It is very common for a chessplayer to look at White's first few moves in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and ask himself, "What is White thinking??" Sometimes the first player has a head full of fever dreams like the following games, which I turned up while looking through The Database for 8-move contests containing the "essence" of the Jerome Gambit, or at least an insight into how it "works".

Yes, indeed, things frequently go differently, if Black defends properly; but these games reinforce the lesson Tartakower liked to pronounce about some opening ideas, that is "dubious, therefore playable". Black relaxed and told himself that he would get around to defending, any time now – to his misfortune.
