f3 is pretty poor, but it could turn into a solid hippo style opening. With g4 there is no solidity.

I know many people will disagree with this (and I used to as well), but I think 1 g4 is theoretically the absolute worst move on the board, even worse than 1 h4, because it creates more significant kingside weaknesses. But you have to get past the storm of confusion first. 1 g4 d5 2 Bg2 e5 3 c4 c6 (...Bxg4 is unnecessary.) is what I think the line is. I think black can get a strong center here and white's king will be in some trouble. Both kingside and queenside (which is also hard to organize) castling leaves the king a little insecure and outdone in the center, all that for some space! Maybe the king can stay in the center with some weird hippo formation with his king in the center, I don't know, but black without a doubt has the edge. If white plays h3, his kingside will be pretty weak without much to show for it.

if you open with the grob and black uses their kight to attack the pawn you can have a knight chase that if done right can keep the night running for at least 10 moves if you move the grob pawn forward to attack the knight.

i dont see this in your list but watched a little china- girl [6?] win at the iowa state fair useing this just last week and yes, some of the girls there were wareing  clothes that would make joss stone or brittney spears blush.

also their is no better place in the universe to eat a fresh corn dog or a polish pop sykle hahaha

It's a good fun attacking opening.  There are many easy ways for Black to lose.  And strong players do play it, actually: there are hundreds in my Fritz database of GM games.  Great fun.

There is a pretty good book on the GROB OPENING BY MICHAEL BASMAN published in 1991 if you can find it. Called "THE KILLER GROB" a paper back very good read. BASMAN a English International Master at the time the book was published.

It is mostly known as Grob's attack, but serious players do not prefer it.

One move that has been missed off here is 1...a5!? Which is an interesting reply and very dangerous if white Isn't careful! It's actually quite a popular reply too which is why I'm suprised not to see it listed here!

I won most of my games at a state tournament with the Grob!!!! It rocks!!

1.g4, is played by Awardchess, he beat me with it. If you had any questions about g4 he'd probably have a lot of knowledge to share on it.

Although, knowing Awardchess, what he replies really could be anything :)

RetG - Given that our sample size there is only three, I don't think you can actually say that G5 has any benefit. 

Interesting opening.  I agree with Gonnosuke, the second player must be cautious.  However, the chart shows that black's greatest success comes from 1. g4!? g5!!?

   Quite likely that is because white is taken off stride by the response. 

     I have faced 1. g4 once, and won (as black) fairly handily after 1. .... g5!!?     From the look on my opponent's face (sheer consternation), I believe that my response was quite unnerving to him and psychologically, he had lost immediately.

its all right if u follow with Bh3

Numerous traps require careful, cautious play from the second player.  In my opinion, it's a worthy addition to the arsenal of anyone who enjoys playing offbeat openings.  Limited value in correspondence chess; much more valuable (i.e. viable!) in OTB and blitz games.
