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.

Charisma SmallNet is the little sister of Charisma Diamond. A 12 MB small network is used. In the starting position, the engine as AVX2 version on 20 threads, calculates that much faster:

Charisma SmallNet: 26000 kns after 15s
Stockfish dev: 18000 kns after 15s

In my EN-Test 2022, the engine managed at 60s, great 110 solutions. In the ranking it looks like this:

1) Charisma, Result: 116 out of 120 = 96.6%. Charisma 64-Bit.txt (ZIP)
2) Crystal 5 KWK, Result: 113 out of 120 = 94.1%. Crystal 5 KWK.txt (ZIP)

I would like to point out, that the pure engine of Charisma SmallNet is not identical to Charisma Diamond. It's not just the network that's different.

I optimized the engine for practical play on servers. So far I haven't lost a single game on PlayChess.com with the small net! The strength of the small network is the middlegame with tactics. Here the small net is stronger than Stockfish dev. and is faster! Benefits for Stockfish dev. there are special complex positions in the endgame. Possibly also when playing with small books, and complex positions have to be solved at the beginning of the game. In practice, I play with normal theory and with books that already contain the known theory. The actual game usually begins in the middlegame. And here the small fast net cannot be defeated!

The engine contains all Brainlearn features. Thank you Andrea Manzo!

The network is EMBEDDED and the engine does not need a special folder with the network. I wish everyone a lot of fun testing the engine.

Thank you very much Eduard !
I see you're very prolific with parsing engines. Keep it up.

All the best.

Hello Eduard Nemeth!
If I use Charisma Smallnet, should I add Solista Attack V3 Bin?

[superbatil]

Sir Eduard Nemeth,
how do I find experience. bin file stored on android storage?

Have fun testing.

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).
