Take Paul Morphy's famous opera game in Paris against the Duke of Brunswick and
Count Isouard.

1. e4 e5 2. Nf3 d6 3.d4 Bg4 4. dxe5 Bxf3 5. Qxf3 dxe5 6. Bc4 Nf6
7. Qb3 Qe7 8. Nc3 c6 9. Bg5 b5 10. Nxb5 cxb5 11. Bxb5+ Nbd7 12. O-O-O Rd8
13. Rxd7 Rxd7 14. Rd1 Qe6 15. Bxd7+ Nxd7 16. Qb8+ Nxb8 17. Rd8# 1-0

8. Nc3 is a very human move. Is it even possible for a computer (without being
in book) to even see a move like 8. Nc3 continuing development? Most computers
would just die to play 8. Bxf7+ instead I would imagine.
