"Secrets of Grandmaster Play" by Nunn and Griffiths.

8. Bg5 hxg3 9. Nxg3 Nd4 10. Nh5 Ne6 11. Nxg7+ Nxg7 12. Nd5 Nxd5 13. Bxd8

25. Qxe3 Bh3 26. Kf1 Bxg2+ 27. Ke2 c5 28. Qd2 b6 29. Qc3 Rf4 30. Qa3 a5
31. Qb3 Bh3 32. f3 Rg2+ 33. Ke3 Bg4 0-1

How do programs eval white's chances after Black's move 12 ... Nxd5
after about a 10 minute think? Also if you play over this game in analysis
mode, check your program's choice for black on move 16.
Will they go for the material with 16 ... Nxg2 17.Kxg2 Bh3+ and Bxf1?
