I know the moves in this example aren't great, for example Black moving the bishop twice, but it just serves as an example of a type of scenario that keeps coming up in my games.

And I really don't want to play d4 because I don't like that pawn formation.  (Or is White's d4 a normal part of the Reverse Leningrad variation of the Bird's?)

  <p>I know an e4 push for White is thematic in this opening.  But I often run into situations like this where I don't get a chance for that push, I'm more worried about things like Black's knight going to g4 and joining forces with the Bc5.
