Building an Opening Repertoire

Hello everyone, I have just started to take chess seriously over the past few months and have run into a bit of a problem. In most of my games I stumble and blunder in the opening. I have tried studying openings but I always run into trouble, because i'm not exactly sure what to study. Do you guys have any ideas for a solid opening repertoire. I know I want to play e4 as white and maybe the Sicilian or French against whites e4 but i'm not sure what to do against d4 or any other type of whites opening. Any ideas?

Honestly, I play Sicilian Closed as White.  At least I play e4, Nf3.  I typically wind up swapping pawns and knights about half the time.  Playing white is not as clear cut as playing black.  White can play just about anything.  e4 is considered a more open, situational opening, whereas d4 is very tactical and sometimes closed.  In general, control center, develope knights before bishops, and castle it up early.  Honestly, for advice on playing as black, I refer people back to a thread I created a couple months ago.  The first response has been influential on many players since he wrote it.

Here is my opening repertoire

White

Ruy Lopez

English/Yugoslav attack against all Sicilians except for (I will not even try to spell it (Or much less pronounce it)) 1. e4 c5 2. nf3 d6 3. d4 exd4 4. nxd4 nf6 5. nc3 e6 I play Levenfish Attack

In blitz games I play Goring Gambit

Black

Sicilian, Kan

Benko Gambit

Hope this helps!

Thank you every one for your help ;)

@iSwimmer: Can you list any specific examples of these blunders? If you're simply falling into traps, there's no need to worry. Simply note the trap and make sure you don't fall for it again! As for specific openings, try playing by principle at first, putting emphasis on not hanging pieces, developing all your pieces, grabbing the center, and castling early. If you've already gone past this phase though and are experimenting with new openings, you'll likely run into some mistakes, and that's all right as long as you learn from them.

I play the Ruy Lopez as white when I can.  I am surprised by how many players have picked up the Sicilian defense in the past few years.  When I started playing chess online ten years ago, almost none of the lower rated players played it.  Now that I've started playing chess again, it seems that everyone is well versed in the Sicilian.

I need to add some Queen's pawn openings to my repertoire for sure.

to the OP-

If you are just starting out I suggest

as Black

1. e4 e5

1. d4 d5

Play classical openings. While you may not stick with them forever, the things you learn from them (strongpoint control of the center, development, pawn breaks, weak squares, space) are ideas you will use later in any opening.

These openings have been around a long time so you also will be able to look at the games of the old masters (which will make more sense than modern games in many respects) and you know that you aren't wasting your time with some trash opening that fails the first time you trot it out against strong opposition.

Just pick one opening and play it consistently. You will eventually get used to the resultant positions, and blunder less frequently.
