One question – after the knight moves to take up Nf5, what would you do if Black held back on playing Nf5? Bd3 does look look too good at this point because of c4. For instance, in your game. If Black played Be7 and held back on Nf5 for another move, would h3 be a sensible waiting move – prepares the king escape square before castling. I notice some players have opted to play d4 at this stage.
