The Return of Jerome Gambit for Dummies (Part 5)

Continuing my search for the "essence" of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), or at least an insight into how it "works", I discovered that 7-move wins by Black were not so much improvements in defense (after all, after accepting two sacrificed pieces Black needs merely to "hold on") as they were instances of White throwing away a Knight (see "The Return of Jerome Gambit for Dummies Part 2") , a Queen, or a King. Some examples of the last case are given as a warning for White to "pay attention".
