So you didn't get the demanded winning eval for 2 (Mirror), 6 (Guard Change), 16 (Smothering 2), and 20 (Roundabout) , nor the demanded drawing eval for 5 (Stubbornness) and 9 (Shelter). And that just among those at which the first move was found at all.
In other words just 7 out of 20 positions were solved correctly by SF on your machine in 15 minutes.
Thanks for trying and reporting, Vincent!

Stockfish-dev solves this one, at about depth 60 on 20 cores. So I'd rate this one a 2; Stockfish seemed very confused for a long time.
Pretty study!
Houdini 6.03 on 14 cores gets this one in just over one minute and does see the draw. Seems it is able to zoom in on the solution quicker.

Sorry, Marek, not quite.
After 2.e8Q Rf7 3.Qd8(?) doesn't "shield" the King from Checks, which is the theme of the study.
3.Qe7 does.
Here's Sting's Output after some Backward of the solution line and 3.Qe7:
[d]8/4Qr2/8/6PN/8/3K1ppp/4prkb/4Bbnn b - - 0 1
Analysis by Sting 10.1 based on Stockfish 2.1.1 64bit:
3...Rf6 4.Qe6 Rf5 5.Qe5 Rf8 6.Qd4
+- (#22) Depth: 24 00:00:11 285MN
And here after 3.Qd8(?):
[d]3Q4/5r2/8/6PN/8/3K1ppp/4prkb/4Bbnn b - - 0 1
Analysis by Sting 10.1 based on Stockfish 2.1.1 64bit:
3...Rd7+ 4.Qxd7
= (0.00) Depth: 29 00:00:14 223MN
Black's gonna get stalemated.
Peter.

Thanks Peter!
It was my mistake. Of course, after 3... Rd7+ 4. Kc2 Black can play better 4...Rd2+ 5.Bxd2 e1N+.
It would be wonderful if the solution looks like this:

Maybe, I can't be friendly, but let me be useful.

Sorry, Marek, this time, there's a bug in your line at 6.Kc2?, allowing the Check with 6...Rc7+, and again White has the choice only between perpetual Check or Stalemate of Black, if taking the Rook.
Louis gave to you the link to Chichitza already, did you see?

So you didn't get the demanded winning eval for 2 (Mirror), 6 (Guard Change), 16 (Smothering 2), and 20 (Roundabout) , nor the demanded drawing eval for 5 (Stubbornness) and 9 (Shelter). And that just among those at which the first move was found at all.
...
I started some 1 hour search for this 6 positions, trying to reach the theorical eval (+- or =) :
2 (Mirror) +-
5 (Stubbornness) =
6 (Guard Change) +-
9 (Shelter) =
16 (Smothering 2) +-
20 (Roundabout) +-
Results this evening.

Of course, I like it much much better. Give me the last chance!
