Title: 2. e5 in the Robatsch (Modern) Defence
ThreadText: # 2. e5 in the Robatsch (Modern) Defence
  
  (Asked by: username_0 on 2015-09-21)
  
  Since the modern defence is a hypermodern opening, it focuses on controlling the center through pieces not pawns. Therefore, I find it an advantage to block these pieces by pawns. So, I defend against the modern defence like this ..
  
  ```
  [fen ""]
  1. e4 g6 2. e5
  
  ```
  
  The idea is to block the bishop that is coming to g7 with 2...Bg7, and to prevent the knight from going to f6 and thus prevents castling kingside.
  
  Now, if Black tries to attack the pawn, this happens ..
  
  ```
  [fen ""]
  1. e4 g6 2. e5 f6 3. d4 fxe5 4. dxe5 d6 5. Nf3
  
  ```
  
  If Black takes the pawn, then white is clearly ahead in development. If he doesn't, then he can't deploy his pieces effectively.
  
  Anything wrong with this plan ?
