David Bronstein and the King's Gambit
According to the articles, David Bronstein was a large influence in bringing the King's Gambit back into popularity. The articles are very interesting and a must read for anyone interested in the King's Gambit.
In Part 2, Gserper posts several games which are excellent examples of Bronstein playing the King's Gambit. These games would be worth anyone's time to study. The "Counter Gambit" group is meant to be used as a tool for studying Gambit play and I can't think of a better Gambit to study that the King's Gambit. I hope you enjoy these as much as I have. Here is the first game that Gserper posted. Just follow the above links to see the others.
