as soon as you reach 2100 and keep studying chess you are just wasting your time. there is nothing to learn really except memorizing opening lines up to move 30 like in the sicilian. what strikes me is that some people enjoy it.
WRONG!
You need to get away from the beginner writers (Silman, Alburt, Seiriwan) and read the more advanced stuff.
Many of the books by Quality Chess like:
- The Grandmaster Preparation Series
- Advanced Chess Tactics
- Chess Lessons
- Mating the Castled King
And many of the middlegame books by New In Chess like:
- Liquidation on the Chessboard
Along with DEEPLY annotated games of MODERN GMs. Ones like Garry Kasparov on Garry Kasparov.
Also, subscribing to things like Informant or the Chess Evolution Weekly Newsletter (CEWN).
Also, Opening books beyond the Starting Out or Move by Move series.
Also, when it comes to studying openings, look for books that are "OBJECTIVE", like the Chess Developments Series (i.e. Chess Developments: Sicilian Najdorf 6.Bg5). This way, you are looking at various lines from an objective standpoint and not being driven down a narrow path from one side only. Repertoire books say "This is what we are going to play, and I'll cover all of White's alternatives".
Instead, a book like the one mentioned above, if you study it, Black makes up his own mind whether to play 6...Nbd7, the Polugaevsky, the Classical, the Poisoned Pawn, the Delayed Poisoned Pawn, etc, rather than having someone else make that decision for you. This way, you play what you are comfortable with, not whatever one GM says to play.
I'm playing at a more or less 2000 rating in tournaments, and my coach tells me that my understanding is 2100+. My question is, what is there left to learn after this?
I've already read all of Silman's books, Jacob Aagard's, and all the books that are constantly being recommended for sub 1800 players.
So what is there to learn now? What books are for a level of 2100?
