Knight on the rim not dim?

The computer says that it is the best possible move for my knight. I knew it but don't really get why it just felt like a really strong move. Then I kinda didn't know what I should do with it next and wanted to pawn move but couldn't make sense of it so took instead because that made sense because of the positional value and bishop value.

I am playing black by the way

Knight a5 is good for some reason? And then I triple the pawn stucture

it seems like white was the dim one this game

The black knight went to the rim for the specific purpose of trading off for the white bishop which white could not prevent. Although beginners are taught knights and bishops are both worth three, in an open position or position that can be come open, bishops are generally worth more, especially if one has both bishops. So trading a knight for a bishop is often good, although at your rating level it hardly matters. At your rating level, whoever blunders worse loses. Anyway, traveling to the rim for a specific purpose ensured that it wouldn't get stuck out there with nothing to do so this was an exception to the knights on the rim saying.

I guess that's why it makes sense. But there's more to it than that. I really felt the best move was going to be a pawn move and when I reviewed it I was correct. I never did it because I just couldn't understand why I was thinking this. Knowing what you already said to be true and that being my plan I did that because it was simple and made sense.

Also I don't play chess for rating per se. I mostly play for fun. Given that fact my rating is somewhat inaccurate as I only really play unrated so I can do whatever nonsense without consequence.

Yes knights are best in corner squares a1 a8 h1 h8

After the night reaches the rim pawn to c5 is definitively better because it allows for much more tactical advantage. The bishop becomes active potentially blocking the king's castling and is in a really powerful position. Trading is equally good ruining the pawn structure though I like the bishop better.

I figured this out with some of my friends help

Moving a Knight to the Rook's file isn't always bad. One of my favorite lines (as Black) in the King's Indian Defense is the Panno, which often involves moving the Knight to a5 and then just leaving it there (not trading it off).

I'm going to be honest. That position looks inherently bad at first glance but I don't play that line. Seeing it makes that knight look like it's heading for an outpost mid game and looks strong potentially. C4 probably shouldn't take because of the knight threat with the added open file for the rook. The more I look the more poisoned that piece looks. Better than that you can break with e6 when ready too. That looks like a fun line.

Here's a rated match game against a 2075-rated player:

Why he didn't take the knight?

hi

Couldn't take the night because of danger levels. It was set up as a trap. The bait was taken and the queen was struck with a bishop because of this the horse could not be taken without losing the queen. The Queen moves and you have won a free piece

My game? The white Queen was attacked by BOTH the Knight (on e4) and the Bishop (on g7). Taking the Knight loses White's Queen.
