I really don't know what to make of the following game...

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.Bxf7+
Okay, this is a sort of "Accelerated Semi-Italian Jerome Gambit" kind of thing. The Database has 1,739 examples; and White scores 40% - nothing majestic, but about on par for what happens in a large sample of Jerome Gambit games.
4...Kxf7 5.c3 d6 6.Qb3+ Be6 7.c4 Na5 8.Qb5 b6 9.d3
Now follows some foreshadowing.
9...Bd7 10.Qd5+ Be6 11.Qb5 Ke7 12.0-0 Bd7
Black has the standard extra-piece-for-a-pawn advantage.
One might think White would be comfortable with a draw.
One might be wrong.
Hold on, now.

Well over 100 moves have been made, and we're back to the same position. Of course, we have been there so many times, either player could have claimed a draw by repetition. In fact, a draw according to the "50 move rule" could also have been claimed.
Now White varies, claiming his disadvantage and eventually losing.
