Actually, they are playing exactly the way one should play in such condition - if couple of wicket goes down so it be, but scores are also piling up. I give a classic example - at Cape Town, on a difficult wicket, PAK got a slim lead of 12 & ended the day 2 or 3 down for 100 or so - that's say effectively 110/3. Next morning, Misbah & Azhar (Or Asad) batted for 23 overs for 35 or so & at one point. SAF didn't get wicket, but score board stayed there - just before lunch, SAF knocked few in quick time & after lunch, PAK was all out for 170 or so - SAF won that Test by 4 wickets with their top 6 gone.
Low scoring matches are there to be bold & a bit lucky.
