Besides, with all those movements before Kf7, white has time enough to prepare for castling on kingside.
Realy a joke opening ?

The Barnes defence is 1...f6, becoming the Fired Fox defence with 2...Kf7.
Named for T. W. Barnes, who used it to defeat Morphy in 1858.

But the advantage persists.
White is now one pawn up, in control of the center, developing pieces... not good for black player.
