B01
Scandinavian Defense
45 named lines in this family, ECO B01. Every one of them opens 1. e4 d5, 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 d5
- 1. e4 Stakes a claim in the centre, controlling d5, and frees the bishop and queen.
- 1... d5 Stakes a claim in the centre, controlling e4, and frees the bishop and queen. Theory calls this the Scandinavian Defense.
Main line, after 2. b3B01
1. e4 d5 2. b3
- 2. b3 Prepares the fianchetto: the bishop will take the long diagonal via b2.
Zilbermints GambitB01
1. e4 d5 2. b4
- 2. b4 Opens the c1-a3 diagonal for the bishop. The pawn is genuinely on offer - this is the Zilbermints Gambit: development and initiative over material.
Blackburne-Kloosterboer GambitB01
1. e4 d5 2. exd5 c6
White is up material out of the opening - Black is banking on activity to show for it. White has doubled pawns on the d-file.
- 2. exd5 Takes the pawn on d5, toward the centre.
- 2... c6 Challenges the pawn on d5 - the central tension has to resolve. Theory calls this the Blackburne-Kloosterboer Gambit.
