It does seem to need real matefinders. I wonder if a program like Chessmaster (The King) can find it? Or Houdini? Solution is not found by both Rebel and Swordfish:
The interesting thing about this mate in 19 by Gia Nadareischwili in 1949 is that it is actually and endgame study rather than a direct mate, it also was shown to have duals, but if you go by endgame study standards there are about 13-14 duals on move 2 (that are considered far worse than the dual pointed out at move 10 in the link because they are on move 2), because the King can move to any square and still win the game as well as the dark square Bishop of white can move almost anywhere on move 2 as long as it doesn't move to a square where it can be captured. The solution shows a mate in 21, but there are better moves at moves 10 and also possible at move 11 to make the mate in 19 moves.

Here is the link to the study:
https://www.yacpdb.org/#search/M0s0MXA1 ... LzEvMS8w/1
I searched the problem into the original source:

https://web.archive.org/web/20220523050 ... SSR''.html

The problem was published at Nº 2 issue of 1949, bottom of page 55, study Nº 17 (without diagramme, in the table with the title 'Studies with commendable reviews').

The solution was published much later than other studies of that issue —or at least I have not found it in earlier issues—, more precisely at Nº 11 issue of 1949, bottom half of the right column of page 337. The title is 2 moves faster. Then:
Study by G. Nadareishvili, who participated in the competition dedicated to the 16th championship of the USSR («Chess in the USSR» No. 2), after the first nine moves of the solution, comes to the following position:

Here the author, continuing 10. Ke2+, ends the solution with mate on the 21st move.

However, as I. Khvalchev (Uzhhorod) writes, after 10. Kd3+ checkmate is achieved 2 moves earlier —10... Kb1 11. Bd5 b3 12. Bxb3 b4 13. Bd5 b3 14. Kc3 Ka2 15. Bxb3+ Kb1 16. Bf4 h5 17. Bc4 h4 18. Kb3 h3 19.Bd3#.
So the checkmate in 19 moves was found on the same year, way before chess engines were available. Truly remarkable!

Hi Jesus,

Thank you for all of the excellent information and links, I truly appreciate it, so this was published as an endgame study and had several duals at move 2? I understand that it's easy for a clown like me with the benefit of computers to talk about duals in this study especially since he didn't have any engines back in 1949 :D I was just wondering if it truly was an endgame study or perhaps a direct mate problem.

As I understand it, this is a study, as the title of the table suggests. Other thing is that the author freely submitted a full line until checkmate and other composer was able to shorten it, but the important thing is the theme of 2.- Bh6 to enable the white king to cover the c1-h6 diagonal, avoiding the stalemate.

The bottom of the table says: 'In studies Nº 13 and Nº 15 — draw, Nº 14, Nº 16 and Nº 17 — win', so the stipulation of this problem is 'Win' and not 'Checkmate in X moves', as other problems in this issue. This study was Nº 16, so I take this opportunity to correct the typo of my previous post, where I wrongly wrote 'study Nº 17'.

Just to complete, the five studies of that table titled 'Studies with commendable reviews' were:

Nº 13: draw. (YACPDB 348521)
Nº 14: win. (FEN: 8/2p1p1Q1/2p5/2P5/2p1p3/2PpP3/pp1P4/rk1K4 w - - 0 1) → by Ф. Бондаренко (F. Bondarenko). It is an easy checkmate in 6 for engines, but remember that is stipulated as 'win'.
Nº 15: draw. (YACPDB 293310)
Nº 16: win. (YACPDB 275543)
Nº 17: win. (YACPDB 285468)

I hope no typos.

This problem by Lazard (YACPDB 281707) is another joy. SF 15.1 with NNUE disabled and single core, for being deterministic, quickly sees 1.- Ne4+, Kh4; 2.- Ng3, Qf8; 3.- Be1, fxg3; 4.- Bf2 from the start with slightly negative, near 0.00 evals.

Re: White to play and Win, very difficult for engines

This chess puzzle is NOT that easy for engines to solve, let see is Huntsman, Crystal or any other engine can solve it :roll:

Important to add the castling flag to the FEN. I learn that this is a rare type of problem that features a Valladao (or Valladeo) task or theme, that is, en-passant, underpromotion, and castling all occur in the main line:

There are longer checkmates in this problem, of course. Anyway, feauturing all these things in a problem must be very difficult.

Valladão seems the correct spelling according to both ChessBase and Chess Notes.

Important to add the castling flag to the FEN. I learn that this is a rare type of problem that features a Valladao (or Valladeo) task or theme, that is, en-passant, underpromotion, and castling all occur in the main line:

There are longer checkmates in this problem, of course. Anyway, feauturing all these things in a problem must be very difficult.

Valladão seems the correct spelling according to both ChessBase and Chess Notes.

I wonder why Dragon 3.2 and other top engines do NOT add the castling flag to the FEN automatically :roll:
NOTE: Also the best 3rd move is NOT 3...Kh5, but 3...Kh6 for Black
