Need a bit of help with the Opening

Hello everybody,

My first post here. A bit about myself: I am fairly new to chess and theory but not a total noob. :)

This position arose after a Najdorf. I am playing white. How should I proceed? If possible please critique my moves thus far. I don't know any theory beyond the open position i.e e4 c5, NF3 d6, d4 cxd4, Nxd4 ..., Nc3

Edit#

I want to add that this is a game against a computer, not against a human opponent. I would not ask for help otherwise <should've read the rules first! )

this is a good time to advertise: www.chess.com/explorer :)

Also (as Game Explorer will tell you), this is not a Najdorf.

In a Najdorf, Black plays 2...d6, 4...Nf6 and 5...a6. This (with 2...e6 and 4...a6) is called the Kan.

Thanks man. I assumed that a6 is always a Najdorf signature. But what is your take on my current position? :)

It was not a Najdorf.
