who is it to move?
The most beautiful puzzle that my engine can never solve

White, of course. If it was Black, then he would have enough time to pick the e6 pawn, and then white should have to deliver a perpetual (or donate his Queen because of the stalemate) to avoid loss.

Then isn't it just a draw?

No. White can only move the queen, and Black the king. The king will be cornered, and Black will be forced to play ..Qb8-b7.
Yes the solution was find but what says the engine?

Ah yes I see now, I forgot black wasn't in stalemate!
Or try this puzzle with your engine white to move:
the engine says it is much better for black or?
it is actually a draw

Ba4+ and then you move all the pawns, I did a tactic like this!
At first pawn c4+
After Kc6 Ba4+ only option Rb5 and white is winning!!

It is actually a quick win for white, and you should stop posting nonsense.
Do you promote, trap the king and force him to sac the queen

I think there are multiple solutions to this puzzle. Personally, I prefer 1. d4, though, I know that there are several players who would go 1. e4 or 1. Nf3.
#29 is simply the wrong diagram. Stop posting wrong diagrams!

Yup. White would actually be simply winning after 1. c4+! Kc6 2. Ba4+! Rb5 3. cxb5+ +-

It's not even possible for the black bishop to be on that square.

That too!

I let Stockfish 12 run overnight and it finds a mate in 27. Once the pawn queens the search space is quite large. The engine doesn't know that it needs to trap the king to force a move from black, so there is an element to brute force here. Eventually the queen traps the black king, eats through black's pieces, and helps the queen with the mate.

I've solved 1000s of difficult puzzles in my lifetime, but this one will always be my favourite. Hopefully you will enjoy this one as much as I did . And don't even think about running this with a computer engine, I've tried chess.com's Stockfish at max depth 30 and it still has no clue how to solve it
I guess if enough people see this post I will update this with the full solution in a later comment. Have fun! (p.s. I've never tried embedding a puzzle, I hope it worked)
Why does Black's King go c1 and not a2? Us there still # with a2?

This is easy, and you don't even need an engine to find the winning mechanism.
