Some are not.
eltemible - DJJDev
blitz, FICS, 2011
1.e4 e5 2.Nf3 Nc6 3.Bc4 Na5
That unnamed "line of play that everyone should know about".
4.Bxf7+
For the record, 4.Nxe5 is best.
4...Kxf7 5.Nxe5+ Ke6 6.d4 Bd6
I don't have anything against the move ...Bf8-d6 in the abstract; I am sure that sometimes it is an ambitious move (I am thinking of the Four Knights Game), but as in the Jerome Gambit game HauntedKnight - sarahdaniel, blitz, FICS, 2011 that we looked at a short time ago, and as in the Blackburne Shilling Jerome Gambit game HJBuck - fastglass, blitz, FICS, 2011, it is also a poor fit in this related line: Black does better with 6...d6. See "The Psychology of Error in Chess".
7.Qg4+
Simply the beginning of The End.
7...Ke7 8.Bg5+
Okay, it seems that The End has been postponed. It was expected to arrive with 8.Qxg7+ Ke6 9.Qf7 checkmate, but it still is not far away.
8... Nf6
The sad alternative was for Black's King to step aside and let his Queen be taken without even the recompense of recapture, as 8...Ke8 9.Bxd8 Kxd8 loses a Rook to 10.Qxg7. Painful.
9.Bxf6+ gxf6
As above, "best" was 9...Ke8 10.Bxd8 and again 10...Kxd8 would lose a Rook to 11.Nf7+.
It is no wonder that Black chose a faster exit.
10.Qg7+ Ke8 11.Qf7 checkmate
It is not as if DJJDev had not been warned. A year and a half ago he had played 6...Bd6, and his opponent, Jerome Gambit Gemeinde member UNPREDICTABLE, had also found 7.Qg4+, although after 7...Kf6 The End was again postponed – if for more moves, then also with more pain – 8.Qh4+ (or 8.Bg5#) 8...Ke6 9.Qxd8 Be7 10.Qxc7 Nc6 11.d5+ Kf6 12.dxc6 bxc6 13.Nxd7+ Ke6 14.Qxc6+ Kf7 15.Ne5+ Kf8 16.Qxa8 Nf6 17.Qxc8+ Ne8 Black resigned.
