Aftergame Evaluation vs Analysis and Missed Win.

The post game screen sometimes seems really inconsistent with the actual analysis.

It shows 1 mistake, 1 blunder and 1 missed win. It also says great Comeback.

Looking at the analysis however shows 0 mistakes and 0 blunders, and the biggest advantage white had was +0,47 so it seems weird to rate it as a comeback. That's about the advantage that white starts at in the starting position.

Lastly, it's probably because I suck at chess, but I don't understand that missed win at all. My move does waste time and after the best line, there is a considerable advantage for black, but no inevitable mate or the start of a mating net, so I'm not sure what I'm missing here or if that missed win label is faulty. Here is the game and the missed win at move 9. https://www.chess.com/live/game/3524437380

you missed a hanging piece

"missed win" does not mean a missed mate
Its a missed move to win a piece

as BadDobby said
you missed to capture in the Knight in b4

Well yes, I didn't win a free bishop or knight, but that's just a blunder or mistake, wouldn't a missed win be missing to win the game rather than material? At least in German it says something that translates to missed victory, so it's referring to the game. In that case that it refers to winning material, the translation would be faulty.

I see, so it's referring to missing to gain an advantage that would be winning with perfect play? In that case the German translation seems off as it's stating "missed victory"

The initial analysis that the game runs is incredibly quick and doesn't study the game very deeply.
