1.e4
c5
The Sicilian
2.Nf3
Active lines require Nf3 and d4
2...Nc6
Not my personal favorite, but solid. IN Hedgehog lines, the Nc6 can wind up blocking the c-file and the a8-h1 diagonal
3.d4
cxd4
4.Nxd4
Nf6
Attacking the e-pawn and, by forcing Nc3, preventing c4
5.Nc3
d6
...e7-e5 is the Sveshnikov, or Pelikan.
6.f4
Alterantives are Bg5 (the Richter-Rauser) and Bc4 (the Sozin).
6...e6
Solid defense, preparing Be7 and watching the key d5 and f5 squares
7.Be2
To support g4 and often to place the Be2-f3
7...Be7
8.Bf3
Bd7
Solid. If Nxc6 Bxc6, and black can now play Nxd4 Bc6
9.Nde2
Qb6
Inhibiting the development of the Bc1 and preventing 0-0.
10.b3
To develop the Bc1, but weakening c3 and the c-file.
10...a6
The Qb6 has done its job. a6 prepares Qc7
11.a3
Rc8
Black's usual counter play down the c-file
12.Qd3
The queen will be awkward here, vulnerable to attack by Ne5
12...Qc7
13.g4
Diagram Aggressive, but unwarranted. Black responds with even more aggression
13...g5!
Offering a pawn for the e5 square.
14.h4

h5
16.g5
Ng4
17.Bxg4
Otherwise Nce5 with a positional stranglehold
17...hxg4
18.Kf2
Ne5
A great square, and a common response to a Bf4, but why not just take the Ne5?
19.Bxe5
dxe5
The doubled pawns are very useful for black. They inhibit all counterplay, control key central squares, and the Be7 can now repost on d4
20.Kg3
Bc5
21.Kxg4
Bd4
Undermining white's defensive stand on the c-file.
