danish gambit

why danish gambit not played by top player... is it unsound or unclear?

e4.e5 2.d4..exd4  3.c3....dxc3   (Qe7 may ma be slightly better for black  4.Bc4..cxb2   5. Bxb2.. d5 (Bb4+ fights for an advantage)   6.Bxd5..Nf6   7.Nc3...Nxd5  8.Nxd5..Nd7 (c6 Nf6+-) is a wild position

Unclearish IMO

I think white doesn't prefer because of d3 variation.

Another thing too is Danish is easily refuted. There isn't much to this skirmish after trade of queens in mainline. Its a very dead and unexciting game with no real play for either side.

1.e4 e5 2. d4 exd5 3. c3 dxc3 4. Bc4 cxb2 5. Bxb2 d5 6.Bxd5 Nf6 7.Bxf7+ Kxf7 8.Qxd8 Bb4+ 9.Qd2 Bxd2

not  7.Bxf7+

  7.Nc3!....Nxd5   8. Nxd5   is interesting for example  ...c6   9.Nf6+   1-0

and that's just one line. I'm not saying the opening isn't great for low level chess. Just that when I asked my coach this sane question he told me the pluses black has after 1.e4 e5 2.d4 exd4 3. c3 d3! Here c3 impedes whites development of knight, and while black sacrifices a pawn, whites position is somewhat disorganized.

I guess what I'm trying to say is everything is just to clear. The position is very open and because of this there is nothing really to do but trade pieces.

Thanks..Nekhemevich, for explaining this line 3....d3

but black rarely plays it.. as long as know I never play this line for black or white ..going to study it..lol!

Here are the two founders/advocates of the Danish Gambit playing. From plays 3...d3 and wins.
