While most modern chess masters, justifiably, have nothing to do with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), years ago International Master Gary Lane had a bemused affection for the offbeat opening, and discussed it in his "Opening Lanes" column at ChessCafe.com, and in his book The Greatest Ever Chess Tricks and Traps (Everyman Chess, 2008).
Lane's book is still available, but his two "Opening Lanes" columns - "A Game of Shadows" and "Trash or Treasure?" with Jerome Gambit content are no longer freely accessible in they way they used to be (i.e. direct link via ChessCafe.com), which means that the links supplied previously by this blog (e.g. in "International Master Gary Lane" and "Opening Lanes") no longer work.
ChessCafe is currently maintained by ChessEdu.org, which requires a $25 (or more) "tax deductible donation" in order to access their "thousands of PDFs and hundreds of Ebooks" (including "Opening Lanes") available to members.
However, through the wizardry of the archiving Wayback Machine website, you can still feast (gratis) upon IM Lane's Jerome Gambit creativity: "A Game of Shadows" and "Trash or Treasure?". (These links have also been updated in the Wikipedia article on "Giuoco Piano, Jerome Gambit".)
