nice and easy!
AMAZING puzzle, incredibly difficult.
Sort:
lol
what about Nxe8? if RxN, then Qf5#, if black doens't take but plays any move, the e file will be unguardad. so white can play e3#.
what do I miss?

The point of the solution is that the hardest black move to deal with is Bg5.
Basically any first move other than the solution, black will play Bg5.
Which is how to solve puzzles like these by the way... pretend it's black to move to figure out which moves don't instantly lose.
Black to move only has 2 moves to avoid immediate mate. Bg5 and Re3. So to find the solution you merely find the move that can mate after either of those. (Not that it was easy, still took me about 5 minutes).
If you wish to see 22 mates, check this version ....
But I personally prefer the version with just 20 mates and only one, efficiently placed, white knight which also delivers the great new try 1.Ne4? ....

why couldn't the rook just move two squares up and say #?
That's what I thought at first, but then I realized that the bishop on d8 defends the h4 square...
I got it in one go 😂

White to move and mate in two.
I'm not going to try to claim the glory for this one, it was composed by T. Taverner in 1881. I'll be very impressed if anyone sees the solution.
See move list for all 19 variations... Nice I found it when I looked how all balck moves leads to checkmate except of Bg5 and Re3. I looked how It must be checkamte then. Qh2 # and Bh2# are the only possibliblities then. So I must make space for the Queen and Bishop . Rh1! nice.

That is one of the tricks of the solver trade!
Technically, the analysis based on the assumption that white "passes", is called "set play" in problems. In games it is classified as "identifying your opponents threats" which is equally valuable.
Not sure why this is hard. Got it in one but maybe I was lucky?
I have seen this puzzle too.
I've seen even harder. It's called getting rid of trolls.
