Accelerated London, Steinitz CountergambitEdit
Black responds by immediately striking in the center with c5. White's most common reply is 3. e3 defending the d4-pawn and building a solid center. Accepting the offered pawn with 3. dxc5 is possible, but this is much less common as it doubles White's pawns on the c-file and abandons White's plan to construct a closed position for the London.
