Cheat detect

Recently I was playing my 3rd consecutive classical game with my opponent, during the early stages of the 3rd game, I was immediately given the win after it said "Cheat Detected, White is victorious." My opponent said that this was due to the analysis board being open? Is this something that is a bug or was actual assistance being used unfairly? Any clarification would be appreciated. Thanks, Graham

Hi

I'm not sure what happened, but a 600 pt rating difference between his classical and blitz rating is somewhat suspicious.

I agree, this guy is clearly a cheater. As Unthinkabl3 pointed out, look at the rating difference between blitz and classical.

This is what I initially thought, I pointed out the disparities between ratings which was met with the response akin to "I don't take it seriously/don't try. This was added after he claimed his blitz rating was so much lower due to lack of speed. I don't take blitz seriously, most people on here don't, disparities that large are very rare. I appreciate the feedback though guys and will report the individual to see if he indeed used assistance.

It means that your opponent used an analysis board, with stockfish turned on, to get an evaluation of the game current position.
Lichess then ends the game and shames the cheater.

and the cheater's acc is closed
