THE WAY TO GM


700-1000elo openings rules
For chess players around the 700-1000 Elo range, focusing on developing a solid foundation of opening principles and practical, easy-to-learn openings is more effective than memorizing complex variations. Key areas to focus on include controlling the center, developing pieces, castling early, and avoiding unnecessary pawn moves. Good opening choices for this level include the Italian Game and London System for White, and the King's Indian setup for Black.


The only and most reasonable meaning of GM would be Good Morning with that opening.
"Did you learn to play chess? Good Morning!"

Now I better unfollow this thread...
Isn't it hilarous when a 750 gives you advice to be a GM with an opening that hardly works after 750 Elo?
And "Follow for more content" is the cherry at top.
The way to Grand Master is a hard long path. But with practice it is possible.
