How is this the best move and not a blunder?

"Threat to win a pawn"? I'm loosing a knight! I've checked out the suggested moves and they make very little sense - I can take the b pawn and pin the knight, but really didn't find any good way of capturing it, plus the pawn on a 6th file is a lot of trouble...

When would you accept a draw?

Opponent declined draw when I was up 3 points of material. Declined again after I was up 5 points of material. Why? I offered a draw because I got a notification reminding me of my appointment so I wanted to get out of the game quickly without resigning. I figured he would accept. Would you accept the draw? I ended up winning the game a few moves later and had to rush to the car.

I’m not so much a beginner anymore more of a lower intermediate (that’s what I like to tell myself at least lol), but proud of this nonetheless
