Rebel 14

I think that you all overdo it with that attitude. What's the name got to do with anything? Is it written somewhere in the GPL that one has to give a certain kind of name to a project? The style of play of this engine is reminiscent of Benjamin and Rebel, and that's what matters most. Why should it be disingenuous? Open source code is open source to be reused, and Ed gave credits where due.

Ed has given us an interesting engine, with an interesting evaluation. I hope he will continue to develop it, and that he will continue with its experiments with NNs.

Hi Venon,

you wrote:
"4. NNUE code to excecute the Benjamin NN evaluation by Chris Whittington."

If I start to add all this information I can work months on the engine overview.
Example: I have to add all the names from Stockfish people for Stockfish, the entry to Stockfish will never ready.
This should be available on the web sites, github pages of the programmers / developers.

To much ...

Best
Frank

Rebel 14 - back to the roots of 19 years ago and 350 elo stronger than the latest ProDeo 3.1

Excellent new year gift!!! Thanks Ed for your generosity.

I agree...it's nice to see NNUE added to Fruit (and with an improved search!) .

Ed has been very vocal in the past concerning engines borrowing too much from open-source projects. Simex etc.
Apparently he's become more open-minded in this regard.

I do think that's a good thing, and I congratulate Chris W., Pawel K., and Ed (and Fabien L.) for this release.

(Rebel 14 though?, doesn't feel right...it kinda infers use of the traditional Rebel codebase...)

Norman, please...

I became much less active on this forum when all I seemed to see in every thread was some grumpy killjoy crying (and starting squabbles/ bringing toxic energy) about insignificant things instead of what *really* matters...chess.

In my view, having the work of people I consider computer chess legends (Pawel, Ed, Chris and Fabien) combined into something new is an amazing gift and I can't wait to see how this thing plays.

BTW...as far as I'm concerned EVAL is where the real chess is at, not search.

Put it this way...

With a human master, which part gives his "signature" which we call a playing style? His calculation depth (search), or his reasoning, biases and judgment when selecting moves (eval)?

Obviously, it's the latter, and since the NN (eval) was trained using Benjamin 1.1, this is indeed an Ed Shroder engine.

Okay, back to your bickering...

Well, perhaps you should have titled the latter "Fire" engines as "Stockfish dev" then?

Under Shredder GUI, it did not appear to be using book. Not sure if small_book.bin is internal or not. If it is not then the file was not with the download. Anyway what I did was use the book from Benjamin 1.1 and edited the .eng file.

Code: Select all

[ENGINE]
Name=Rebel 14 
Author=Fabien Letouzey, Pawel Koziol, Chris Wh
Filename=D:\ChessEngines\Rebel14\Rebel-14-avx2.exe

[OPTIONS]
OwnBook=True
BookFile=D:\ChessEngines\Rebel14\benjamin.bin

I think that benjamin.bin is a NN, not a PB opening book

I'm happy with this release but there are a few things I don't understand.

1. Was there ever a Rebel 13? If not, why was it skipped?

Yes and no see - http://rebel13.nl/rebel13/rebel%2013.html

2. Is what you have done the same what Albert Silver did with Fat Fritz 2, that is, take the search of an other engine and replace its evaluation with your own?

Brrrr.... what a comparison, which engine did Albert use, Fritz, Stockfish? I used my own and the discount is 500%.

I have tried to add to BSG

Code: Select all

{
			"default" : 1,
			"max" : 512,
			"min" : 1,
			"name" : "Threads",
			"type" : "spin",
			"value" : 4
}

...but still it uses only 1 CPU. When it will be MP it will be even stronger
