seems that "... no pretentions ... to originate anything" brought us the quote. By being the Analitical Engine it is so, but by being an Analitical Engine it probably originated at least this possibility of googling it up and commenting

i would start with the inclusion of castling :-)

By way of exception :-), castling is not used here, the rooks do not move. As a hint the last move is 5.. Ng3xRh1#.

before my seeing others’ comments: My solution [arrived to through the 32-pixel, B&W, restartable-moving-pieces setting and “(?)”]: in view of the following possibility\s::::::
pinned black knight invites rook mate\ \ ,,,,,,,,,,,,,,,,,,,,, it seems [ re-verification is intended later on and before seeing others’ comments] that white's nbtwo starts

"Most Difficult Problem? A game begins 1 e4, and ends on move 5, with the move, knight takes rook. What was the game?" For the solution and an amusing story on Kasparov's and Botwinnik's failure to solve it, consult The problem and text come from "The Joys of Chess: Heroes, Battles & Brilliancies" by Christian Hesse (2011).

A random move of wNc4 threatens 2. Rc4# and Black defends by unpinning bNe5. The tries 1. Nb6?, Nd6?, Ncxe3? fail to 1.. Ng7!, Rg7!, Bg7! as the mates 2. Bxc5#, Rd6#, fxe3# are blocked. Only on 1. Ncb2 all of these mates work out. Theme: White combinations.

Александр Николаевич Панкратьев (* 28.5.1954) Russian composer and FIDE Master. "Aleksandr Pankratiev is a well-known helpmate composer who also composed direct mates. He is very prolific and was documented on Jan Golha's website as a possible plagiarist due to the fact that a considerable proportion of his problems was anticipated."
