About the King's Gambit Declined
After 1.e4 e5 2.f4, Black refuses the pawn, usually with 2...Bc5 or 2...d5. This avoids White's main attacking lines.
The bishop on c5 stops White from castling short easily.
2...d5 (Falkbeer) hits back in the centre right away.
Black develops normally and watches the f-file and the a7-g1 diagonal.
