Scotch Gambit, Max Lange Attack Accepted

This branch of the Max Lange Attack has White answer 8...Be6 with 9. fxg7, collecting a kingside pawn instead of playing the main line 9. Ng5. Material is level. Black's kingside is broken into isolated f- and h-pawns, and Black's c-pawns are doubled, though the advanced pawns on c4 and d4 cramp White. White's g-pawns are also doubled. Black almost always replies 9...Rg8, attacking the g7-pawn along the half-open file. Engines consider the position roughly balanced, while White scores well in practice.
