Stockfish Polyglot: Updated July, 14 2019 .

This distribution is the expansion of Stockfish beta having timestamp: 1562989754 - Simplify previous commit by using the full bonus for LMR-triggered stats update.

COMPILED WITH A DIFFERENT FORMULA. This executable is even faster than the original Stockfish beta binaries, althoug I'm not sure it works on other computers than mine. If you encounter problems please write me.


See the tests:

- Versus the corresponding Stockfish beta distribution

Stockfish Polyglot - Page 3 Speedtest


- Versus the last RomeoA28 CFish 64bit compilations

Is it useful for analysis, or just for matches between the engine?

At this point, given the Contempt disabled and the speed of this latest release, I guess you can use it for both. I don't know if it works on other computers though... I need a feedback.

CORRECTED ARCHIVE: DOWNLOAD AGAIN AND PLACE THE THREE DLLs IN THE SAME FOLDER IN WHICH YOU INSTALL THE PROGRAM.

Stockfish Polyglot: Updated July, 28 2019 .

This distribution is the expansion of Stockfish beta having timestamp: 1564104812 - Bug fix: always choose shortest mate in multithread mode.
In current master, with the voting scheme the best thread selection may pick a non mate or not the shortest mate thread. This patch fixes this bug. Formatting suggestion by Jörg Oster.

I've switched back to the old compilation method, as the gcc one gave some unexpected losses...

Stockfish Polyglot: Updated September, 30 2019.

Changelog: this distribution is the correction of Stockfish beta having timestamp: 1569581207 - Extend castling independently of singular extension.

Stockfish comes back to be in average speed, scoring 1800 milliseconds in the 64-bit benchmark. There was an unreleased version which I matched against BrainLearn, Stockfish Polyglot was winning. I wouldn't be surprised if this toy engine I've created just for fun is the strongest engine around. Someone testing it versus other engines is welcomed

FOR WINDOWS, LINUX AND ANDROID (but August 25 version). NO MACOS.

Stockfish Polyglot: Updated October, 9 2019.

Changelog: this distribution is the correction of Stockfish beta having timestamp: 1570265137 - Remove temporary shelter array.

I apologize for this late release, but these days I was busy with voyages and medical examinations, as I have written before. And please excuse me if I cannot make the usual benchmark but I only have my laptop here.

I was referred by Costantin P. that this is a particular strong release.

I don't own a Macintosh computer, I've tried to compile it through clang but it was unsuccessful. If someone shows me how to compile the source from Windows or Linux to macOS I'll be glad to do it by myself, but the method must be 100% working. Same thing for Android, I wasn't able to compile it under Android Studio nor NDK by myself.

Stockfish Polyglot: Updated November, 6 2019.

Changelog: this distribution is the correction of Stockfish beta having timestamp: 1572909323 - Rook PSQT Tuned.

For Windows, Linux, Android (August 25 version) and macOS (October 27 version).

This is a non-aligned update, as I'm not able to compile for Android and macOS, so I have to take what I can; the Android version is the same of August 25, for macOS I got this compile the last time but I had no time to update it. I take the opportunity to ecceptionally write on the same line to caution the morethanchessagame forum users to remove the free sharing of one of my previous books because they are private. I permit the reselling of previous books but not the free sharing. I would have directly written this message on that forum but my subscription request never received an approvation. My nickname on chess forum is kramnik. If I don't see the book thread removed from morethanchessagame I will be sadly forced to make a legal action.
