Recently, Kingscrusher has been video-annotating the 11-0 sweep of Fischer in the '64 U.S. Championship (and I highly recommend his videos). While watching the game against Evans, Fischer employed the King's Gambit opening and won what seemed to me to be a creative and energetic game.
After watching, I played a few blitz games using this opening and have found the games to be a fun departure from the typical 1 e4 e5 games, which sometimes can result in symmetrical positions that are less interesting. The Gambit actually seems to have a fairly high success rate. I have noticed in my games that the system allows for:
1. White to take control of the center
2. Wild and Sharp play for both sides
3. and it has something of surprise value since it is infrequently played.
I have actually found this opening both fun and useful!
Although I do not offer my analysis as masterful, I have put up a couple of games that have some useful tips and ideas.
