Given that in GM Simon William's book The Killer Dutch, Williams says that the Sicilian and the Dutch are mirror images of each other, as Williams states "If you look at the first move, you can see that the two openings are similar, due to the fact the initial pawn structures of both openings are actually mirror images of each other." (Williams, 32) What Sicilian Defence variation has the most similarity to the Dutch? In the sense of pawn structures, middlegame plans, and strategic ideas? From what I observe it seems to me like the Scheveningen is similar to the classical variation of the Dutch.
Which variation do you think is most similar?
