I think, PAK will need around 170 as least, so another 170 tomorrow should win this game. Theoretically, 180 overs still available, but I guess we'll get around 170. Best for PAK is to get all-out for 250 or so, which will allow then to win 3-0 & avoid point deduction. If Misbah is allowed to declare, he'll bat till 1 hour into day 5 & set 300 in 70 overs.
Azhar is the key - if he can get a hundred, last 6 wickets can put another 200.
