Moves: 1. d4 d5 2. c4 c6 3. Nc3 dxc4 4. e3

4.e3

edit

This is considered to be the best move as white:

  • Keeps the e4-square free for the c3-knight to retreat to incase of a b5-b4 advance from black.
  • Gains control of the center with pawns on e3 and d4.
  • Prepares to capture the c4 pawn with Bxc4.

Black should prevent the capture of the c-pawn with 4...b5. This also sets a deep trap for white. This usually leads to very complicated variations on the queenside where white attempts to undermine Black's defence of the c-pawn with moves like a4. If white can successfully recapture the pawn, white is better.
