A Knight sacrifice to open an important Diagonal


Please look at the following interesting position:

Well, what might have been White`s thoughts? Perhaps: "This pawn on e4. what would I give if it wouldn`t be there!"

This probably the point when we change the stream of our thoughts with some regrets: "No way! The e4-pawn is blockaded. I will not waste my time! What can I do on queen side?"

But in this game kept searching for a possibility to free the diagonal for the bishop on b1. And he found it! He sacrificed his knight


A happy Easter time:
