Yet another Najdorf Sicilian
6.Be2
But not the English Attack, notable with its f3, Be3, Qd2 complex
6...e5
A natural reaction. 5...a6 stole the Nb5 square.
7.Nb3
Be7
Black's structure is like the Sveshnikov (or Pelikan, but white is less able to manoeuver both of his knights to d5.
8.Bg5
Aiming to capture the Nf6 with the idea of Nd5, where, without the Nf6, the Nd5 can dominate the board.
8...Be6
The Nf6 will be exchanged, so black needs to place a piece in contact with d5.
9.Bxf6
Bxf6
10.Qd3
Having identified and fixed the d6-weakness, white prepares to attack it twice with the Qd3 and Rd1. The central pressure will also inhibit black's d5-pawn break.
10...Nc6
11.0-0-0
Be7
Defending d6 a second time.
