What is best to focus on when you are 1700-1800 Advanced?

I dunno really i do a bit of everything but what should be main?

OPENINGS | MIDDLE GAMES | ENDGAMES

Advanced Players meaning. Because apparently 1700-1999 is tha

Tactics are most important. then edngames and opening.

no

look over your games. If you're getting out of the opening with a -2 or more disadvantage too often then it's probably time to find a new opening. If you're losing too much in the middlegame you should brush up on tactics and learn strategical play. 

I highly doubt that your endgames are bad

middle game tactics are most important

no it is not. Titled players are considered Experts. i would really appreciate it if instead of insulting ppl you would do the research instead of being an a**

Thanks bro.

Also btw @LaryMulya I am using chess.coms way of seeing ratings.... Above me is still Expert, Pro, Master, Legend

I am not being arrogant and I was asking for advice....

advanced doesn't necessarily mean master. 

facts

Crunch down on openings that’s what helped me, you should be drawn or winning by move 10-15. Then focus on middle game themes and tactics. I didn’t focus on end games to much and it lost me some games so learn that too but honestly middle games and openings are the most important things.

Get a coach

i know 1600 uscf people who have gotten to around 2500-2600 bullet. A guy I'm friends with isn't even a master and has 2500 bullet rating. 

I'd say that calling yourself a "2500-2600" expert may be a stretch, maybe a normal expert(2000-2199) would be my guess.

Hehe

Then you're a fide cm. Maybe getting a GM coach?

1700-1800 is not advanced but crap. I know it because i am in that category(blitz and rapid) and my chess knowledge and ability is a joke.

Saaaaaaaaaaaaame...
