When the game review says you both played like 100's. I mean that definitely argues that it's a very bad game since you're both rated about 800. But yeah your mom was right about preventing a fork by going d5 on move 4. White was threatening knight to f7 forking the rook and queen, and king cannot take due to bishop protection. You should hate f6 because if that queen goes to g5, it's forking a pawn and a knight. Whichever one white protects, black takes the other. On turn 12 d3 was not the move for white as you say because knight takes d3 is a free pawn. Only thing that can take the knight back is a queen, then white is giving up a full queen and a pawn for a knight and white loses on the spot. Long castle is not a hard move to find. We're 13 turns in and your king is in the center of the row. Get it out of there!! Also you get the rook instantly backing up the queen in a down the middle attack. You also don't sacrifice the bishop because after a queen trade, the rook that's meant to long castle takes a free rook with check and also wins a free bishop. You're literally trading a bishop for a rook and a bishop. There was a lot of badly timed development. I bet anything she has a bad case of finding the right move one turn too late, and still making the move, even though it's no longer even good. This is not the worst game ever played. If you want it to be a true argument for worst game ever, it needs to be a stalemate. I recently saw a game where black stalemated white, and white had 7 pieces left!! Both players were rated about 1900.
naaah man that kinda feedback is how we got a bunch of creators yelling at me with "HEYEYYYYEAAYY WHATSUPITZYABOISQUEAKSTREAMER9000 AND ITS TIME TO BLOW UP THIS WHOLE BUNCH OF TNT IN MINECWAFT" in the first 5 seconds of any video. Just find a good middle ground Halsy.
