Personally, I think you should play what you enjoy playing -- assuming it's respectable (which everying you listed above is). Don't waste your time with silly and unsound things like the Grob (1. g4). I also think you're on the right track spending your time on tactics and endgames. I'd suggest spending a little bit of time annotating master games. For the latter, pick games in the openings you play which will help you not only learning your openings but also with the middle games and endgames they lead to.
Also, keep in mind that you don't have a complete repertoire listed there. On the White side, you need something against the 2... e6 Sicilians, the French, and the Karo-Cann (maybe the Panov-Botvinnik Attack against the KC if you like to attack). Eventually you'll learn a line against everything else, probably in annoyance after getting clobbered by it the first time you see it.
On the Black side, you might want to swap the Nimzo for something you'll actually get to play. I had the Nimzo in my repertoire for months in CC games here, and never got to play it once. Lots of QGDs, QIDs, Bogos, but not a single Nimzo. If you like to attack, the Kings Indian might be more to your liking anyway since the Nimzo tends to be more of a positional sort of affair -- and there isn't anything to stop you from using a basic KID setup against anything except 1.e4 (and even then you could play the Pirc or Modern). Also, you'll need something against the English (1. c4) -- and you'll pick up something against the various other off-beat things White can try as you go.
Good luck!




The beginner is me...
I've dabbled for quite a while but never seriously. Now I'd like to begin my chess "career" in earnest. I'm probably @ Class D. I want to settle on an initial opening repertoire so that I can then focus more on endgames and tactics. The openings I was looking for would, for the most part, give me good tactical games while showing me a variety of positions. I think I've settled on the following:
WHITE
King's Gambit 1.e4 e5 2.f4 exf4 3.Bc4 --I do like to attack
Bb5 Sicilian (Rossolimo & Moscow) --the moves feel right to me
BLACK
Alekhine's --ok, I like being different too
Nimzo-Indian --for a variety of situations. (And a good rep.)
What do you folks think? Am I biting off way more than I can chew? I need something that I can count on for a couple years, anyway. Any comments are appreciated.
