Riyad and Nasir should try to bat till lunch and possibly get close to the WI total.
If a wicket falls in the first session, Gazi and the other batsman should bat with controlled aggression to try and reduce the deficit instead of getting bundled out.
If the current pair survives till lunch, just keep batting and try to get a lead close to 80 and keep batting till Tea and aim for personal milestone.
After tea, ATTACK! Declare and put WI to bat before the EOD.
