The 130-year-old Babson task was recently solved in a study by G. Costeff, although the position is not reachable. Might be a good test problem; also, it needs verification.
[d]4n3/pr1n1Ppp/p4krb/P2PN1p1/K2P2P1/PN6/1Bppp3/2R1N3 b - - 0 1
Black to move, white wins.
If 1...d1=Q then 2. fxe8=Q! only winning move.
If 1...d1=R then 2. fxe8=R! only winning move.
If 1...d1=B then 2. fxe8=B! only winning move.
If 1...d1=N then 2. fxe8=N! only winning move.

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: Babson task
latest stockfish is not the right engine to analyze it.
after 1...Ke7 it can see nothing even after more than 1B nodes.
