V & M Platov study
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

No, I have the 6 man files. I am sure you can replicate it with your copy if you have them. I think I used 11 threads.Jouni wrote:Mate in 72 is record for SF! You have DTM syzygy already?
For whatever reason, SF solves this one even faster than MateFinder

The mate in 72 must be a case where the TT value from a higher depth leaked into the PV. Although SF "in principle" does not return TT values in the PV, its qsearch in fact does.
The position is mate in 34 or less:

Mate in 72 is some kind of bug I suppose? I get also long mates with SF, but never over #64.
