Like to add a few of my collection.


[fen]r3rk2/ppq2pbQ/2p1b1p1/4p1B1/2P3P1/3P1B2/P3PPK1/1R5R w - -[/fen]

Mate in 7.

Solution requires the recognition of a couple of quiet moves.

Stockfish 12 - 17 seconds.
ProDeo - 7 seconds.

Is this position from a real game?
It is a composition, as Ed already answered. It was composed by Bwee and published in 1971 according to YACPDB (Yet Another Chess Problem Database):

https://yacpdb.org/#303652

The intended solution was checkmate in 32 according to YACPDB because the board position solved by Nawald starts after Nfg4+, Ke4; Nf6+, Ke5 is played. The next challenge would be try to find the checkmate in 32 from the original position:

[d]5n2/B3K3/2p3p1/4k3/7P/3bN1P1/2PrnNP1/1q6 w - - 0 1

I remember, that even 1990 programs solved 32 mover instantly. But SF14 not!
