Indeed, also, watch out turn 4, thats single file, otherwise you catch the grass and hit the wall. Shicane is also single file, main overtaking points are the straights, if you can get a good run out of the fast shicane and hairpin and the hairpin and slow shicane under braking.
Turns 3 and 4 are very difficult to overtake, as whatever you do, you will almost certainly be offline for the next corner. Running wide is also common on these corners, so going round the outside is competely out and trying to throw one up the inside is suicidal, you'll both end up in the wall because all the overtakee has to do is hold his line and theres no way through.
Patience is the key, let off when following through fast corners, don't get too close and make your move when its safe.
