A57
Benko Gambit Declined
6 named lines in this family, ECO A57. Every one of them opens 1. d4 Nf6 2. c4 c5, 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. d4 Nf6 2. c4 c5
- 1. d4 Stakes a claim in the centre, controlling e5, and frees the bishop and queen.
- 1... Nf6 Develops the knight to f6, eyeing d5 and e4.
- 2. c4 Fights for d5 from the flank - contesting the centre without committing a centre pawn.
- 2... c5 Challenges the pawn on d4 - the central tension has to resolve. Theory calls this the Benoni Defense.
