What are the downsides of playing the Accelerated London System?

In my time of playing chess, I have had fads on some particular openings. These include the Reti opening, E4, Ruy Lopez and the Scotch game. Currently, I am playing the London System in most games and have found it to be pretty good. What are the downsides though?

At your level you can play whatever opening you want.

OK, thanks 

What i mean by my response is this.  Whatever opening you decide to play should be based on the typed of middlegames you like to play.  Not based on what your favorite GM plays, what you think is "aggressive" or "tactical".  Also keep in mind that after all the time you will spend memorizing moves, and having no understanding of "why" those moves are made.  You or your opponent will be out of book by move 3...4...etc.  Then what are you going to do?

Great points, I am going to remember these when playing next

Downsides: people will use anti-london openings, some people will dislike you lol

There are no objective downsides.

people disliking you is just a side effect

Yep

Guess Im the only wondering what the "accelerated" London system is.

I did have a game where white resigned in 7 moves. I guess better to get it over with then. It would have helped in the one OTB game I played. I chased white's king everywhere to end a draw. I gotta give credit to white....how he stood in there and took it every move.

I took a look at the OP's rating and didnt even concern myself with whatever the accelerated London is or was.

Heres the 7 move game...

(rest of the game chopped as irrelevant).

Your last move indicates that you shouldn't be concerned about the subtle or not-so-subtle differences between Regular London, Accelerated London, Turbo-charged London or Lame Duck London, but rather the absolute opening fundamentals.

Please, DO start from there before focusing on openings- else you will just be wasting your precious time for nothing.

pfren...this is chess.com forums.  Home of the "I learned how to play 12 minutes ago, but im aggressive.  What openings should i play?" 

Here we go: 1 it's not an ambitious opening, Black equalizes comfortably. 2 it's so common that many people are booked up with defensive systems. 3: playing systems HINDERS your chess development, by playing the same moves every time you aren't playing chess, just a joke version of it: you are very likely to miss mistakes by your opponent! Playing systems is one of the best ways to limit yourself as a chess player. 4 :many people will find you annoying and rightly so. 5 :it's so popular that you aren't printing your own stamp to the game, your opponents will remember you as "londoner 1452nd" or something like that. You may have seen GMs such as Carlsen playing it and you probably were inspired but keep in mind that those players have a lot of experience in chess, know a lot of book openings and many different pawn structures which means they KNOW when to deviate from their setup to do something more useful, which you probably don't know how to do. I hope I answered your question efficiently.

That's way preferrable to the "I am really rated at 1800, but it shows as 650 because my mouse is greasy" kind. It's pretty much the same like myself claiming that I'm not worse than Carlsen, because our current score is 0-0.

Why are you playing so many openings? As @pfren and @imbacon pointed out, you have no business learning openings like the Ruy Lopez which have IMMENSE amounts of theory that a novice like you wouldn’t understand.

No understanding of the moves you’re playing either

I think its an online thing.  The only place i see beginners asking about openings in online.  Im assume they think they need to play the same openings as their favorite player and or trying to appear "aggressive"/"Tactical".  Its the same song and dance with  these type of posts.  Beginners and low rated players that apparently were told by someone that openings are deciding their games.  Even though they are playing speed chess and blundering material.

Well, I don't really know about this online only thing. 

When I was in elementary school, my dad kept pushing for me to read some chess openings. He said something about it helping my chess improve (I didn't really listen to him as you can see). I didn't really care to read about chess in elementary school, though, because I would rather just read some novels over chess books. 

Now I am the exact opposite. But I do know that when I made my account, around that time my dad noticed me getting back into chess and told me that I should learn some good openings to make a "solid foundation" (or something like that). I also didn't really listen to him that time, because I was already looking for something fun to play in Sam Collins's "Understanding the Chess Openings" (2015, out of print)

My point is this.  IN PERSON...When someone was looking for caching, I have never had someone come up to me telling me how aggressive and tactical they are, and that they play the Sicilian and know it 20 moves deep.  Now i have had people brag about their over estimated abilities.  But those quickly get shot down once they actually have to play.

This is why i say its an online thing.  Pre covid, I help run scholastic tournaments.  And not a single kid acts the way they do online.  Theo nes that do act that way?  Dont last long when it comes to OTB play.
