Help with Computer Analysis

I won this game but there were many blunders and mistakes from both sides.I got to know about them only after I submitted the game for computer analysis.After seeing the analysis,I could understand the blunders.
But I do not understand the inaccuracies shown by analysis.

a.)How is 6th move suggested by analysis better than what I played?
b.)Why analysis suggests 2nd move which starts with exactly the same move as I played?Does it do that to show what would have happened?

Can someone help?Thanks.

I think what it is saying that black could have used his d-pawn to force your knight to move again, thus gaining a tempo. It recommended instead that you take with your pawn.

The analysis takes two lines. The line that starts with the move you just played attempts to demonstrate why your move was innaccurate. The other line shows how play could have gone if you had made the recommended move instead.

Thanks dawgface.That was very helpful.

That is right Evasan.
