How much time does your program need to avoid Nxg3?

Here is Junior7's analysis on p200 after some learning
It has no problem to avoid Ng3 after  learning 18...Nxg3 19.hxg3 Bxg3 20.f4 Qh4
21.Rf3 Qh2+ 22.Kf1.

In the game of the match that a link for it is posted elsewhere
Shredder5.32 could not avoid 18...Nxg3 and lost against Fritz7
