After a day of fluctuating fortunes Notts will require a further 75 runs with three wickets remaining on the last day of their Second Eleven Championship match at Headingley.
Continuing on 131-9, Sam Kelsall and Andrew Carter added a further 10 runs before Kelsall was bowled by Hannon-Dalby, who finished with 6-49, for 36.
In less humid conditions than on the first day, early inroads were made in Yorkshire's reply, Alex Hales taking two catches at slip from the bowling of Fletcher and Adams .
The home side recovered from 17-2 before losing two wickets at 78. A stand of 109 between Simon Guy 72 and Lee Hodgson 38 seemed to have taken the game from Notts. Andre Adams and Paul Franks then initiated a collapse as Yorkshire tumbled from 187-4 to 203 all out.

Mark Footitt claimed two wickets in 10 balls to finish with 3-13, Paul Franks took 2-35 and Andre Adams 2-64.
For the second time in the match Sam Wood hit the stumps direct to run out David Wainwright.
Needing 218 to win, Notts lost Matt Wood to the third ball of the innings to Hannon-Dalby who at the close has match figures so far of 9-76.
It was however left arm spinner David Wainwright bowling into the rough outside the off stump who was to cause Notts the most discomfort. Hales and Franks had put Notts on the road to recovery before Franks was out for 28. The innings then went into decline when Akhil Patel was out with the score on 80.
Three further wickets fell quickly but Alex Hales was batting well and reached 50 from 75 balls .
Yorkshire with a further 4 wickets to get were allowed to claim the extra half hour and Hales could only play a ball that bounced on him back to bowler Hannon-Dalby having scored 57 including 5 fours and a six.
Sam Wood (24) and Scott Elstone (3) batted sensibly through to the close.
