It looks like this:

Variants include:

9...Be6 Qh5+ (Normal Variation)

9...Bf5 10. Re1 (Bishop-Knight Pin Variation)

9...Bg4 10. Re1 Be6 (Queen-Bishop Variation Accepted)

9...Bg4 f3 Be6 (Queen-Bishop Variation Declined)

And what do you accomplish by sacrificing all those pieces?

Ok, but what about 3. Nxe5 (instead of 3. Bc4)?

This is called the Damiano (2. ... f6) and white will play Qh4+ if 3. ... fxe5. 4. Qh4+ and if 4. ... g6 5.Qxe5 winning the exchange as Rh8 will fall. Otherwise 4. ... Ke7 and still 5. Qxe5 and white are much better placed anyway

Hey its a really new one plus you got a good Q+R mating combo... I'll leave it up 2 u 2 move the queen

some  advice is to stick to the opening analysis already done by all the GM's and masters and study them rather than try and create something new. As if its not already been played/named/studied then its not good enough

the dutt gambit and all variations are probably gonna become one of those openings not played often like vienna game and one of those which makes you lose like halloween gambit... i see everybody elses points, but i also see mine, i am like that

---

that is very wrong we should creat new openings new moves then how we will be good players         chess is not studying only

and after? what middle of game? i'll never play this openning...

In this variation play 3. Nxd5!!

I am sorry but that is not new

---

First learn to play a little bit better than total beginner level (like don't give away pieces at random), THEN think about creating new things.

 That is old, it is an old fork/scholar's mate

Openings are a little more than simply throwing pieces at pawns and then charging with rooks.

this

In the first game that was posted, after 10. Re1+, there isn't any real danger. Black can play 10... Ne7 and there's no positional advantage (maybe a tiny bit for white) and black is up a bishop, a knight, and a pawn. Unless black makes a very stupid mistake, white is going to lose.

Not true. (Although in this case, a good application.) An excellent example of good opening theory shunned by grandmasters is the Bird's Opening. Black will be able to do no more than reach a drawn position with correct play, and yet very little has been analysed. Anyone could come along and suggest a new, excellent move to add to the theory.

is it really effective?

Clearly the Butt Gambit would be a more proper name. Both players would have to be complete buttheads to play it.
