The title should be how o get a bullet rating 1800 and show you how. Getting a real otb rating of 2000, only a 2000 uscf or fide can show you how not a online bullet rated player.
My peak OTB rating for USCF is 2000, and back then you couldn't get a FIDE rating unless you were 2200+.
I guess that qualifies me, so....
1. Put your pieces on the right squares
2. Stop hanging stuff
As for openings, it never hurts to start building a repertoire that you will never have to change, but without technique beyond memorizing variations the repertoire won't pay off. Where it will pay off is as your rating goes up you'll find that you don't have to rebuild your openings because they won't be getting busted early.
At my level " otb expert" you are correct opening repertoire is important, there is no way I can avoid studying some opening to be competent against experts and masters; but I see experts and masters choke in some tactical situation and badly play the endgame and for me to go forward I need to be more competent in tactics and the endgame to become a master. I relaying this through experience but not some fantasy generalization.
Either that or you need better positions to begin those middlegame and endgames.
I find that every time I plug up a hole in my opening repertoire that my rating goes up because I wind up stealing rating points from those who play that line.
At expert level I can get a playable middlegame against master (2200-2299), but against the very strong masters 2400 elo I get crush, its not the opening but their deep understanding of position, they always beat me badly in the early middlegame or outplay me in endgame; against low masters and experts I have no problems holding my own. I have not done enough analyzing complex positions, to develop calculation skill and assessing position correctly, every strong master have done this to develop to their chess strength. To beat a very strong master you need to be very competent in the endgame and tactics, good endgame help you to plan better, which pieces to exchange and which to keep, what acceptable weakness to allow and what to avoid, and if you need to sacrifice material to keep your piece active, a strong master know this and beyond.
