Grob's Attack

Thank you DGrabrielRosa! But you see, with low rated players it worked in that post... And that's the point. I love QGR for white and black, and french as black against e4. But they are slow positional openings. In over the board tournaments i get some younger players, full of blitz moves and studied openings. I need something completely unusual, out of confort zone, and tricky as hell. if it would be classic timers i didn't risk it, but in a 15+0 min... does this opening work? By work i mean, can give me killer moves without i get a checkmate before?

@Yigor But works? You play against opponents medium/high rated? which time control you have when you play it?

Hmm ... I just checked and I have the excellent score of 10 wins out of 13 Grob games here vs medium rated players (daily games).

Grob got me to 1830, thank you Henri Grob.
Don't listen to the haters, they hate losing to the Grob, that's what they really hate.
A Grob player can usually gain an advantage in blitz if for no other reason then the fact that people do not study Grob like they should and do not know its ways, whereas I spent afternoons perched over a chessboard considering "What if Black moves this? How do I counter?" So I have a response for anything Black tries, go ahead make my day.
Not playable for long games against the tough or titled, though, because ultimately the computer knows the weak points and the big shots memorize them. Once a big shot has been humiliated by a lower ranking player, yes they take the time to memorize against even the obscure Grob. I watched a documentary by this GM or IM who basically showed how Black gets the advantage. So, they know, but they spend their whole life studying the game, so they have all that book lore and are forced to play a pretty narrow range of openings at their level. No more wild gambits for that lot.

@talapia thank you for your comment! i agree with you, lots of players says it is bad because top gm don't play it. Of course, it is bad if you know how to counter it. In a 15min game, over the board, you have to find the moves. At least the clock will run faster for them. It has alot of tricks, and with smart kids that know 15 moves of sicilian, it may be a hard surprise! The streamed games i saw... Well played is very strong... Chessbrah has a video with all games being grob attack/defence...

Yes, i agree @yareyarewawa! It isn't forgiving for white. The g4/c4 opens both castles, and if you lose iniciative... this is a 20/30 winning moves game. my point is, if they blunder they lose and lose for a opening that everyone says are bad, destroy them mentaly and provoke more blunders and less focus. first i'll try it online, see its performance

I haven't had that perception... Even in a 15min my oponents find best moves? It is my fear for sure...

Go watch, final nail on the coffin for the grob by Miodrag Perunovic, he shows how to easiliy get an advantage against the grob, at the end is white who has to defend a weak position.

It's funny how the same people who uses theory to learn a bad opening as the grob, gets mad when others use it to punish it.
And it's not even hard! It can be done whithin half an hour.

IM Michael Basman played it in tournaments and wrote a book about it:

He even played it as black with a tempo less: here is a game against a GM in the British Championship

Basman insisted that white should not push g5, but reinforce g4 with h3 instead.
Anyone here uses grob's attack? I'd like to study deeply this lines for surprise low rated opponents (<1350) in over the board tournaments in my 15+0 games. I want to know if it is solid enough for a real try or if it is simply suicide. Where can i find more about it?
