As EMSC suggests, Pole position is on the left.
This is the 'outside' part of the track, which tends to be cleaner - although the dirty side of the grid is much better here than at many other circuits. So, with traction being roughly equal, Shanghai's Pole-slot only gives its driver the advantage of a few yards to the first braking point; and of course, the advantage in the braking zones is with the driver on the inside, if close enough.
I expect Schumacher to launch an aggressive attack immediately - and I still have lingering question marks over Rosberg's defending abilities, which seem to vary between very good to very poor indeed. He often seems easily intimidated into submission, and usually backs out of anything approaching 50/50s. One wonders; will he put his defensive head on? On the other hand, Schumacher only has one, ruthlessly aggressive head (it's wonky shape suggests years of use as a battering-ram), so if Rosberg does put up a fight, I expect an intense scrap until either Rosberg draws out a lead or Schumacher barges past with a move designed to frighten if necessary.
If Rosberg allows anyone to get alongside, he'll lose the corner; but he may have chance to return the favour in turn 2 - if he's still on track and does not give up…
