About the Danish Gambit Accepted
After 1.e4 e5 2.d4 exd4 3.c3, Black takes with ...dxc3. White gives one or two pawns for very fast development and two strong bishops.
After Bc4 and Bxb2, both bishops aim at f7 and g7.
Black's safest defence is to give back a pawn with ...d5.
Greedy Black play can lead to a fast mate, so develop first.
