Question on Best Move Suggestion by computer

Hi,

I have the habit to always do an analyses of my games to have a look at my mistakes and check the best moves. Quiet often I just don't understand the reason why a best move suggested by the computer is so good; in stead sometimes in my opinion it is just not a good move (but I am really not so good at chess). Therefore would like to open a topic for posting questions on best moves suggestions by the computer so that higher ranked player can explain why a Best Move suggestion is so good.

In my case I have a best move suggestion (with a Critical Move) like this

I don't understand this, because to me black is getting the Knight for free using the pone on f6. My own move was Nd2, which was considered a mistake by the computer.

Can anybody explain why Nxe5 is such a good move (and in fact the only good move)?

Regards

It looks like you are winning a piece with

15 Rxg8 since the rook and bishop work together.

It seems like a good idea to get the piece back. It looks like you end up a pawn up. It's good to keep following the computer moves for a couple of moves to try to understand it. 

Next time, it would help if we had the whole game, so we knew what was on e5 to begin with.

Yes, you end up much better than with your Nbd2 move.

Hi notmtwain,

Thanks for your quick response! Sorry, this is my first post. This is the whole game:

1. e4 e5 2. d3 Bb4+ 3. c3 Ba5 4. Nf3 f6 5. Be2 a6 6. O-O Bb6 7. d4 d6 8. dxe5
dxe5 9. Be3 Bxe3 10. fxe3 h5 11. Qxd8+ Kxd8 12. Nbd2 g5 13. Rad1 Ke8 14. Nc4 g4
15. Nfxe5 fxe5 16. Nxe5 Be6 17. Ng6 Rh6 18. Ne5 Nf6 19. Bc4 Bxc4 20. Nxc4 Nxe4
21. h3 g3 22. Ne5 Nd6 23. Rf3 h4 24. Rd4 Nc6 25. Ra4 Nxe5 26. Rff4 Nd3 27. Rxh4
Rxh4 28. Rxh4 Kd7 29. Rh7+ Kc6 30. h4 Re8 31. h5 Rxe3 32. h6 Re1# 0-1

At bit embarrassing, since I lost and I had a missed check mate, so I could have won:-( Anyway,

About the Rook on g8, I guess it needs a bit further analyses? You mean, after black gets my knight with fxe5, I can move my Rook Rf8 (check). Then he has to move his king, after which I can attack the Knight on g8 with Bc4? I don't see immediately see how I get the rook on g8

Oh now I see I can even play your moves ! Wow, thanks a lot! Now I see, exactly what I thought. I can check with the Rook, then move by Bishop to attack is Knight and gain a Rook. Amazing that you could figure out all the preceding moves. Anyway, now everything is clear. Honestly, I now understand why this is such a good move, but I would never had figured this out during a 10 min game. Time is always my greatest enemy.

Thanks a lot for your explanation!

this is a critical, i dont really know what it means but im sure its not used

Thread was originally from 2020, chess.com might have changed their analysis engine and how they report it to us since then. Based on the discussion, it looks like the dark-blue Great Move has replaced it?
