Long Lost Cousin?!

Much like the long lost cousin who you wish had stayed lost, the Knight sacrifice in the Exchange Variation of the Ruy Lopez bears a family resemblance to the Jerome Gambit.

Ruy Lopez Jerome Gambit

Still, as suggested in the notes to Pigjuice - perrypawnpusher, blitz, FICS, 2011, 6...Qxe4+ was stronger than the move played and reduces the resemblance. The following ICCF game, where a 2200+ player is schooled by someone rated over 450 points lower, puts things in perspective.

Christiaens,R (2242) - Dumont,G (1777)
Tournoi Accession 009, ICCF, 2009

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6

The good old Ruy Lopez, Exchange Variation.

Black's coming pawn grab and Knight sacrifice are not considered part of his best defense.

5.Nxe5 Qd4 6.Nxf7

Recommended by Rybka is 6.Nf3 Qxe4+ 7.Qe2 Qxe2+ 8.Kxe2 Be6 9.Re1 0-0-0 10.d3 h6 11.Kf1 Nf6 12.h3 Bd6 13.Nbd2 Rhe8 14.b3 Nd5 15.Nc4 where Black has an edge.

6...Qxe4+

If, instead, the weaker 6...Kxf6, the game takes on a resemblance to the Jerome Gambit after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5 Kf8 6.Nxc6 dxc6. Amusingly, in the Spanish Game the White Bishop is exchanged on c6 and the Knight is sacrificed on f7, while in the Jerome Gambit the Bishop is sacrificed on f7 and the Knight exchanged on c6.

7.Kf1 Kxf7 8.Nc3 Qf5 9.h3 Bb4 10.a3 Bxc3 11.dxc3 Nf6

White's compensation for the piece is negligible. His timid play hastens the end.

12.b4 Be6 13.Bb2 Bc4+ 14.Kg1 Rad8 15.Qc1 Rhe8 16.Kh2 Re2 17.Re1 Qxf2 18.Rf1 Qxg2 checkmate

I probably will continue to investigate the "Ruy Lopez Jerome Gambit" for historical purposes (and I have added the couple hundred games that I have uncovered to The Database), but after tomorrow's post –  letting a self-styled "hopeless patzer" have the final words – I will not inflict it further upon readers.
