4. cxd5 · Exchange variation

[edit | edit source]

After this move, the tension in the center is relieved, often allowing Black equality. Because of this, this variation often ends in a draw.

Black's only decent move is to complete the exchange of pawns with 4...cxd5. After the exchange, Black will find it difficult to win unless White is overly ambitious.

The most draw-ish line of them all is the symmetrical line. Black keeps copying White and both sides exchange minor pieces: 4...cxd5 5. Nc3 Nc6 6. Bf4 Bf5 7. e3 e6 8. Bd3 Bxd3 9. Qxd3 Bd6 10. Bxd6 Qxd6 11. O-O O-O =. Most players agree to a draw in this or any of the following positions.
