It's difficult to give a short answer, but talking about specific positions (especially those coming from your games) with stronger players will broaden your natural field of investigation.
Looking deeper into a game

I'd say that if your 1690 were FIDE or USCF you'd be intermediate, but the ratings are inflated here and don't nearly equate with FIDE or USCF. We haven't defined "intermediate" to our mutual satisfaction yet either, so not sure we are talking the same language yet if you know what I mean. IMO, intermediate extends to around 2000 or so, then comes some other step like advanced, and so on. A few USCF masters I've talked to say they haven't mastered chess at all and that the beginning of mastery begins at 2300 (and never comes?). So we're all students it seems.
Concerning looking deeper into the game: I think you need three things to make
big steps in the improvement of your game (and see deeper).
1) Ever-improving tactical ability. Spotting motifs and making combos.
2) Exercise power of calculation. Calculate variations, keeping them all straight
in your head, and visualizing clearly many moves ahead. It's like a muscle and exercise makes a big difference.
3) Get chess knowledge, e.g. positional knowledge. Space, color-complexes, etc. Much of the game involves getting the better positon, not just
winning material right at the moment. Knowing lots about positional play will
fill you up with ideas about what you can do in a position. You'll see more
"targets" and you have more to think about--You will be seeing deeper :)
Sound fair?
I’m rated around 1690’s on chess.com which makes me an intermediate level chess player. Players my level are supposed to be studying theory on chess and stuff but I think often I just don’t look deep enough into a game, like grandmasters can. How do you look deeper into a game? What kind of things do you look for?
