so i've been playing chess for a long time, i just never really knew there were names for different openings. Well in order to set up my game i've been reading about openings, but there is one thing that confuses me. That is when i'm looking at an opening how do i know if its for black or for white? and if an opening is for white, can it be used for black? i know this question might be a beginner question, but like i said no one ever taught me openings or names, just how to play.

thanks for the replies.

James
