In order to improve your chess skill, you need to play it with the higher 'rating' or 'rated' players more often.
Which one is correct?
Thank you!
You can use either.
A higher rating player
is the same as
A player of higher rating
here, 'rating' is a noun (and 'higher' is an adjective).
A higher rated player
is the same as
A player who is rated higher.
here, 'rated' is an adjective (and 'higher' is an adverb).
Your rating is your number score. You need to play higher-rated players to raise your rating. Beating a player with a higher rating will improve your score. In the chess world you will much more often here how to "beat higher-rated players" not "beat higher rating players"
