About the King's Gambit Accepted
After 1.e4 e5 2.f4, Black takes the pawn with 2...exf4. The game turns wild: White wants a big centre and an attack on f7.
White plays Nf3, d4 and Bc4, then opens the f-file to attack f7.
Black can hold the pawn with ...g5 or give it back with ...d5 for easy development.
Watch the e1-h4 diagonal: ...Qh4+ can be a dangerous check against White's king.
