This is the typical response in the modern defence against the classical development of W with both center pawns and both knights. I confess, I don't often end up in this position, so I'm not sure I fully understand it, other than that it aims to push the B pawn forward to B5. I take it this has two important results if I get the pawn to B5. One is that W's light bishop is becoming stifled, and another is that I'm developing a pawn chain that's putting indirect pressure on the center, and I'm also further opening up my queenside to develop pieces.
