Out of book
8. Nf3d2 Bd7c6 9. Nc3d5 Bc6xd5 10. cxd5 Nb8d7 11. Nd2c4 Nf6h5
?! Not sure what black was thinking here
12. e4
Opens attack for Qxh4
12... Nd7b8
?? Probably that move cost the game for black. Knight at h5 is unprotected
13. Qd1xh5 c6 14. Qh5g4
?! Better is Ne3 to bring over the knight from the other side and put pressure on the king. However pawn at g7 is pinned and pawn at h6 is threatened
14... Kg8h8
Unpins g7
15. Nc4e3 Be7g5 16. Ne3f5 cxd5 17. exd5 Kh8h7
?? Major blunder for black. Better is 16...g6 18.Nxh6 Bxc1 19Raxc1 Nd7
18. h4
! The best move for white
18... Bg5f6 19. Bg2e4 Kh7h8
?? Game over for sure. Can delay the inevitable with 19...g6 20.h5 g5 21.Nxd6+ Kg7
20. Qg4h5 Kh8g8
Walks into a Mate in 6
