Thanks Sergei. I hope SmarThink MP is on its way.

50 Elo gain sounds good.
Thanks Sergei.

One question: what is the difference between the 'standalone' binaries and non-standalone ones?

Seems to work for me. What happens when you run it?

This is what I see:

I'm just realised that values.txt is missing in smt195.zip
Please redownload it because w/o this file the engine will play much worse.

Standalone versions don't require Intel redistributable package to be installed.

Hi Sergei,

at first, thanks for SmarThink 1.95!

I try out the 1.95 AVX and 1.95 AVX standalone versions.
Windows 7 Pro with Shredder Classic GUI.

The following *.eng file (only the two exe files and values.txt ... you added today in SmarThink download directory on your site ... in SmarThink directory (without the older SmarThink.ini).

eng file:

Code: Select all

[ENGINE]
Name=SmarThink 1.95 AVX x64
Author=Sergei S. Markoff
Filename=C:\Chess\Shredder_12\Engines\SmarThink_195\SmarThink_195-AVX-x64.exe
[OPTIONS]
PawnHash=16
SyzygyPath=c:\Chess\_syzygybases

Now the following constellation:
I edit a position for checking syzygybases (works fine or not).

White King: h1
White Bishop: h3
White Knight: h2
Black King: h8

I can see ...

Found 0 tablebases.
Found 35 tablebases.

1. Why "Found 0 tablebaes" at first?

Now I start the analyzes ...

Found 0 tablebases.

2. Why SmarThink will give not a mate information?

OK ... I am looking again in UCI Parameter of SmarThink and see this one ...

3. Double entries ...

Have a look here:
www.amateurschach.de/common/smarthink_195-avx-x64.jpg

If I load again and again ...
More and more of the same entries in SmarThink UCI paramaters.

Same with the other AVX version, other versions not checked.

Best
Frank

Maybe mistakes by myself?
