It is not about book or movie, it is about my game last Monday. My opponent was a guy to whom I lost a few times with Black, this time I had White. I played Moscow variation against his Sicilian and he decided to close the center. He was moving his pawns on the both parts of the board and I thought that I need to do something.

So I played 20. a4 with the idea of getting c4 square for my knight. It is the move that computer suggests, with an equal play. He accepted the sacrifice, then started to move his knight in order to exchange it on c4. I thought that if I will exchange queens it would delay that. It was a mistake, computer evaluates it as -1.

I had to switch to defense. I made a big mistake when I played 34. Ke2, the best was Ra1 and if 34… Rb4 then 35. Ke1. Then 35. Kd2 lost the game because he played 35… a3 and forced the transition into an endgame that was lost for me.
