Looks like, Cook'll give PAK to chase 320 in about 80 overs, or may be 85 overs, so that he has 5 overs with 2nd ball.
Good Test wicket, but they just kept slightly more moisture which actually is bonding the surface even on Day 4. But, without that moisture, ENG won't have been 155/5 on Day 1.
Teams that are dominant with 4 bowler Strategy (AUS, IND), in such situation, actually takes the game away on 1st innings. PAK playing with 4 Bowler strategy + MoHa; therefore ..... you know.
If both sides go to Oval 1-1, which is most likely; I would say PAK would do smart picking Imran & Wahab for MoHa & Sohail. The amount of work load that Aamir & Rahat has gone so far (not to mention Yasir - he is struggling here, because Misbah has over used him with newish ball & on Day 1/2, Poms have got a better look at him at his vulnerable time), I won't be surprised if one of then breaks down at Oval for another 50 overs load.
In that case, 11 batsmen won't save PAK.
