the Sicilian. why does no-one on this site play the main line as white?

as black when i see e4 i play the Sicilian. but no-one on the planet plays normally against it. they don't play different variations like the 3. Bb5+ line which i don't mind playing against. it's when people do things like. 2.d3. why? no reason i never see this variation when i revise the Sicilian. there are some other odd ones I've had to play against but not once (unless I've forgotten a game) have i seen the main line which is.

instead of what should be played i get something like this.

is it because people have no idea what the Sicilian is so they just act spontaneously. surely they must know it because it's the most popular defence played among masters and most chess players would watch master games so wouldn't they know the main lines?

so my question is: why do people play odd things against the Sicilian when the main line is solid?  

 

No one on this site plays it? You have already played against all of them? 

what's your point i mean when I play the Sicilian no-one does the main line against me.

i think you may of mis-understood what i meant.  

the first ones whats supposed to be played. the second one is what people who play as white against the Sicilian when they haven't revised it.  

I don't know what answer you expect actually. 

I play sidelines like 3.Bb5 because in the main open Sicilian black gets to choose his favorite setup, and as white I have to know about each.

People play 3.d3 against you though because they don't know what they're doing, and are just making random moves.

i don't mind people playing a side line. i'm just shocked that people play random moves against the Sicilian because they don't know what they're doing. everyone must know a bit about the Sicilian it's really famous.  

why don't they know it? when they watch master games on YouTube or something like that they must see it because it's the most played reply to 1.e4 so when they see it they should think 'i don't know this opening i should revise it.' 

Be careful about underestimating these seemingly random moves.  GM Simon Williams recently showed a very interesting Sicilian set-up based on 2.Be2.  Yes, seriously, and then following up with d3 ... and a mating attacking 20 moves later.  Great fun.  Game starts 7min in.

Anyway, over my chess career, I've had better historical success as White by avoiding the mainlines, be it 3.Bb5 or 2.b3 or the Prins or whatever, then the mainline Open Sicilians, and similarly with Black, I have much better results against 2.Nf3 and 3.d4 then all these other sidelines, innocuous or not.  I tend to think that at the amateur level, especially the beginner amateur level, avoiding the Open Sicilian is the best practical choice for White.

in the game i referenced i was never being majorly attacked and especially no mating attacks. the opponent i played didn't know anything about the Sicilian. i've played no-one on this site who knew a lot about the Sicilian. your overestimating the skill of the people i'm playing.

thanks for the suggestion anyway. 

After the moves 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 you are not seeing the forest for the trees.  If you will look at the pawn structure you will see that Black already enjoys a  2 vs. 1 pawn majority in the center.  Black pawns at (squares d6 and e7) White pawn at (square e4).  This ia an advantage that in  no other opening Black achieves so early in the game.  The 2 vs. 1 central pawn majority is an advantage for  Black throughout the  game.  Especially in the endgame.

The only drawback is the Achilles Heel in tactical terms with the pawn  at e6 that White can exploit..  However, it is a trap that Black can avoid.

Primarily  because of the  2  vs, 1 pawn majority in the  center White opts for anti-Sicilians like 1.e4 c5 2.Nf3 d6 3.c3 (delayed Alapin variation)

It's frustrating to get no practice in the lines you know.

As for well known openings, I'll still see lower rated players copy the losing side of maybe the most famous game ever, Morphy's opera house game, with 1.e4 e5 2.Nf3 d6 3.d4 Bg4?!

Well, sort of. The 2 center pawns are annoying mostly because there are so many options. e7, e6, e5, d6, d5 in one combination or another. White has space and development. Normally black would be unquestionably worse, but by staying on the 3rd rank and having no major weaknesses black eventually catches up.

From what have I experienced while playing in OTB tournaments, unless your opponent has a high rating, most people don't have that great knowledge of theory. So if you have spare time, you can generally outbook them in the main lines and get a positional plus right out of the opening. Importantly, most variations of the Sicilians, at least the mainlines, cannot be played on general principles. And generally it's easier to find moves to find moves OTB for White then it is for Black. 

i'm asking in a very long way why people (around my rating) don't know the Sicilian. what's stupid about that.  

White can get away with 2 or 3 BS moves in the opening (at which point they're basically playing as if they were black).
