Stockfish 8 SSE (Special Edition)

[MikeB]

Stockfish 8 SE is the Special Edition of Stockfish as described here:
http://talkchess.com/forum/viewtopic.php?t=61952

So one might be wondering what is the SSE version? Back in the 80's, Pontiac came out with a Bonneville SE Edition model , but then when they came with a newer "top of the line" model Bonneville , it was the "SSE".

SSE incorporates Brainfish - more information here: http://www.zipproth.de ) , essentially, a deeply searched database of chess positions at its disposal. I created an opening based book on WCC games (available here http://talkchess.com/forum/viewtopic.php?t=61999), knowing this would give Stockfish a huge advantage against an opponent that did not have access to the same database - and we can see the results here:

Not fair to Komodo, and that should be recognized, but it does illustrate what Stockfish what can do when it has has access to a positional database and every line it plays is in the database.

Source and Mac exe can be for here: https://github.com/MichaelB7/Stockfish

You will need to download Cerebellum_light.bin from here: http://www.zipproth.de and please be sure to enter the path AND the file name in the UCI option BookPath.

Hi!
Don't understand fully: SF8SSE is the Brainfish- engine with SF8se-modifications and uses Cerebellum- library as well as your database?
And how to make it use your database?
The .epds only, you gave in the other posting, can't be enough I guess

The epds referenced in the posting is an opening set of epd positions , no different than what TCEC or a CCRL tester might use in testing engines .

[peter]

I see, Michael.
What I didn't understand, was how to make a book out of those positions only, but of course you had the moves leading to them stored too.

My main mistake will have been, that you meant public reproduce of the usage of this book you made together with Cerebellum and your engine.
For that we'd need the book too, not the .epds only. And of course some of us would need Windows .exes.

Michael B, thank you very much for your contribution, if not too much to ask could produce a compilation for Windows ?. From already thank you very much.

[fantasmadel50]

Michael B, that database of almost 62,000 positions, the anger you update and expand with future versions of the engine?

[fern]

wait, wait...do you have a simple exe I can download for windows 10, 32 bits?

You got THAT right.
Even my Grandma uses 64-Bit Windows

The epd file represents an opening book based on GM WCC games. It is a relatively neutral book and is suitable for use in a GUI that enables epd files to be used as opening books. Xboard is one such GUI. I am not familiar with other GUIs so I do not know if they can handle an epd book.
