Andscacs - New version 0.86

[cdani]

I published a new version, 0.86.

Changes:

* Solved little bugs.
* Improved various evaluation parameters.
* Improvements on king safety.
* Improved lmr.
* Improved some endgames.
* Added uci option "AlwaysFullPv" to show more complete principal variation.
* Some small speed improvements.

Should be clearly stronger, probably over 3100 CCRL with one core. But as always let's see if that is true

The biggest one-change improvement was with lmr, but the sum of changes in evaluation should be clearly more than that.

Sounds like another impressive effort. Thanks Daniel.

Thanks Daniel,
I have one wish: can you please include the uci command for setup?
I cannot setup a position and analyze with Andscacs (Shredder GUI)

best wishes

Hi. It has already the UCI command to setup a position:

position fen

And works well.
Is there any other command?

Hi Daniel,
when I setup a position inside Shredder Chess - e.g.

4k3/3pp3/8/8/3p4/8/4N3/4KB2 b - -

and I start calculation - I get following result (not more):
Engine: Andscacs 0.86 x64 1CPU (256 MB)

Bester Zug: O-O Zeit: 0:00.047 min

best wishes

edit: it works inside Arena ok - but not inside Shredder GUI - so I think, Shredder is missing a correct uci command somewhere. I will investigate more.

Here are the logs from the GUI

The FEN string is incorrect. The halfmove clock and the fullmove number are missing.
