Something interesting I found while reading a book about the beginning of chess composition.

Not too difficult. Black only makes forced moves.

No, not too difficult. It was made by Otto Blathy famous not only with his mostrous chess problems (mate in 100+) and studies but with his inventions in engineering.

Okay, here is another from that period (around 1920's) by another author. Pawns only:

How about 1.Kf2 Kg4 2.Ke3! h5 (h6) 3.Kf2 Kf4 4.Kf1 Ke3 5.Ke1 f2+ 6.Kf1 h4 (h5) 7.h3 (h4)=. Looks a bit simple, but I don't see how else Black is going to make any progress. The idea for white is to make black use his h-pawn tempos first, so that he doesn't get zugged into playing Kg2 later.

Okay that was easy and as I see from your solution not very correct 😉 The author was Grigoriev famous for his pawn studies.
White was supposed to play 4.Ke1! after 2...h6 but I really cannot see a difference.
Okay, another piece, this time however the question is:
Can White draw? :

You gave up too soon! It appears 4.Ke1 is indeed forced.

If 4.Kf1?? Ke3! 5.Ke1 f2+! 6.Kf1 Kf3! wins for Black. White is forced to move his h-pawn.

Okay let's see:
7.h4! and now what? 7...h5 stalemate; 7...Kg3(e3) 8.h5=; 7...Kg48.Kxf2=

I don't have all variations yet, but I believe yes,white can draw with 1.Bg7 Rh7 (otherwise Bxd4+ and the fork on c6) 2.Kg4 Kxa7 (to be analysed what happens after other moves) 3.Kh5 Nf5 (Ne6? but I think that too will draw) 4.Bxb2 Rxh6+ 5.Kg5 Rh2 6.Be5 Rf2 7.Bf4 Nd4 (only move to escape from Be3+) 8.Be3 and black cannot get out of the pin without losing the knight. He can try 8. ... Rf5+ 9.Kg4 Rd5 10.Kf4 Kb6 but that won't help 11.Ke4 Kc5 12.Kd3 Rd6 (or other move on d-file) 13.Kc3 etc...

Anyone helps for the other variations?
