Yeah you said it right. It is really an amazing game because not only it is enjoyable to play but it also has a benefit to sharpen our brains. You can click the link that he posted to see how the game went thru and you can also click on the subscribe button as it is the account of one of the player names Magnus Carlsen. You can check his other videos to learn more of him and see his past games.

I was looking at the other player named Jan Duda on youtube but I can't seem to find his official account. I think the guy didn't set up a youtube account yet. You can try searching them on google and see if you can find other information in regards to them.

In the long term, it's not really going to be sustained because the cheater can be caught by an instance no matter how good he is in hiding.

The time will come that he'll uncover the cheat that he's been doing and all the tricks despite measures being made by the organizers if it's an online tournament.

But with the loosening of restrictions worldwide, if there will be casinos that are going to put this into their book. They'll probably only going to take those matches that are live and F2F tournaments.

I have no idea how big cheating is on the chess world, but I would expect it to be very small in the higher levels. Once you reach IM or GM rank everybody knows each other. The people have been playing chess since their teens and played against each other in many tournaments. It's not like one guy just using cheat software for 2 weeks and becoming a new chess professional. That's why the ELO system is so important. I think that online only players with a long track record can play each other. The potential backlash from cheating, like ruining your career, being banned for life from chess tournaments and paying a big fine should prevent anyone professional to do such a think. For small online chess tournaments with no professionals I think that betting on it is no real option because of the cheating risk.

As long there would be no involvement of cheats then it would really be giving out  that confidence on having a fair game but we know that cheating does exist on this sport through online which it do really makes hard

for us to trust on dealing or making out some competitions against other people and its not surprising that gambling sites doesnt offer this one yet it wont be something profitable for them
or doesnt really have much demand if you do ask me.

As long as there is money involved I don't think cheating will be out of the option since some people will do everything even cheating just to have the wagered money or the pot money. The OP was looking at some gambling site for a p2p chess online which I don't think exist yet.

ya.ya.yo!

yes, that's why ethics and fair play is really important,

regarding websites not offering chess
maybe because they think there's not a lot of demand?
personally as much as I love chess I wouldn't be so interested on playing online for money, maybe in real life for fun but not online where my win rate is close to 50/50...

Chances of people/players to cheat gets higher when there's a huge money at stake as it could give difference in their life even for a short time and that is where greediness kick that's why people tend to cheat just to secure that the money will likely be in their possession at the end of the day or tournament.

For now, there's no gambling sites about the chess yet but maybe soon there will be some.
