Anti-cheating: should there be a limit to a number of toilet breaks per game per player?

No, there shouldn't and if you live to be 80 you will probably understand why. A few years ago in a tournament where I was one of the arbiters a 16 year old boy was playing an old guy in his 80's in ...

If Hans Niemann is cheating, how?

The simple answer is that he is not cheating. Magnus just played badly. Had Magnus had proof he would have presented it at least to the arbiter. He didn't. The chief arbiter, Chris Bird agrees with me....

If Hans Niemann is cheating, how?

I agree with Brian Towers, that the most likely scenario is that Hans didn't cheat (despite his weird behaviour in the interviews), as indicated by an engine check of the game. How would he have done ...

lichess vs chesscom players

Like I find it easier to beat a 1900 player on lichess than a 1800 on chesscom which is insane! Why is that insane? According to one site, an 1800 blitz rating on chess.com is about equivalent to a ...

Did Hans Berliner win the world ICCF championship using computer help?

Short of asking a deceased man, I would say that the answer is "no way". He won the 5th World Correspondence Chess Championship in 1965. Computer chess, if it existed at all, was not strong at all. ...

Chess positions that are easy for humans but near impossible or confusing for computers

One way to fool some computers is to give them a fortress and then offer material to trick them into opening the portcullis. For example: [Title "White to draw"] [FEN "8/8/pr1k4/...
