The variation is not defined yet...
Wolf variation : first time i heard it but anyway as I said, the line is not defined yet, it is just a transpositional move.
Can become a KIA, a Closed sicilian, a big clamp, and even a Botvinnik English...
I have high opinion of closed sicilian, while the others are reliable too : but white doesn't play alone so according to black's set up, one of the 4 variations i gave is better or worse.

Thanks for this insight. 
Let me add something IMPoucin doesn't know.
2...d6 is the Sheep defense , considered too risky against the Wolf variation.
You welcome!
I guess that Lamb defense sounds better. 
Wolf variation was known in Germany as the Adolf Hitler variation. Before WW2.
You are so stupid, Yigor!
LMAO 
Coming from U, I take it as a compliment! 
Please tell me your opinion about it:
According to chesstempo's database, it was first practised by Siegfried Wolf in the period 1921-35.
