Hi, I was watching one of the GingerGMs (Simon Williams) youtube videos and he put the below puzzle up for people to solve. Apologies if everyone has seen it before but none of my engines can solve it and simply think black is clearly winning although it is a drawn position based on the fortress setup.

7r/p3k3/2p5/1pPp4/3P4/PP4P1/3P1PB1/3K4 b - - 0 1


It is black to move and how can white defend against the obvious ... Rh2
8/p3k3/2p5/1pPp4/3P4/PP4P1/3P1PBr/3K4 w - - 0 2


Try not to look it up lol and test your engines

I know this position. No engine solved it in reasonable time.
After Rh2 white plays Ke1 or Ke2.

These positions are derived from ECE3.0981 with king moved one square. 
There is some discussion here:
http://forum.computerschach.de/cgi-bin/mwf/topic_show.pl?tid=706
Computers actually do find the right defense, but wood count keeps them from showing it as a draw.
For instance, it is solved here in 80 seconds by Sting 140 (the other is solved instantly, but of course, the prior analysis was in the hash table):

Hi, Wow I tried the version of Sting that I have and on my setup it basically found the idea after 2 seconds :eek: it wants to play Ke2 but it the same thing and was only running 8 cores although it may have been 4 and 8 with HT

I wonder if it has anything to do with the contempt or the pruning? I will have another look when I get time

I always use several engines on highly difficult positions.
Houdini 6 Tactical
Stockfish
Komodo and Komodo MCTs
Sting
Shredder
Is a good collection.
Most of the time I know the answer in advance because I got the positions from problem sites like yacpdb.
That collection has different analysis and covers a spectrum of problem and position categories.
I also have special programs for special positions (like nearly complete wall formations).
And I aso have some fairly strong hardware.
However, my powerful machines are usually scheduled, so it takes something important to interrupt them.
