Just out of curiosity: What is the Fritz evaluation of the position after a (I assume?) standard Grob Opening (1 g4 2 d5)??

-0.5ish?

Ok, I have fritz 9 running now, and it's giving it a -0.62 (slight advantage for black). That's with the move order 1.g4 d5.

Don't play it 🙂

I dunno about Fritz, but Rybka rates it about equal.

After 15 minutes have passed, Fritz 9 evaluates 1.g4 d5 as -0.57 (slight advantage for black). Here's the line:
2.Bg2 Nc6 3.c4 e6 4.Nf3 Nf6 5.0-0 dxc4 6.Qa4 Qd6 7.Qxc4 Qb4 8.Na3

hope this helps

Another edit, New line. -0.60 at 25 minutes.
2. Bg2 e5...

since we are in a forum using engines (which I don't have)
what after
1. g4 d5
2. Bg2 c6

does black maintain the advantage setting up a caro-kann type pawn structure in the center?
obviously, after this, the g4 pawn is hanging and black can take it safely...
and has the accepted been deemed as winning for white?
1. g4 d5
2. Bg2 Bxg4
3. c4 c6
4. Qb3
is this indeed a won position?

When i play Bg2, Fritz evaluates Nc6, e5, and c6 with approximate equal value. (-0.58). After c6, Fritz likes 3.g5 with (-0.61)

After the line you gave me, it gives 4...Qd7 with -0.61 for black. haha.

I would not trust these values too much. I would say Rybka does much better job in evaluating positions, and so roughly equal as Korch said.

i always heard that black accepting the g4 pawn was a losing blunder...

I'm not familiar with Grob Theory, but Fritz thinks otherwise 🙂

Nop. In my opinion black should not sacrifice on g4, but play g5 or h3.

Right you are. I have anlysec this sac on rybka and concluded that white can get clearly worse position if black knows how to play. But if white decides not to sacrifice this pawn they can get normal game.

Engines don't give very useful information 2 ply from the standard position.

I analysed these positions deeply.
