Anderssen Opening is actually genius?

Is this opening genius? If the opening turns into a Sicilian open white will have an extra tempo in the Najdorf:

If the opponent doesn't decide to go into the Sicilian open then white will just be ready to attack the queenside. 

Black has already gained the advantage in space, and development.

Black doesn't have to play these moves though

Black hasn't gained any development, its just like white is playing black with a3 already made.

After the last move in your diagram. 

Who has more pieces developed?

Whos center pawn is farther advanced?

I'm not saying this isn't playable.  Im just saying that your "extra tempo" as white isnt there. 

Taking this step by step. 

Anderssen's Opening is an anti-system for the King's pawn game.  All of the 1. e4 openings depend to some extent on the ability to place a minor piece on b5.  So, if you play 1. a3, and black responds with e5 (playing king's pawn with the colors reversed), white can play "as black" through any and all book lines with advantage.

Paul Morphy played 1. e4 without fail, and this was who Anderssen was playing when he rolled out 1. a3, and it worked better than anything else he tried (though he only scored 50% with it).

I should note that 1. a3 is also useful against the English and the Reti with colors reversed (1. ..c5 and 1. ..Nf6, respectively), as the pawn on c5 can be quickly challenged by the developing move 2. b4.

Of course, this seems to imply that the best reply to 1. a3 is 1. ..d5, because the a3 advance is not terribly useful in many of the Queen's pawn lines.  That's what I play, anyway, when 1. a3 is played against me.

A thoughtful reply.  Thanks.

Stop using your cringy reaction gifs

Tell me what the difference between this:

And this is:

The lines to consider when looking at reversed openings are not the very sharp ones where an extra move like a2-a3 might come in handy, but the very simple ones which no one plays as White because they're just completely equal. In the reversed versions of these, the extra move is usually meaningless, and Black can be perfectly satisfied with being equal.

- For some other reason, Black complied, and allowed this.

allowed ?....well then which move would NOT allow this ? s/he hypermoderned right ?

- In the end, white got what he wanted: Easy equality as white! Or maybe it is not THAT easy, after all?

isnt it black that wants equality here ?...as white has it by default, right ? i mean isnt that the whole point of getting to move first ?

(are u sure its not u who's logic has collapsed ?)

ykw ?...why donchu go back to the Karpov vs Miles game (1. e4 a6). thats a good ex. of BLACK giving up equality. but then alotta good it did K.

play 1...-a6 and watch em struggle :cool

Because it's white to move!!

At the OP's level 1.a3 is perfectly playable.

We really don't need your profile pic to figure out you support trump. a3 is a perfectly playable move in any level of play!

My political affiliation has nothing to do with your subject. 

I wonder why we dont see Carlsen ,or other GM's playing 1.a3 in OTB tournament play?

You should get together with that Lyudmil guy, staples, and all the other "online players" that have solved chess.  You guys could revolutionize the game, and make a fortune!
