hello i think this line is a subvariation of the so called fischer gambit in the english defence... you can search this variation in CBM magazines inside the mega 2003 database... this will solve all your problems regarding the variation i usually play with this variation with black against strong players here in the philippines...(GM's Notably)

Mabuhay fom Philippines,,!!!! Anagua on ICC

Is this line refuted, I find this line very difficult for black to play, he must be accurate, and patiently aggressive, as well as damn brave to take this on.  the line goes like this.

1.d4 e6 2.c4 b6 3.e4 Bb7 4.Bd3 f5 5.exf5 Bxg2 6.Qh5 g6
7.fxg6 Bg7 8.fxh7 Kf8 

9.hxg8 is given a question mark by King
Instead 9.Bg5 Nf6 10.Qh4 Bxh1 11.Nd2 Nc6 12.Ne2
after all of this craziness, I think that white has the better practical chances, and I have given up playing 5...f5 altogether in place of 5...Bb4+ and 5...Nc6.

thanks
