I regularly play it & have the book by Hall & Smith.
It's good fun, but there are rather obvious ways for White to achieve a very good advantage in the main lines.
I've noticed that 1.d4 e5 2.dxe5 Nc6 3.Nf3 Qe7 4.Bf4 Qb4+ 5.Bd2 Qxb2 6.Nc3 Bb4 7.Rb1 Qa3 8.Rb3 Qa5 9.e4 is easily found even by sub-1500 players in blitz.
The best Black can do here is hope for a miracle.
As I say, it is fun though & will take White out of book very quickly in most occasions.
