Endgame puzzle?

lnwnl

Black to play and win.
Although he has 4 extra pawns and a piece, he is getting checkmated.

I don't see the 4 extra pawns but I suppose they are up the players sleevewink.png. It looks like an interesting endgame which starts somewhere in the middle of the solution. What's the orginal?

lnwnl

lol four pawns oops

No, it is an endgame puzzle that starts with Kc1 -Kc2/

Arisktotle

That's still weird. If white starts with Kc1-c2 then he supposedly received an instruction to achieve something - a win or a draw. It's most irregular to start and loose whatever you play. May be there is a hidden draw somewhere?

Edit: it appears that 2. Re8! draws but that would mean black cannot win from the diagram.

The book missed 2.Re8! The star perpetual between Rc6+ and Rd4# dancing between c8 and d8.
This puzzle was before engines were around. Bf1 was suggested because of all of the drawing resources White has if Black promotes to a queen.

Clavius

Agree with lnwnl.

I can believe the book missed 2.Re8! but I bet the composition author did not! If he let white start with 1.Kc1-c2 he must have wanted the draw for white. The try with 2. Bf1? a8=B! is the fun of the composition while 2.Re8! always was the intended author solution. If the book didn't say all that then it really missed the whole point. Trashcan nearby?
