Re: can stockfish with book beat leela without book?

I have made the following experiment. Using the pgn Balsa25Top, Lc0 without book and BrainFish with Cerebellum light Book with best move activated.

Re: A repository for commonly used free computer chess apps, engines, opening books, and utilities

Very good idea! Thanks for share. There are so many good computer chess programs, test suites, engines, opening books, and utilities out there. Finding them is sometimes hard. Links are frequently dead-ends or the program is so old, the link is no longer valid. I've uploaded some of the common or ha...

Re: Lc0 ... the GOOD and the BAD

Lc0 and A0 has shown, that tactics are not so important at all. They have very small impact to rating obviously. Only important in tactical test suites :) .
