When two pieces beat a queen

I got the title from Tim Harding's column "The Kibitzer" on chesscafe.com.
Really interesting stuff after 1.e4 c5 2.f4 d5 3.Nf3 dxe4 4.Ng5 Nf6 5.Bc4 where terrible complications occur after 5...Bg4.

White now has 6.Qxg4 Nxg4 7.Bxf7+ Kd7 8.Be6+

The gambit is called "Bryntse gambit" and leads to a great white attack. The complete doc is at chesscafe.com.

Anyway, maybe an alternative if you were to consider dropping the Blackmar Diemer.
