After 6...Bg4, White should be able to play 7.Qxb7. Black could do better with 6...h6 or 6...Nc6.
7.f3 Bc8 would be better than 7...Be6. Now Black should have played 8.Nxe6 and 9.Qxb7.
8..Bc8 still looks best.
11...Qd7, then 12...Rb8 seems better.
Instead of 15.c4, perhaps 15.O-O.
16...dxc4 should have lost. 16...Nf6 was best.
Now White should have played 17.gxh5, winning a piece. 17.Nxc4?? loses to 17...Nc2+, winning the queen.
Yes, OK, even though I did win the game, I think there could be a few points raised about the way I played, but I can't seem to find them, so I was hoping that you could help point them out.
