As I've never played this opening, I wouldn't know off hand. The way I see it, you can do a number of moves.
1) Bg5, with the intention to trade off and make the position less symetrical and mroe interesting.
2) Be2, with the intention to castle and develop more pieces.
3) b3 or g3, with the intetion of Fianchettoing the bishops.
4) Nd5, to begin gaining the initiative and gaining space.
Hope this helps, though it probably doesn't.
Currently, I enjoy playing the English Opening: Queen's Knight Variation (1. c4 e5 2. Nc3). However, this will sometimes fall into a symmetrical position (shown below) that I DESPISE playing in. Any suggestions? Thanks!
