A stamp of approval for the Kings Gambit

In the current Kings Tournament in Medias, Romania, World number 1 Magnus Carlsen pulled a surprise by using the Kings Gambit in his round 4 game against Wang Yue. Carlsen would certainly be the highest rated player ever to use this opening in a serious tournament game, and for fans of the opening, his opponent may well be the highest rated player* ever to lose to it.
Of course at this level the opening is played with a more positional outlook than the 19th century hack and slash style you see in club chess, which makes the game all the more instructive to lower rated players. Also worth studying is the ending where Carlsen was up the exchange. In one of his books on the middlegame, Euwe stated that being up the exchange in the ending was almost always winning, and Carlsen proved this to be so (even when his opponent had an extra pawn).

*Of course Fischer may well have been the 'strongest' player to lose to the Kings Gambit, in his game against Spassky at Mar Del Plata in 1960.
