The idea of playing the Jerome Gambit against a computer chess engine seems almost as irrational as the Jerome Gambit itself. How is it possible to give the silicon beast a couple of pieces and expect to survive? One doesn't give the computer "Jerome Gambit odds"!
Still, four years ago, I noted on this blog
It was not long after I began looking into the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) that I noticed one chess match kept turning up in the databases: in 1993, between the human Micah Fischer-Kirshner and the chess-playing program KnightStalker, an early version of Fritz. As luck would have it, I was able to interview Micah about his experience for this blog.
The Jerome Gambit seemed a natural for matches, especially ones involving computers. Jeroen_61 of the Netherlands ran one with Hiarcs, Junior 7, Shredder Paderdorn (6.02) and Fritz 7.
I tried a few myself, notably a Fritz8 vs Fritz5 encounter and a Delphi vs Wealk Delphi contest. Each attempt had its shortcomings. (Perhaps you read about them here.)
The mysterious "perfesser" played an introductory 4-game match with the Talking LCD Chess Gadget. Like the Jerome Gambit itself, it was good for some chuckles.
Topping all efforts so far, "RevvedUp" and his trusted companions Hiarcs 8, Shredder 8, Yace Paderborn, Crafty 19.19 and Fritz 8 explored the Jerome Gambit in a 30-game encounter. It was simply war.There is also the earlier summary of Randy Tipton's computer vs computer games, and the more recent adventures of "Ionman vs the Bots".
So, when I noticed that the new group of Bill Wall games had some of him playing the Jerome Gambit against some engines, I had to check them out.
The following game is very interesting. The human's flurry of tactics to finish off the game is impressive.

This is a small slip.
It must be noted that in a Jerome Gambit computer vs computer tournament over a decade ago, Hiarcs 9 chose 10...Kd8 three times:
