44 ( +1 | -1 ) This is an imaginative defensewhich tames the king's gambit. pk4- pk4, pkb4- qr5+, pkn3, qk2, pxp , pq3, pxp, qxp+, qk2, qxq ch (and the game is equal). there is also possible is: 4. N kb3, pxp, 5. Nb3, pq4. 6. Nxp, Qxp+, qk2, qxq+ bxq, bq3 (and the game is equal).
I ALWAYS use this defense against the king's gambit, with the aim of taming the gambit. You better play some relatively long blitz games with this variation and see how you manage with it. The classical variations of the KG are more dangeours, one mistake as black and HASTA LA VISTA BABY.
55 ( +1 | -1 ) Keene VariationThis is a major response to the KG, but objectively about the same as other defenses.
Today the standard way of meeting 4. fxe5 d6 is with a simple 5. Nc3/Nf3/Bc4 setup, leading to positions more analagous to a normal KG.
4. Nf3 is hardly ever seen, but 4. Nc3 (probably now the main line) leads to similar positions with much more room for flexibility, e.g. 4. Nc3 exf4 5. d4 fxg3 6. Nf3 d6 7. Bg5 f6 8. Bf4 Nc6 9. Qd3 Qf7 10. 0-0-0 Nge7 and White has a lot of development for the pawn (Stokec-Vokac, 2001).
The other major response is 4. d3, which is more or less equal after 4... d5 5. Nc3 Nf6, maybe White has a slight pull.
