What are the strategic benefits to compensate for the fact that White's giving up the bishop voluntarily and so early in the game in the below variation? What does White hope to get back out of the opening?

    The immediate answer that jumps to mind is the tempo gained after 6. . . Qxd5 7. Nc3. If Black instead plays 6. . . c6 White returns the Bishop to b4 with a piece gained and little loss of time. Black will have options on the kingside, but he will be significantly behind in development, making it extremely difficult to capitalize on the (relative) weakness of White's exposed kingside.

I think Jonathan Garber's comment about trying to gain time against the Black queen after 6...Qxd5 7.Nc3 accurately describes what one motivation for 6.Bxd5 can be, though I also think that Black happens to have nothing to worry about in that regard. While she is temporarily behind in development, she shouldn't have any troubles completing her development, while letting the extra pawn on f4 go and simply enjoying her bishop pair on an open board. Being fuzzy about it, I'd say that all in all, everything evens out here, and we have a quite level game on our hands after 6.Bxd5.

I think another way to look at the reasons for 6.Bxd5 is in "what else?" terms. According to my database, the only more popular move in this position (though it is about 3 times more popular) is the sensible 6.O-O, but after the most popular response 6...c6, Black will be happy to camp out with a nice healthy piece on d5, until White sees fit to exchange it somehow. (This could be the same response to other moves as well, e.g. 6.Nc3 c6 and sit tight.) Perusing through some high-level games, it seems that White not infrequently ends up playing a later Bxd5 anyway (though certainly not all the time).

So, one possible takeaway: the position is already quite level after 5...Nxd5, and the immediate 6.Bxd5 is as good an option as White really has to try and create a favorable dynamic imbalance (of the sort Jonathan Garber mentions), even though IMHO Black has nothing to fear in this instance. One reason the King's Gambit isn't terribly popular at the highest levels - the occasional Nakamura game notwithstanding - is that Black does have some fairly reliable methods of defusing White's more ambitious prospects if she knows what she's doing, and this line for Black seems like an instance of that.

As an example of how things can go well for White, here's Magnus Carlsen using this line (by transposition) against Wang Yue. Around the time of 11.Qe2, we have the sort of balance described above, where White has a lead in development and more central space and control, but Black has safely castled and has nice bishops in an open setting. Then Wang Yue somewhat perplexingly engineers a bishop trade himself, and plays rather passively the rest of the way, letting Carlsen do what he does and make maximum use of the remaining White pluses:

    An excellent example and a much better stating of my thoughts than I gave. I can't play through the variations right now, but the perplexing Bishop trade seems at first glance to be a hasty attempt to avoid contention for c7. With the Black c-Pawn out of the way, Nd5 has the appearance of being a nuisance. Nov 2, 2012 at 13:38
  • Only thing I might add add is the the Black Nd5 holds the gambit pawn on f4, making White have to work a lot harder to regain it, and it also means White can't play the natural Nc3 (White sometimes wants d5 or e2 for this Knight, to help regain a troublesome pawn) without ruining his Q-side pawns. The point of this gambit is easy development, then regaining the pawn with minimal loss of time; Black's Nd5 prevents that.
