Will it be Qd3 or Bg4 or Re1

Qd3 -> Go for Queen exchange

Bg4 -> Scare the Queen away and also good post for bishop

Re1 -> Control the E column, once pawns are exchanged.

Now, 18. b4 looks OK. Don't know if any chess engine would consider it here?

What say?

Rybka3_8cpu at ChessOK gives:

What are the other GMs thinking/saying in their commentary? White seems to be playing very good moves till now.
