I recently wrote a post about this, I invite you to review it on my profile. I think on the subject, that everything is innocent until proven otherwise.

For me there is no player who is up to Magnus at the moment, the Norwegian has shown year after year what he is made of, however he is human and can make mistakes, anyone can beat him and that does not mean cheating.

Hopefully this problem will come to light soon and be resolved in the best way.
