Re: Mario Matouš study
Maybe nullmove- related. Sting and Huntsman get it at once, CorChess (less nullmove- pruning too) much sooner than SF dev., Dragon 3.3 also almost at once, regards

I only tried it on my weakest, working laptop with 4 cores. Stockfish nothing even after 3 minutes. I tried Seer at random, also nothing. Of course it has to do with nullmoves, without them today's computer would probably handle it almost immediately.
Yes, Dragon has it almost instantly.
Berserk, Ethereal within a minute nothing, but need Tal very quickly

Well, yes, but the original study by J. Mendheim (HHdb 0620.14g6b8) from 1832 starts 2 moves earlier with
[d]rkr5/p5p1/Pp4Kp/8/3B4/1B6/8/8 w - - 0 1 There SF 240101 still takes some time for correct output- line and DTM, Lc0 on the other hand indeed solves this one original starting position at once too:
