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:
Bubbles09 vs. NyLsel (1750)
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!
