If you're going to be aggressive in the beggining, do it well: instead of 7. Qd1, you should have played Qf3, so that if black castles: 7. Qf3 0-0?? 8. Qd5+!
I'm no expert on the Dutch, but I suggest not to attempt an attack on black's king until later.
Here's how the opening should be in my opinion. This is against the Classical Dutch. I'm pretty sure this isn't how white normally responds, but to me it seems like a good response.
I have been running into trouble against the Dutch Defense . I noticed there was a or is a weakness in the Defense or maybe just the player and how he uses the defense.
I don't know if it is the light squares on black side?
The weakness of a Kingside attack? maybe someone can help me...
This week i played against a player that uses the Dutch defense in a 20 min game using some ideas of the Hopton attack against the Dutch and me trying to attack... I ended up in this game... Hope someone helps me develope a stronger attack or see any weakness..
