more detectable the induced magnetic field is but only for a brief moment. It is also very sensitive to distance. It's something like to the 3rd power that the strength of the magnetic field diminishes per unit of distance.

That's not true though. He took it out of the casing, it detected it flawlessly. That disproves the surface area thing too. The scalpel blade definitely has less area than that battery. Yet, it doesn't detect the battery in the casing, but does detect the blade. It's obviously not surface area, something else is keeping it from being detected.

[@raketexyz]

there are just way too many signals on way too many bands to actually differentiate a cheating signal from the ton of signals all around us.

Too much interference, you can make these devices do complicated things. It would be simple enough to sync a device to transmit certain frequency for a bit and switch to a different frequency. Rinse and repeat, you wouldn't know any better.

Something that would be quite fun to watch would be a competition between people to see who can cheat at chess without being detected. Layers of difficulty (like the Faraday cage) could be added in an incremental manner.

[@JueTheRoux]

It's illegal to put large signal jammers in public places like where chess tournaments are held because it blocks 911 from being called so that won't work

[@samuelcoen9254]

I remember hearing this wasn’t viable because it’s illegal to install a faraday cage because people must still be able to call helplines in case of emergencies

[@GoErikTheRed]

I feel like this would have to be an exception, because there's always multiple people present both inside and outside the cage. If it is a legal problem they could always just run a landline into the cage

[@jakistam1000]

You could have staff stationed outside the cage, observing the match, and they could call emergency if needed. Or a landline phone.

[@omnitroph1501]

Yeah, a landline phone would solve this handily. You'd have to have physical cables for the stream anyway, so it's not that much extra effort to run a phone line too.

[@PeteQuad]

It was amazing to me to see so many people in those early chess cheating videos talk about how impossible it was to cheat in person, and then to exclaim about the wanding and security measures. Those wands are junk and always have been. They only catch people casually carrying something they shouldn't, not those who are purposely carrying something malicious.

[@Rose_Haw]

I was not expecting this, but this is wonderful

[@why_though]

Yeah a Faraday cage would work, but if you also did the chess computations on the device, you wouldn't need any signals. You would need to tell it the opponent's move though by clenching your... leg... in a pattern. And as a bonus you improve your pelvic floor health which is nice.

[@laizerwoolf]

Not to mention you have to convert chess annotations into clenching patterns. Another limitation to this method is that you have to keep the chain of input continuously from the beginning till the end, thus making the game very suspicious when people analyze it afterwards.

[@why_though]

@@laizerwoolf Actually the patterns thing is already done anyway in the original device, you just have to reverse it.

You need to put the players into a Faraday cage. Someone sitting in the audience could otherwise still locally host an instance of Stockfish and transmit moves that way.

[@terriplays1726]

Thanks for testing it with the metal detector. The result was not what I expected.

[@jag8926]

I think a faraday cage around the entire room would be impossible for the same reason radio jammers are. If someone were to need emergency services, no one could make the call. Maybe there is a way around it, but its a challenge even aside from putting metal mesh around a huge tournament room. Its the typical engineering paradox. No matter what you do, someone can just engineer another way around it. Whether its firearm laws or cyber security. There is ALWAYS a way around it. Its just about making it cost prohibitive to do so.

[@marcello9476]

step outside the room to make a call. you dont need the entire building to be locked down

[@Syv_]

Is this serious? Lol.

[@progamasEjogos]

Just the chess room, and the ones outside could see the players and call emergency if necessary

[@luongmaihunggia]

Use a wired landline instead of wireless phones to call the hospital. Have medical personnel on standby. Come on, idiot. There are so many easy alternatives. Even without using a Faraday cage or signal jamming. We could use a radio signal detector. Anyone cheating through broadcasting radio waves will be picked up by the detector instantly.

[@cameronwebster6866]

Who's Mike 4?

[@Illogical.]

One could still massively reduce the amount of code needed in the algorithm, so it could run in the device, and the user would have an input method through some muscle, that can't be controlled without being detected by viewers. If it all runs locally, one could still cheat. It would also be even harder to detect.

[@andersaskjrgensen5468]

it takes an amount of computing to recommend good chess moves that can't be done on a normal Arduino fast enough. You would need a mobile-phone like processor and a bigger battery that could get hot

[@joefoster4635]

Metal detectors produce a magnetic field which induces a magnetic field on any nearby metal. This induced field then interacts with the metal detector showing, indicating a metal is present. If you wack the metal fast enough perpendicular to the field lines this will induce a stronger secondary magnet, hence it only detects when you hit it

[@OneStepToday]

Farade cage will definitely the best option. This was conclusive and very useful, interesting. I thought he was innocent but now after knowing that the metal detector doesnt catch it at all , i now think he must have uses a device.

