Default Chess problems and studies

Personally I've never been a great fan of composed chess problems ("mate in 2" etc) and composed studies ("White to play and win/draw") preferring practical play, but the world of chess problems and endgame studies is a vast treasure chest in itself. Perhaps we ought to have a thread about them.

I've just been quite taken with the following puzzle which someone posted on chess.com. I couldn't solve it myself and eventually had to look at the solution which someone else posted. The puzzle is: construct a game which reaches the position below after Black's 7th move. According to the poster on chess.com, the composer of this puzzle is Bosko Miloseski, and it was published in "The Macedonian Problemist", 2015.

That's a much better effort than what I was trying, and in several respects you are close to the solution. But of course Black's 4th move is impossible there, so it fails as you say.

the sad part is all it took for me to get to that was analysis of what needed to be done one thing I still haven't figured out is how the king works because black has a bishop and a pawn missing so there has to be two captures the bishop and knight both had to move out of the way to castle the king had to move to allow the knight back to its starting position, and at very least the minimum other moves that had to happen is what is shown.

The study below is by V.Vlasenko, 1967. White to play and draw.

Unfortunately, the puzzle has since been shown to be flawed, and in fact Black wins with perfect play. But White's key first move is still beautiful and would give excellent practical drawing chances if the position occurred in a game.

So: White to play. What move gives drawing chances?

?

I must be confused I don't see a legal move, if the king moves it's in check, the pawn can't move and the knight moving would allow the H bishop to check the king. only move I see left is resign.

The pawn is going the other way, so the only question is, what should it be promoted to when it reaches the eighth rank?

Well, h8=Q doesn't work.

h8=Q Nc5
Qxh6 Nd7#

That is quick.

I'm thinking h8=B or N, the lines are pretty drawish.
