Slav Defence

edit

3...Nf6

edit

Black develops a knight to f6, and puts pressure on the e4-square. From here white has multiple good responses, although 4...Bf4 and 4...Bg5 should be avoided as black can play 4...dxc4! and retain the pawn without giving white compensation.

4.Nf3 develops the White's knight to f3, increasing control over the d4 and e5 squares. Play transposes to the main line of the slav, and it is up to black to decide how to continue with many options avaliable.

4.e3 is White's most common move. It is similar in intent to 4.Nf3, as e3 usually played at one point or another in the slav, and 5. Nf3 is the next logical development move. Play typically transposes to main line slav variations with 5.Nf3, although occasionally Nf3 is delayed in favour of other developing moves such as Qc2.

4.cxd5 is occasionally played, relieving tension in the center, and play transposes to exchange slav variations.
