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.

My favorite engine for this beautiful study from Peter Krug at the moment is SF Matefinder (yesterday's update) in Study Mode.

It has the solution with winning eval almost at once in output with 24 threads (CPU, not GPU :)).

Edit: CorChess 2.2 is default as well solving this under 2 minutes on same hardware at one single try, don't have the edit- time to repeat now anymore.

First try was 1 minute 50 seconds, second one only 8 seconds, third one 30".

I ran houdini 6 for over 4 hours, and it didn't find it. It showed a brief blip with a6 showing +1.5, but then switched back to Be7.
I had to walk the position through to:
1.a6 bxa6 2.Bc5+ Ke4 3.Bg6 Qa5 4.Kg8
and then it found it !
