Those my tablebases are not working with new engine Fritz 17, can you to help to me? Thanks in advance.
My guess is that Ginkgo(Fritz17) only supports Syzygy tablebases.
I've Syzygy too, but nothing is working with Fritz 17
Unloading and reloading Fritz 17 engine might help.

Re: Fritz 17

Why would you need to buy one ? Long answer: This is unrelated to Fat Fritz, Stockfish has been #1 chess engine for years, and it has been free, yet people keepe buying other commercial chess engines like Komodo or Fritz. They need to buy it because others need to sell them. My computer is 9 years ...
