can someone show me where you move next??

6.d3 kicking the knight out is the BOOK move.

d3 or mabey  nc3

yeah i usually do move to d3. but then knight moves back to f6, so then i take queen... idk cuz then black has an advantage of castling

Well, you could decide not to take the queen, giving black a chance to take your queen and thus you can castle.

you dont have to be the person who initiates the exchange of queens.

hmm.. i see. so i develop pieces. and what if black does the same? then we just sit with our queens pinned? lol

6d3 Nf6 7.Bg5 white hopes to make something of the tempo or two lead. Players like Spassky, and Lasker have used it, but it's not the most exciting line.
