This line seems to be Mardell:s speciality. Three game in the Swedish elite so far.
He has two draws and one win.
But I am not an expert on this line since I prefere e5 line.

Here is an intresting game in 9 0-0-0 d5.
Since i dont play Nxc3 variation I havent analysed this game.
I think that Qf2 is a novelty.
