What openings should I know as an 1300 Elo rated player ??

I'm a 1300, I play most of the time Caro, London, Sicilian etc. I want to know what openings should really a 1300 Elo rated player should know about..

How far do you know either the Caro Kann or the Sicilian?  When do you generally run out of moves?  How about a Queen's pawn response?

1.e4 e5 2.Nf3

You have to know opening principles as well.

At your level, the biggest limiting factor is likely tactics. If you don't deviate from theory at move 3, your opponent probably will.

For each of the openings discussed in the (3-part) video above be sure to pay attention to whether they are referring to White or Black’s perspective. Also, they frequently refer to some openings as "garbage" or "bad", etc., but these qualifiers are used in the context of how appropriate or advisable they are for beginners. For example, an opening they refer to as "garbage" (an unfortunate choice of words) for a beginner may in fact be reasonable/playable for higher rated players (Intermediates, titled players, etc.)

Anyone who says we shouldnt be learning opening at "our" level is an idiot. Gee i love wasting 6 mins on move 3 cause someone played a sideline and i dont know if im walking into a trap. I split up my learning with endgames tactics, 1 rep for white, 1 rep for bla.ck agaist e4 and 1 for black agaist d4. Keeps me pretty busy. I basically just study and play a few games on the weekends now. How long is someone just suposed to do puzzles ? once they go from 800 to 2000 and now finnaly they have been granted access to learn the italian game LOL As for white i just play 1c4. Atleast theres a "well what the hell do i play against this" in my games ...gets good results

I like to play the Catalan, Queens and Kings Gambit mostly as white - I really don't know about black, maybe Petroff's and Scandinavian Defence: Blackburnt-Kloobooster Gambit?

and how exactly will this stop you from falling into the trap. It’s not like you studied the theory for that specific trap line (since you don’t know if you’re going into it or not), and you can’t exactly atudy all possible trap lines in chess. It is not pointless to learn theory, it is pointless to learn too much theory, and if you believe otherwise, idk what to tell you.

Good to hear of another c4 player!

Not too many of us around these days.

I think people misunderstand the advice. Learn theory. Neglecting openings is bad. You need a basic understanding of an opening at your level. But don’t spend 30 minutes committing the “13.bb8 poisoned pawn candy cane variation” to memory, when the chances are you’ll forget it anyways, because no one will enter your prep. Learn a few practical lines, not advanced stuff.

I follow this plan from WIM @TijanaBlagojevic:

If you play the Caro-Kann, the defense Scandinavian already. Example : 1) e4-c6 2) d4-d5 3) exd5-Qxd5 4) Nc3-Qa5 and you fall back into "the baseline" of the Scandinavian ( 1.e4-d5 2.exd5-Qxd5 3.Nc3-Qa5 4.d4-c6)

Pirc Defense because for example : 1) e4-c6 2) d4-d6 3)Nf3-Nf6 4)Nc3-g6 you fall a game look likes Pirc Defense.

Otherwise for "chess culture" there is an often unknown mouvement that I saw played by a strong bot and is not really or so weak in blitz, it is 1) e4-c6 2) d4-b5  (you have just to try to play against strong AI with the whites to have ideas how you can play this)  

A Solid Opening which is kinda perplexing is the Saragossa Opening..

Does anyone play this - I played it against bots and it seems 2 be solid - I won

True story, I accidentally mouse slipped 1. c4 and hit c3 lol. Had to play it out. I blame it on being drunk.

I once mouse slip the Sicilian for c6 and got stuck with the Caro-Kann haha.

I looked at your profile, you've made such excellent progress over the last year. You must have learned a lot since you posted this.

++ None at all. Just play and analyse your lost games. You will accumulate experience.

oh bruh this is from last year

Should know the general theory and plans for white and black in each opening you play so you can see the context of why moves are happening and identify if there is an error you can capitalise on. It is not necessarily memorising lines just trying to improve your understanding of the positions you intend to play. That is what I am working on now. Still practicing tactics, drills and endgame. Finding the why behind pawn structures and piece placements is my current method for learning chess for the whole game. Hopefully should see a general improvement in play and results in the future.

I think Maybe just find the opening that is right for you - like for me - the Catalan https://www.chess.com/analysis/game/live/48372669113?tab=review

I play some variations of Pirc and Black Lion which are kinda fun.
