Hi Ed, even though we have never talked to each other, I know your chess projects, which are useful and interesting.
I admit I don't know anything about the Polyglot format, but it seems to me a not too complicated and useful modification. You are proposing to change this code: https://sourceforge.net/p/scid/code/ci/master/tree/src/polyglot/book.cpp#l683 entry-> n would become entry-> score (but n is unsigned, how did you encode the negative values?) entry-> sum would become entry-> depth (one byte) and the last byte would be an index into an array of const char*. It's correct? > Il 17/03/2021 07:41 Ed Schroder via Scid-users > <scid-users@lists.sourceforge.net> ha scritto: > > > Hello Fulvio, > > Send you a PM at Talkchess but it remained unseen by you.
