How useful is it to know 15 moves of theory in multiple variations of "theory heavy" openings if you don't understand why the key moves are important to play and how to proceed if your opponent deviates from the main line?
The reason why beginners are encouraged to avoid certain openings are because there are numerous plans to learn (English opening), a lot of memorization is required to survive the opening (Dutch via 1.d4 f5 move order), or it is easy for the opponent to avoid (Benko Gambit).
Starting off, it is better to focus on the basics first (Following opening principles, Tactical skills and basic positional understanding) so that when a player decides to implement those "theory-heavy" openings, they will be in a better position to play it well from the start and their game as a whole won't suffer.
Hey all,
I often see ideas like, "Beginners cannot play X opening (i.e. Najdorf Sicilian) due to being too theory heavy"
Why is this? If a 600 elo wants to play the Najdorf, it's not like their 600 elo opponent is going to know 15 moves of theory.
A common idea that has continued to confuse me a bit, thanks!!
