sting-sf-3 release

[lech]

As earlier, Sting-sf-3 is based on Stockfish-211 and doesn't use any code of next versions.
Sting works as "One brain in one head" engine (play and analysis in the same way).
Sting is to prove that chess engines are able to solve many difficult positions (zugzwangs, long sacrifice, endgames, tactical) without tricks (!) and play on a very high level.
Sting-sf-3 contains many of changes in very important parts of the Stockfish's code.

In my tests new Sting seems to be stronger than the previuos version, but it is no main goal of my work.
I hope Sting can be a very good tool for chessplayers and study composers.

Many thanks for the Stockfish's team for open source code and Jim Ablett for nice logo.
Sorry, but Sting-sf-3 needs 64-bit-compilation-exe files, if I may ask, I need the help.
I prepared two 32-bits windows compilations only: http://www.mediafire.com/download.php?bnryd9jib3p0zye
If you run Sting-sf-3 bench, it should return 6450727 nodes.

New features let Sting to recognize zugzwangs delayed by pawn moves:
5K2/k7/5p1p/1p3p2/bP6/1p6/1P5p/7B w - - bm Ke7;
or solve quickly tough endgames like this:
1b6/3kB3/8/1KpPp2p/4Pp1P/5P2/8/8 w - - bm Bf8;
But many of such positions needs a very strong computer, though.

As earlier Sting is able to find such a sacrifice:
8/5pKN/5Pp1/5kP1/8/Bb6/8/7q b - - bm Qxh7;
Another feature can be very useful in some tactical positions too.

I prepared two 32-bits windows compilations only: http://www.mediafire.com/download.php?bnryd9jib3p0zye

Both the compilation was prepared under Windows-7 (i7). First (better) can return some problems under Windows-XP.
The compilation is ~ 15% slower than Jim Ablett's.

First mini test is not bad.
A compilation of "friend" without fanfare but hopefully work on all machines.
How touchstone not bad.

First (better) can return some problems under Windows-XP.

Indeed (Win XP 32-bit)
First:
I get "Entry point of ReleaseSRWLockExclusive procedure cannot be found in KERNEL32.dll library"
Maybe something has to be added in the same directory...

Second:
seems OK, but bench or Sting-sf-3 bench commands don't work (=> Unknown command)

But those glitches will soon be overcome, thanks Marek!

Another OLD_LOCKS 32-bit enabled, Sting SF 3 VE_x32 - it doesn't work under XP.
I recommend "my" two 32-bit compilations. One of them should work.
