it happened to Magnus Carlsen a few years ago in a blitz game. He put his opponent in check, his opponent, i guess by mistake, ignored the check and put Magnus in check, Magnus instantly moved his king out of check and his opponent called the arbiter and tried to claim a win.
even supergm like @Vidigt gujarathi makes a illegal move with magnus carslen
In my game (in a national game against a grandmaster!)
He made the move Rd8# but just because of just 10 or 20 seconds, my opponent did not notice it!
I later won that game!
@h2b2 what the link have you given us?
oops, @Kartikey_Tripathi , that was the wrong link. search for carlsen blitz controversy if you're interested. there are articles and videos of it.
Yes I have lichess.org/jTybdXPL/white
