Jerome Gambit: Leads to A Highly Complex Position

 

In 900 Miniatures of the Blackmar-Diemer Gambit, Eduardo Piza writes

When discussing the merits of a particular move, it is important to consider not only its immediate impact but also its long-term consequences. A move that may appear to be a poor decision at the time may, in fact, be a strategic error that leads to a highly complex position where it is likely that one of the players (or both) will end up making a mistake. This is precisely what occurs when a gambit is proposed. A move that is not entirely accurate is deliberately made, which introduces an inequality into the position, creating a high degree of difficulty and making it unlikely that the opponent will find the optimal defense

Piza has in mind the Blackmar-Diemer Gambit, 1.d4 d5 2.e4 dxd4 3.Nc3 Nf6 4.f3, but he might just as well have been talking about the Jerome Gambit,  1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.
