BTW BlueMarlin just has a few very very tiny changes in some material values inspired by Eelco years ago (scaling down by around 0.7).
The main difference in playing style is just that it uses a different NN from the Stockfish test.

Code: Select all

#define EvalFileDefaultName   "nn-a68688dd90ce.nnue"

Nope ! Blue Marlin 14.4a uses the latest default SF net ! Swordfish 14.4 uses nn-a68688dd90ce.nnue ! :wink:

I see, I compared accidentally to 'Swordfish', because the so called 'author' had both SF master sources in the same folder.
This makes the remaining changes for BlueMarlin even more pathetic though ;-)

Scaling down material by around 50%, adapting kingdanger to it and add a 'magic' optimism constant ...

This are all differences to SF for the used master (ouch) for BlueMarlin 14.4a

Re: Stockfish 14.1 regression

Post by Eelco de Groot »

The original Bluefish was only half an hour work, mostly of changing some values and compiling on my then still working TDM compiler. It was meant for Uly but he only saw that there was a post waiting for him on the sadly defunct Rybka forum, years later :( What has become of Uly, I hope he is safe.

Blue Marlin and Swordfish are fine IMO. That still is what the GPL project is supposed to do, in a way: inspiring people to contribute to a common project, without monetary gain although that is not forbidden as far as I know, understanding the software you are using by having the sources available fully, and documented. And sharing what you find yourself by making the changed sources public I'm assuming that the version from dorsz is the same 14.4a on the Immortal forum that Sylwy referenced.

Joost van de Vondele meanwhile has repaired the bug that Carl is talking about, the new version should now be downloadable on Abrok.eu although that is not an official version of Stockfish, it is developmental code still. The bug is probably not to blame for recent regressions, if any, because the code responsible, Lazy Eval, has been in Stockfish for a while, years.

But, reacting to Jouni's post, 14.2 will follow I'm sure, in due course and not too far in the future, if there is enough Elo gain for instance, that new release schedule was discussed already by Joost and others at the official Stockfish site; that there would be nade more frequent updates of the official Stockfish:https://github.com/official-stockfish/S ... sions/3368
Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Of course they are 'fine', but this thread is about those people, who praise every new and whatever miniscule changed derivate as the new grail
of computerchess and trying to prove OTH how different it must be, while having no clue what they are testing at all.
Then they post a randomly win of the 'new' derivate against current SF and believe they have found the new super duper engine.
The winners are the electricity companies here.

I never saw the same people speaking with such a positive verve about the original program(s).
It seems they are almost attracted by a new blinking name for a chess program alone.
Maybe I should 'release' some dozen coloured watermelon flavours of those forks under another anonymous fish pseudonym like 'john hering'.
That is the problem and I am fed of this behaviour.

My versions of Blue Marlin 14.4a & Swordfish 14.4 are from :

https://open-chess.org/viewtopic.php?f=7&t=3322

Published also in :

https://www.chess2u.com/t17647-blue-mar ... dfish-14-4

IMMORTAL is the game of Blue Marlin 14.4a versus Stockfish 14.1 I posted above. The true Immortal forum is dead. Years ago ! :lol:

14.1 is certainly not a regression at FRC.

Victory dedicated to Mr. John Hering (colored watermelon flavors & co. personality). Of course a random victory, absolutely accidental ....... although there are quite a few of these in my Stars Tournament ...... :wink:

I never saw the same people speaking with such a positive verve about the original program(s).
It seems they are almost attracted by a new blinking name for a chess program alone.
Maybe I should 'release' some dozen coloured watermelon flavours of those forks under another anonymous fish pseudonym like 'john hering'.
That is the problem and I am fed of this behaviour.
Victory dedicated to Mr. John Hering (colored watermelon flavors & co. personality). Of course a random victory, absolutely accidental ....... although there are quite a few of these in my Stars Tournament ...... :wink:

It's a trash black defense...any engine should be able to 'win' with White.

Oh, and the proper way to for a human to try to play this is:
1.d4 e5, 2.de5 Bc5 with 3...f6 to follow.
Still 'crap'...but I've won far more games than I should with it as black in blitz/bullet.
