Best Black Opening for London System Players

Hey, I have been playing the London System for quite a while and find it very comfortable as it seems both solid and gives white a lot of attacking opportunities while not getting too messy. However I am yet to find a good opening with black, Have tried Caro Kann but that didn't work out, Have tried The French but that seemed very neutral and also have been playing the King's Indian Defense but that is very confusing because it King's Indian for d4 and Pirc for e4 and It's just hard to learn and know everything. Can you suggest to me something which is fun to play and Similar to the London System?

you could try the scandinavian and if white play 1. d4 play the queens indian

If you cannot understand the difference between the Pirc and Kings Indian and the differences in ideas between the two, then you do not understand opening concepts and therefore are not ready for opening theory.

Can you answer in words why the Pirc and Kings Indian are nothing alike?

The answer is simple.  The main difference between the Pirc and Kings Indian is White's c-pawn.  With the pawn on c2, in the Pirc, the moment the c3-knight moves, like maybe after f3, the c-pawn can protect d4.  The d4-square is not weak in the Pirc.  However, with no pawn on c4, moves like b5 by Black are easier to execute and especially if White plays f4 or Nf3 instead of f3, the b-pawn can dislodge the Knight on c3, leading to an attack on the e4-pawn.  In the Pirc, e4 is White's weakness.

In the Kings Indian, with the pawn on c4 and not c2, moves like b7-b5-b4 are almost impossible.  Also, with e4 and c4 played, d4 is weak, and hence moves like e5 by Black, and often looking to lodge a knight on d4.  The attack is not on e4 because fxe4 allows Nxe4 and an outpost for the White Knight, hence f5-f4 instead.

If you cannot see these differences, you are not ready for opening theory because those are the BASICS of the opening.  What are you doing studying deep theory of any opening if the basics of those 2 openings confuse you?

Black always has to respond accordingly to the oppoenent threat and variations white choose if u play London I assume your chess dynamics are dead and there is no opwni g for black with dead dynamics as far I know

Therefore in order to play and learn an opening for black first fix your repetoire and stop playing system for God sake 

When u can do this you can try learning thhe najdorf and grunfeld but keep your eyes open as they are the most dynamics opening for black ever existed so your basics must be clear

thats great advice but i wouldnt say najdorf or grunfeld, also the london system has plenty of dynamic play if you know the right lines

But not a opening to be frequently played and i am not saying this this is said by all top grand master 

It is a opening to be rarely or very rarely played like I think I would never play it but one who want to play can play it 1/10

And why someone would want to play London system with white if there are many better option available and they are also 1000+ now it's time I think to say tata bye bye to London system I also played when I started chess

But now there are many more good openings available 

You can play e4, d4 queen gambit catalan, english, reti, ruy, Italian etc

"Have tried Caro Kann but that didn't work out"
++ Why not?
Caro-Kann 1 e4 c6 2 d4 d5 and Slav Defence 1 d4 d5 2 c4 c6 for black are most similar in ideas to London for white.

Yeah not same but the some pawn ateuctures are same

Maybe a6-Slav. Could as be boring as the London System :-)

A6 slav is a pupy slav -gowtham chess

I guess playing the Advance variation against the French, playing the Scotch Gambit line versus e5, playing the Rossolimo variation against the Sicilian... is not playing in system style?

The point is....London System, Accelerated or otherwise, is not refuted.  If it were, no titled player would ever play it.  Particularly in a prestigious tournament.  And especially against a GM.  

And no titled player (e.g., GothamChess - IM Levy Rozman) would create an instructional video recommending the opening, or write books on the opening, putting their reputations at risk.

Suggestion - be careful about making rash statements asserting that openings are refuted, simply parroting what you have heard from others.  An exception might be when more than one GM makes the same assertion.

Here we go again, with this stupid (for lack of a better word) argument that the London is "refuted". 

In case you don't understand English very well, "refuted" is typically referred to an opening that has been proven to be significantly worse/borderline lost, if not worse. As far as I know, that's not the London. 

As for the OP's question, I think the Caro and the Slav (against 1.e4 and 1.d4, respectively) are pretty solid options that emphasize the development of the LSB, which is typically the problem piece for Black.

^ This.

No means London is not bad or refuted but it has not much dynamics and is boring as you have to do the same thing against everything and this can effect our thinking power and reacting power to our opponents threats as it develops the habit of not seeing opponent moves in beginners which is very bad

Anyway it is opening which can be played ocassionaly in rapid and classical chess and frequently in bullet chess 

See, this is the kind of two sided stuff that happens here.

If a grandmaster does something, don’t automatically do it. You won’t understand the ideas and anyways, you aren’t a grandmaster, so you won’t play up to their standards even if you get out of the opening unscathed.

If a grandmaster doesn’t do something, you should follow in their footsteps! They obviously know better, and your opponents will all refute the London and equalize by move 10! London trash stop playing it. (obviously dramaticized but still)

OP, your opponents won’t know the theory to refute the London, and you’ll know the positions better than they will, so by all means, keep doing what you’re doing. As for black openings, the Scandi is relatively simple, easy to learn, and ALSO not common at GM level and is “refuted”, but totally fine.
