Actually the Grob Opening isn't an opening you should underestimate.
For a long while the below position was considered a deadly trap.
White players would leave the g4 pawn open to be taken willingly in order to do a trap.
They would follow up with the move 3.c4 setting a trap!
If black took on c4 with 3...dxc4 they would lose the b7 pawn because of the White light square bishop.
Which is shown below:
If black played a different move like 3...c6 instead of taking on c4.
White would respond with adding extreme pressure! Usually involving some sort of Qb3 move such as below:
Notice how in both cases the queen coming to b3 is the key factor here which does a double attack on d5 and b7!
In fact, this position was considered so uncomfortable that many black players refused to play 2...Bxg4.
They wished to avoid this sort of stuff completely.
Instead they played other moves at move 2.
Not so long ago GM's were trying out different lines in this 2...Bxg4 variation.
I don't know why, but they did.
They than tryed the move 3...d4.
Which at first doesn't seem that bad.
However, It does set up some deadly counter traps of its own believe it or not!
For example:
Now at first glance you might not see it.
However, if you look carefully the idea the black players had was in connection with the bishop on g4!
You could image a situation were the D pawn gets to d3 at a very awkward time.
If it did get to d3 than the white d2 pawn would be pinned!
Since the black bishop on g4 would attack the white queen!
I remember a game which had the follow moves.
In fact, the below game had almost the same moves as Pfren example on post #30 with one huge difference!
The player playing white didn't play 6.f3!
They played the normal looking move 6.Nf3.
White ended up losing this game.
I will not show the whole game because I can't remember it all.
However, I do remember the kool part of when the deadly move d3 came in!
Black than went on to win the game.
If you count the material.
Both sides have 6 pawns.
White has 1 rook
In exchange
Black has 2 minor pieces
Black eventually converted the material advantage to win the game.
And now you know why they play 6.f3!
White went from being the Hunter.
Into becoming the Hunted!
Becareful when you set traps.
You might end up falling into your own trap!
Yeah, I don't think putting the Queen on the long diagonal and taking a square away from the Knight is where you want to be going strategically, and chesster's suggestion seems very good for Black since he gets a big lead in development.
but g5 attacks knight followed by b3. You immediately place black on defensive and can keep it the rest of the game if you know what you're doing haha.
If you know what you're doing then you're not playing this pile of shite in the first place haha.
