The f5 Opening

So? Some people like cutting themselves. That doesn't make it a worthwhile activity. And one imitates them at one's own risk.

Check out my last game from today (6/10/2013). I played the German as black and slaughtered white!!!

Isn't it self-refutable?
And I wouldn't label it as an "opening". "Closing" is quite more accurate a description.
Nah, "Gambit" is more like it. This is the "King's Counter-Gambit". Black Gambits the King!
Just like how after 1.e4 e5 2.f4??, it's White that's gambitting his King!
The opening has been refuted since the second page. You've just been denying it Shutter Island style ever since.

Someone want to refute my opening?
The other player playing badly does not make your opening sound.
nobody likes the german opening?
Nope.
