An early pawn trade leaves the c-file as White's avenue and the d-file as Black's - both sides get real winning chances down their own file. White has doubled pawns on the d-file.
The first 4 moves, explained
- 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... e6 Supports the centre, adding control of d5.
