Those are the only problems from the database that I have not been able to resolve to checkmate.
I just tried

It is an easy solve

is "Stockfish Exp 230420" just a development version of SF, or is it some modified, special build? (Exp sounds like 'experimental' to me)
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.

Not sure, I found a reference to it (not sure where) and used the link provided. It does behave differently than most SF derivatives and does find mates where others fail. I'll look for a reference and if I can find it, I'll pass it along

I only want it if it comes with source code.
I am very picky about GPL clones.

Contact MMarco, I think he was the first to reference the engine.

You're in luck! It does come with source code included.

You can download it from here:
