Go up one level in this thread
This time really with krpkrp. A very surprising result. Without TBs, Rg1 was
found at depth 14, with a good collection of TBs, Rg1 was only found at depth
18. It might be interesting to see, if other engines have a similar behaviour.
It is not the first time, I see my engine needing more depth with TBs. It could
just be coincidence, but I have the feeling it isn't. It should be interesting,
to investigate the real causes. Perhaps this position is a good study object
(with such a huge difference in solving depth). Unfortunately, the search tree
will be too big, to dump and investigate really carefully. Regards,
Dieter
