Yorkshire's bowlers underpinned their team's position at the top of Division One in the LV= County Championship by maintaining a recent stranglehold on Warwickshire in the latest meeting at Edgbaston.
Nine wickets fell to the pace attack and one to 18-year-old spinner Karl Carver as the home side were dismissed for 228, with a solitary half-century for Jeetan Patel from the number nine position.
In the last 13 months Yorkshire have twice chalked up big victories over the midlanders, but it may not be entirely straightforward this time.
In a tricky final session, Alex Lees, unbeaten with 40, and Andrew Gale (31 not out) were fully tested in taking them to 82 for two after a double strike by Chris Woakes in successive overs.
Nottinghamshire enhanced their title credentials with a ruthless display on the first day of their match at Trent Bridge as they bowled Somerset out for only 168 in just 51.2 overs, with all four seam bowlers amongst the wickets.
Notts then responded in style, closing on 208 for one, a lead of 40, after openers Phil Jaques and Steven Mullaney had put on 203 for the first wicket. Mullaney fell just before the close, for 91, but Jaques remained unbeaten on 111 at stumps.
Steven Croft and Ashwell Prince both made big centuries as Lancashire's batsmen enjoyed their best day of the season against Northamptonshire at Emirates Old Trafford.
Coming together with their side poorly placed on 33 for three in 14th over, Prince and Croft added 332 for the fourth wicket and put the bowlers to the sword in merciless fashion on the opening day of the clash.
Having batted for two minutes short of five hours, Croft was dismissed seven overs before the close for a career-best 156 but Prince remained undefeated on 161 as Lancashire ended the day on 384 for four and virtually certain to earn a maximum five batting bonus points for the first time this season.
Elsewhere in Division One, Mark Stoneman struck his third County Championship century of the season before lower order runs helped Durham to a decent total on day one of their clash against Sussex.
The left-handed opener struck 16 fours and a six in his 113 but once he fell with the total at 202 for seven, it appeared Durham would post a sub-par total after winning the toss at Chester-le-Street.
But new man John Hastings contributed a gritty 51 while Paul Coughlin and Chris Rushworth put on 47 for the last wicket to lift the total to 337 all out, with Sussex closing on 20 without loss in reply.
In Division Two, a ggressive half-centuries from Jason Roy and Hashim Amla helped Surrey into a position of strength at 325 for seven on day one against Leicestershire at the Kia Oval.
But Leicestershire fought hard in the field, led by Rob Taylor's three wickets for 52 runs with his bustling left-arm seam - and it was only an unbroken eighth wicket stand of 82 between Gary Wilson and Chris Tremlett which ensured the day's honours went to Surrey.
Glamorgan openers Jacques Rudolph and Will Bragg made hay in the west country sunshine as the match with Gloucestershire at Bristol headed in the direction of a high-scoring draw on the second day.
After the hosts had been bowled out for 391 from an overnight 308 for five, Rudolph and Bragg put together a stand of 151 in 41.3 overs on a frustratingly bland pitch before Bragg fell for 67.
Rudolph went on to end the day unbeaten on 108, having reached his second century in successive Championship games off 152 balls, with 15 fours and a six. At 209 for two, Glamorgan looked well placed to at least avoid defeat.
While former England Under-19 batsman Daniel Bell-Drummond notched a maiden County Championship century to give Kent the edge on day one of their clash with Derbyshire at Canterbury.
Bell-Drummond, 20, marked his 30th first-class appearance with a patient hundred scored in a shade over five-and-a-half hours and with only 11 boundaries as Kent posted two batting bonus points as they reached 259 for eight at stumps after winning the toss and choosing to bat first on a tinder-dry pitch.
The young right-hander fell for 101 late in the day, caught on the crease and palpably leg before, to become the last of Tony Palladino's deserved haul for five for 54 for the visitors.
