The pin that kept on pinning

In round four of the Idaho Closed, I built up a small positional advantage as White in the Caro-Kann Classical and then won with a crushing tactic. It wasn't my most beautiful game of the tournament, but it was the most objectively accurate: I made no significant mistakes and only a couple suboptimal moves. Also, I was happy to avoid a letdown after my five-hour losing battle with my strongest-ever opponent, FM David Lucky.
