[Rybka 2.2n2 32-bit (9s), M.Otero]
B41: Sicilian: Kan Variation: 5 c4
1.e4
c5
2.Nf3
a6
The O'kelly variation of the Sicilian. I should have played the Najdorf, since this opening is not recommended against strong master level players. 3.c4
Setting up the Maroczy bind. White makes it difficult for Black to make a freeing pawn break. 3...e6
4.Nc3
Qc7
5.d4
cxd4
6.Nxd4

7.Bd3
Last book move. 7...Nc6
I should have played 7...Bb5 pinning the c3 bishop which is what the opening recommends. 8.Nxc6

I wasn't sure whether to take back with ...bxc6 or with the Queen. Decided on taking with the Queen with hopes of having b7-b6 in the future. [8...bxc6

d6
I played this move in fear of 10.e5 with my f6 knight not having a good square to go to except g8. 10.Be3
Developing the bishop 10...Be7
Getting ready to castle. 11.Rc1
After this move my Queen began to feel vulernable. 11...0-0
Getting the King to safety. 12.Qf3
e5
Preventing e5, and closing up the h7-b1 diagonal to the White bishop.. Black has a new backward pawn: d6. Rybka doesn't like this move. Eval went from .27 in White's favor to .82. [12...Nd7
13.Qg3=
] 13.Bg5
Be6
I spent a lot of time on this move. I was torn between the aggressive 13...Bg4 attacking the Queen and the text move. I decided against Bg4 because the queen could go to 14.Qg3 and then if my f6 knight fell, the Queen would be ready to snap up the bishop. 14.Nd5
I wasn't expecting this from White. I figured I had no choice but to take the dangerous knight since 15.Ne7 was a Queen - King fork. I also looked at 14...Qd7, but then White had 15.Nb6 forking the my Queen and rook. 14...Bxd5
15.exd5
I thought White would take with the c-pawn, with a triple attack on my Queen.. White has the pair of bishops 15...Qe8
I looked at 15...Qa4, but 16.a3 refuted this move, and I felt my Queen would be vulnerable in the corner. Eval went from .60 to 1.60, this is the critical point in position. [>=15...Qd7!?
is an interesting alternative 16.Bf5
Qd8+/=
] 16.Bxf6+-
Bxf6
17.Qf5
Threatening mate on the next move with 18.Qh7#. 17...g6?
The only way to save the game cost me the bishop. The game is over at this point, but I decided to play to see how she would finish me off. [>=17...e4
I would have been able to take White's bishop in this variation. I considered this candidate, but not deep enough to show that I would have been able to take the bishop on the 5th ply. I should think as deep as possible in critical positions such as this. 18.Bxe4

Protecting the d-pawn. [18...Qd8

Launching a pawn storm to get rid of the King's defenses. [19.f4
makes it even easier for White 19...exf4
20.Rce1
Qa4+-
] 19...e4
An aggressive move, that was not well thought out (there wasn't much left). I thought of 19...h5, but then 20.g4 would be very problematic. [19...Rd7
20.f4+-
] 20.Rfe1
White quickly puts an end to any hopes. Black resigns. 1-0
