...which I translate in "Yes, your opening is rubbish!" I suppose ? ^^
How about real queen's GAMBIT?

Ok, now that makes sense. Maybe it can serve in blitz IF your opponent tries too hard to punish you right away.
Here's where I got the "b3" idea:
1.d4-c5 (old benoni) 2.d*c5-b6!? 3.c*b6-Q*b6
It looked fine for black so I wondered if it was playable with white. The problem is with the loss of the d4 pawn...
What do you think of this line as black?
I've been thinking about the following moves, which I can't find on shredder database nor in chessgames:
1.d4-d5 2.c4-d*c4 3.b3!?-c*b3 4.Q*b3!?-Q*d4 5.Bb2
The idea are:
-sacking two pawns, which is always fun in the opening
-throwing black off his chair
-gain advance in development
-make it difficult for black to develop (the Qb3 prevents the c8 bishop from moving)
-trying to get a set-up like this one (?)
What do you think? Interesting? Rubbish? (okay it's probably rubbish)
Please note that I tried to choose sensible, but "still-grabbing-the-two-pawns" moves for black, which is what an opponent might try when confronted with 3.b3
If he doesn't the game should be just fine for whitel
