Sometimes, if you act resolutely, you can look like you know what you are doing - even if you don't. In the following game Black makes decisive moves, like he is in the process of refuting White's silly little gambit. Indeed, the game lasts only 13 moves - but it is the Jerome Gambit that triumps.
Wall, Bill - Tedah
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Ke8
We last saw this adventurous line in the latest "Cliff Hardy" adventure, gfdgfd - leleos, InstantChess.com, 2016 (1-0, 17).
6...bxc6? 7.Qh5+ g6 8.Qxc5 Ne7 9.Qc3 Black resigned, Wall,B - Qwerty, Chess.com, 2010
Black's response is reasonable, although his best response might be the highly unreasonable 6..Qh4!?
Or 7...Kf8 8.Qxc5+ Qd6 9.Qe3 Nf6 10.e5 Ng4 11.Qf4+ Black resigned, Wall,B - Gebba, Chess.com, 2010.
8.Qxc5 Qe7 9.Qc3 Qxe4+
Black has returned the gambit piece and is able to get his Queen into the attacking action. If White now flinches at this aggression toward his King, say with the protective 10.Qe3, then Black can develop with 10...Nf6 and have hopes of reaching a drawn Bishops-of-opposite-colors endgame...
But things are more complicated than that.
10.Kf1 Be6 11.Qxh8 Bd5 12.f3 Bc4+ 13.d3 Black resigned
(I have to admit that I have no idea what Black's last handful of moves was about.)
