What follows is the first training game from Sacrifice Theory. The Bishop mentioned in the previous post (see "Jerome Gambit: Sacrifice Theory").
The Jerome Gambiteer punishes his opponent's King when it recklessly advances into danger.
Training Game #1
2024
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6
7.f4
Instead, "Jerome Gambit: Analysis Leads the Way (Part 1)" looked at 7.Qh3+ directly
This is the strong move Yury analyzed in the posts given above ["JG: The New (Part 2)" and "JG: The New in Its Opening Theory, in Its Psychology (Part 8)"] and in the majority of other posts of this his series having Parts 1-9 now. [Currently Parts 1 - 17 - Rick]
I do not know if he realized that he was improving on play by Alonzo Wheeler Jerome, himself, from an earlier correspondence game. The "Games" column of the October 1881 issue of Brentano's Chess Monthly had a submission by S.A. Charles,
..Some time since, I published in the Pittsburg Telegraph a compilation of such analyses of the Jerome Gambit as I could find, with some additions from published games. Mr. Jerome justly criticized some of the moves as not being the best for either party, and we commenced as series of correspondence games more as a test of the opening than of individual skill. Unfortunately Mr. Jerome's business engagements have prevented him from playing out the full number of games originally started; yet the situation even in the unfinished games seems to me at least to prove the gambit unsound, and that while White may win against weak, he cannot do against strong play.
Jerome, Alonzo W - Charles, S.A., correspondence, 1881, was an early example of what was to be called the "annoying" defense: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 d6, which Jerome decided to meet with 8.Qh3+. After 8...Ke7 the game continued for only 5 more moves, but it is clear that White had less than nothing.
By playing his Queen check a move earlier, Yury gets to play, among other things, against the unprotected enemy Bishop at c5.
First seen in two games between The Perfesser and Talking LCD Chess by Excaliber [(1-0, 20) & (1-0, 23)] in "Jerome Gambit and The Perfesser (Parts III & IV)".
Of course, 8...dxe5 was for choice.
9.Qh3+
9...Kxe5
More prudent was attending to the King's safety with 9...Kf7.
10.Qg3+
White would have to have nerves of steel to enter the sacrificial line 10.d4+ Bxd4 11.Bf4+!? Kxf4 12.Qg3+ Kxe4 when 13.c4 Kf5 14.Rf1+ Ke6 15.Qg4+ Ke7 16.Qxd4 Nf6 17.Rxf6 Rf8 18.Rxf8 Qxf8 would be about even.
10...Kxe4
Advancing too far, eating too much. His only chance was 10...Ke6.
11.Nc3+ Kf5 12.d4 Qe8+ 13.Be3 g5
14.O-O+ Kg6 15.Qxg5 checkmate
For the record: 14...Ke6 15.Qg4+ Ke7 16.Bxg5+ Nf6 17.Bxf6+ Kf7 18.Qg7+ Ke6 19.Rae1#
