The power of being prepared or knowing your openings

Watching the candidates where such beatiful games are being played, and specially astonished after some games like Firouza vs Nakamura and Nakamura vs Ding where Black managed both times to survive a tricky preparation at the same times in the realm of the mortals  I was playing myself a game where I was in the preparation side of the game... I want to share this game where the opponent walk right into a position I played just a couple of months ago and I was able to remember all the little details to win the game.

Hope you enjoy the game

Good chess!
