The best way to study openings is by trying to memorize all the moves (all main lines and sidelines of each opening). You should start in alphabetical order: first learn Alapin then Alekhine defense etc., the trick is to really learn them well by heart. You'll improve your ratings in no time and if you don't you'll at least enjoy trying...good luck!
How To Not Study Openings?

Capablanka did not ...
Snake, that's a pretty poor attemptat humor.
Fog, there is a way to play openings by good technique. At your level, the most important things are fundamentals: Develop all your pieces ASAP. Castle early. Make sure you have central control (one rule of thumb is to have at least one Pawn in the center; it's not absolutely necessary, but it is safer than not having a P in the center in most cases). Don't grab a stray Pawn in the first 10 moves if it means your development or King safety is severely compsomised.
Every time your opponent moves, ask youself, "What does that threaten? What squares is he controlling now that he couldn't before? What squares did he give up control over by making that move? Does that move stop me from doing what I want to do? (Which means your moves should always be aiming toward some positive goal, of course!)
At all levels of chess, games are won and lost by tactical oversights. The lower you go on the rating scale, the simpler the tactics become. In the opning, middlegame or endgame, always look for tactics. Look for undefended (or under-defended) pieces. Look at all checks. Look for enemy pieces that are a Knight's move apart (or that can be baited into being a Knight's move apart [forks]). Look for pieces on the same rank, file, or diagonal (pins and skewers).
I hope I am not overwhelming you! Chess is hard, but if you concentrate and look for your opportunities, you can succeed!
There are over a dozen of opening theories out there to even think of studying each one. Is there a way to play the correct openings just by good technique or any chess sense?
