What are the main strategic and tactical ideas behind the so-called Short variation in Advance Caro-Kann? I mean this line:
[FEN ""] 1. e4 c6 2. d4 d5 3. e5 Bf5 4. Nf3 e6 5. Be2
Isn't White's position a bit passive, and furthermore with Black's Bishop already developed in f5? Why do GMs play this line?
