1. d4 d5 2. Kd2 leads to sharp tactical play.
Aggressive d4 opennings
Sort:
If you are not particularly interested in getting an opening advantage then the Veresov(1.d4 d5 2.Nc3 Nf6 3.Bb5) can lead to interesting games if white chooses the right variations. The Saemish variation 4.a3 against the nimzoindian can lead to sharp kingside attacks. There are many sharp possibilities inside the rich 1.d4 world, maybe you can describe your actual repertoire here?
