In my intention, Sting should "immediately" find some very difficult for engines and
obvious (often, but not always) for a human sacrifices, thus should return much more reliable analysis.
It works exactly like Stockfish, but with an added sensitive (option) detection of good sacrifices (in midle-game and endgame).
All changes in code don't clash with the Stockfish's source code,
and because it is advisable to use my idea on high depths (or "disabled" in option), a possible drop of strength (good compilation), even if it is impossible to get a profit from this in play, can be a few points only.
My compilation of the beta version is very unprofessional, thus the beta is slower than Stockfish 1.8.
But, of course, the main goal of this (I HOPE I AM WRONG) is other than ELO points.

Sting works with an option: "Sacrifice detection" 0 - 8 (0 = disabled, default = 8).
Have a good time with Sting!
