1. d4 ... d5 2. e4 ...

is there a name/resources for this opening?

i play it occasionally just for a break from my normal repetoire, and occasionally get fantastic attacks out it, the idea to then play f3, and try to retake with the king knight, almost like a staunton gambit, except with the black queen pawn instead of the king bishop pawn. 

That is called the 'giveaway, my opponent might rattle' gambit.

1. d4 d5 2. e4 dxe4 3. Nc3 (3.f3?! e5!) Nf6 4. f3 exf3 5. Nxf3 (Qxf3!?) is the "Blackmar Diemer Gambit". Fun to play but I'm not too sure of its tournament value.

I think your talking about the Blackmar-Diemer Gambit, it's fairly popular so you should beablr to find info online about it.

I know playing f3 right away is good ofr black

The BDG Keybook II by Tim Sawyer is probably the best resource.  I would also check this link http://www.geocities.com/Athens/Acropolis/4902/  This will give you a lot but I don't think its been updated a lot lately.  It very good for a solid understanding of the BDG.

thanks for the help everyone!

Its the Blackmar gambit (1 d4-d5; 2.e4). It's fantastic, but a central pawn is a central pawn! http://www.ecochess.com/d00d99/d00d09/blackmar.htm

vonpopuil is a better line

1.d4 d5 2.e4 dxe4 3. nc3 nf6 4. Bg5...... there so many good ways for black to trap itself. its great

dream on when you think 4.Bg5 is better than 4.f3...you threat nothing and the best you can hope is to switch to the french defence.

The BDG keybook is a good choice but it is not state of the art because its a few years old and it is a little bit too optimistic for White.

My recommendation would be the new BDG-book of Christoph Scheerer.

Wow...what a source...i can give you thousands of databases where the BDG has by far the best winning ratio for White.

For example look at the opening explorer on this side.

Fact is, that the BDG is not popular on master level, but very popular on amateur level.

My opinion is, that with best play from both side, White cannot hope for more than a draw, but the BDG is a theoretical monster for both players. One step (move) in the wrong direction and your position is busted...

I play this opening with great success, but on higher levels it will probably fail to achieve good results, because the defence skills of master players are very good.

Well you can always transpose it into the french or the caro-kann with e6 or c6 which is what I do,

and then you will face an other gambit line...Diemer-Duhm, Alapin, Aljechin-Chatard, etc...

well ya but if you are not very confident about playing against d4 d5 e4, the best choice would to just play c6/e6 after e4.

If black plays Qg4 then Qf3 (?!) sucks majestically

As Black I like 1.d4 d5 2.e4 dxe4 3.Nc3 c6 transposing into a Caro-Kann, where 4.f3 and 4.Bc4 are both pretty weak moves, so White should choose 4.Nxe4.

It's an interesting gambit if accepted, but Black has a number of viable defenses. It's probably too risky to play at a competitive level.

Thats correct...
