Why? I find the PVs rather convincing. To me it looks, they are correct for at
least 8 plies (Fritz only shows 8 plies, I did not look at the later plies of
Tiger, but at least a1Q+ Kxa1 seems winning). Perhaps the scores are not
convincing, the PVs are - I think.

My engine would probably not need years - but many hours.

Dieter
