Openings have nothing to do with deciding your games.
Aborting against d4

hm? whatever does that mean, of course openings are integral to the outcome of a game
Not at your level. Blunders and missed tactics decide games.
Perhaps insert "1d4" in your interesting name and then people who accept the game will know in advance what to expect?
d4 usually leads to a much slower game, my heart often falls when I see d4 due to this.
Now for the lunatics prowling around here that often feel an overwhelming need to contradict statements like that on these forums: I AM TALKING ABOUT IN GENERAL ONLY AND IN PARTICULAR WITH BEST PLAY, I AM NOT SAYING THERE IS NO SHARP D4 OPENINGS AND YOUR INPUT IS BOTH USELESS AND WRONG.
Thank you.

If someone dont like the oepining the other choose he should learn how too crush it
The usual horrible advice that is given here. You pick openings that get you to a playable middlegame that you understand.

At your rating, knowing opening XYZ in detail means that you will blunder something fat a few moves later, and even that is not guaranteed.
Does that mean I shouldn’t try to learn openings because I’m likely going to blunder something anyway? Also, what would be a good rating to start focusing on openings then ._.

Just now I got white 3 times in a row, and right after I play my opening move (d4) all 3 people just aborted and I didn’t get to play white, and I remember reading on a forum (or maybe a YouTube comment) that it’s not an uncommon thing to do. Isn’t d4 like the 2nd or 3rd most popular opening?? It sucks that I don’t get to play white just because of my opening choice.
Yea, some people abort after certain openings, or even whenever they play Black. Pretty disrespectful. Just block them and move on. Once you get a higher rating players will have more respect for the game.

I think focussing is the operative word. There is nothing wrong with learning a few opening moves and general ideas of the opening. But until you stop blundering frequently the focus should be on tactics.

Yep. It's a thing. Lose control of their bowels and abort the game. It's lame, but that's humans for you. It happens less as you play higher rated opponents.
I would advise your opponents to learn a fun line against d4. It's not like they don't exist. I like to play the Albin countergambit, but there are plenty of other things: Budapest, Benko, KID, Grünfeld.

Haha these 900's are just running away from a basic part of chess they don't understand. They need to just learn how to face d4 and play on.
To be fair though, if my opponent starts with the grob, or f3, I will likely abort.

As a d4 player, I hate other d4 players. The only one's I like are the one's that play Queen's Gambit. I'm so sick in tired of e3 systems and especially the London. It's hard enough getting a Botvinnik Semi-Slav let alone a Semi-Slav let alone a Slav let alone a Queen's Gambit. At least with 1.e4 I can play a French right away or transpose to a Taimanov but it gets really annoying once they play the Exchange or the La Bourbonnais Variation which is like King's Gambit against French. Learn the mainlines.
At least the London on paper is a BAD opening. But it's sadly hard to beat ... In tournaments it is basically a way to play for a draw

without good opening theory how can any reach a good midgame , unless there is luck , ie opponent error , without a good mid game the endgame s generally a disadvantage
learn openings and learn them well , is my view , and i know this goes against common opinion here but it changes nothing , learn openings they are an important part of the game

No.

What if they play not 2, c4 ? Thats the problem with the most fun lines and the one who did ask has more tactical problems than others
It is better too learn the prinipilies of opeings in general and tactics
You can't just rely on gambits, that's true. But if your opponent allows them, you can often have a fun game.
