Still used wicket. This is the same venue where in last 10 weeks, 3 Tests, few T20s & several ODI had been played - it’s impossible to maintain the wicket squire with so many games played in short span. It takes over a week to recover from the spike marks of an ODI, even if the wicket was unused.
I saw morning session & last few overs - the way ball was spinning & new ball kicking, just wait & see the fun. In UAE, major problem for batting side is that it’s impossible on these dead slow wickets on lash large out field to do the Hetmyer job. 2.5, at max 2.75 is the expected scoring rate batting 2nd and for PAK you can take some discount on that rate.
If Kiwis do score ~275, means PAK will need to bat 100+ overs just to match 1st innings - I hope they do so, against an over rated Kiwi fielding
