Chesstainment: I call this the isolani gambit

This is in no way a recommendation, it is simply some fun. The opening variation I will show you is by no means equalising, in fact the best you can realistically hope for is to be slightly worse, so play it at your own risk. With the small disclaimer out of the way let's move on to the actual line, and some analysis I might do a few more posts analysing this or other equally dubious lines if this is a success.

1. Nc3 d5 2. e4 dxe4 3. Bc4 Nf6 4. d3 exd3 5. cxd3

in fact that last move

 5. cxd3

is probably not the best, since you can probably play Nf3 and have a reasonable position, however that is not the thing we are looking at.
taking the pawn on d3 with our pawn is what defines this as the isolani gambit.
I think the most natural move here for black is the natural looking Bf5, and this could lead to a fascinating mate, though very unlikely.
Now however the reason for whites rather silly cxd moves become much clearer as we play Qb3.
With Qb3 we do setup a strong attack on both f7 and b7, black could make a mistake here and fall into the same mate as I will show a little later but in a different equally comical way. To do so here he simply defend b7 with the bishop thus Bc8 leading to the mate.

1. Nc3 d5 2. e4 dxe4 3. Bc4 Nf6 4. d3 exd3 5. cxd3 Bf5 6. Qb3 Bc8 7. Bxf7+ Kd7 8. Qe6#

The same mate happens if black takes the pawn on d3.

1. Nc3 d5 2. e4 dxe4 3. Bc4 Nf6 4. d3 exd3 5. cxd3 Bf5 6. Qb3 Bxd3 7. Bxf7+ Kd7 8. Qe6#

Black can also play in a different way which is perhaps more striking, that he will have to move his king to d7 to prevent material loss, however black will have to make several rather suspect moves for this to happen, so it is exceedingly unlikely it would occur in a game.

1. Nc3 d5 2. e4 dxe4 3. Bc4 Bf5 4. d3 exd3 5. cxd3 g6 6. Qb3 Nd7 7. Qxb7 e6 8. Bb5 Rb8 9. Bxd7+ Kxd7

But black played many silly moves in this variation, and even then the king is not so badly placed on d7, in some cases it can be quite safe on d7. The computer gives this a slight edge for white, even with the King on d7 this is essentially making any hope of salvaging anything useful from this a completely waste of time.

There is however another line I had some fun thinking about.

Though it is not a solid line, I just had some fun.

1. Nc3 d5 2. e4 dxe4 3. Bc4 Nf6 4. d3 exd3 5. cxd3 Bf5 6. Qb3 e6 7. Qxb7 Nbd7 8. Nb5

There is however some problems for one Bb4+ gives black excellent play, as he forces whites King to move and then he simply castles out of any problems.
Also Bd6 is a decent move for black, however chaos does occur if black decides to chase the queen with Rb8 then madness can arise on the board.

But nevertheless this is not a playable opening, just a few funny thoughts, Nb5 is decidedly not a good move but even the position before this black plays somewhat reasonable and he will maintain a slight edge white has simply weakened his position to much by giving up one pawn and isolated his d-pawn and made it somewhat backward.
