C21
Danish Gambit Accepted
6 named lines in this family, ECO C21. Every one of them opens 1. e4 e5 2. d4 exd4, so the notes on those moves are written once, just below, instead of once per line. Under each line you get its moves and the sentences it adds that this page has not already printed. A line's own page carries up to its first 4 per-move notes in full.
The moves every line here plays
1. e4 e5 2. d4 exd4
- 1. e4 Stakes a claim in the centre, controlling d5, and frees the bishop and queen.
- 1... e5 Stakes a claim in the centre, controlling d4, and frees the bishop and queen.
- 2. d4 Stakes a claim in the centre, controlling e5, and frees the bishop and queen. Theory calls this the Center Game.
- 2... exd4 Takes the pawn on d4, toward the centre. Theory calls this the Center Game Accepted.
Svenonius DefenseC21
1. e4 e5 2. d4 exd4 3. c3 Ne7
An early pawn trade leaves the d-file as White's avenue and the e-file as Black's - both sides get real winning chances down their own file.
Chigorin DefenseC21
1. e4 e5 2. d4 exd4 3. c3 dxc3 4. Bc4 cxb2 5. Bxb2 Qe7
Black keeps the extra pawn; White plays for time, open lines, and initiative - the classic gambit trade. White's queenside bishop takes the long diagonal. White's pawn on e4 is pinned against the king.
