Nottinghamshire moved clear at the top of Division One after comfortably batting out for a stalemate on the final day against Kent at Tunbridge Wells.
Opening batsman Samit Patel hit 76 not out, his first half-century of the season, as the visitors declared their second innings at 210-3, a lead of 102, to bring a halt to proceedings in the evening session.
Nottinghamshire, 108 behind on first innings, lost Alex Hales early in their second dig before a second-wicket stand of 105 between Patel and Mark Wagh (35) snuffed out any chance of a positive result.
Kent had earlier extended their first innings from 478-6 to 570 all out during the morning session.
Darren Stevens, on 181 overnight, missed out on a double century when he edged behind off Andre Adams for 197.
Adams, the former New Zealand seamer, finished with season's best figures of 5-106.
Nottinghamshire are now nine points above Yorkshire at the head of the table with a game in hand, while Kent's nine-point haul moves them out of the relegation zone.
Darren Stevens hit an unbeaten 181 and James Tredwell also scored a century, as Kent dominated with the bat before rain and lightning intervened against Nottinghamshire.
Responding to the visitors' first-innings total of 462 at Tunbridge Wells, Kent moved into a 16-run lead on 478-6 when play was abandoned for the day.
Tredwell complemented Stevens with an innings of 115 as the two broke the 58-year-old Nevill Ground record for a sixth-wicket partnership, eventually putting on 270.
Stevens, resuming on 80 after the second day, scorched to his fourth hundred of the County Championship season from just 105 balls.
Tredwell was more circumspect, but eventually joined his team-mate on three figures to record his third career century.
The Nottinghamshire attack simply had no answer for the pair until debutant spinner Graeme White (1-104) finally made the breakthrough when Tredwell clipped one back into the bowler's arms.
Stevens was left at the crease with Matt Coles (11 not out), as storm clouds and heavy showers curtailed the day's play.
A dogged half-century from captain Rob Key and a contrasting unbeaten 80, from 83 balls, by Darren Stevens underpinned Kent's shaky second-day reply to Nottinghamshire's 462 at a humid Tunbridge Wells.
The hosts had reached 274 for five in their first innings by the close and will go into the third day still trailing by 188 runs and requiring a further 39 to avoid following on.
Kent, batting by 12.25pm having mopped up the last two Nottinghamshire wickets for an additional 69 runs, made a dismal start to their pursuit by losing Joe Denly to the first ball but fought hard thereafter on a dry, slow pitch to take two batting bonus points by stumps.
Key and Geraint Jones (37) added 53 either side of the lunch break before Jones nicked a drive to Hussey off the bowling of Andre Adams. Then, moments before tea, Martin van Jaarsveld (44) edged an attempted cut off Adams to be caught behind by Read.
Two overs after the resumption Adams rushed one through Sam Northeast's back foot defensive push to send him packing for 12 and then, having agonised for over three hours for his 56 from 156 balls, Key fell to make it 176 for five.
Stevens, Kent's leading run-scorer with over 600 championship runs to his name so far this term, steadied the ship with a fluent 62-ball half-century which included 11 fours.
It was his sixth time past 50 in four-day cricket this summer and by the close the former Leicestershire man had taken his boundary count on to 15, having added 98 runs for the sixth wicket with James Tredwell (35 not out).
Division One leaders Nottinghamshire battled back with the bat after a disastrous afternoon session against Kent at Tunbridge Wells.
The visitors slumped from 154 for one to 266 for six in between lunch and tea, Alex Hales one of the wickets to fall having made 95.
The right-hander helped put on 43 for the first wicket - Nottinghamshire's best opening stand in their four-day campaign campaign to date - before sharing a 111-run stand with Mark Wagh, who made 44 from 94 balls.
After Hales was caught and bowled by Malinga Bandara just five short of his century, while the Sri Lankan leg spinner also removed Australian David Hussey, who only landed in the UK on Wednesday, for 52.
However Notts skipper Chris Read led a fightback after the tea interval, hitting five fours and a six to reach the close on 72 not out.
The wicketkeeper-batsman added 69 with Andre Adams (35) to help his side close on 393 for eight. Meanwhile, Kent suffered a late blow when seamer Amjad Khan limped off for treatment to a leg injury in the final over.
