Goliath 1.1 K6-PR200, 13 MB hash

Pos 1 -  ----   (18:25)
Pos 2 -  0:28
Pos 3 -  4:23
Pos 4 -  1:17

I would expect that Pos1 (nice zugzwang-situation) cannot be solved
by programs using nullmove pruning without special zugzwang-detection.
So Fritz will not found the solution, even after hours. Correct ?
