Junior 9's openings book calls this line '=' but on a lecture on the Grand Prix Attack, GM Roman Dzindzichaschvili calls this line won for white and shows it in a couple of different lines. IM David Vigorito says that d6 in this position instead of e6 leaves black with a desirable position.] 6.0-0

Since white has not played h3, Black's plan is to take the knight off. 8.h3

Black has some pressure on the b-file, and white does not seem to have an attack, although he is up a pawn. I felt quite happy about my position here. It is an almost Benko-Gambit like plan. 18.c4
White's bishop is a bit like a big pawn here, although it can be said that it will be good in an endgame and can have a potential if the Queenside is opened up. Fritz 9 prefers Bc4 to this. [18.Bc4

And this is another equal but unclear position.] 18...e6
I am not sure if this is best, but it doesnt put me in too much danger and opens up a defense on f7 by way of the queen on b7. My move also prepares a future d5 or f5. 19.Bg5 is comfortably met by... Nh7 and the bishop is forced to move back. 19.Qh4

This position is certainly about equal. Even Fritz 9, which, like all engines values extra material, does not feel that white is winning. 32.Kg3?
Diagram Now Fritz says Black is winning. At the same time this is quite an understandable move. White is tied down on the h and g- files as he cant move his rook because the h-pawn falls, and if he can't move the rook then he has no way to play for a win. 32...Nxg5

I felt that my ending might be a bit better here. Fritz 9's evaluation is similar to mine. It says the position is 0.55 pawns better for me . Probably not enough to win though... 37...Nd3

=/+ 0.60 according to Fritz9 - Here I felt that the position was equal. 39.Bxd4+

And now Fritz says that after Bxe5+ the position is equal. To keep my advantage, I wouldve had to play Bf6, which, with hindsight was obviously better, but during the game I had this hallucination that my knight would never get out. [39...Bf6

Is rated by the Junior 10 engine as + 0.38 (after about a minute of infinite analysis) in black's favor. Black probably has just enough activity to draw this ending. (LT).] 40.Kf4
I thought my opponent's plan was Bxe5+ followed by Kxe5 which of course loses to Bf6+. However, he had planned something much more annoying. 40...Bxh4
41.c5!
A very nice move. White has managed to complicate things enough that he might even win if black isn't careful. 41...Bf6
Basically forced. Amazingly Fritz 9 still feels that I am winning ( =+ 0.18) ( hardly an advantage!) 42.cxd6

so that it this knight can go back to e6 to defend d8. I was scared of playing Nb2 because I felt it would be hard to bring my knight back to stop the pawn. Fritz thinks Nb2 is as good as my move. Both leave the evaluation at = 0.00. 45.Ra2

A draw was agreed here. Fritz wouldn't have taken it if he were black. He would play Nf4 +, after which black will win white's d-pawn. However the position is probably still drawn, so even if I had seen this move, the result probably wouldn't have been different. [50.Kd5

And white should be able to hold this quite easily. (Well, the Junior 10 engine likes this position by +1.19 for black, so if it was reachable, and black is relaxed it is worth playing on for the win. (LT).] 1/2-1/2
