The main line of the Dutch Variation of the Slav Defense is 9. Qe2 and it’s covered in our Line 108. Various options for White on 9th move can be found here.
The idea of 9. Nh4 is clear – to destroy Black’s light-squared Bishop. Black has the choice between leaving the Bishop on f5 with 9… O-O, offering the exchange on g6 with 9… Bg6, or trying to escape from the Knight with 9… Bg4. The last one typically leads to preferable positions for White, but the other two moves are regarded as equally good and solid.
[Diagram: Black to Move] Black has sacrificed a piece and has a promising attack, though there’s only one path to a clear edge. What is the best continuation for him?
