To avoid in the future some offensive words that Sting is only some devilish trick, I will try to explain my work much deeper.
Both the positions (represent some wide groups) are very easy to solve for chessplayers.
[d]8/5pKN/5Pp1/5kP1/8/Bb6/8/7q b - - bm Qxh7;
   ::    ::    ::    ::
::    ::    :: BP WK WN
   ::    ::    WP BP ::
::    ::    :: BK WP    
   ::    ::    ::    ::
WB BB ::    ::    ::    
   ::    ::    ::    ::
::    ::    ::    :: BQ

[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

Also both are extremaly tough for engines. The problem is in so-called "null move search".
By my long and hard work I found a shape for the "null move search" which let us look forward to the solid chess engine.
There was needed to solve the problem of the "value draw" too, which can work like the black hole. I found the solution and still the value draw is ZERO.
Why it is important? At first it is normal or natural one. Moreover I will try to use the huge power (black hole) to evaluate zero (fortress).
I hope it will be in the next version (Sting SF 5) soon.
One condition is important for me too to maintain a similar ELO level of the parent egine (Stockfish 211).
