Hello. So here it is the version for the second stage of TCEC. Is really a minor version, with luck +5 elo.

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!

Thanks a lot, I am very curious.
Moreover I wish you good luck in TCEC. Andscacs still undefeated after 21 rounds!

I forgot to mention that next versions will probably be closed source again.

Thanks Daniel. It is amazing to see how strong Andscacs is in long games when playing in TCEC. You have done an amazing work so far.
Only 5 elo improvement ? I thought you and I had an agreement, that when you release new version, it is going to be 50 elo... Smile Smile Very Happy

I was wondering if you can add parameters to Andscacs like the one Texel has ? I very much like to tweak and tune the engines. The more parameters Andscacs has, the better Smile Smile

Hi Daniel,

I tried Andscacs 0.92.1 in Cutechess GUI under Linux and it doesn't start(segfault).
It does work starting from the command line in a terminal.
Version 0.92 worked in Cutechess GUI under Linux.
0.92.1 does work in Arena for Linux.

Kind regards,

Antonio

Thank you for this wonderful engine!

However, I can't build it on Linux (Fedora 26, g++ 7*). The source includes windows.h. After commenting that out I got more errors I couldn't solve yet.
