I had this position as an exercise many years ago.
It is also in one of my chess books now from a blitz game from 1966
Dvoretsky-Zilberstein and in the same page the book mention the words combinational vision as one of the titles in the page before giving the position.
I told the coach more than 20 years ago that the computer suggested Qf4 with a big advantage and the coach suggested to replace the computer.
Many years later
Stockfish cannot find Rxd7 Kxd7 Qa7 and also suggest Qf4 that suggest a very poor combinational vision by stockfish.
I believe that Rxd7 mates faster but I am not sure.

Hi Uri,
Curious that Stockfish sees something completely different from Kaissa here! Kaissa IV only considers Rxd7, but expects the reply to be 1... f5, 1... f6 or 1... Bc5.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

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.

Re: Test the combinational vision of your engine
Here is an informative snippet from a search by Stockfish-dev.
It seems what happens is that Qf4 is recognized quickly as being winning, while Rxd7 ends up near the end of the movelist. Then, because of late move reductions I assume, it takes a long time for Stockfish to ultimately see that Rxd7 leads to a shorter mate.
Should add that I don't see this as a significant problem with Stockfish.

Re: Test the combinational vision of your engine
I checked with many engines and it seems both moves are almost having equal eval due to
Qf4 move having the possibility to transpose with Rxd7! on its next move too.
The Qf4 PV actually shows Rxd7 on its next move.

Re: Test the combinational vision of your engine
extremely good combinational vision by stockfish lead it it other combinational winning lines with very fast evel raise.a very poor combinational vision by stockfish.
Stockfish is not DTM-solver, there is no elo-bonus in tournaments for shortest-DTM lines
To claim "poor vision" you have to provide position in which engine cannot win fast or win at all (or loose in drawing position)
Qf4 line lead to Queen material win in 5 moves

Re: Test the combinational vision of your engine
Ugh, I had not even noticed that Qf4 is the second move in the Mate in 13 PVs also in Dann's PV so the possibility for a transposition is very high. But maybe not a perfect transposition in that case it would just be a matter of move ordering which move gets searched first. According to Kaissa, 1. Qf4 is # in 16 moves maybe it missed something but it already knew the M13 here in the hash table. So after 1. Qf4:

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Re: Test the combinational vision of your engine
When I was checking the line after 1...Be7 2.Bxe7 Bc6 3.Bd6 Qxc7 4.Bxc7 O-O, I found a weakness in Stockfish, unable to find quickly the sacrifice to mate : Bxf7+!Eelco de Groot wrote: ↑Tue Oct 16, 2018 2:30 pmUgh, I had not even noticed that Qf4 is the second move in the Mate in 13 PVs also in Dann's PV so the possibility for a transposition is very high. But maybe not a perfect transposition in that case it would just be a matter of move ordering which move gets searched first. According to Kaissa, 1. Qf4 is # in 16 moves maybe it missed something but it already knew the M13 here in the hash table. So after 1. Qf4:
