It's probably not sound. I imagine you'd have to look at correspondence chess to get some good ideas because OTB no one is touching it.
Is the danish gambit sound?

As a gambit with 2 sacrificed pawns, it's surprisingly good! It's evaluated by engines at approx. -0.5/-0.6. The best continuation for black is 5...Nf6! In the most popular Schlechter defense 5...d5 white takes back 1 pawn and almost equalizes.

What about if you were to sacrifice two pawns in the smith Mora?
The line would go:
1.c4 e5 2.d4 cxd5 3.c3 dxc3 4.Bc4 cxb2 5.Bxb2 *

Another problem is that if Black takes one pawn and refuses the others White has to play a Goring gambit. So the Danish isn't even a complete answer to 1...e5. You may as well just play the Goring...

5. ...Nf6 loses outright. Beware of false claims.
5. ... d5 equalizes after 6. Bxd5 Nf6
A wonderful gambit that is good for a win for White when Black is unfamiliar.

Probably not sound. In addition, Black can easily decline it with 3... d5
It might be strong though against unprepared opponents.

Best play by Black and a draw. So what else is new ?
Although after 5. ...d5 it is White on the short end of it in a positional game.

At your level, if you don't blunder a simple tactic, you'll win all the games you play with this opening. Or any other opening.

Say what ???
Just why is White forced into playing the Goring?
The Goring is probably more sound than the Danish and I enjoy the hell out if it too.
eta: Literally just started and finished this one in the last hour. A well known trap. It's very easy for black to get himself in trouble.

It should result in a wild game. If you enjoy wild games, by all means play it. You'll win some, you'll lose some, and you'll have a lot of fun in the process.
But you'll probably never see it played at master level.

The danish is generally not sound at top level. I would totally recommend it in club games, blitz games, or anything for fun. If black knows what he is doing he equalizes relatively easily and will probably have a slightly better endgame.
The main line in which white regains the 2 pawns but loses his bishop pair and is slightly worse. However, most e5 players don't really study the danish thoroughly and will probably not play 6.d5!
I prefer as black to play 3.d5 and simply avoid it. I like the resulting positions for black, and if you want to try the Danish, you have to look at this line as well.

Black can play 1.e4 e5 2.d4 ed 3.Nf3 Nc6 4.c3 dc 5.Bc4 and now either 5...d6 or 5...Bb4 decline the Danish and White will have to capture on c3.
the hyper aggressive danish gambit:
1.e4 e5 2.d4 exd4 3.c3 dxc3 4.Bc4 cxb2 5.Bxb2 *
It loooks insane, sacrificing two pawns within the first 5 moves. However, the two bishops look menacing. Does anyone play this or know weather this is as crazy as it looks?
