This blog has been very honest: the Jerome Gambit is a refuted opening. You can find the refutations among the 2,025 posts so far. There are Jerome Gambit wins and Jerome Gambit losses.
Do we really need another refutation?
Apparently the answer is "yes".

There are 213 games with this position in The Database. While 8...Qf6 here is routine, and 8...Qh5+ exotic, I looked at one response by Black, 8...Nc4, in the previous post.
Here comes a shocker.
8...Kc6!?
There are only 3 games with this line in The Database.
Can Black's King simply walk away from his Knight like that??
The remainder of the game suggests that he can.

13.Qb3+ Ka5 14.Bd2+
Worthy of a swindle was 14.Be3, as 14...Bxe3? would allow a draw by repetition starting with 15.Qa3+.
