And the transformation into a rook is necessary (2.b8R or 4.b8R)

All is ok. The move 1.Kc5 instead of 1.b7 makes the solution only a bit longer without any sense.

3k4/1p3b2/1Pp3p1/2Pp1p2/3P1P2/8/4K1N1/8 w - - 0 1 Win or draw I created this postion and Sting says Ok this is win but any other engine have 0 as eval even after 2 hours Is a Sting bug or there is really a way to win ? I really need to know the way to win, if this is true. thanks. Analysis by Sting...

Many of you can't understand that searching doesn't return the result (excluding mate score).
If you want to know the result try "auto-playing" or playing.

Position 35 is part of the study Detour (2010) , which has been discussed here in some topics over the years: White to move and win. 7q/b1p5/1p1Npkb1/pPP2ppP/P1P5/3B2P1/5P1R/K3R3 w - - 0 1 Have fun! Probably here ("IQ" test) are many positions based on studies. The position 35 rather doesn't happen...

Thanks, it is my mistake and I found 2 nexts. The corrected version is: The "IQ" test is a very important part of my project (Sting) and doesn't contain middle-game tactical positions and technical endgames. Here are positions dedicated to all engines to test so-called by me "quasi-intelligent" thei...

Another issue is the resource usage. I run it on my Windows Server 2008, 24 cores, 160G RAM. Even I set hash to 131072, the taskmgr said Sting only allocated 8G RAM, and CPU does not keep on 100%, unlike stockfish Sting is based on the old version (2.1.1) of Stockfish. Indeed, Sting can use "only" ...
