Nottinghamshire continued to set the pace on the second day of their LV= County Championship match against Somerset at Trent Bridge.
The home side forged a first innings advantage of 293 after being bowled out for 461 in 102.2 overs. Phil Jaques fell early in the day for 113, having added just two to his overnight score but a stand of 161 between Samit Patel and Riki Wessels took the game away from the visitors.
Patel eventually fell for 94, the third time this season he has fallen in the 90s, with Wessels making 76. Craig Overton returned the best figures with the ball, ending with 4-102.
Batting again, Somerset reached 106 for three by stumps, still trailing by 187 runs, with Chris Jones undefeated on 59.
Somerset responded well to their first day mauling by having the better of a rain-truncated morning session, picking up four wickets.
Jaques only added a couple of runs to his overnight score before punching to point for 113 and Ajmal Shahzad, the nightwatchman, drove straight to cover.
James Taylor was sent on his way by a leg-side strangle after being adjudged to have tickled Peter Trego into the gloves of Craig Kieswetter.

Alex Hales was undone by a combination of the impetuosity of youth and the tactical nous of Marcus Trescothick. The Somerset skipper employed young tyro Jamie Overton to bowl a short-pitched line from around the stumps, with short-leg, leg-slip and long-leg in place.
The England Twenty20 batsman could not resist the challenge but only succeeded in top-hooking the ball down to Craig Overton, just a couple of yards inside the boundary.
Wessels reached his fifth half-century in the last eight days, getting there from just 72 balls with nine fours and a six. The 28-year-old is the leading six-hitter in first-class cricket and he then put George Dockrell over the ropes for another maximum, his 20th of the championship campaign.
Patel reached his own fifty from 69 balls and soon after went past Middlesex's Chris Rogers to become the leading run scorer in Division One.
Already with more batting points than any other side in the country, Nottinghamshire gathered another full compliment by reaching 400 but Somerset struck back in style, concluding the innings with five wickets in 5.5 overs, for the addition of just 34 more runs.
Wessels lofted to mid-off, Patel feathered behind and then Craig Overton removed Chris Read and Andre Adams in the same over.
Peter Siddle's rapid departure gave Somerset renewed optimism but much of that evaporated in the final session after Trescothick had edged to Patel for the second time in the match and Nick Compton and Alviro Petersen had followed cheaply.

Chris Jones reached a fifty from 80 balls but will need some support on the third day if Somerset are to have any chance of being able to maintain their unbeaten record.
Somerset batsman George Dockrell is remaining positive despite Notts' progress.
"I thought we fought back pretty hard this morning and although they batted well, we took the last few wickets as cheaply as we could have hoped and kept the lead to a lot less than it looked like being," he said.
"The pitch is pretty good to bat on but we came back today and were far more disciplined and put the ball in good areas. Craig Overton bowled extremely well and deserved his wickets.
"We've just got to try and bat as long as we can tomorrow, take our time, see where we get to and take it from there."
Nottinghamshire's Taylor hailed the impact of Wessels and Patel's stand.
"Getting runs when you are in good form is the key and that's what they're doing at the moment. You've really got to make the most of it when you can," he said.
"They've set us up, put us in a great position and now it's down to the bowlers and fielders to restrict them to something we can chase down.
"We've had a good start with the ball, Harry Gurney has been exceptional. We've got them three down on a pretty good deck so hopefully we can push on for the win tomorrow."
