Can anyone tell me if you know any website where you can play online chess with other people
and that both man can invest crypto and winner takes it all?
I don't think that there is a legit casino where you can play chess tournaments.
If you want to play chess with other people, you can go on dod.com - it is an affiliate with facebook as well - and you can find a lot of skilled players there and test your knowledge on chess with others.
