The first (Nxg6) is difficult for SpiderChess. It takes 4 minutes and
24 seconds on my fast pc (AMD 2000 XP).
The engine is obviously sidetracted by the other good move in this
position (Ne3xf5) which it finds in 3 seconds.

2 and 3 are easier. Nxf5 takes 2 seconds and Qxf5+ comes instantly.
I didn't clear the hashtables inbetween. It would probably take longer
if I did.

Cheers
Martin
