This section deals with all variations after 5.Bxf7+ Ke7 6.Bc4.
The opinion of this variation is that it is a weaker option than 6.Bb3 and 6.Bd5 due to the fewer options and the exposed position. The lines are very similar to 6.Bb3 so I have not gone as deep in analysis. Overall, black seems to have an easier game.
B: 6…Qe8 7.0-0 (7.Nc3 Rf8 8.0-0 Kd8 9.d3 h6 10.Nf3 g5 and black has compensation; 7.d3 Rf8 8.0-0 Qg6 9.Nf3 d6 10.Nbd2 Bg4 11.Kh1 Qh5 and white has a small advantage) 7...
