This engine is a Stockfish derivative, and made primarily for analyzing chess games. The search is a bit slower than Stockfish developer but more accurate. In my EN test 2022, the engine solves 116 out of 120 positions with 75s. The latest NNUE network from 010123 and most Stockfish patches up to 010123 are implemented. It goes without saying that this engine is no Blitz monster. However, the engine is very well suited for games with longer time controls. The engine has no special features like self learning, I wanted a pure analysis tool. The photo shows the settings I use to play blitz and rapid chess games on PlayChess.com.

Thanks for this engine !
It set records in my HTC (108 positions).
After 9 runs (5 minutes, 16 threads AMD 5960x@4Ghz) : average 103.2/108

Difference between Stockfish dev and Charisma Saphir:

Just because Stockfish is faster doesn't make it better. Above a certain search depth, the faster engine will not find better moves. We see that on the server every day! An engine with only 4 cores is deep enough to be able to stand up to 64 cores. Thanks be NNUE! It is more important not to miss anything than to calculate too deeply.

In my EN test 2022, Charisma Saphir manages 115 solutions (Stockfish dev 110).

What's the differences with Saphir and Gold and Diamond ?

[Eduard]

Diamond has a fast search. Gold has a slow search. Saphir is in between.

26 Jan 2023: Charisma Light 1.0 released!

Charisma light 1.0 is a super powerful UCI engine based on Stockfish dev. Charisma Light has an active playing style, and is excellent for analysis, as well as blitz and rapid chess. I have renounced all features to keep a pure search code. Learning files are useless in my opinion when playing with good opening books. A learning file that was created with older engine versions also prevents the development of a newer and more modern engine version! In addition, the learning file throttles the speed of the engine. I always use GUI opening books, so I don't need polyglot book support. However, MinimumThinkingTime is important on online servers when playing without bonus time. I recommend a value of 100 (100ms). In my 2022 EN test, the engine scored 115 out of 120 points. Download textfile on my homepage.

No virus. I scanned the entire folder and all files:

I had no problems with the download from pixeldrain.

Kaspersky and BitDefender both show the folder clean.

Just because Stockfish is faster doesn't make it better. Above a certain search depth, the faster engine will not find better moves. We see that on the server every day! An engine with only 4 cores is deep enough to be able to stand up to 64 cores. Thanks be NNUE! It is more important not to miss anything than to calculate too deeply.

In my EN test 2022, Charisma Saphir manages 115 solutions (Stockfish dev 110).
