My project is to prove that chess engines, without a.i., are able to solve all positions and save a high level of play.
Sting is based on the open source code of Stockfish 211 only and holds on the ELO level.
As earlier, it is "one brain in one head" engine. It means to play and analyze in the same way, without tricks and parameters.
It corrects the version 3 and ends the problem of zugzwangs.
Now Sting can solve such an very difficult for engines position, quickly (dualcore - less than half hour).
[d]5K2/k4p1p/5p1p/1p3p2/bP6/1p6/1P5p/7B w - - bm Ke8(e7);
   ::    ::    WK    ::
BK    ::    :: BP :: BP
   ::    ::    BP    BP
:: BP ::    :: BP ::    
BB WP    ::    ::    ::
:: BP ::    ::    ::    
   WP    ::    ::    BP
::    ::    ::    :: WB

The next step: how to evoluate the value draw (fortress).

I just tested with this position :
[d]8/8/4B3/6p1/7k/8/4pPKP/8 w - - 0 1
   ::    ::    ::    ::
::    ::    ::    ::    
   ::    :: WB ::    ::
::    ::    ::    BP    
   ::    ::    ::    BK
::    ::    ::    ::    
   ::    :: BP WP WK WP
::    ::    ::    ::    

But as other engines, it doesn't find that 1.Bg4! is clearly stronger than 1.h3?
1.Bg4 e1Q 2.h3 -> draw !
1.h3 g4! -> 0-1 !
Thanks to you if you are able to correctly evaluate fortress !

Thanks Marek.
Do you know if somebody is producing a 64-bit compile for you?

Regards,
Graham.

Hi Graham, sorry but I can't do 64-bit version. It would be some misuse to ask Velmarin. Embarassed

Hi Vincent, belive me the next version of Sting will find 1.Bg4!! and fortress in this position.

This must be some kind of a speedy compile world record or something, or some cosmic phenomenon. Thanks Marek and Marcel !

Oops, Marek and Marcel must have sounded too funny in my head.
I of course meant thanks to Marek and Julien !
Totally coincidental, but anyways...

Hi Marek,

The TDM-GCC compiler is a Windows 32-bit application that can produce 32 or 64-bit exe files. So there is no reason why you can't create a 64-bit version -- you just won't be able to run it.
