It's called the "High School Variation" for a reason.  

yes, but black just did this bad move.

I think it's important sometimes to take a step back sometimes and observe some facts...: 

1) The idea of chess being mainly about opening preparation and one strategically bad move being a disaster that can never be recovered from mainly only applies for long games with FIDE masters and better.  

2) The opening isn't so bad, white just gives away most of the initiative. There are no fireworks. Black shouldn't expect a great attack, but he can probably expect to win as much times as white does if white plays this way. Even Super GMs vs Super GMs would likely not expect to win as black against this opening, but they would likely draw with equal skill.     

yes, but Bc4 is not toooo bad.

yes, your right. Almost every game is like that. the players are used to it. also, I play like that!      P.S. My rating is 1470                                                                                                                                               

It's common at all time controls. They're usually 1...e5 players themselves who wish you'd played 1...e5 against them and they wish it so bad they decide to pretend that's what happened and try to play an Italian Game against you anyway. What's worse is if you play a d6 Sicilian, if they go 2.Nf3 d6 then Bc4 the plan with e6-d5 has lost a tempo.

Against the immediate 2.Bc4 I prefer now 2...Nc6 first before e6, because I'd prefer to develop a piece rather than make a pawn move there, also they're more used to seeing 2...e6 so 2...Nc6 perhaps makes them feel a tad uneasy, e6 will be played soon enough. After 2....Nc6 White should bring out one of their knights to which Black should play 3...Nf6. After this e6 usually follows. Against an e5 push d5 is usually the answer.

In many variations after e6-d5 the e-file opens and the pawn structure is similar to the French Exchange. After e6-d5 if the bishop goes to b5 pinning the knight a policy decision must be made whether you want to allow the doubling of your c-pawns in exchange for the bishop pair or if you'll play Bd7 or something. Practically lI think Bd7 may be the better thing to do.

Also sometimes they'll play a quick a3 or a4 to tuck the bishop back on a2. In these variations I've sometimes been able to trap the bishop there, even once entering a light square vs light square bishop ending where their bishop was on a2 with a black pawn chain a6-b5-c4 and my bishop controlled the h7-b1 diagonal so there was no way for them to get it out. It's kind of hard to achieve this but when you're able to it's absolutely great.

The White player usually tries to be aggressive and shunt all their pieces over to the kingside. I think for this reason making the e6-d5 break early is a good thing to do, after an exchange on d5 with the e-file opening all the heavy pieces tend to get exchanged and the game becomes like a French Exchange but my king seems to come under less pressure there.

Hey man, I don't know what age you are or intelligence level you have but don't EVER copy someone else's post and pass it off as your own. NEVER do that, it's a horrendous thing to do. You copy and pasted this post https://www.chess.com/forum/view/chess-openings/sicilian-2bc42 , don't do that again. Your stupid [Edited for language - Mod.] idea of just posting games is nonsense as well, get a life. 

It may be common at all time controls but it's not common at all levels. The higher the level you go the less likely you are to see it.  e6  followed by d5 when possible and as Sco64 says it's a loss of tempo. White has some tactical shots as you say.... trying to make the white bishop active by switching diagonals, trying to open up the file and create complications.... and it's easy to make a mistake, but in the end when played accurately the tactics do not work and white is a tempo down compared to other openings. It's not as clear-cut as the loss in tempo against the Caro-Kan, but if white's light-squared bishop becomes well-developed in this opening without developing other weaknesses then black has failed.   

How was this post copied? I will agree, in a not-so-aggressive tone though, that just posting games doesn't make much sense. You didn't ask a question or even make a statement. So I don't know what you're looking for. Are you looking for advice on how to play it successfully? Are you asking if people think it's a good line? Are you bragging about games that you won while playing it?

Your 1st game black played pretty badly, imo. While you may get away some times by playing it now, when you start losing because of it, I guess you'll understand more. The 1st game for example, Black playing a5 wasn't good, better was a6, with the threat of b5, trapping said bishop,after you moved knight to b3. Also him moving his knight to d7, was bad. He could have moved his bishop to f5, after you moved f4, a much better move. His knight was fine on f6. 

If you look at the link it was a copy and paste of an earlier post. I thought it was odd that someone who just came and posted a few games without comment would suddenly come up with all that so I searched for a sample of the writing and as in the link I posted it's a copy and paste from a post that was made before.  

Oh, I see the copy and pasted comments now. That's really weird. I don't get why anyone would do that.
