There is a King's Indian Attack group, called "KIA inc.", for players of all strengths who are interested in learning that opening.

Other than that... for players around 1200 strength, I would suggest that most of your study-time should be spent on tactics, more tactics, model mates, endgames, and on analyzing your own games, especially the ones that you lost.
Opening study should focus on the typical Pawn formations that your chosen openings will lead to, and on the typical plans that these Pawn formations generate.
Welcome to my "thoughts" section about improving as a chess player.
First a bit about me, not played in thirty years = about 50 years old; never a good player, aiming for another 1,000 rating points above my 1200 rating i have now; LoL ;)
So i am a mature adult and i understand myself, my strengths and weaknesses very well. I am hoping by sharing these 'thoughts' with you it will help you improve as i improve toward my quest of "Master" ranking :)
THESE are only MY OWN opinions :
- We all love the beauty of great attacks, well i am not a huge risk taker and its far more important for a player to understand how to DEFEND firstly. This gives a player a grasp of how to see when to launch an attack and how to conduct it; so for at least twelve months i am going to focus upon a DEFENSIVE system.
- I will not use flank openings since i am to lowly rated to understand normal openings even so my openings will be as black the Scandanavian but always the Caro-Kann against White playing anything, even 1. d4 ( you can call it whatever; like Slav etc, but its MY Caro-Kann ).
- I will ignore learning any other openings except my own openings they are proven solid (played by Masters) and not totally fashionable at the moment, so over the next few years i should be able to get very good at them in my ratings quest to become a Chess Master.
- I will play some blitz games for fun and relaxation, some standard games just to learn how others play, but mainly i will play longer time limits so i have time to stop and think about moves etc.
- A word on 'Ratings' i do not care what my rating points are i will play stronger opponents up to 200 points above me and then analyse my games slowly and repeatedly; i will only play a few games for 'improvement' each week and then spend a lot of time dissecting them on a real board.
- I will mainly ignore the internet/computer i will study and read chess books i won and then re-read them and make paper written notes and diagrams. Computers stop me from 'thinking' whereas writing on paper and looking at a real board forces me to "focus" and reinforces my understanding.
- I am happy to lose if i learn something especially long term so my rating does not matter since i will learn something useful from each game anyways.
- I will do puzzle books on general chess readings for relaxation, i will read about strategy and positionals and i know i will not understand it but i will just try and get a feel for the ideas and be opening my mind to such thinking in preparation for the future.
- I will stick to my three/4 openings (as above) [Caro-Kann and Scandanavian] and as White the Veresov system / KIA (King's Indian Attack), i will vary these four openings to prevent boredom and to try and stay 'interested'.
- I am practicing "blindfold-chess" and imagining my openings and my opponents lines 'in my mind' without the clutter of the board. This way i can play chess in the shower or wherever.
- As my ratings improve i will add in two more openings in about a year or two, these openings will be 1. b3 and 1... b6 since they are not totally proven 'solid' but will be solid enough to a ratings level of 2200 if I myself become good enough at chess in general.
- i will devote no more than ten percent of my chess time to my openings since i must work on other things like strategy, my middle games and other areas of chess; more on these areas posted on HobbyDeck.com.
- I will not become 'obsessed' with chess nor talk nor read about it endlessly. I will balance it with work / family / recreation / fitness (chess is for my recreation and mental health).
- Everyone plays chess differently but ultimately for at least one of 3 reasons. 1) Enjoyment: (WC Tal played simply because he loved chess), 2) Reward: This is my motivation; not to become a professional player but to improve myself personally (the disipline and rigor of the game to make me a better person); this will help me at work as well, 3) Prestige: Masters do not spend thousands of Gold and sit at aeroplanes / hotels for days for fun. They do it to contest against other very talented people...
Anyways this is my "recipe" toward becoming a chess Master [and who cares if i do not reach it ? ] i will have a solid good cheap hobby for life and get many benefits from the world of chess. Now i have my "recipe" all i have to do is 'cook' it :) plus i am doing all this solo, no personal trainer nor major computer assistance, just books of games / ideas / puzzles / 'REAL' chess boards and lots of balanced 'hard effort'.
I only place this here so other beginners might come to love playing chess as i hope i might come to 'love chess' and might find ideas in my "recipe" for their own improvement.
ABOVE ALL, do not chop and change your openings nor follow the pack and play things you do not feel comfortable with. You SHOULD be playing for YOURSELF so do not let others 'tell' you you must change, get a 2nd and 3rd opinion (from 'different' sources)...
BUT above all have a plan for your study/ improvement, work out your goals and write them down and why you feel they are important to you at that stage of your chess / life...
