Annotated Chess Game 8108892 by Kyplor

My son's first win against me. I did not purposely make any bad moves, however, I made one that cost me the game.

1. e4 e5 2. Nb1c3 Ng8f6 3. Ng1f3 Nb8c6 4. Bf1c4 h6 5. d3 Bf8b4 6. Bc1d2 a6 7. a3 Bb4xc3 8. Bd2xc3 d6 9. h3 O-O 10. b4 b5 11. Bc4b3 Rf8e8 12. Bc3d2 Nc6d4 13. Nf3xd4 exd4 14. f3 d5 15. c3 dxc3 16. Bd2xc3 d4 17. Bc3d2 Nf6h5 18. O-O c6 19. g4 Nh5f6 20. Qd1c1 Bc8b7
? This is where Black lost the game. A better move would have been Bc8e6, attacking B at b3 and still preventing QxPc6. Black never recovered.
21. f4 Re8f8 22. e5 Nf6d5 23. f5 Nd5c3 24. Bd2xc3 dxc3 25. Qc1xc3 Qd8c7 26. d4 Rf8e8 27. Ra1e1 Kg8h8 28. f6
The game was over at this point, but I wanted to see if White could do the finishing moves.
