Initially I was concerned with 16. exd6 exd6 17. Rxe8+ Qxe8, removing my queen from the defense of the d pawn. However White can't play 18. Bxd6 because I have 18...cxd4 attacking his pinned knight on c3. My tactical threat was more powerful then his. He can win my pawn, but I'm going to win his knight and have a very annoying passed pawn deep in his territory.
After 16. exd6 exd6 17. Rxe8+ Qxe8, he opted to play 18. Qa3, breaking the pin and threatening my bishop on a6.
Here's the entire game.
