Ok, i just looked up the dutch the first time ever in my database and this is what i came up with:
Dutch Experts, please correct my variations.
(Update: Petrosianpupil improves with 8...Qf7! in the Leningrad (4...Bg7) with 8.Re1. The white rook then is missed on f1 to protect f2. Therefore i replace it with 8.b3)
@Wantobegm, thanks for the link. I left my comment (audio) on YouTube.
Well , since white is going to castle q-side anyway , this move-order (2.Nc3) is interesting as well.
