c5
The Sicilian Defense
2.Nf3
d6
3.d4
cxd4
4.Nxd4
Nf6
Nf6 attacks the e-pawn
5.Nc3
Defending the pawn. The sequence prohibits c2-c4 and the Maroczy bind (pawns on c4 and e4).
5...a6
The Najdorf variation.
6.Bg5
Fischer tried many different moves here, but used mostly Bc4 and Bg5
6...e6

Qc7
9.0-0-0
All standard stuff
9...Nbd7
10.f5
More common is g2-g4, Bxf6 and g5
10...e5
A normal reaction. Black creates a hole on d5, but the f5-pawn now blocks the normal Nf5
11.Nb3
b5
idea b4 and Bb7 with pressure upon the fixed e4-pawn.
12.a3
To prevent b4, but a3 weakens the queenside.
12...Bb7
Two attacks upon e4
13.h4
Rc8
Delaying ...0-0, which would give white a target for the attack. Black is preparing the ...d5 break and stops Nd5 (Qxc2#)
14.Bd3
Over-protecting both c2 and e4
14...h5!
A lovely move, stopping g2-g4 and, in fact, stealing the g4 square for the Nf6
15.Kb1
Nb6
Idea Nc4xb2 and Qxc3
16.Nd2
Trying to stop Nc4
16...Ng4
Trading the bad Be7 for white's good Bg5
