No, I did not use watch mode when playing those games. I used
engine-engine. But I used watch mode to see the thought process of
Fritz5 when using maximum hash on my computer (only one engine loaded).
He considers b4 and Na5.

Concerning Nh5 in the first game. It is undestandable that Fritz5 never
considers this move. Actually, he still follows my theoretical line
here. Fritz5 begins thinking at the diagram position. I should have been
more clear on that point, sorry. I explained that from that actual
position Fritz5 should best play Bg4,e6,Be7,Ng7. Then he has a strong
position. The thing is that Fritz5 could not work out this plan but
instead played Bg7 and went directly into serious trouble. But this
diagram position is very hard for computers. I don't think any program
will find the best plan here. But probably no other top program will go
under as fast as Fritz5 in that game.

I'm sorry for not marking where the theory ended in that game.
