Re: Sting SF 20

The "IQ" test is a very important part of my project (Sting) and doesn't contain middle-game tactical positions and technical endgames.

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

Re: Position : Win or Draw ?

Many of you can't understand that searching doesn't return the result (excluding mate score).

Re: Sting SF 19

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" ...
