It was a 5-min game, and stuff was hanging. If you're aiming to work on your "thought process," don't play blitz.
what am i doing wrong fundamentally?


Pattern recognition is the thing you probably want to work on. Do tactics puzzles, also sometimes you put your pieces on bad squares and had to move them again.
You shouldnt expect to crush someone 50 point below you, anyone within 100 points of you is more or less equal.

Well i recall beating 1300+ players so when i noticed opponent's under 1000 rating i thought it was gonna be super easy but i ended up struggling.. Any major tactical mistakes anyone notice? Was my move 13 a mistake? Should my move 27 have been pawn h5 instead?

You aren't doing one only thing wrong. You're doing all right: you're getting closer to chess and beginning your apprenticeship. The amount of "technical imperfections" in our games, when we are beginning, is so huge that no one can help us with brief specific comments. A good route would be sign for a premium membership in chess.com and study many many hours the courses in Chess Mentor, as I'm doing for months. Books, DVDs, will help you with the fundamental possibilities of understanding advices and comments in chess. Even to reach the level of beginning to understand comments on our games is not that easy too easy: takes some time and effort.

For instance: your move 15 bxc3, I suppose is something an experienced player (I'm not in such class) would never play. They would think this way, I suppose: why should I close a column already open, that I can occupy and dominate, bringing my sane pawn in b2 to c3, where it will become a "backward pawn", a weakness... and the like. In order to understand all this, you should get acquainted with such concepts as open column, semi-open column, pawn weaknesses, backward pawn and so on. Almost every other move deserves extensive comments, including in them many more fundamental concepts, I suppose.

hmm i'm all up for critisism and hope my post won't come out wrong:
@bemcertinho i've been playing chess for 15+ years. I have my moments and i've beat plenty of coffee shop players but generally i'm not very good. I'm looking to improve. Yes we both dropped queens but i don't care about that cause if it was a 15 min game that wouldn't have happened. But my strategy and fundamentalls would have still been bad. I think a paid chessa count might be a good idea i'll check out the mentor section, thanks.

Still not sure why you're talking about strategy and fundamentals regarding a blitz game...
It's also a game where a mouse slip was a large factor (or should've been).

Blitz chess is fun, and you may get better at it, but it won't help your overall game. Standard time controls, or turn based play is the best way to improve. Blitz is wrought with blunders, and impulsive moves. Better to learn the game the right way, then come back to blitz later when your strengt is over 1800. Anyway, check my website on my profile, in the "about me" tab. I have a free online video lessons course that shows you what you need to do to improve your game. You will get lots of advice how to improve your play, but I have the methods down to maximize what you need to know and fit it within your avaialble time. My program shows you what you need to do to reach my level, master. I know it works, this is how I did it!

Hm, those messages are beginning to seem a bit preprogrammed...
Maybe the yellowish tint means that it's an ad.

Even playing 10 minutes games, I came to the conclusion that, in order to improve playing them I should strengthen my fundamentals. In rapid games, not too too rapid, I think we need to know the right guidelines and apply them quickly. If, playing quick games, we gather the whole information to feed our wisdom in applying the sound guidelines to our moves, or not, due to the speed of the game is another question. Sure, bullet chess is a bizarre muscular activity, fundamentally. Nevertheless, check, discovered check, open column, weak pawns and the like work in the same way, whether the game is a classic long game or a rapid one, I tend to imagine.

I don't.
Only if you've thought the stuff up before (in slower games) can you use it instinctively in blitz.

wait haha are you saying i'm an ad? I wish. Not sure what I would be selling.
I played chess for my high school team back in the day and have been playing socially on and off for years. Had no idea I sucked that bad until I got a chess.com account. The interweb has a way of reminding us how ordinary we are :)
Hey everyone here's a game I played this morning. It was a 5 min game. The reason I'm posting this one is cause even though there were a few obvious blunders my oponent's rating was smaller than mine and I was hoping to crush him, yet I struggled until the end. I have a feeling my thought process is totally wrong, i'd like to change the way I think about my moves instead of memorizing openings. I'm hoping to hear from 1500+ players! Thanks in advance. PS he had a few seconds left on the clock so he resigned.
