Knowing your chess opening and what you and others have played previously is a powerful weapon in a contest.
Bill Wall's games show up over 365 times in The Database; he has a lot of experience with the Jerome Gambit - usually a whole lot more than his opponents. (As a reference, The Database's over 51,500 games is useful, too.)
It is no wonder that the following game ends quickly.
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Kf6
MrJoker and I have explored 8.d4: perrypawnpusher - whitepandora, blitz, FICS, 2008 (1-0, 41); mrjoker - Taj, Internet Chess Club 2009 (1-0, 9); perrypawnpusher - tjaksi, blitz, FICS, 2013 (1-0, 16); and perrypawnpusher - alvarzr, blitz, FICS, 2014 (1-0, 21).
Not 8...Qe7 9.Qf5# perrypawnpusher - zsilber, blitz, FICS, 2010.
As opposed to the retreat 9.Qe3 seen in perrypawnpusher - useche, blitz, FICS, 2010 (1-0, 22); perrypawnpusher - wbrandl, blitz, FICS, 2011 (0-1, 28); MrJoker - ipon, Internet Chess Club, 2011 (1-0, 33); and MrJoker - vicwill, Internet Chess Club 2011 (1-0, 12).
Now Bill is on his own, as there are no other examples of this move in The Database; but his opponent immediately helps him out.
9...Ne5 10.f4 Black resigned
