Key ideas of Danish Gambit
After 3...dxc3 Bc4 cxb2 Bxb2 your bishops on c4 and b2 aim at f7 and g7: castle, then Qb3 or Qc2 and the rooks to the centre.
Black's best defence returns material with ...d5: know the simplifying lines and keep your pieces active.
Against ...d5 at move 3, exd5 Qxd5 cxd4 gives you a quick Nc3 and Nf3 with tempo on the queen.
Against ...Nf6, e5 kicks the knight and the c3 pawn recaptures on d4 with a strong centre.
The line trainer
The line trainer for Danish Gambit has 50 lines that grow out of 1. e4 e5 2. d4 exd4 3. c3, learned a few new ones a day with spaced-repetition review.
