I stopped playing chess alot for a while but still have always really sucked at doing openings while playing black, any suggestions on some to study up on?

openings are over rated. play good chess and worry about the  opening when your facing expertsand masters on a regular basis.

Scott is right. Although, it does help to at least be familiar with an opening -- it doesn't have to lead to an early advantage for white or anything -- you just want to be familiar with its strategies and typical tactics.

Consider annotated game books (that are instructional as opposed to just the showcase variety of books). They usually provide an excellent place to "shop" for openings and contain a ton of chess lessons buried inside each game! 

I recall falling in love with the Queen's Gambit Declined (for Black) and learned so much about the ideas for black in this opening by reading through just a few games.

Golden examples of these books would be titles like Chernev's Logical Chess, Chernev's Most Instructional Games, Euwe's Chess Master vs. Chess Amateur and the more recent Understanding Chess Move by Move by Nunn.

For black you should have one opening against 1.d4 and one opening against 1.e4.
Or you could play 1...g6 against any White Opening which is what Lloyd Kawamura 2350-2400+ plays.

Usually against 1...g6 I play 1.d4 g6 2.h4 pawn thrust and try to get the pawn to
the h6 square to disrupt blacks development. If black plays h5 to stop the pawn
thrust then the f7 and g6 pawns become weak. They become targets for my
kingside attack. Last week I played 1.g4 which surprised him because he did
not play 1...g6 and went on to win that 5 minute blitz game. Also he did not
know the lines in the Grobs Attack 1.g4.

agree with all except the one against d4 one against e4

try to have three or four responces to whites most common first moves (e4 d4 c4)

and be versed in all of them, only know like one line of theory deep, and the rest know two or three moves in. You will slowly build up a database in your mind as you play games, which is a good thing, because you can recall your prievious games and use knowledge gained from them to defeat your opponent

scott can you alaborate on good chess? simply opening theory, making moves with the moves of yourself and oppenant ahead in mind? how many moves? not trying to take away from your post, i myself am not a solid chess player and am looking to imrpove, i look at endless tutorials on opening but am looking for a way to improve at the current level where random moves are played constantly.  Also does it not help to know certain gambits at least so that you avoid them? thanks guys

ps sorry about spelling, ive been useing word correct for far too long now

knowing gambits is important, they build tactical knowledge, and iprove ones game immensly.  ie the KG.  Great opening where white has many options

the long sideline is the famous imortal game.  you should also look at the evans gambit and the queens gambit
