9. Bc4 was a big mistake. I forgot that they can take on g2 if you play 9. Nb5 (Qxg2 10. Nc7+ Kd8 11. Bxg2) instead you could win the Queen. I considered just going for my own knight fork, but this is just losing. In the Endgame I was down 3 pawns, but for this I had huge piece activity and my opponent was just trying to trade down and save his extra pawns but after 0-0-0 Bxd4 it's all over and mate follows.
