The Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can affect defenders differently. Some will think "Somehow I never learned about this crushing attack, I am doomed" while others will think "I now have a won game that will play itself". Both mind sets can lead to disaster over-the-board, and another thought, that there are other games to play...

9...Ba6 10.d3 Nf6 11.Qb3 d5
Often a good move for Black, it is not well-timed here, as he has overlooked something.
12.Qa4+ Black resigned
Clearly, Black was discouraged after his slip. The game could have continued 12...Qd7 13.Qxa6 dxe4 14.0-0 exd3 15.Rd1 Qe6 16.Qxd3 Kf7, when Black would have simply been down a pawn.
The Jerome Gambit has a way of making opponents think that moving on to the next game might be a good idea...
