Bishop's Gambit: 3.Bc4 is variation 2 of 5 in the King's Gambit course, a advanced opening course for White (ECO C33). It runs 19 moves and begins 1. e4 e5 2. f4 exf4 3. Bc4 Nf6 4. Nc3 c6 …. Instead of Nf3, White develops the bishop toward f7 and does not fear ...Qh4+. Against the solid 3...Nf6 4.Nc3 c6 White keeps a flexible centre and regains the f4 pawn with Nge2xf4. In the lesson every move is explained on a board and then drilled; it is free.
