http://www.andscacs.com/andscacs087.zip

Changes:
* Improved various evaluation parameters.
* Improvements on king safety.
* Improved imbalances and space evaluation.
* Improved passed pawns.
* Improved some endgames.
* Improved lmr.
* Speed improvements.
* Solved little bugs.
* Tries to avoid to give draw too easily.
* Improved SMP scaling.
* Improved time management.
* Improved move sorting.

I will explain on detail the changes when Andscacs is out of TCEC.
Very nice - here are some games against my latest endeavor, Mikhail 1.10 (unreleased). Should call this version 0.10 really.

Again a lot of interesting changes.
Good luck with your new version.
I will test it a.s.a.p ... but I have a lot in my ToDo list so far.

You can count on it, do not know when, though.

Hi Daniel!

Thanks for the new version of Andscacs. I wonder if you have some
sort of estimation of the difference in elo between version 0.86 and 0.87?

Best wishes!

Finally nothing was wrong, other than the test that showed something wrong :-)
So you can use the downloaded 0.87 without problem.
Sorry for the inconveniences.

At last I found a bug!!!

Here it is the version with it solved:

http://www.andscacs.com/andscacs0871.zip

The previous version had an uninitialized variable that can evaluate randomly a parameter related to king safety. So sure was a few elo loss. Please, update your version!!

To be able to diferentiate between the versions, this one is named 0.871.
