Best Black opening for beginners

Hi!  I've been mostly learning the London as a beginner to open games when playing White.  Is there an opening for Black that is best in terms of versatility no matte what opening White plays?  Is it King's Indian?  I need to develop a beginner strategy when playing Black.  Appreciate the help!

I don't know if there is an opening to that you can as black that is great to play no what white plays. Partially because white can open with a number of moves, and almost any of black's responses will have to be tailored to it at least a little bit.

Also at your  skill level learning specific openings is not the most useful. It is much more important that you learn the opening principles, and be able to apply them in every game consistently. That will help you no matter what opening you play or your opponent plays. You will also have play moves that are not a "book" move for the opening because most of the people you play right now won't know the opening, or how to play against it. Here are some articles for the openings: https://www.chess.com/article/view/the-principles-of-the-opening

Also two other things you should focus on: 

Tactics: This is the most important one right now because it will help you in all aspects of the game. It will help you prevent dropping pieces, and being able to spot opportunities to take pieces. Not just in the opening. This will also help you build your ability to calculate ahead also. The puzzles and puzzle rush on here are great to help you learn tactics. Here is an article that has the definitions of all tactics (although you only need to focus on the common ones for now, not all 38 of them (fork/double attack, pins, skewers, and discovery): https://www.chess.com/article/view/chess-tactics

Basic Endgames: What I mean by this is that you should know how to checkmate you opponent with two queens vs king, two rooks vs king, queen and rook vs king, king and queen vs king, and king and rook vs king. You should be able to do this even under time pressure. You may know some of these already, but this help you finish out won games.

Hope this helps

Very helpful, THANK YOU!

A low theory repertoire for black is: scandinavian defense against e4, semi slav against d4 (it's a colle system for black), and symmetrical english fischer variant against c4, for everything else use opening principles and common sense but also hippopotamus defense can work.

Of course tactics should be your main goal, but I think you can learn these openings in less than a hour. There is no need to go into details, your understanding doesn't have to be perfect just learn the systems and put them into action in your games and analyse them afterwards.

The best defence for beginners and world championship candidates alike is 1 e4 e5 and 1 d4 d5.
If you play the London as white then the Caro-Kann 1 e4 c6 2 d4 d5 and the Slav defence 1 d4 d5 2 c4 c6 have similar ideas: Bf5.
King's Indian Defence is very hard to play and has theoretical lines that run 20 moves deep.
You can play modern defence 1...g6, 2...Bg7 against everything as black, but then it makes sense to open 1 g3 2 Bg2 as white as well.

i have learnt the openings such as:caro kann,kings indian set up,petrov's defense stafford gambit,scandinavian defense,caro kann advance variation and scotch potter variation.

You probably get the most playable positions as a beginner by responding to e4 with e5, and d4 with d5. You stake a solid claim in the centre, and you don't have "problem pieces", like a bad bishop you'd have in the French defense for example. The resulting positions are also nice, in that they are fairly tactical but also teach you about positional ideas.

Thank you, all!

I use the French Defense as it is a very solid opening. Also, most e4 players at your level will be a little surprised against it as it isn't an open system.
