I decided to replace position no. 73 (leads to too complex endgames) by an old good fortress example.

Thought game having already come to an end here anyhow
:)
Think it a good position too for engines to test their output- eval, even if the moves to solution are found rather quickly and easily by all of them I tried.
It's one of these 50 moves to be checked things, so you have to have much Forward to keep 0.00 in hash in Backward.
Here is arbitrarily chosen Fire after about 50 moves forward and going backward quickly:

q7/8/2p5/B2p2pp/5pp1/2N3k1/6P1/7K w - - 0 1

Analysis by Fire 6 x64 popcnt:

1.Ne4+ Kh4 2.Ng3 Qf8 3.Be1 fxg3 4.Bf2 c5 5.Bxc5 Qg7 6.Bd4 Qg6 7.Bc5 Qg7

The old no. 73 position was:
[pgn][FEN "7k/pp2Np1p/2p2P1N/5pP1/7K/P4n2/1q3Q2/5n2 w - - "]
1. Kh5 {win}[/pgn]
and its solution leads to many difficult time consuming positions.

I still don't understand the comments from Marek : "I decided to replace this position (leads to too complex endgames)"
It's again taken from another study made by Mihai Neghina, starting 2 moves earlier with this position:

[d]6Nk/pp2Np1p/2p2Pp1/2R2bP1/7K/P7/1q1n1Q2/5n2 w - - 0 1

1. Rxf5 gxf5 2. Nh6 Nf3+

leads to the position given

[d]7k/pp2Np1p/2p2P1N/5pP1/7K/P4n2/1q3Q2/5n2 w - - 0 3

with 3.Kh5! as continuation.

From the starting position it's about 50 moves to mate

One more change!
I add a very interesting example:
[d]1B1k4/3p4/1Kp5/PpP2p2/1PqP1P2/8/1P6/8 w - - ; best move a6 (win);
instead of (2):
[d]8/5pKN/5Pp1/5kP1/8/Bb6/8/7q b - -; best move Qxh7+ (win);
that appears again (71) in other better version
[d]8/5pKN/5Pp1/5kP1/8/Bb6/8/7q w - -; any move and next Qxh7+ (win);
All collection now is:

BTW. Next I will try add my commentary to each position to explain why it can be difficult for engines,
Maybe, I can't be friendly, but let me be useful.
