d5 or 6 is what i play....why are u missing something ?
King's Gambit Accepted?

Pretty much anything goes: d6, d5, Be7, Ne7, g5, and so on...
I like 3...Ne7, but it's rather a matter of taste and ambitions.

Probably without giving the knight away for nothing.
Don't worry so much about individual moves, but the overall plan of where you want your pieces and stopping your opponents plans etc.

This opening is extremely dangerous for both sides and should be played by those experieced w/ it. Is this an active game ?

Check out Modern Chess Openings - 15 which gives a number of important variations. It's the first opening addressed in this version of the book.

Check out the games of Paul Morphy, he played some nice King's Gambit games both as white and black.

Don't forget, you can also play 3.Bc4 instead of 3.Nf3 which leads to some less well known positions but still absolutely playable below at least IM level. There is a book called The Facinating King's Gambit that specialises on the King's Gambit Bishop's Gambit.
The key thing about this line is that many of blacks defences against 3.Nf3 are just plain bad against 3.Bc4 so you can often get great positions very early because black tries to transpose but fails. If you're worried about the Queen Checks, Don't worry after 3.Bc4 white can move the king to f1 and the time wasted by black to deliver the queen check often comes back to haunt him as he will have to move the queen at least one more time or white can play Nf3 gaining even more time.

True. :)

Basically they key thing with 3.Bc4 is that it allows (or rather, provokes) 3...d5 which gives Black a very good game.
Is this right?
