I'm not a GPL expert, so I really don't know all the implication of licenses of pieces of code that we can find in internet.
Sorry yes, I mean you suggested it :-)

The source has no license so I guess it's under public domain?
About the license, Elcabesa just told me that the WinGroupAffinity part of the code taken from Stockfish is incompatible with public domain license. Maybe the best is to remove it from Andscacs. In fact nobody is using it that I know. What do you think about? Thanks.
Since is a strong program I think you should choose a license: https://choosealicense.com/

Anyway a code without license has copyright https://blog.codinghorror.com/pick-a-li ... y-license/

I tried to make it compile under clang under Linux and ran into a couple of these errors:

The version compiled with gcc works without flaws.
I used gcc also to compile it for linux.
I will clean those warnings, thanks.
About the error at finals.cpp, at first sight I don't see what can cause the error, specially taking into account that works well with other compiles. I will think about it. Thanks.

Changes:
* Improved various pawn structure evaluation parameters.
* Move search improvements.
* Improvement of various imbalances.
* Improvements in some endgames.

http://www.andscacs.com/downloads/andscacs0921.zip

As promised the source code:
www.andscacs.com/downloads/andscacs921src.zip

Is a Visual Studio 2013 solution. Also it contains a makefile for Linux.
Michael will try to make a Mac version, thanks to him!
Daniel ,

What a great treat you gave to the CC community today. I love your engine a very unique style and very strong.

This run was just for fun and it was very quick tc (24 sec base)
K11.2.2 has really picked up its game with these micro time controls but I believe this may be a slightly lucky run. I checked the pgn and there was no losses on time by engine. Almost 500s point higher than Fruit 2.2.1 in this run.

In the es.cpp file.
The problem is that if I add a few parameters it will not make much sense. And adding a lot of them is just a lot of work :-) I'm sorry.
Ouch looks like I will have to go into Andscacs source and make these changes. The es.cpp file you just mentioned is there. :? :?
Too bad I am complete patzer regarding this. :(

Hi Daniel,

Version 0.921 doesn't work with Cutechess GUI in Windows and Linux.
Doesn't start(segfault).
Even when I start it from a teminal it crashes with the UCI command that sends Cutechess GUI ; go wtime 300000 btime 300000 movestogo 40
0.92 did work in Cutechess GUI in Windows and Linux.

Kind regards,

Antonio

I can confirm that. However, version 0.921 does work in xboard.

Solved! There was a bug with the movestogo keyword. Thanks for reporting!
If anyone will play a tournament with moves per time, should update the version.

I also updated the source file.
