Jerome Gambit: Reader Contribution?

 

Yesterday's post was a small attempt to address April 1 - April Fool's Day.

A clue was the "reader's" name, Avril Furst.

The position was actually from the game Jerome - Amateur, offhand game, Illinois, 1876.

By the way, the game could not have ended with 20...e5 21.fxe5 e.p. checkmate, as the game had started as a Jerome Gambit, thus, the first moves 1.e4 e5. The e5 pawn disappeared with 5.Nxe5+.