[@sickoslater]

I think it's unlikely (although, not impossible lol) he would have used his butt. If the metal detector can't even sense this relatively large device, all you'd have to do is strap it to your leg and put in inside it your underwear or something

[@yordanyordanov3785]

One problem with the Faraday cage is that if your accomplice is inside it with you they can still send you the signal. But i am curious if you could employ a signal jamming device within the area. First i think it would be cheaper and more convenient for event organizers. I'm only curious how good signal jamming devices stop that type of radio signal like bluetooth. And how easy it would be to beat it.

[@christinanull5098]

signal jamming is not only illegal but also a safety hazard as you need to be able to dial 911

[@yordanyordanov3785]

@@christinanull5098 Yes, but what if it is highly localized? Like being only powerful enough to cover the stage with the players. After all you just need to disturb the receiver.

Signal jammers also play havoc with medical devices like pacemakers and insulin pumps, and I think some kinds of hearing aids use bluetooth too - I know I'd be pissed if I ended up in the hospital because a signal jammer screwed up my insulin pump

The cage will only prevent an external signal and the cheater can use some sort of input system (muscle clenching, gyroscope, button taps) to input opponent's position data and run a chess engine on chip.

[@DiabloVal]

PS. a much better place to hide this device would be in the sole of the shoe. you can press buttons/tap etc easily and there is plenty space for a much more powerful device

[@13thravenpurple94]

Great work Thank you

[@UnfiItered]

Faraday cage will only block signal from going in or out of the cage. If both the incoming and outgoing signal is inside of the cage, it won't stop the devices. You need a faraday cage private room in order to solve the issue. Private rooms that only the players and referee are allowed in. Players are checked for hidden camera before entering. The only camera is the official one that will broadcast the game on a 5 min delay time. Video will also be synced to a signal grabber. If the signal grabber notice a pattern of signal being sent and received when a player is making a move. That game is ruled sus and investigation is to be considered.

If the player have both the transmitter and the receiver on themselves a isolation box wouldn’t work. For example you could record the game by pressing something small with the same number system as the vibration (1-8, 1-8). Or even more simple: left feet push letters, right feet push numbers. Same device could record the signal and return the best move?

Love it! Show the problem and then show a solution. A clean in and out… unlike the device! Can’t really think of a better way of covering this story to be honest. That is until the Netflix movie/show airs 😉

They would have to have only the two players inside the cage then too. If the potential other person who is sending the signal is also inside the box as a spectater, it would still work inside the cage I assume

And knowing the fact that with a little bit of additional work, you can design an even smaller PCB, containing the MCU and the nRF21 transceiver chip... and you can even go for the smaller footprint versions of these devices, or go even more integrated and use a nRF51-series chip that contains the transceiver and an ARM CPU.

[@x9x9x9x9x9]

The funny thing about metal detectors is they aren't always on high. So they will miss a lot of objects. Whats actually more insane is how many times I have gotten on a plane, in america, with a razor blade in my wallet. Or gone into a court house or somewhere thats not just a metal detector but x-ray machines. Granted it doesn't exactly look like a normal razor. They are "Logan ANL270 blades" so they don't really have a sharp point for stabbing just an edge for cutting. I keep one in my wallet all the time because its a handy thing to have in case I forget my pocket knife or something. I just forget its in there while going through these things.

[@UnnoneWandering]

I'm just imagining someone paddling all the chess masters with a metal detecting wand while searching for certain devices. I think Hikaru's face would evoke tears of laughter.

[@testboga5991]

Depending on the type of network the device uses, it might be very hard to have an effective cage. Cellphone signals get through a lot of shielding.

[@CJtheThird]

I think the only way to make the the most secure tournaments would be to only allow the players to sit in a room isolated from all other people except for arbiters. It would mean that no one would be able to see the games being played and thus would not be allowed to forward the cpu moves to the players. Instead of blocked the cheating devices, block the accomplices from being able to send the signals.

[@flacsomtodosclas2165]

So no one would go wacht and the chess competitions would loose relevance and die

[@CJtheThird]

@@flacsomtodosclas2165 IDK maybe they stream on delay to a gallery or public idk. Im just saying the only "fool proof" way I think can of is isolation

[@DMSBrian24]

You can also send the signal from within the cage, unless it's only the players that are in the cage. The issue with this is, chess is insanely underfunded, it makes 0 money and is mostly done for fun, even at the "professional" level with the exception of the very top. As such, many tournaments, even some of the pretty important ones with top players in them, take place in regular, rented buildings like sport halls, hotels and whatnot. It's simply impossible, aside from maybe top 3 tournaments, to host matches in such setting, mostly because such buildings don't really exist in the first place and the ones that do would be too expensive to rent out for the sake of an event that doesn't make money in the first place.
