yace could not see clear advantage for white even 5 plies after
the root position so I suspected that maybe rebel was wrong in it's line
but it seems that yace after learning can see that
Rh3 is leading to a clear advantage for white so the reason of
Rebel was good enough and maybe Rebel outsearched yace by more than 5 plies.
