I do not think that knowledge is the reason for chess system tal's failure.
I do not think that knowledge is a reason not to search deeper because knowledge
can help for better pruning rules.

chess system tal has simply bugs.

Thorsten reported bug in null move pruning and I remember that he suggested a
style without null move pruning for fast computers).

I also rememebr another bug when chess system tal believed wrong mate in one of
thorsten's tournament.

I believe that the programmer simply decided to leave chess for other games.
