Subject: Test position Hydra-Nickel

Author: Uri Blass

It seems that Hydra is losing 2-0
It is probably relatively weak at long time control(Note that Nickel lost
against commercial chess engines so they seem to be better than hydra at long
time control)


Yace seems to have big problems to solve it(programs may solve it by luck but
It may be interesting if some program can see losing score for white after
the game move 42.Kf1 or even after the next move of the game 42...Ke4)
