I had a game with a stronger opponent and have to prepare persistently. My Opening preparation is pretty exhausting but I needed to train methodically. I won the game convincingly with a fine sacrifice at move 15! Here, I demonstrate how to gain advantage if you occupy the key-squares of your pieces.

Here's the game:

Notes: White's problem is lack of counterplay and space for it's pieces. Black gain the advantage by finding the key squares 16...Nd4 17...Nxf3+ and 18...Bh3

Please comment for your suggestions in my game. Thanks!

Feel free from posting your comments... Thanks!

White made one or two weak moves and KABOOM !! That was a High-Caliber combination thanks for posting.    lol

your 5 and 7 is backwards

Your commentary reminds me of Silman. 

mitharris: who is Silman? :)

Yup, White made a mistake, so I take the opportunity to gain advantage in that situation. Thanks

What do you mean that my 5 and 7 is backwards?

c3 is not necessary for d4 white should've played more agressive. Also Nf6 white should've castled, and not have played the passive d3

c3 is particularly not an ambitious move and ; playing c3 is the closed variation of spanish game. White can delay the castle here by playing Nbd2, Nf1, and Ng3. :)

After 17...Nxf3+ White could have tried 18.Nxf3 where he ends up with rook + bishop vs. queen + pawn ; this should be lost but Black has to prove it !

(whereas 18.gxf3?? loses right away).

Many other mistakes from White, also from a positional point of view.

The mistakes had been played that's why I take the opportunity to win the game.. 

@ nyLsel : in the side line you give in your previous post, why would Black give up his bishop ? 6...Qh4 retains the bishop (instead of 6...Qf4)

you play boldy and nicely! :)

What???? :)
