Yes, it does require less theory because white is very active and can develop smoothly while black in the early stages is often undeveloped and crampled. All the pitfalls are on the black side. In fact i have recenly switched to the open and i am very satisfyed with it; i tend to have exciting games (i am also scoring well) and i am now happy when my opponent plays 1...c5. The sicilian is a great defense, but handling it against the open is very difficult and requires a deep knowledge.
My "repertoire" (it's not like a have studyed many lines) is based on Bc4/O-O lines with an early f4-f5 break, but you can also choose something completely different such as the fashionable O-O-O lines if you like pawnstorm attacks. The open can be played in verious ways.
Stronger players on this forum and elsewhere keep telling us weaker player to stay away from playing sicilian as black because it's complex and difficult to understand with our limited experience.
Yet at the same time, we are often recommended to play open sicilian as white instead of the other alternatives.
Is the white side of the open sicilian easier to understand and play? Does it require less knowledge of theory than the black side? What are the general plans and ideas for white in the main variations?
