Perhaps a hidden grandmaster?

Can anyone with a premium account analyse the games of this person? In my opinion there are several games played at an extremely high level, so perhaps this is the hidden account of a grandmaster?

Thanks in advance

I don't think so, if he were a Grandmaster he wouldn't be stuck at around 1700 blitz after 500 games

you're right, but some games are really good, perhaps it's a shared account with someone very strong using it from time to time?

If that's the case it's against the guidelines

yeah but it's an account from 2018, so I'm guessing that chess com would already detected if something was wrong?
