I guess that for the positions where blue has problems it is depth, since it takes a long time to go deep.
For these last 11 only 3 were solved (c9 shows outcome of 2 hour search with 63 threads):

To see if the issue is depth, I am running the problems at one hour using bleeding edge SF to see if depth solves the trouble makers.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Only Sting-SF finds this 2 fortresses and trapped piece :
2b1r3/r2ppN2/8/1p1p1k2/pP1P4/2P3R1/PP3PP1/2K5 w - - bm Nd6+; id "Hard-Talkchess-2020.033"; c9 Nh6+;

Queen trapped :

Only CorChessV6 finds it in a reasonable time :
Nq3n1k/8/P1p2Npp/2Kp3R/pp6/n3p3/8/4Q3 w - - bm Nc7; id "Hard-Talkchess-2020.131"; c9 Rxh6+;
A lot of engines find this one (maybe a null move problem ?) :

Very tactical CorChessV6 like it fast. May be Bluefish-FD-XI is right and this move is over evaluated ? May be not ?

I guess that d6 is best, but the other moves would get some points on a varadic scale.

Don't forget to enable tablebase files. I would have tens of billions of tablebase hits by ply 55 here

1 new result -> Eman 5.40 with option "Full Analysis Depth=12" (same as default in Eman 4.30) takes the 2nd place.
It finds 4 positions more than V4.30 : 167 pos (929 sec)
