Don't know what kkr will do when they will win toss, but if Srh wins the toss then they should bat first at any cost as putting runs on the board and then defending it is their strength. And if Srh bats first then One more good thing will be that Priyam Garg will get to bat freely without any scoreboard pressure and if he gets runs then it will good for him as well as his team.
And kkr should open the bowling with Pat Cummins surely if they want to get rid of sunrisers strong opening pair ie. David Warner and Johnny bairstrow.
