That's interesting
Anybody Know the Lollipop?
The first move is cool, took my some time to spot the subtlety (say hello to Saavedra). The rest is pretty standard though.
I would have fallen for the trap. Not that I couldn't see it but simply because I didn't expect it in this type of position!

I fell for the trap myself, admittedly! The quiet move after 2...Ka7 was easy, but took a second with the ...Kc8 idea (zig-zag if he repeatedly goes to a6 and b7 until he cannot go to a6 any more)

I know this one, promotion and queen moves are easy, king moves are tricky especially the first one.

Promotion to what?
White to move and win! (Figure out the lines, not just the 1st move)
