Jerome Gambit: Move That Knight!

While looking for "secrets" in the Jerome Gambit - moves or lines of play that have been discovered or recommended, but rarely, if ever, used - I occasionally run across some ideas that deserve to remain secret, because they're not really all that good.

Let me share a couple, to show you what I mean.

What do you make of this line from weenar - Quixote, blitz, FICS, 2000 (0-1, 8)?

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Ng1

Wow.

White sacrifices his Bishop at f7 to disturb Black's King, and then decides that that is enough generosity for one day. Ah, but his King's Knight is in the way of his rampaging Queen - one of the benefits, he begrudgingly admits, of 5.Nxe5+ is that it opens the d1-h5 diagonal, admittedly at the cost of another piece. 

So, the solution presents itself - move the Knight home!

A similar idea (admittedly, not after a piece sacrifice) comes to mind in such lines as 1.e4 Nf6 2.e5 Ng8!?, the Brooklyn variation of Alekhine's Defense; 1.d4 Nc6 2.d5 Nb8!?; and Stefan Bucker's 1.e4 e5 2.Nf3 f5 3.exf5 e4 4.Ng1!? against the Latvian Gambit.

Not surprisingly, the 1 win that White has out of the 5 games with the position in The Database - is a time forfeit, when Black had a winning position. One plan for Black is 5...Qh4!? 6.Qe2 Nd4 7.Nf3!? Nxe2 8.Nxh4 Nxc1, and the Queens will be off the board as White tries to find compensation for his sacrificed piece (no worry, Black's Knight at c1 will fall, but White will still only have a doubled pawn as compensation).

But, let us not laugh too loudly. What do you think of the following line?

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Ng5+


Move that Knight!

This time: not so funny. There are 515 games in The Database with 5.Ng5+. Is it surprising, or not surprising, that White scores 24%?

One "idea" behind this un-blocking Knight move is that White simply didn't notice that his piece would hang - on the average, White's rating is about 100 points below his opponent. On the other hand, there are a significant number of games where Black does not take the Knight - an indication that we are probing the depths of club and blitz play, not grandmaster praxis.

Another idea is the pair of threats - should Black capture the Knight with 5...Qxg5 - embodied in 6.d4!?, attacking both the Queen and the Bishop at c5. It is a hallucination, however, as Black has the crushing 6...Qxg2 and White is in great misery, e.g. 7.Rf1 Qxe4+  8.Be3 Nxd4 - two pieces down, behind in development, King in danger...

Why do Jerome Gambiteers play this kind of stuff? Because it's fun, I guess.
