Adam Hollioake brightened a largely uneventful day here with a whirlwind unbeaten 87 in the final session as Surrey reached 237 for 4 in their first innings in reply to Warwickshire's total of 413 all out.
The Surrey captain scored most of an unbroken fifth-wicket stand worth 116 with Alec Stewart which recaptured the initiative for the hosts after three wickets had fallen for only eight runs just after tea.
Hollioake bludgeoned 13 fours and a massive straight six off the England slow left-armer Ashley Giles while Stewart, who ended the day on 29 not out, was happy to play second fiddle.
But Hollioake also enjoyed two large slices of luck – at 49 when Tony Frost fumbled a gilt-edged stumping chance off Giles and at 62 when Neil Smith dropped him at mid-off off Dougie Brown.
After a sharp downpour had delayed the start of play by an hour and a half, Mark Wagh completed his 14th first-class century and steered the visitors to two batting points as he added 70 for the last wicket with No 11 Alan Richardson.
Wagh, 91 not out overnight, looked likely to be stranded short of three figures when Smith was caught behind by Stewart off the medium-pacer Azhar Mahmood for 20. But Richardson, belying his tail-end status, batted sensibly and confidently to enable Wagh to achieve his personal milestone.
