I think I had him, but I messed up
How about 13... e4 14. Nd2- Nd6 (15. Sdxe4-Sxe4 16.Sxe4- Lxa1)?
With the idea of f5.
I have a pawn on d6. Do you mean 14...Ncd7? During that time I was looking at that diagonal and that move (e4), but I was concerned that that would weaken my pawn so I wanted to play f5 first, which didn't work since it weakened my position.
