How many openings/defenses should an 1150 rated player have?

Thanks to everyone for the feedback.  It's really helpful!!!  It confirms my suspicion that, at least on my level, "less is more."  Now, a question for the future.  If I manage to eventually achieve a rating like 1600, do you guys feel I should THEN add more openings/defenses, or stick with the recommendations that have already been given in this thread?  THANKS AGAIN FOR YOUR HELP!!!!

I don’t think you should add more openings, because that’s useless. Why have 2 openings with white? What’s the point? I have a pet opening if I ever get bored, but that’s the farthest I’ll go. No point in studying 2 openings when only 1 of them will be useful every game.

I think at 1600 you should begin to study some opening lines. You’ve probably played thousands of games to get from where you are to 1600, so just start to take a look at some common lines and understand the ideas that come from your opening (you’ll probably have a good idea because you’ve been playing the opening, but extra knowledge doesn’t hurt)

Be careful not to focus all your time on openings, though. As mentioned, tactics decide games at the -2000 level. This is just to get you out of the opening comfortably. 

I would like to say that being a master at the Dragon means most likely that your opponent's are masters at the Yugoslav.

Tactics don't decide all games at 2000 level. get to 2000, play a classical tournament, then tell me all games are decided by a tactic.

It's just not true.

Also, learning two different openings is good for flexibility.

 What if your opponent plays a line that you've never seen before? if you were me, I'd take a look at the game and learn the line. Simple as that.

2000 on cc, not 2000 otb

CC ratings are just weird man

also, happy one-day belated birthday lol @InsertInterestingNameHere

I reckon having one opening as white that you're very comfortable with, as well as a defense against both 1. d4 and 1. e4, with the intention of expanding your repertoire gradually as you improve, is ideal. At least, that's what I wish I did when I was 1100. 

I was one of many who blindly memorized moves as a beginner. I tried learning sicilian theory at 800 that no one played into, if you can believe that. I eventually moved away from that crap, and I was better for it. Listen to the people who tell you to not just study openings all day, it’s good advice.

like literally 1 for 1.e4, 1.d4 and 1.c4

and then you wing it till 1800

I don’t study openings. My memory is to bad to memorize lines. But if I play and face something a lot of times it more likley to stick to my memory. So what I am trying to say is that I learn from analyzing my games instead of trying to memorize lines that I have not played yet. I also pick up ideas by watching strong players play on twitch and youtube.

Yep, as people said, one white, two black (vs d4 and e4) is where you're aiming to be. Choose well, and ideally pick something that gives you scope for development, by having multiple playable variations, or transpositions. Remember the first few moves and maybe a specific line or two, you're away. You'll be in heaps of trouble, and learning. 

When you get better I will recommend to have at least two answers to 1.e4 and 1.d4. Then if/when you have one of your opennings temporarily 'ruined' (eg. by a bad loss or a new popular answer) you can put it in the 'garage for repair' and play your second opening meanwhile. 

One of each till you know them very well. Then learn some logical (related,) openings that expand on that. 

I don't really understand this...

For example as black I choose to play 1.e4 e5 2.Nf3 Nc6

This means I have to learn a few variations of the Spanish
A few variations in the Scotch
A few in the Italian
The 4 knights
And be aware of miscellaneous stuff like the King's gambit, Evans gambit, the Ponzioni, etc.

You had 4 black defenses and now you have 2? I have no idea what that means.

But to try to answer your question, you should probably know... I guess half a dozen lines about half a dozen moves deep (?) Which ones to learn depends on what you see most often in your games... after each game compare the opening you played to a database to see what the common moves and options are.

The key is not 'how many openings' but how many middlegame structures you understand how to play. It's fine , if you want to, to play a lot of openings, provided you use them to study the MGs that result. Usually this means you play one for a while, study your losses & grow understanding then switch to another when you feel bored. OTOH, memorizing lots of openings wo understanding doesn't make you a better player or chess more fun. Some people start with the london system and stay there while others experiment for a time, find what fits them, start hitting strong opponents and then hyperfocus. It's a human process so there is no 1 answer for all! --Bill
