King's Gambit - Queen's Knight Defense (2...Nc6)

Position after 9. Nbd2

Main line

The chapter's main line, with the comments from the course.

1. e4 e5 2. f4
Black takes the center, so we offer up our f-pawn for quick development and kingside pressure.
2... Nc6
The Queen's Knight Defense, Black defends the e5 pawn instead of taking our gambit.
3. Nf3
We develop naturally while keeping the pressure on e5.
3... d6
Black adds another defender to e5, determined to keep the center locked up.
4. fxe5
Black won't capture on f4, so let's clarify things and grab the f-file with our lead in the center.
4... dxe5 5. Bb5
We prep early castling to exploit our open f-file.
5... Bd6
Black defends the e5 pawn instead of harassing our king with Bc5.
6. O-O
Castling kingside as planned, making the most of our f-file pressure.
6... Nf6 7. d3
Solid pawn chain and room for our bishop, notice we play d3 here since Black's e5 pawn controls d4.
7... O-O 8. Bxc6
Time to double and isolate those c-pawns now that Black unpins.
8... bxc6 9. Nbd2
The knight aims for b3 or c4 instead of c3, where Black's c6 pawn would cramp it.
