most important first. Importance is given by the size of the files divided by the number of times an endgames is seen in the database.

Code: Select all

A mistake no doubt

Perhaps the rating scale should not be linear, there is no question in my mind that krppkrp is the most important in the 7 man set , just as krpkr was the most important in the 5 man set,. It is the most important due to the "trickiness" and the frequency. I was doing some testing on EGTB's and many of then are solved by today's engines without any tablebases. krppkrp is the hardest for any engine to solve without egtb, based on over 30 years of observation ( and some testing ), intuition and some conjecture, ymmv.
would take a lot MORE testing than I did.
