There is a lot of consideration and complexity.
Even just picking which one to play is a basket of marbles. Then you have to consider main lines, open Sicilians, the bulk of anti-Sicilians and transpositions. You really have to carefully map it out for long term gains. It’s not for everyone.
I went thru a recent adaptation with online chess by switching over to 2. e6 from d6 for a variety of reasons, I am still building up the feel, intuition and familiarity despite experiencing immediate success.
hello I created this forum to talk about the Sicilian defense because this part is played at all levels so it would be interesting to see what you think about it
