Why do you want to avoid the Chelyabinsk/ Sveshnikov?
It's a very sound and reliable opening, while the mainlines of the Kalashnikov are quite passive for black.
The only reason could be the theoretical bulk... but this is more or less unavoidable when playing mainline sicilians.
I was wondering what the different ways to avoid the Sicilian Sveshnikov from the Kalashnikov were. I'm looking for something aggressive, even if a little positionally suspect. Thanks in advance,
