Fighting a "solid" Sicilian line
This is a well-known Sicilian Kan tabiya, with over 100 master games played from it. I happened to meet it in a correspondence game a few months ago, and I was quite puzzled about the way white should handle it.
Question no.1: How do you evaluate the position?
Question no.2: Which is the best move for white? (explanations and planning are welcome).
