And d5 against e4 is equally effective
sicilian for beginners
Hey when i play e4 noone and i mean noone has ever played c5 against me
I know the feeling. I know the tally...I've seen the databases...I hear the constant fretting about all the Sicilians we're supposed to be facing. And fact is, I LOVE playing the open Sicilian as white. I think they're the most interesting and exciting lines in all of chess.
But over the course of my chess life, spanning thousands and thousands of games, I've faced EASILY ten times as many 1...e5 replies as Sicilians. And I hate the open games.
I've just come to assume the universe has it out for me.

As both a beginner and a sicilian player, I say try it out and if you like it stick with it. Everyone says there is sooooo much theory but as a beginner do you think your opponents know the theory as well? After the first 5 or 6 moves we are just winging it anyways. I like the tactics that come from it but at my level I'm not worried about my opponent knowing all the theory.
My OTB rating is 2100 not my 1500 online rating just so you see there is merit behind what I'm saying. I would not play the Sicilian because of sidelines. I remember when I lost in 17 moves against the Smith Morra Gambit. 2.d4. And when I lost in 20 moves against the Grand Prix Attack. 2.f4. I would have to recomend something more solid like the Caro-Kan or the interesting Scandinavian. As a newcomer to the game, I have to recommend you play a solid opening thats easy to learn and work on your endgame skills. In my opinion, it's the most important part of the game. If you work hard, you will find yourself saving and maybe even winning lost positions as well as converting the full point fro a minimal advantage.

For beginners, I don't think there's any reason to avoid 1.e4 e5
It shows you the complexity of openings, if nothing else. I mean, why is it SUCH a big deal what move black plays after 1.e4 e5 2.Nf3 Nc6 3.Bc4 --- hey you can play Be7, Nf6, Bc5, h6, d6, right? They're all the same!
For intermediate players... well when I was an intermediate player I took up the Caro-Kann. I did this, because it REALLY gets people out of their comfort zone at that level. It's really frustrating to play into other people's preparation, and so I chose to avoid all of that. And I didn't want to play the French because at those levels a lot of people play the exchange.
For advanced players, play what suits your style. You can tackle this by first finding a Grandmaster who has a similar style, and then copying their opening repertoire.
I do not agree with that. I think the key should how will I get edge over my opponent in the opening. Since as a beginner, I do not know much about openings, it is wiser for me to go a line where less opening theory is there.
For example, bird's opening f4 is very effective as white
