Some programs see that taking g7 is a bad move because it weakens the white
position.
A typical zugzwang game :-))
In paderborn the zugzwang-queen was also travelling on b2 and tiger tried to
hunt it... The game itself can bring tears in your eyes, because it shows the
difference between search and knowledge very dramatically.
You cannot SUBSTITUTE "do not play Qxg7" by search.

Zarkov has king-safety terms...
It gives up Qxg7 arround 4' on my 200 Mhz machine.... Other programs, depending
on how much knowledge they have, and how many NPS they make, will also see it...

What has happened in the game ! what is your problem?!

>To estimate Gandalf we need the answer to the question.

no - to estimate gandalf you have to have made experience and you would have to
have seen games live. I have seen those games live, and i can guaranty you:
it knows about king-safety and these things (see paderborn tiger-gandalf)...
