Danish gambit almost never. Kings gambit 1 in 10 if that.
1.e4 e5 players, how often are you seeing the Danish and King's Gambits?

I say about 50% Ruy Lopez, and of the other 50% about 25-25. I don't know why so many people play the Danish Gambit though since you can just grab both pawns and wait for white to lose. Also, with the King's Gambit is easily answered by 2...d5 3.Nf3 exf4 with a game where the better player wins.
Both of them pretty rarely, maybe 1 out of 10 opponents and generally when I meet someone who plays one that's just about all they play. King's much more often than Danish, and I'm not sure I've ever played against the Danish giving up only one pawn.
For those who play e5 in response to e4, how often do you encounter the Danish gambit, the half-Danish gambit (with only one pawn gambited), and the King's Gambit? Which one do you encounter most often and which one least?
