Cfish: Updated Avril, 19 2021.

For Windows 64-bit and Linux, NO WINDOWS 32-BIT, ANDROID OR MACOS!

- Changelog: Updated to "Removed advanced_pawn_push()".

The Windows executables works by default only with the file nn-62ef826d1a6d.nnue in the same directory.

Compiled with MSYS2 and MinGW for Windows and GCC for Linux.

CFish, a port of Stockfish written in plain C by Ronald de Man, first published on GitHub in July 2016. Possibly inspired by the asmFish project to speed up Stockfish using a programming language closer to the machine, the purpose of CFish is to explore possible optimization issues of C versus C++ compilers.

Its reliablity is unique, Cfish is the best chess program even in short time games other than being the best choice for chess analysis.
