I don't understand why the suggested move is best and my move was a mistake

chess.com does have a feature to upload game and positions.  Its the little icon of the chess board.

There's nothing wrong with asking a question when you're confused, but you would be much better off if you made an effort to figure things out for yourself before you ask for help. After you play Nxe5, you can't just look at the board and say, "Look, I'm a pawn up!" Black has a move too! Did you look at the position after Nxe5 and ask yourself if Black had any threats? Qxb2! Forking your rook and knight isn't hard to see--if you look

Thank you for the detailed explanation! Also, I didn't see that chess icon on my phone, my bad will use that from next time

Yep didn't see that! Not that good at chess, trying to improve. Thanks for your input

I also see another problem. You put two of your pieces next to each other and in the reach of an guarded pawn. If the black Lady would not be there, that piece placement would be a great mistake. Let me explain it: Have a look at the picture:

Black on the move woul get a full piece with f6. It is not the case in your game, because white has the resource of playing Nc4 with a threat on the Queen. So the Knight and the Bishop could come away. But it is always dangerous to put two of your own pieces next to each other with one square left if they are in the reach of the enemies pawns.

"Yep didn't see that! Not that good at chess, trying to improve. Thanks for your input"

Yes, it's a hard game! I hope I didn't sound too harsh! If you want to improve, one of the best ways it to always try to look one move--or one half-move--farther. If you see a move that looks good for you, try to look half a move deeper and see if your opponent has a strong counter! Keep trying that and you will see your results improve

It's annoying to be a beginner and miss some things that you will soon be able to spot easily. Don't worry, you'll get there, and the most important thing is that you're asking questions and finding ways to improve efficiently!

Personally, I also find it annoying that the game analysis isn't capable of decently verbalizing or showing the reason that one move is better than the other if the real effect (usually captures, sometimes positions) is several moves away. It takes a bit of time to go through the suggested moves and figure out how one line of moves is better than another, and moves can look identical until you either learn a bunch of rules-of-thumb or look 5+ moves deep into the analysis.

This is precisely why as good as engines are they do not explain "why".   That is where i chess coach comes in.

"I also find it annoying that the game analysis isn't capable of decently verbalizing or showing the reason that one move is better than the other" 

In a real sense, the moves are the "why!" Your will chess will benefit quite a bit more from working through the moves rather than  being given a simple verbal explanation.  You have to learn to see the tactics

I agree. A question, why does all your text have white margin and padding?

I agree with your statement 100%.

I no longer play on here,  except daily games with my teacher.  My rating went from 600 on here to 1317 on the other site that not to be mentioned, and my puzzle rating is 1447.

Chessable is also an extremely priceless investment in time and money.
