Open Sicilian vs Dutch


Hmm, they are rather different. Why don't you tell us how you think they are similar?

The positions of the King and Queen introduce a strong anisotropy onto the chessboard.
1. ... c5 does not expose Black's King.
1. ... f5 does.

ok
against dutch-against sicilian-
as you can see, these 2 openings are not just mirror images of each other.

e4 counterpart, the Sicilian Defence, the Dutch is an aggressive and unbalancing opening, resulting in the lowest percentage of draws among the most common replies to 1. d4. Historically, White has tried many methods to exploit the kingside weaknesses, such as the Staunton Gambit.......
As mentioned, Dutch results in lowest number of draws....
I prefer Sicilian
