Openings

I have been looking for good openings, but i am confused. so could anyone suggest an opening with the notation
thank you if u help

Stick to d5 against d4 and e5 against e4 as black
As white stick to either d4 or e4
Don't go deep into openings right now
Tactics and endgames are more important

There seems to be this notion that beginners should avoid studying openings at all costs and tactics are the only thing that matters. This couldn't be further from the truth. A solid positional understanding behind chess is necessary to improve. Tactical ideas and motifs make up about 10% of the chess moves played in a game. The rest are positional moves meant in improve your position. @Koo8384 said d5 against d4 and e5 against e4. Say your opponent does e4. Then you do e5. Then your opponent does Nf3. What now? You probably know what to do for at least a few moves, but say you didn't. If you didn't know any opening principles or ideas, you'd be stuck and might end up making a move like Bd6 which isn't the best. This is why it's necessary to understanding opening and positional ideas at least as much as you understand tactics. What baffles me is how much emphasis people place on beginners learning tactics above anything else. The thing is, if you play bad positional moves while your opponent plays good positional moves, your opponent will be the one with the tactics, not you. If you studied all your tactics but little to no positional ideas and strategy, you would be able to recognize all your opponents tactics, but soon they will start to overwhelm you and you will ask where you went wrong. The hard about positional ideas which makes it harder to learn that tactics is that you don't realize you messed up until many moves ahead when it is too late. You never understand the value of castling until your king is trapped in the center about to be mated. Here's what I recommend.

For openings, stick to solid openings-avoid gambits or systems. The problem with gambits is that you are generally going to give your opponent a better position (except for some like the Queen's Gambit) without your opponent having to do anything. The problem with systems is that you are doing the same moves over and over again and you won't really learn anything or improve. You might want to avoid openings with a lot of theory if you don't like memorizing. An example of an opening with a lot of theory is the Ruy Lopez.

Learn all the opening principles and master them. This is the standard stuff like castle, control the center, develop your pieces.

Then move on to middle game ideas and strategies. This is where knowing your opening becomes important. For example, in the King's Indian defense, black's middle game strategy is to push his kingside pawns and attack white's king. If you didn't know this, you would be lost trying to figure out what moves to play. Understand the different kinds of centers (dynamic and locked) and play towards that. If the center is open, move your pieces towards it. If the center is static, start pushing your pawns on the side where you have more space/ the pawn majority (the side where you have more space is in the direction where your pawns are pointing. For example, if you're white and have pawns on c2, d3, and e4, your pawns are pointing towards the upper right. Therefore, you want to push on the right side. Conversely, if your pawns are on f2 e3 and d4, then your pawns are pointing to the upper left and you want to push to the upper left. These strategical elements are imperative to learn and prevent you from reaching the middle game and wondering, "What now?".

For tactics do Lichess' puzzles. If you are ~1600+ in that you are probably good and won't let any silly mistakes like missing a fork slip by.

For endgames, I recommend studying the important ones like king and pawn and the basic checkmates like queen or rook.

@FallenSpectre
I said not to go 'deep' into openings
Besides knowing opening principles goes without saying
That's what everyone learns when they start out learning chess in the form of golden rules

@Koo8384 Well what do you constitute as "deep"? Do you consider the middlegame plan 15-20 moves the start of the game deep because I think it is necessary to know that.

The middlegame plan should be learnt as a summary and not to be memorized as moves
People usually have the tendency of learning more than one opening
And here's another thing to consider-
People who don't know positional chess won't understand opening moves
People who don't know tactics and endgames won't understand positional chess
That's why tactics and endgames are more important at that level

opening should be considered deeply and tactically

and we have to know the principles of the opening.

@FallenSpectre
if u play something out of the ordinary your opponent wont know how to exploit it positionally in the under 2000 rating level.

i tried it out in a couple tournaments opening with a rook pawn 2 squares for both colors(without looking at theory), my performance rating was only around 50-80 points lower than usual.

u only need to know general opening principles.

Lasker gave 4 rules in his "Common Sense in Chess":
1) Only play your d- and e-pawns
2) Develop knights before bishops
3) Do not play the same piece twice
4) Do not pin knights with bishops

All of these have exceptions, but they are common sense.

From the above example:
1 e4 candidate moves for black: 1...e5, 1...e6, 1...d5, 1...d6, 1...Nc6, 1...Nf6, say black selects 1...e5
2 Nf3 candidate moves for black: 1...Nc6, 1...Nf6, 1...d6, 1...d5, say black selects 2...Nc6
3 Bb5 candidate moves for black: 2...Nf6, 2...d6, 2...d5, say black selects 2...Nf6
