There are many, but openings are not that important to the beginner. All you need to know about opening phase is this:

How many openings are there?

1000-300-20-7?! Wow, had no idea. Thanks. I only have 1,327 more to master. Phew...

Thanks, I’ll check it out.

You're welcome. I hope you will find those helpful.
As a reference, I as a 1 500 intermediate player know just a few moves (3-7 let's say of the openings I play) and have an idea where should I move my pieces but not the order of moves of the openings I play.
So, as you can see, openings are not that important until we get much stronger. It's a tool for really god players to distinguish themselves. Some 40 centipawn advantage out of the opening is meaningless for someone weaker.
There are 20 at depth 1 ply, 400 at depth 2 ply up to rather a lot at depth 100 ply (50 moves). Some are better for White and some for Black and possibly some for neither side, but this is a bone of contention (see https://www.chess.com/forum/view/general/true-or-false-chess-is-a-draw-with-best-play-from-both-sides).

Thanks, I found the opening blog very helpful. I appreciate the insight!
Man! Just how many openings are there? i know I’m just a relative beginner, but every time i log into chess.com i read about another opening I’ve never heard of. Are they really that critical to a player at, say 1100ish? My current openings consist of “Jeeze-O-Pete!” “Holy Mackerel!” “Shoot I Just Got Stomped!” and my absolute fav, “Go Ahead and Beat The Living Daylights Outta Me Everybody Else Seems to Be Enjoying Wrecking My Game!” The last one takes longer to say than it does to be totally annihilated by, oh just about everyone. I’m starting to feel like Neville Longbottom.
