Fat Titz 1.1 released!

[AlexChess]

The previous thread has been closed for an unknown reason (perhaps for off-topic unrelated to the engine?). As far as I know this was the first engine to have its thread closed, and I feel discriminated.

Fat Titz 1.1

Changes:

• मुझे पढ़ें का हिंदी अनुवाद जोड़ें
• 添加中文自述文件
• Fix "Use NNUE" UCI option, now works correctly
• Fix not printing "holy hell" when ep is the bestmove in the Anarchy mode.
• Update to "do more LMR extensions for PV nodes"
• Update to "CMH Pruning Tweak"

Note: The new nodes speedup formula with 3 fundamental constants by Additional Pylon aka ChickenLogic was unfortunately lost due to a github force-push malpractice. Stockfish should be thankful for this loss as otherwise the engine would just be unbeatable.

New binaries available here: https://drive.google.com/drive/folders/ ... sp=sharing. The _bin zip doesn't contain the net, as it has not changed.

Fat Titz 1.0

This is a FREE UCI-compatibile chess engine. It is a fork of cfish.

Thanks to Norman Schidt and Albert Sliver for inspiration on creating my own fork of Stockfish. Also big thanks to Robert Houdart for great optimization ideas, overall making the engine almost 20% faster!

This engine uses a HalfKAv2-2048x2-64-64-1 evaluation network, which contains whopping 4 times the knowledge of Stockfish 14. It was trained partially on Lc0 data, which gives it a unique positional style, while still preserving the tactical sharpness of Stockfish. The network was trained using a modification of the state-of-the-art NNUE trainer, utilizing publicly available datasets 1, 2, 3

Due to the large size the release is available only on google drive here. It includes Windows and Linux binaries for all supported architectures, along with the network. This is the only place where the network can be found.

The people here that think Fat Titz is an appropriate name should consult with their wives or daughters.

But I guess they probably don’t have them.

You can not fix this Michel. Pubertal twenty-somes who suffer from Corona-Lockdown stress are taking over TC with their gamer-culture. Bullying, in-group-thinking, flame-wars, blabla...there is a reason people like Dann, Chris or Mar do not come in here anymore.

As someone who's been reading talkchess (but not participating) for a long time, I have to say I think you've hit the nail on the head.
It seems antagonism and hate have been ratchetted up significantly in the last year or two. This engine, it's name, way it was released, it's adolescent attempts at demeaning others, and the arrogance to bully CCRL is offensive. I sincerely hope that the new set of moderators will ban behavior like this.

Thank you for expressing your opinion. Regarding the engine, however, I hope that it won't stop you, or anyone else holding similar opinions, from taking a look at and playing with Fat Titz.

I might take a look when you call it Fat Frutz or something less offensive.

If you're thinking of testing it, I would save the time and electricity...

Test results are showing it equal to SF dev or significantly inferior
http://talkchess.com/forum3/viewtopic.p ... &start=240

Quadrupling the size of the net and adding some UCI options may be considered to be innovative by some, but it's pretty clear it's not an advancement.

It's appears to be a simple derogatory CFish clone/derivative meant to insult. AsmFish, Crystal, Sugar, BrainLearn, CorChess, RaubFisch, & Shash are more interesting.

That being said, if the author continues and does indeed come up with an improvement, let's see the test results...no one would be happier than me and I'd be the 1st to congratulate him.

What makes you think that any of those forks have more changes than Fat Titz does?
