English Opening · A13
Agincourt Defense, after 2. Nf3, through 2. Nf3
1. c4 e6 2. Nf3
c4 fights for d5 without committing the centre pawns: White often fianchettoes and plays a reversed Sicilian with an extra tempo.
The first 3 moves, explained
- 1. c4 Fights for d5 from the flank - contesting the centre without committing a centre pawn. Theory calls this the English Opening.
- 1... e6 Supports the centre, adding control of d5. Theory calls this the Agincourt Defense.
- 2. Nf3 Develops the knight to f3, eyeing d4 and e5.
