Probably the Worst Game that I've Played in a While

This is a 3+2 blitz game that I just played.

From move one to move 26, it was really a normal game. Just a few trades that left me a pawn down, which was fine as I had taken his very strong bishop. 

Move 27 is ok, the engine says that I should have retreated with the queen, which is not a human move, so I don't fault myself for not finding it.

28-29 we trade inaccuracies, then I get a second pawn down on move 30.

A mistake by my opponent on move 31 leads to an inaccuracy by me, then a blunder on my opponent's part. Apparently there is a mate in 4 because of it, which is basically checking, taking a pawn, then delivering the mate with the knight. I did not see this at the time, so if you feel that I am dumb for doing so, well, I did say it was a bad game in the title.

Anyway, my opponent then feels like blundering again, so I am technically up 3 points in material despite being down two pawns.

I do a best move, opponent blunders again, I miss mate in 1 (I don't see why it doesn't say that it is a missed win or mate in 1 in my analysis, but it is. If you want to check that out, it's move 34.

Some shuffling and trading later, it says that I am now down by 5 points, even though I don't do any blunders or mistakes.

Then we both blunder on move 44, really it doesn't change anything.

I blunder a mate in 1 that my opponent doesn't see on move 52.

I blunder again on move 53, I have perpetual check with this move that can make a draw if he plays a bad move. The best move makes this position -63.6 points. My move apparently made a M10.

He makes a missed win trying to stop my draw threat (Really, I threatened to draw with him, how scary.) 

I then just keep checking the king, and somehow it says that I'm blundering a lot because it wants me to take the pawn a square from promotion with my queen. I say no to that, as it would have me losing my queen for a pawn. (I would have used a bit stronger of words, but this is chess.com. We don't do things like that here.)

Anyway, a blunder on his part leads to my having perpetual check. He then proceeds to then have a missed win, I take the pawn threatening to promote, and I am still in this hectic game.

I plant my king on g6, and prepare to try to win his queen. I thought that he was just going to check me out of g6, but blunders a mate in 1. At the time, I thought it was just a move that would win the queen but it was a M1.

Anyway, that is my worst game that I have played in about a year. Feel free if you want to point out more mistakes in the game so that I can avoid this fiasco of a game in the future.

Send your opponent a Thank You card.  They threw away an easy win.
