I don't know this line, but I will give my idea on the position.
For Black, I would aim at securing the white squares in the center. Hopefully try to develop a long term attack on the K-side, using the f file. As well, try to find a good square for my White squared Bishop.
For White, I would try to get in e4 when it has a lasting advantage. Long term I would attack either the center or Q-side.
I think that general opening principles apply at such an early point.
Can someone tell me the concepts or/and basics of the Rubinstein variation of the dutch.
