I presume that the problem here is to work out who's move it is? This is a possilbe solution, giving...

Well done solving Turco’s problem, but you made a small mistake with Handloser’s. Does black have any other option than c1=q after the rook moves?

Ah yes very nice, black can underpromote to knight, threatening 2... Nxd3 and avoiding mate next move if white queens. So needed is 1.Re1 c1=N 2. d8=N Nxd3 3.Bxb3#

4. Mate in 3 (white to move)

Usually in a study, you need to first figure out black’s next move

Ask yourself the exact purpose of the most obvious move, and then a better move will soon reveal itself.

For some strange reason I had way too much trouble finding the fourth move. Maybe because it looks too normal

Funny zugswang

The obvious move doesn’t work because of black’s bishop. How do you block its path to your main attacker?

Funny zugswang
I wouldn't really consider this to be a zugzwang, but 1.Ndc5 is threatening 2 mates and depending on what piece black promotes to after 1...a1, white will either mate with Nd7-c5-a6-b4#, or Nd7-c5-b3xd4#. 1.Qe3 threatening 2.Qd2# is also interesting with the point of 1...exd3 2.d4# but 1...f2+ spoils the fun and it's mate in 4 not 3.

12. Position after black’s 7th move

I’d put a hint here, but it would probably give away too much. Enjoy

Also, was mainly referring to the a1=N solution when I said zugswang

not sure what problem we're trying to solve here. Looks like white has given up R+3P for N+2P. Kingside looks a little soft if black can get in ...Rh1 or ...Rh2 but just Nf3 white doesn't seem to be in immediate peril.
Or is this another one where we have to re-contruct the 7 moves?
