Editor's choice: best engine for chess analysis.

 

Cfish: Updated June, 15 2019

 

For Windows only this time. My disk is busy with other projects so I had to delete the Linux virtual machine.

 

- Changelog: Updated to "Simplify SEE Pruning".

 

Why choosing Cfish for chess analysis:

Cfish is absolutely the best program for chess analysis; this morning I had the oppportunity to test it on an AMD ThreadRipper 2990WX in the Fritz Cloud Room: its coherence is above any other chess program. In other words it shows almost always the correct move (after depth 30 or the like) with the proper position score, while programs like the original Stockfish set a positive score, suggest a move, and when the move is done the score suddendly drops down. If you want to avoid alot of frustration you should use Cfish for your analysis.

 

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.
