Easier said than done, but let's break down what Pakistan needs to do. It's easier if Pakistan aims for small milestones for each session, rather than keep looking at psychologically imposing 252 to win.
First session tomorrow: Make about 75 runs. Do not lose Any wicket. New ball will come due in the session, so need to be careful. Yousuf will need to do a lot of talking to Umar. No unnecessary shots, be extra careful. At lunch, Pakistan 245/3
Second Session tomorrow: Make about 85 runs. Lose 2 wickets at the most (Umar, Misbah). Need to keep the scoreboard ticking, without undue risks. At Tea, Pakistan 330/5. Have Yousuf and Kamran Akmal at the crease
Third Session tomorrow: Make the required 92 runs to win. May lose 3 wickets (Yousuf, Kamran, Ajmal). Step on the gas, but Australia will be put a lot of pressure. Need one reasonable batsman (Aamer) to finish it off. Asif is pretty much a bunny, so don't let it go down to the wire. At end of play, Pakistan 422/8
*itna aasaan tou even EA Sports Cricket 2008 bhi nahin hai :D....*well I have actually scored 350 in T20 on difficulty mode 4/5! (5 being the hardest)
The first session is the key. The important thing is to not lose more than one wicket. None would be great...One of the two Yousuf or Umer Akmal has to get a big hundred
