As earlier, the new Sting is "One brain in one head" engine, free of tricks and some versions, parameters and other tools.
I hope Sting can be a good toy for people and, as serious project, can break follower of an artifical inteligence.
Sting is based on Stockfish 2.1.1 with full respect to its authors and conditions.
The new idea help to solve positions with some sacrifices leading to fortress.
To close my project, Sting still needs some adding knowladge about simple draw positions and interpretation of draw positions.
The list of very tough positions, solwing by Sting, grows and it is very hard to find any new problem.

(only 32-bit windows version tested on intel procesors: Pentium IV, atom, i5, i7)

Some interesting and tough examples:

Thank you Marek. Much appreciated.

+1 !

Thanks Marek.
Hopefully Daniel might do a 64-bit compile as well.

Maybe it's me, but I cannot see the PV in either Chessbase 12 or Aquarium 2014 when starting an infinite analysis.

Sting is buggy. It displays the entire game as 0.01 even though it is losing the game. There is no change in evals.. It is stucked at 0.01 throughout the entire game

Sorry, it was my stupiid bug. I don;t use any GUI and I did not see it.

Version Sting 4.8.1 is here:
http://www.mediafire.com/download/9qaz6 ... sf-481.zip

Here is a 64 bit build that does not require DLL files.

Use :

instead.

That's the 32-bit version... Wake up, Dann !
