the.com/grand master

Chess for people who've made peace with having no hobbies left to master.

means An official top-tier title given to the best chess players in the world, earned through tournament performance and ratings, not just handed out for being pretty good.

from From 'grand' (Latin grandis, great/large) plus 'master' (Latin magister, one with authority or expertise). The chess title itself is the modern layer: informal use of 'grandmaster' for elite players grew in the early 20th century, and the title was formalized by FIDE, the international chess federation, in 1950, turning a casual honorific into an official rank with criteria attached.
