This is White's main move against the Najdorf. Whatever his reply Black has no option but to go head first into razor-sharp positions (Emms).

This is a rare but natural move for White.

And Black has a better ending due to White's inferior pawn structure.]
8...Qc7
The idea behind ...Qc7 is to begin queenside operations early with ...b7-b5, but without allowing e4-e5. But in this case either ...0-0 or ...Nxe4 would have been better according to Rybka.

11...h6
Posing the question to the annoying bishop.
12.Bxf6
I wasn't sure whether to take with the bishop or the knight. I ended up taking with the knight so that I can put pressure on e4, but Rybka prefers ...Bxf6 -.47 to -.27.

Putting pressure on e4. ...B4 might have been the better move forcing the white knight back to b1.

Losing the initiative by releasing the pressure. Also the take back with cxd3 opens the c-file for the White rook allowing it to attack the Black Queen. [Rybka 2.3.2a 32-bit : 18...Rac8

I should not have placed my queen in such a vulnerable position. Even with minimal calculation I should have seen the pattern where the situation could be created by White where a check with the knight would lead me to lose my Queen. [Rybka 2.3.2a 32-bit : 24...Qb4
