Open Sicilian lines

Sort:
Skakmati

Forgive me this basic question: there are several lines that use 3.d4 (below). Are all of these classified as "Open Sicilian's" ?

B41-43 Kan
B45-49 Taimanov
B60-69 Richter-Rauzer
B70-79 Dragon Classical
B90-99 Najdorf

(I probably missed some...??)

Any Sicilian which goes 1. e4 c5 2. Nf3 and then 3. d4 cxd4 is an open Sicilian since the center has been opened with a pawn exchange.

The variations you listed are all variations of the open sicilian.
