Caro-Kann Advance Variation, 3...Na6

In this game I played White. In the opening my plan was to gain kingside space and keep the center closed so that I can attack on the kingside. Black kept his king in the center for a long time, and I decided to try to exploit that by opening lines and sacrificing a pawn in order to create attacking chances, although there were slower but more reliable ways to gradually develop the game. I got into a worse position that was nevertheless sharp and offered different tactical possibilities. Black misplayed some moves too, returned the pawn and after simplification the game seemed to be equal. Then Black made an oversight and lost his queen, and I won. Anyway, both sides had their chances throughout the game and the play was interesting, as many positions required careful analysis.
