Ofcourse it threatens axb but what it the real value of this move after black defends with Bb7 or something else?


I think you are on the right track with your thinking.  I always thought one of the main ideas behind a4 was not so much space or pawn chains but to more or less "force" Black to develop his bishop to b7 instead of giving him the option of ...Bg4.  I think you will notice that the timing of a4 is very often after Black plays ...d6.

Of course the other positional characteristics cannot be ignored.

I would believe that the advance a4 in the Spanish has been commented many times in chess writing. One source is Mastering the Spanish by King and Ponzetto. For example on page 31, they write that there is a double aim with this advance when the center has been closed with d5. "Exerting strong pressure on the b5 pawn and putting himself in the position of being able to open up the a-file. I recommend this book if you want to understand Spanish structures.   


Yeah, but of course, it's not only Spanish positions, but it's just chess in general that if your opponent has some sort of pawn chain set up with its head on b5 or g5, you often play a4 or h4 to loosen things up, either to win a pawn, make inroads with your pieces, or open the a- or h-file.  One thing that makes the Closed Spanish so awesome for White is that due to Black's having weakened his queenside like this, White has options to play there, not only in the center or on the kingside.  It wasn't for no reason that Lasker and Steinitz and people of that era avoided moving their pawns.

a4 idea in Ruy Lopez

In the following game http://www.chessgames.com/perl/chessgame?gid=1044287 Fischer playes 11.a4 this move seems standard in many the ruy lopez variations. Ofcourse it threatens axb but what it the real value of this move after black defends with Bb7 or something else? Is it just a move to gain space or is it more deep then that. Also when should you consider playing it? I have very little understanding of why this move is played and therefore I'd be happy for some beginner explanations for some talented people. Thanks!
