Bareev has played both 7...Bxf6 and 6...Nbd7 with success, but these approaches can hardly be labelled as energetic. They are probably a tad better than the plain Rubinstein, but no more than that.

I've played the gf6 and b6 variation four times in the past, and scored quite well- three and a half points (the half point doesn't really count, as it was against my wife). But then it was the pre- Morozevich era, and ...a6 was hardly considered as a serious option.
