Here's some site that you may play against your friends or challenge a bot.
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?
Betting in chess sound as a nice way to gamble, the problem is people could use a computer in the hard level to play chess against other people, that way the gamewill be rigged and the winner will be the one with a smarter PC.
So, if you find a place to bet on chess, i would like to recommend you to not place a bet.
If it's a tournament of chess (playing face to face like matches of magnus carlsen vs Ian Nepomniachtchi) then why not bet on a site but if it is a site where you are the player and you play against another player online then what you said is recommended to follow as I have experienced it myself when I played chess on facebook against another player but seems I can't beat that person and when I decided to use chess games in computer then it seems that the result is either draw, lose or win then that's how I found out that my enemy is cheating.
