Why is using the pawn to block the attack on my queen better than developing the knight and blocking the attack?

I know the pawn kicks the bishop away and gives me tempo but isn’t development better?

Can you find the mate in 4 that I missed? White to move.

I preceded to find something very similar 10 moves later after me and my opponent were dancing around.

I (black) decided it was safe to take back the knight with my queen. Can you see what I missed?

My gamble paid off

Can you see the mate in 3 my opponent fell for? I played white.

Excuse me Mr. "Analysis" coach, but I had a COOLER way of getting checkmate. 😎

I thought, wow, a fork, and then..
