Easy for a computer, but I had to think for a while.

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.

Hello Dann:

Good position! Could you provide the source, please? Thank you in advance.

I thought some ideas without an engine, as suggested. Given my poor level, I am proud that one of these ideas was the correct (at least the first and the second moves was among my ideas) after checking with SF. I see this position as a combination of Greek gift sacrifice and Damiano-like checkmate (because of the pawn on f3) if defended incorrectly by white. It is needless to say that I will not win with black against a strong opponent even if I am right with the first two moves.

Regards from Spain.

Ajedrecista.

The source came from a forward position in my database which happens frequently yet is totally lopsided.

Amazingly, there are several white wins.
I wondered about how such a lopsided position {even after the key move it was not easy to see the win} could be achieved and decided one likely board will be the position given.
I analyzed the three following positions :
