Another "Optical Illusion" Variation?

I've already collected too many points from the "Optical Illusion" variation of the Jerome Gambit (see "Optical Illusion (1)" and "Optical Illusion (2)" or the most recent "Disdainful Defender Defense") so I am uneasy about identifying a second position that has been gaining me points for something that my opponents do not see in the position...

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 h6 5.0-0 Bc5 

The Semi-Italian Four Knights Game.

6.Bxf7+

The Jerome Gambit response. I've slowly raised my score against this unfortunate (for me) line to 57% (still about 30% lower than my general Jerome Gambit score).

7...Kxf7 7.Nxe5+ Nxe5 8.d4 Bxd4 9.Qxd4 d6

White has a pawn for his sacrificed piece. Black is clearly better.

10.f4 Nc6 11.Qd3 Re8 12.Bd2

Now after 12...Kg8 it is hard to see any compensation for White, as Black has even been able to castle-by-hand.

12...Nb4

Absolutely fascinating. Black attacks the Queen – and loses a piece.

Seen previously was the similar: 12...Kg8 13.Rae1 Nb4 14.Qc4+:
perrypawnpusher - amirelattar, blitz, FICS, 2010 (1-0, 50);
perrypawnpusher - pwr, blitz FICS, 2010 (1-0, 38); and
perrypawnpusher - Angstrem, blitz, FICS, 2010 (but 0-1, 35 )

13.Qc4+

Black resigned

The final illusion: Black is losing a piece, but he already has one to give!

After 13...d5 14.Qxb4 Nxe4 the game would simply be even. There was no need for surrender.
