Best opening systems for beginners to reach 1000 Elo?

hey I'm just wondering what opening systems are the best to learn between 600-1000 elo on rapid and blitz specifically. I've been using the London system for white and Caro Kann for black when white plays d4. however, I've been finding myself in disadvantaged positions going into the middle game against more organised players. what opening systems would you suggest for a beginner like me to make it into the middle game with a solid position. not really interested in gambits as I want to learn better positional play rather than rely on quick exchanges as I develop my chess competency. hopefully this question will lead to some great feedback and discussion for both myself and other newish players at my elo range

Yeah, it's actually a good question.

I'm 1178 in Rapid. I've had a lot of luck sticking with King's Pawn openings as white, it leads to a lot of consistency with the openings lines and can easily progress to the middle game without making any serious errors. As black, I usually go along with King's Pawn in response to e4, and for d4 I go with King's Indian Defense, unless they start doing the London in which case I do 2...c4 to knock them out of their comfort zone.

Really, just pick anything and stick with it.  Then study your decision, but put most time into tactics and end game stuff.  Openings are really the least important part.

When I was your level I played some hypermodern stuff that I didn't know how to play, but my opponents didn't know how to play against it either. When I switched to the London system I instantly gained around 100 points. I think your choice of openings is good. I don't see a reason to change it. Many gambits, especially for white, are sound. Vienna gambit is completely sound for instance. 

I also play the London and KID, and I think that they are both good positional opening systems for beginners.

Imagine losing to a bot with 750Elo

Just don't play the Wayward Queen attack or scholars mate   (I am 1100 rapid)

Wrong question. It doesn't matter what opening people with 3-digit ratings play. Study of tactics and endgames will pay off much more than memorizing a bunch of opening nonsense move orders.

As Black if you wish to begin try to learn the Scandinavian Iceland palmer gambit. This opening will either transpose to Advance French or will continue to mainline. Also I suggest that you check Vincent Moret's book of Chess Opening for beginners. You can also try 4-5 openings in Chessable for free. Yasser Seirawan's Book Winning Chess Opening will provide a healthy overview of almost all major openings. I began with Seirawan's Book and Moret's book. Earlier I learned an opening course from chess.com lessons video on Kings Indian Attack but I failed to handle the position against 500-600 rated players. After reading those books (just began both of these and have finished neither yet) I gained many rating points and went from 450 to 778 (with some winning streaks going as long as 12 games). Then I closed by account for some reasons and stuck with learning and playing offline chess. Then after learning Ruy Lopez Exchange variation from Chessable, I returned to check my strength and found that I could now beat 1000 rated players with ease. Currently I am 1200+ rated. Hope this helps. 

For End game and Middle Game, I believe chess puzzles are enough. You can also go to lichess where they have a very good repertoire of chess puzzles training. I tried it and now my Middle Game is quite smooth. Usually my accuracy is above 75, occasionally I also record 90+ accuracy.

The London and the Caro-Kann are both excellent opening choices.

I've glanced at a few of your losses, and they had very little to do with your openings. At times, you appeared afraid to initiate exchanges ... this allowed your opponent to pursue their plans without any active counterplay on your part.

You also missed several tactics. And you were a bit loose with your king safety.

These issues generally occured in the middlegame - not in the opening.

This might seem like criticism, but hopefully it's constructive (as that is how it's meant). I recommend spending more time on tactical puzzles. Don't just rush through them - take your time. Review your games, and try to look hard at where exchanges, threats, and captures can be made, or were missed.

Keep at it and keep striving to learn. Even though it might not be what you're hoping to hear, I can assure you that your opening choices are not the issue ...

Do Bongcloud it is the best opening in existence.

As white I would recommend the stonewall attack and as black play the Sicilian dragon against e4 and kings Indian defence against d4 and c4 

I looked at 2 recent wins and 2 recent losses. In none of them did you complete development... so it's not technically correct that you're getting disadvantageous middlegames because you're never actually finishing the opening.

In the opening:

 - Place (and usually maintain) a pawn in the center
 - Move your knights bishops off the back rank quickly which means
 - Don't move the same piece twice unless necessary
 - Don't move pawns unless necessary
 - Castle (ideally to a side where none of the 3 flank pawns have moved).
 - Move your queen off the back rank so now there are no pieces between your rooks

And when there are no pieces between your rooks, your development is "complete."

You did this in zero of your games. Named openings (like the London or Caro) aren't going to help you.

The London and wayward queen are good

No, they really are not. Those things only work against dummies and playing them doesn't prepare you to advance and learn more stuff. They put you in a rut where you try to perfect some horrible, limited garbage.

To get to 1000, all you need to do is develop every piece before attacking. Because almost certainly your opponents will not develop 2 or 3 of their pieces while they fully commit to an attack you on move 3. The Kings Indian Defence/Attack is a common recommendation because it develops and is very difficult to slow down with premature attacks. Make patient improving moves and soon you'll have 4-5 pieces in on the attack.

But if you're willing to learn a deep line, the Englund Gambit is devastating under 1000 against white's d4. But don't get too attached. Once it stops working, it stops working hard.

Assuming this is asking about the Englund, I've found at 900-1000 people start knowing the line, and by 1200 everybody knows the line. All serious d4 players learn it sooner or later. The Benoni is a good opening to use next.

Englund isn't lost if they play the line, but there's no need to be at disadvantage from the opening.

I just play the Modern Benoni, basically as long as my bishop gets to b7 I'm happy. If I can get into the Benko Gambit, then I'm in heaven, but even at 1400 nobody plays the main line deep enough to allow that.
