Stockfish Polyglot: Updated September, 15 2018

- Changelog: Tweak opposite colored bishops endgame scaling.

 

Due to the missing of this feature in the main release I have decided to create a Stockfish perfectly equal to the last beta version with the capability to use Polyglot books (aka .bin or BIN).

In order to do that I used the library polybook.h from Brainfish and merged with the Stockfish code.

Stockfish Polyglot comes with almost any architecture available, hence also for old 32bit operating systems like Windows XP, old machines, 64bit systems, standard machines, modern machines and power computers. It runs on both Windows and Linux.

 

WARNING: people using a 32bit system has reported that the program freezes just after reading the book lines... Since this feature is still experimental, please make a tournament engine vs engine on your computer before starting to play on other users online, just in case.
