please post the relevant position

 which can not be found by any computer, even not by ZUGZWANG
>(from Paderborn) or by Deep Blue (from Yorktown Heights).


How do you know that the move cannot be found by any computer?

I will never say something like that because I believe that every good move can
be found by a program if the program is good enough to find it.

There are moves that I do not know about computers who can find them(for example
Shirov's move Bh3 but I cannot be sure that no computer can find it.

I also cannot be sure that a move cannot be found by Zugzwang or by Deep blue
because I cannot test these machines.

I do not know why do you say even by Zugzwang cannot find the defensive moves
because there is no evidence that Zugzwang is better than commercial programs.
