When I first started to learn chess I was introduced to the King's Gambit.
I do not recall ever playing it in a tournament or in college.
I still own a Batsford by Korchnoi on the subject.
Bronstein's 200 Open Games contained a few KG's.
What I am looking for beside Chessgames.com or Chesslive.de
is King Gambit sites. Even books.
Some of the sites:
5 annotated games on the KG by Jan van Reek.

An article by Bobby Fischer:

In the summer of 1961, a new chess magazine, the "American
Chess Quarterly," began publication. Edited by Grandmaster
Larry Evans, it was "dedicated to the interests of the
professional chess player." The first issue contained an
article which not only put the magazine on the map, but which
became one of the most famous opening articles ever written.
Eighteen-year old U.S. Champion Bobby Fischer was smarting at
the recent defeat handed him by Boris Spassky at Mar Del Plata.
Bobby had played the Black side of the King's Gambit.

The chess game between "Kronsteen" and "McAdams" (actually
Bronstein - Spassky) appeared in "From Russia With Love" (James Bond).

Hey Malbase,
i recently bought ''The Fascinating King's Gambit '' book by Thomas Johansson. It does not however cover 3.Nf3 but rather aimed at 3.Bc4. Covers Kings Gambit declined and has lots of different chapters. The book itself has large pages and good big clear diagrams.
As far as i know Johansson also wrote the Kings Gambit - ''Creative Aggressor'' and in this book he discusses 3.Nf3. The reason behind the 2nd book ''The fascinating Kings Gambit'' is that he reckons that after 3.Nf3 black can cause white problems with the Kieseritzky line. There is also little published on 3.Bc4 where as i said here before Bronstein said if you want to play Kings Gambit, if you play 3.Nf3 black can draw, play 3.Bc4 if you want to win!
I also came across some older Kings Gambit books in the second hand section of 2 recognised chess shops in London that were only a couple of pounds each. They seemed pretty good to but maybe a little dated?!
I actually have Neil McDonalds ''The Gambit:A modern view...'' on order(to add to the collection!hehe) but i have not seen great reviews. In fact i may cancel the order :s

Basically, if your willing to try 3.Bc4 'the fascinating kings gambit' is definatley the book for you. If you dont want to try 3.Bc4 then the other Johnasson book is probably your best bet.
