By my count, it was 8 pieces captured after 8 moves (exactly 1 per move), but what I meant was that the variation we've entered is definitely leading to a serious advantage for one side. I'm just not certain which side is coming out ahead, at the moment.
On an unrelated note, I prefer to use '+' in place of "check", as in standard algebraic notation: 9. Qxe6+
I don't see anything obvious that we both missed, except that a piece seems to be captured almost every move. After move 8, seven pieces captured (almost 1 per move)!
