Cfish: Updated December, 2 2018

- Changelog: Updated to "Replace the PassedDanger array by an equation".

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.

One of the best engine to analyze games, very versatile.

Test 46 games at 1m + 1s
Cfish 280319 – Stockfish 240419 without book.bin: +4 =36 -6
Windows 10 PRO Procesor: I7-4790 CPU 3.60 GHz; RAM: 32.0 GB; System type: 64-bit. Both engines are BMI2
Values is roughly equal, but I prefer Cfish to corespondence chess, because Cfish uses Book.bin and thus becomes Better Stockfish.

Bin books are not made for correspondence chess, unless you're using SCiD with its Book Tune function or Droidfish. You may want to try CTG if you have Fritz or ABK if you have Arena.

I'm sorry, I do chess analysis only on Fritz 15, bought from chessbse. I tried to work on the Arena, but I did not like it and I quit quickly. With DCID I do not know how to work, and Droidfish is an android and it does not help me. In conclusion, I only use Book.ctg. I did not know that book.bin does not help me with infinite analysis.
Thank you very much for clarifications!
