SmarThink v1.70 — July 2014 release of the engine. Major changes:
— output TT move before search in UCI mode (better output for analysis);
— code for pawn shelter/storm was completely rewritten;
— massive re-tuning of evaluation terms (material, passers/candidates, king attack etc.).

Thank you, Sergei. Not sure when I'll have time to test it. One of the reasons is that tests of 1.60 are still running...
Cheers,
Thank you for your testing!)
1.70 looks to be at least 60 ELO points stronger and may be even more)

Hi Sergei,
thanks!!
Is this new version compatible to AMD-processors now? Would be nice, but I still see "Intel" in the names of the .exe only...
Thanks and best wishes

CEGT-Team
PS: to be clear, I'm talking about x64-version. w32 is ok, but not of real interest (for me)

32-bit compile at the time only(
SmarThink\SmarThink_v170_x32.exe
64-bit AMD is planned for 1.80 (will be released after few weeks).

Hi Sergei,
I like your engine very much ... since many years.
Only king safty is a little problem for SmarThink versions. The attacking style in combination with good strategic moves after the openings are great. The style your engine is playing, no other engine have. Perhaps a bit to compare with Junior. Junior's style is also completly an other and very interesting.
It's clear that if you find interest again that your engine jumping to the best in a short time. Hope that you not lost your interest again.
Scala ... 1-6 (1 is the best) reagarding playing style ...
Your engine is one of my favorits and I think 1,5 you will get from myself.
Your new version is scheduled for FCT1 around August 20th, 2014. Perhaps Version 1.8 will be ready to this time? I am sure that the database with 45-minutes games on Haswel i7 4.3 GHz can help you to find mistakes. Can be download on my site.

Interesting that you posted this, since I noticed a significant drop in nps when probing Nalimov TBs. It only uses 10% of regular nps in an endgame with few pieces
. My recommendation is to ditch Nalimov use for now, and let the engine play on its own, until Sergei can fix the problems.
