Monte Carlo Variation

[edit | edit source]

By playing 4.c4, White gains some space at the expense of not being able to defend the d-pawn. This move also tries to destabilize the d5 pawn, and open up a line for the bishop.

Common responses by Black include Nf6 which guards the pawn and develops a knight, c6 also guarding the pawn, just taking the c4 pawn with dxc4, or Bb4+ to gain a tempo on the white king and develop a bishop.
