Must be a study. I hate not to know the authors of good studies. Not in YACPDB and not in Arves to be found.
Google always finds links to collections of such positions, but that doesn't help usually, because you don't even find the single position in the collection, and even if, there are no sources given neither most of the times

"Nine studies of varying difficulty were provided and the solvers were given three hours to find all the solutions."
But no more board there.

I added a few new good items proposed by Vincent (one a bit simplified).
Thanks Vincent, but one of main ideas of this test is: "to encourage, and not to discourage".
Now this valuable collection counts 77 items.
The test doesn't contain middle-game tactical positions and technical endgames.
Here are only positions dedicated to test so-called by me quasi-intelligent abilities of engines.
Don't use such a tricks like: multiPV, rule 50, null-move disabling, special parameters and others.
The time to solve each item should be 30 minutes for 1 000 000 nodes/second speed. It means 3 minutes for 10 000 000 nodes/second only. Of course, the going on depth should not be broken.
The draw result means ZERO score or a missing gain.
Here are rather easy, sometimes simplified be me specially, examples of possible problems for a clessic model of engines.
The spectrum of examples (xx items) and estimated time of solving are not accidental.

Hi Marek,

your added 8/5pKN/5Pp1/5kP1/8/Bb6/8/7q w - - (any move and next Qxh7+ Black wins);
is not clear:
what if white moves 1.Nf8 - no Qxh7+ is possible :)
what if white moves 1.Bc1 - now Qxh7+ is draw

Best is immediately black to move.
and this is already in the suite - 2nd row:

8/5pKN/5Pp1/5kP1/8/Bb6/8/7q b - - bm Qxh7+ (win);

and therefore twice in your suite.

Best is delete the added 8/5pKN/5Pp1/5kP1/8/Bb6/8/7q w - - (any move and next Qxh7+ Black wins);

Google always finds links to collections of such positions, but that doesn't help usually, because you don't even find the single position in the collection, and even if, there are no sources given neither most of the times

Thanks Vincent, but one of main ideas of this test is: "to encourage, and not to discourage".
Now this valuable collection counts 77 items

Yes, I simply propose some positions.
Though, this thread is a good space to put a lot of positions who required some understanding of chess.

About the suite :

To avoid EGTB, replace this position : 8/8/8/5Bp1/7k/7P/4pPK1/8 b - - am e1Q;
by this one : [d]8/8/8/1pB5/k7/P7/PKPp4/8 b - - bm b4;

And some more. Last add by me, I think we have enough about all patterns :

Opposite bishop, draw endgame :
8/p1K5/6Bk/PP5P/8/8/5b2/8 w - - 0 1; -> draw-no gain
--------------------------------------------------------------------------------------

Odd pawn endgame, d5!! :
5k2/8/pppppppp/8/PPPPPPPP/8/8/5K2 w - - bm d5;
36/37+ 00:38 704 608k 18 247k +7,41 1. ... cxd5 2.a5
--------------------------------------------------------------------------------------

Q vs R+N draw position (fortress) :
6k1/8/8/8/q5p1/3p2P1/3N1R2/6K1 b - - 1 45 ; -> draw-no gain
--------------------------------------------------------------------------------------

In my opinion that position is correct. Engines must identify that the black
Q must be sac'd with QxN to avoid fortress.

1.Nf8 is answered by Kxg5 with easy win for black (g6 becomes a deadly passer)
1.Bc1? is also Mate in 14 after Qxc1

I guess, the point of that position is to check whether engines will give up
a Q against a minor piece just to avoid a fortress.

Humans would identify the fortress and play QxN easily, but I am still checking other engines if
some of them can detect the sacrifice (assuming no 6-men-EGTB is used).
Maybe Sting and HIARCS can play the simplification technique QxN.
