Did I invent something new?

Following on from the post concerning playing while sick, here is the second game played last Wednesday evening. It was against former Australian Girls Champion Emma Guo, and this is at least the third game between us that I've posted to this blog. I suspect this is because we have very similar playing styles, and a fairly similar opening repertoire so the games tend to be exciting (although often drawn).
The game started off with my usual transposition tricks (Sicilian Grand Prix until I switched back to the Open at move 5), but on move 7 I decided to try something different. This I guess is one of the side-effects of playing when ill, as Malcom Tredinnick presciently observed in a comment to the last post. Indeed I can remember thinking "What the heck" before moving my g pawn 2 squares. The game then went up, down and all-around as I won a pawn, dropped the exchange, launched a mating attack, and finally drew by perpetual. What was the most amazing thing however, was when I fed it into Chessbase it told me that 7.g4 was a novelty! Whether it is a good novelty might be for others to say, but certainly Fritz didn't find an outright refutation. So unless someone can point to an earlier game with 7.g4 I'm claiming precedence.
