Losing to low rated players I’ve been having this problem for a while and every answer on the Internet I see is "Oh just dont be too confident.” But that’s not the issue I have as I try my hardest in all my chess games. I’m rated 1600 on average. Lately I’ve been swinging to 1660 as I practice every day. I regularly crush 1300-1500 players and find my favorite games are against those in the 1600 range because I feel it’s the most even of a match for me.

However, when I play on chess.com (I have an account there from when I first started playing) I’m playing 800-900 rated players, and I easily have a 30% win rate. I cannot even begin to understand why the play I see from scholastic rated players trumps that of 1600 rated players without a single doubt.

This must have some kind of outside source, as when I play OTB chess with actual players who are most likely around 800-900 I have no problem beating them and enjoy sharing with them the good/bad moves of the game we played. 

Pardon the salt, I know losing is part of the game but it feels pretty awful to work really hard and get good at chess just to be consistently beaten by beginners.
Well, if your statistics are accurate (and not just based off games you remember), then there are a few possibilities:

1) The 1300-1500 players you play in OTB in your area are overrated. Or

2) The 800-900 players online are underrated.

Also, if you think you're good at chess but are beaten by these players online, are they really beginners? Online ratings especially at a low level aren't always representative of playing strength.
