Kieseritzky Gambit: 3...g5 4.h4 g4 5.Ne5 is variation 1 of 5 in the King's Gambit course, a advanced opening course for White (ECO C39). It runs 25 moves and begins 1. e4 e5 2. f4 exf4 3. Nf3 g5 4. h4 g4 …. White answers Black's ...g5 chain with h4, then jumps into e5 when the f3 knight is kicked. In the main line both sides trade into an endgame where White's pieces are active and Black's kingside pawns are loose. In the lesson every move is explained on a board and then drilled; it is free.
Move by move
1. e4 – Takes the centre and opens lines for queen and bishop.
1... e5 – Black claims the centre.

6. d4 – Builds the centre and opens the c1 bishop to recapture on f4.

7... Nxe4 – Black grabs the centre pawn.
8. Bxf4 – Regains the gambit pawn with a well-placed bishop.
