I would download a car <| sep |> Maybe you address this in your video , couldn ' t hear it for technical reasons but 6 . Kf 1 seems to me to be pretty weak . You ruin your kingside castle and allow the Bishop to occupy a dangerous square on the board . If Black uses their Queen better than your opponent did , you can get into trouble real fast . I always play Nc 3 in response to the Bb 4 with ideas like Qb 3 to encourage the Bishop to trade . You are getting ready to go into an open game , so if you can trade off your weak knights for a two strong Bishop ' s attacking the Kingside , you will be in pretty good shape . In addition , you make your opponent weaker by taking his only active bishop off the board , and , icing on the cake , you still get to castle . Getting your king to safety is paramount , because the DG walks the edge with king safety . EDIT Also get ready for the Danish Gambit hate .
