SmarThink, an UCI/WB compatible chess engine by Sergei S. Markoff written in plain C. The engine contains a lot of knowledge to guide the search, and has an aggressive attacking style. SmarThink uses original techniques in search and evaluation based on complex analysis including the use of ideas of Mikhail Botvinnik. SmarThink played various tournaments in Russia, and became Russian computer chess champion in 2004, CIS computer chess champion at the CCCCISC 2005, and third at the CCCCISC 2008 behind WildCat and Strelka. New version, 1.40 (r2040) is free. Sorry, at the moment, only single-processor Intel x64/AVX version is available.

Engine will not work unless you insert Authors name. I'd love to test it but it will NOT run in Fritz GUI without the authors name so if that is what your running it in don't bother to download because it will not work without Authors name. I'll wait on the update.

Does not work under Fritz GUI, what i do?

the 32 bit is working!

I haven't tested it under any GUIs
but the exe executable alone works well

the last smarthink version was released like 10 years ago

and it is a huge comeback!

Because I know very little from the computer my system is:


Hardware: AMD Athlon (tm) 64 X2 Dual Core Processor 3800+ with 5,0 GB Memory
Operating system: Microsoft Windows Vista Home Edition Service Pack 2 (Build 6002) 64 bit

It suits some version with my computer?

But you have AMD, not Intel.

Pity…  
Because I read that she is aggressive engine, I have finished tournament measurement of aggressiveness of chess engines.
I want to try also certain other engines and afterwards I will publish.
I wanted to try him.

Works very well here on both console mode / Arena GUI. Thanks!

Still the same on both computers doesn't work at all. Bad sign when you see nothing in the authors display in this GUI when you see that good luck on the engine loading mine never has. If I can take some consolation it isn't just mine so many have not and can not test it. I wish the problems with Fritz 12 GUI could be resolved. I have downloaded many engines and outside of Java files I've never had a problem, this is very puzzling to me, if any Fritz users get it in after having problems let me know but I've spent too much time on this one issue and I give up.  

Hello !

SmartTink 1.50 works very well in Fritz 11-12-13 & 14 GUIs.
Maybe you have a system problem ? Double-click on exe (enter in console-mode), type uci and press enter. If you receive the message "uciok" your engine must work in Fritz 12. Otherwise is a problem with the Fritz 12 installation !

Best to you !

The latest exe gives SmarThink 1.50 as its name.

Where can I find a compile for Mac OS X ?

Have you placed values.txt in engine folder?
This version played over 3000 games w/o any problems, so, probably, it looks that something wrong at your PC.
