Puzzles... Don't let me finish.

It has been posted so many times, but never this exact question, so I'm gonna ask this.
It is more of a rant, anyway...

Why, oh why, puzzles often do not let me finish the mate sequence?

I understand, at certain levels (am currently doing up to 1900+ level puzzles), it is assumed that you saw this mate in 3 after you make the first move (or you made first three moves, and there are two more till mate). And sometimes there are 2-3 variants of how exactly the opponent can react, only to be mated anyway.
But what happens in my case is that, sometimes, I make the right move, puzzle ends, but I don't actually see where the mate is, or vaguely assume there is one, where, actually, a beneficial trade was assumed. I have to open up the analysis and see the scenarios.

Why the puzzle just *does*, *not*, *let*, *me*, *finish*?!

(It also leads to rare situations where I don't see mate in one, make the right move, puzzle ends, and then, myself being puzzled, I load up analysis immediately, instead of looking further at the board. As I assume it is not ended yet, as is often the case.)
Include one scenario, in case there are many, save me the trouble of going through the analysis too often, please!

Also, sometimes, It is the matter of satisfaction, to completely finish a particularly interesting puzzle.

Just my 2 cents...

Idk, sometimes I can't finish a mate in 2, other times it lets me do the mate in 4

Yeah, This is true. i did not say it is always so, but "often". I am glad when sometimes it does have a completed solution.

I just had a revelation that may explain this. Remember that Chess.com puzzles act in a way where there is only 1 move you can play that maintains a win or maintains a draw. Here is my theory:

• In some forced mates, delivering mate is the only winning idea. Therefore, you play out the entire line to mate.
• In some forced mates, you don't have to actually deliver the fastest mate to still be winning. For example: if you have a forced M3 or forced M8 - then you have at least two valid solutions; the puzzle ends. Even more extreme: you have a M1 but you can ignore the immediate mate and still be winning (perhaps through winning additional material); again, you have multiple valid winning moves so the puzzle ends.

This is just a theory of course. If you run into a puzzle where a forced mate sequence is not played out in the puzzle, please link so we can take a look.

I just found an example which confirms my post above. Take a look at this puzzle:

Note that the puzzle ends before Black can play the mate in 1. However, Black does not need to immediately mate White because Black is up material in a good position. Instead, Black has other winning moves.

Nice observation!
Sometimes, though. when multiple ways are available, any but the fastest is labelled as incorrect. Same goes for taking hanging queen instead of mate in one.
It is understandable, puzzles are about the best/quickest solution.

What I am saying, although I'm done with puzzles for today, is that sometimes it does not finish before the choice of mate vs win a queen, or M1 vs M2 but in those cases one move is still clearly better.

I do agree that probably, any case where you could argue that there are two options, they just cut before that.

As per puzzle report prompt: "You should only report problems where the answer given is incorrect or there is more than 1 correct answer."

Huh, there is a saying "the better is the enemy of the good", but puzzles indeed are about "the best".

this also annoys me. You can go to analysis board to see if you want to
