Answers.Body: <p>I am not a chess master so take this with a grain of salt.

  <p>I think that playing those moves or preparing a queenside expansion pretty much depends on the position, but in this particular position I would not consider doing this (a3 b4) at least for now.
  Note also that in some position a3 (not necessarily followed by b4) might be convenient to avoid the jump of the Black knight to b4, however, now (with the absence of Black bishop from f5) that does not look particularly dangerous.</p>

Body: <p>I'm playing recently the English opening. specifically this line in the two knights variations</p>
  
  <pre><code>[FEN ""]
  1.c4 e5 2.Nc3 Nf6 3.g3 Nc6 4.Bg2 
  </code></pre>
  
  <p>But I find it difficult to see when it's advantageous to go queen side with <code>a3 b4</code> idea rather then play in the center with <code>e3</code> maybe <code>d4</code> later on.</p>
  
  <p>Any thoughts ?</p>

  I'm playing recently the English opening. specifically this line in the two knights variations
  [FEN ""]
  1.c4 e5 2.Nc3 Nf6 3.g3 Nc6 4.Bg2 
  
  But I find it difficult to see when it's advantageous to go queen side with a3 b4 idea rather then play in the center with e3 maybe d4 later on.
  Any thoughts ?
