Yes Crafty can find this line:
(4) 15-> 57:46 3.15 1. Nxh7 Kxh7 2. Rxf7 Rxf7 3. Qh5+ Kg8
4. Bxg6 Be6 5. Qh7+ Kf8 6. Bh6 Ke8
7. Qxg7 a5 8. Rf1 axb4 9. Bxf7+ Bxf7
10. Qxf7+ Kd8 11. Qf8+ Kd7
I want to break this line after because it's not really forced after it:
1. Nxh7 Kxh7 2.Rxf7 Rxf7 3.Qh5+ Kg8 4.Bxg6 Be6 5.Qh7+ Kf8 6.Bh6 Ke8 7.Qxg7
But from here it's +5.00 for White according to Deep Fritz

This line is something better yes, because Na6 is worth +4.06. So Nxh7 seems to
be a clear win for white.
