1766 rated master?
NEW TITLE: Master???

yeah Idk how to achieve that title
You can't. I think the only other account with that is @coach
There is also the chess Grandmaster rated 1415...
If you are talking FIDE ratings then the lowest rated FIDE GM is in the 1900s and the five lowest rated FIDE WGM are in the 1800s.
There are two ways that can happen. A player can become a GM and then have a rating loss due to aging. Or a player in the past could get a direct title due to a good result in certain FIDE events (in the past, since then FIDE has added a minimum rating requirement for a direct title that is 200 points less than the normal rating requirement).
For example, in "The Queen of Katwe" the player was rated 1686 when awarded the WCM title. It normally has a minimum rating requirement of 2000 and currently the direct title still has a minimum rating requirement of 1800 but back in 2012 there was no minimum for a direct title.
The player @samayraina is a titled player that is labelled as "master" which is not a REAL chess title! How do you apply for this title and what are the requirements of this title??
