At first I thought u wrote 400 rated puzzle and I was wondering why u found it so hard lol
An interesting chess puzzle I found on reddit.

Qe3 is a forced queen trade because its attacking the rook. And here, black has a king that is pretty close to the centre also black is 2 pawns up. Therefore, there is a queen trade.
And yea, there is a lot to explore... I don't have all the answers in this puzzle but the two moves make sense.
And Nf2+ just makes the position equal so thats why its a blunder.
So, apparently this is a 4000 rated chess puzzle according to chess.com. Can you find a way to solve it?
Before you click the hint option, consider these hints that I give you.
Hint 1: Nf2+ is not the move. It's a blunder. It makes the evaluation bar equal and loses all your advantage.
Hint 2: You are two pawns up and have a king that can move around with full mobility in the end game.
Also, I myself could not find like a full flegded answer. So, there is a lot to explore in this position. Just saying in case you wonder how this is a 4000 rated puzzle.
