And here you can see Sting SF 7.3 and Yuri Gusev defeat the formidable AsmFish 160830 in 'Gusev's immortal'. AsmFish senses trouble only on its Move 30. Until then, it thinks it can draw!

Hi Marek, thanks for this new version.
In this position :
[D]2k5/2p5/1q1p4/pPpPp1pp/N1P1Pp2/P4PbP/KQ4P1/8 w - -
Now Sting SF 7.3 plays very quickly always h4 ? instead of NxQb6 ??
But if White plays h4, Black draws after gxh4 followed by h3 and h4, maintaining the fortress.
If after 1 h4 gxh4 2 Qc1 h3
3 gxh3 h4
or
3 Qh1 h2!
Only move as Qd2! and then, somethink like, Kb3, Nb2,
Ka4, Nd3-c1-b3, White will win a5 pawn, and game.

But, for me very important is that Sting can reject the move 1.Nxb6 ??.
Note that after 1.h4! Sting as the best move suggests gxh4 !!! and if you starts to analyze after the two moves Sting again will reject the weak move Nxb6??.
Another question.
Sting (version 7.3) is not a closed project yet.
Still remains question of "the lazy King" too.
I think now the version 7.3 is the best version of my project and I see a great succes of my long-term idea.
A question of ELO racing is not that important now. People want a real chess engine and authors begin to understand it.
Sting is open source and I believe many can study and improve my ideas and I hope not only steal.
But h4?? is not good move.
Because fortress is created again.
For sure :
Only move as Qd2! and then, somethink like, Kb3, Nb2,
Ka4, Nd3-c1-b3, White will win a5 pawn, and game.
I repeat I am very happy that Sting can reject the move 1.Nxb6?? now.
It is a fresh and interesting but difficult idea and I expect understanding.
Again let you know that Sting is not closed project yet, and I am very happy that you support me.
