500 rated players are crushing me at chess.com

I float around 1000-1050 on Lichess, I have 1500 puzzle rating (but it's not like I'm spending much time on single puzzle, It's 2-20 seconds (some I just already know, I played already 1667 puzzles on Lichess + ~200 on chess.com) ) On chess.com I can beat all bots up to 1100 consistently (1300 nelson - I would say 40% wins/60% loses)... And yet on chess.com 500 rated players crush me all the time! I can't escape 500 rating.

I never studied any openings or end-games, but I played enough games to have some feel about simpler openings and I know "solutions" to few endgames.

I always "die" to some ... positional game... Maybe it's because not only I don't know openings but also mostly play puzzles... It actually fits perfectly as explaination... How do I train just positioning and piece coordination?

Problem is studying openings is pretty boring for me and I play mostly for fun. Puzzles are fun, blitz games are fun, rapids are kinda boring and "studying" is extremally boring (for me).. But if there's some "funnier" way... Maybe some website has special kind of puzzles, that don't really rely on capturing but improving position...

Also I play only bullet 3+2. It's because I usually play at work and can't just get engaged in "rapid" game. But this timing fits me well ( I believe) , I got used to it.

Yeah, after looking at some of my last tilt-games on lichess before I came to lose even more on chess.com I think I just throw by trading ok'ish position into equal-material, worse position... And analyzing your own games is interesting lessson (more interesting than learning openings)

Lichess has inflated ratings. 

The 500 will continue to crush you unless you can demonstrate improvement.

Playing 3/2, 2/1 and 1/0 isn’t the way to improvement but if you insist on continuing, just have fun.

What trips me up when training with bots and then playing real people is how much the play style differs. A lot of times I can keep up with my 1400-1700 rated buddies but when playing people of similar skill/ rating I can find myself in extremely unfamiliar positions. Throw in time controls + a bit of panic and my 3 brain cells pop.

Also it's my understanding that knowledge of opening theory doesn't play a huge factor at ratings like yours and mine. Every loss is a learning opportunity, and if you're having fun you literally can't lose, regardless out the outcome!

Thanks for your responces! I think getting stockfish on lichess to create puzzles from games that I just played is the best way to learn. It gives me puzzles that I love, while showing me my mistakes.
