Move by move

1.e4 – White occupies the centre and frees the queen and the f1-bishop. In the Danish and the Centre Game, speed of development will matter more than pawns.
1...e5 – Black replies symmetrically, contesting d4 and freeing the f8-bishop. Now White can open the game at once with d4.
2.d4 – White attacks e5 and opens the centre. After 2...exd4 White chooses between the gambit 3.c3 (Danish) and the immediate recapture 3.Qxd4 (Centre Game).
2...exd4 – Black captures: the most natural reply, since defending e5 with 2...d6 leads to a passive game. The d4-pawn becomes either bait or a target to win back.
3.c3 – Danish Gambit: White offers a pawn to open files and diagonals. After 3...dxc3 a piece recaptures with development; if Black declines, cxd4 builds the ideal e4-d4 centre.
3...dxc3 – Black accepts the gambit. White now chooses: 4.Nxc3 plays just one pawn down, while 4.Bc4 offers the b2-pawn as well.
4.Bc4 – White leaves the c3-pawn and develops the bishop against f7, Black's weakest point. After 4...cxb2 the other bishop also joins the game by recapturing on b2.
4...cxb2 – Black takes the second pawn. In return White gets two bishops aimed at f7 and g7 and a big lead in development: every tempo Black wastes can become decisive.
5.Bxb2 – The typical Danish position: two pawns down, but the bishops on c4 and b2 hit f7 and g7 while Black has developed nothing. White aims for Nc3, Nf3, O-O and opening the game.
5...d6 – A solid but slow move: it frees the c8-bishop and controls e5, but leaves f7 defended only by the king. White hits the weak point at once.
6.Qb3 – The queen lines up with the c4-bishop against f7, so Bxf7+ ideas become threats. Black must defend f7 immediately and loses more time.
6...Qe7 – The queen defends f7 but blocks the f8-bishop: Black's kingside stays jammed and castling gets further away.
7.Nc3 – Development with a threat: Nd5 would hit the e7-queen and the c7-pawn.
7...c6 – Black takes d5 from the knight with another pawn tempo: after seven moves only the queen is developed.
8.O-O-O – Long castling: the rook lands on the d-file at once and presses on d6. White prepares Nf3, Rhe1 and e4-e5, but must watch the open b- and c-files in front of the king.

How to exploit the position

White is two pawns down, but the b3-queen and c4-bishop keep Black tied to the defence of f7, while the f8-bishop and g8-knight are still at home. The white king on c1, however, is exposed on the open b- and c-files.

Nf3 and Rhe1: finish development and bring the second rook to the e-file against the e7-queen.
e4-e5: with the d1-rook behind it, the push hits d6 and opens the d-file.
Ba3: the bishop attacks d6 with the e7-queen behind; Black cannot free the game with ...d5 without losing material.
Protect your king: Black will answer with ...Nf6, ...Be6 against the b3-queen and ...b5; keep Kb1 and Qc2 ready.

Master tips

The battery against f7

With the bishop on c4, the queen on b3 turns f7 into a target: Black must defend it before developing the kingside.
