Sting-sf-45 release

I try to change it by this version (correction).
mediafire.com download/ezuwkwjpkb4h8sb/sting-sf-45.7z
As earlier, Sting is based on Stockfish 211 only (many thanks for authors!), is "one brain in one head engine" (to play and analyse in the same way, without tricks and parameters), and I can't do 64-bit version (sorry!).

The main goal of my work is to prove that an artifical inteligence (anything it means) is not nedded for chess and people.
I promised that the next version (> 4) will solve the big problem - draw eval (fortress). It means: how to get the zero value in draw positions in less than 100 moves (the rule 50).
But the version (45) doesn't do it!

Of course, I am working at this.
I have some idea, but it is not easy to do, maybe only to tune it.
I need a help, examples where the idea doesn't work well. I set the idea to work only if eval of any position in search is >= or <= the pawn value. I think, it should help (so long).
If you want to help me, please try this unofficial (32-bit) version with draw (fortress) detection:
mediafire.com download/em61vswatq9886b/sting-sf-X.exe
(let me know if you want the source code, but it is not ended!)

Posted by the author in Talkchess:

I closed the link to sting-sf-x.exe. It was rather a wrong idea. I apologyze for my passion, maybe a curse.

Sting Sf 4.6
mediafire.com download/yau5e4vbtlye8ao/sting-sf-46.zip

From the author:

I corrected my bugs in the last version (4.5) and added new functions (stalemate and trapped pieces detections).
It is very important in solving the main future problem the draw detection.

You can watch how works the trapped pieces detection in the following winning positions:
q1b4n/1p1pKp2/1p1p1Pp1/1P1P2Pp/2P4P/8/7R/1N1k4 w - - bm Ra2;
3k4/2pq3p/pp5R/4P3/P6P/2PN4/1PN3K1/8 w - - bm Nd4;
1k1n4/1p1b1p2/1Bp1pPp1/1PP1P3/8/6P1/8/1K6 w - - bm Bc7+;
BTW. You can use an old dual core too.

In Sicilian Najdorf, Sting SF 5 pushes f5 preparing for f4 and chains g5 creating a diagonal block against Texel 1.05's queen. With black rooks on open f-file and g-file, Sting SF5 has pawn pressure and better queen mobility.
