Using the Same Opening Every Time

Hi, I'm Helltank, and yeah, I didn't post a "Hello Everyone" message, because I thought it would be better to actually post something relevant to chess as my first impression.

Now the question is this:should I use the same opening every time?

For weeks now I've been using the exact same opening(the two middle pawns two spaces forward and the knights at C3 and D3, or their counterparts if I'm black). Now, you might have an immediate response of "They're going to predict your moves", but for 3 weeks in a row none of them have found a satisfactory counter.

Yes, I know they can easily find a solution on the internet, but they haven't for some reason and I'm not about to enlighten them for obvious reasons.

Thoughts?

You can't have your pawns on D4 & E4 , have a knight on C3 AND a knight on D3 in four moves - sorry not possible!

There is nothing wrong in playing the move you like better every time until you feel tired. Knowing what you're going to play is not such an advantage for your opponent, if not at very high (professional) levels and anyway only in sharp opening lines. Instead having great experience with an opening setup is definitely an advantage. 

I guess you meant knights to c3 and f3, but anyway is quite difficult to play this setup against everything.

Yeah, I meant c3 and f3. Anyway, my opponents tend to make pawn formations which have weak chinks that this setup exploits with ease. Also, it gives me an edge-the moment any undefended pawn near the centre appears, more likely than not I'll be able to seize it.

Using the same opening all the time is a good way to learn all the lines and variations for that opening. After you know the ins and outs of that opening, if you want to start with another opening, then do it. Wait till you learn those ins and outs.... then switch to another. It's a good way to expand your opening knowledge. And you may want to switch to a more sound opening. Might i recommend the Kings Indian Attack or Queen's Gambit as White, and as black play the Sicilian for e4 and King's Indian Defense against d4. With either working for uncommon openings (for the most part)?

 Good idea. I'll learn the Queen's Gambit and King's Indian Defence.

Honestly i disagree almost completely with the suggested repertoire 

I always considered the sicilian a suicidal choice for an under 1800 player (many would disagree of course). Piece activity is everything under a certain level and in the sicilian you are on the defensive and underdeveloped for a long time in most lines. Black has to study the precise path leading to a good position among tons of pitfalls, and only then his position can become active and counterattecking. It's not an opening you should play without great study and understanding, and you must use your time for something more useful than studying theory at amateurish leves.

I think that the queen gambit can lead to positions too complex for the average player and i suggest you to follow the classical advice: 1.e4 is the starting point. Not for everyone but for most players this proves to be the best choice.

In general you shouldn't worry about openings until you reach a rather high level; just play something sensible, develop your pieces, control the centre and you can very well reach a 2000 rating on chess.com without even knowing the name of what you're playing.

There are only so many openings you can play, and all the time you have to consider the variations and the possible answers. You hardly ever play the first 20 moves twice, so it's no problem. If you get tired of an opening it is ok to switch, but really it's ok to do that after a few years. A new player of a certain level needs at least one opening with white + all replies and 2 or 3 with black + all white variations. That is quite a bit to learn assuming it even matters on your level. As a kid I only had a 20 year old pocket reportoire book. Now for club play it's quite enough to know the basic ideas of a few openings.

I can only say do not change your openings too often, you will only be left with shallow understanding.

I tried out Queen's Gambit, and have compared most common answers, from Accepted to Declined(Marshall) and Declined(Slav). 

The only problem is Declined(Slav).

Sicilian... I personally dislike it.

King's Indian Defence sounds okay, but I prefer Grunfeld as white's hand is forced.
