Chris Woakes finished with 6-49 as Warwickshire made it two wins from two with an 88-run triumph over Worcestershire.
Chopra posts first-class best of 228 as visitors win at New Road
Warwickshire made it two wins from two at the start of the new LV County Championship season with an 88-run triumph over Worcestershire.
Set 278 in 75 overs, the hosts were bowled out for 199 with time to spare at New Road thanks to another fine display from Chris Woakes.
The talented seamer furthered his England claims by knocking over the top three in the order on his way to figures of 6-49, meaning he has now taken 16 first-class wickets already this season.
However it was Ant Botha who claimed the crucial scalp of Alexei Kervezee, who had threatened the Bears' victory push with a fine 65 from 91 balls.
Gareth Andrew (26) supported Kervezee in a stand of 66, but Woakes then returned to claim three more victims in the space of 14 deliveries.
Warwickshire themselves had suffered a batting collapse in the morning session, having resumed on the final day of the Division One fixture on 411-3.
They lost five wickets in a hurry, Varun Chopra amongst them for a career-best 228, his second double ton already in 2011 - but Botha's unbeaten 28 allowed skipper Jim Troughton to declare at 461-8.
Warwickshire opener Varun Chopra batted throughout day three to score his second double century in a row as Worcestershire's bowlers were made to toil at a sun-kissed New Road.
Chopra, on 57 overnight, helped the Bears advance their first innings from 76-0 to 411-3 by the close, a lead of 237.
The former England Under 19 captain, who made 210 in the win over Somerset last week, hit 32 fours and a six to finish on 223 not out from 352 balls - in the process becoming the first batsman in Warwickshire history to score double tons in back-to-back Championship fixtures.
He lost Ian Westwood and William Porterfield in the morning session as Warwickshire went to lunch at 157-2, still 17 behind.
But Mohammad Yousuf (81) joined Chopra in a 185-run partnership for the third wicket and, when Yousuf became a second victim for Pears seamer Gareth Andrew (2-91) after tea, Warwickshire skipper Jim Troughton (42no) ensured the runs continued to flow.
Half-centuries from Moeen Ali and Matt Pardoe put Worcestershire in control against Warwickshire at New Road.
Moeen hit 92 against his former county, while rookie batsman Pardoe scored 54 in only the second first-class appearance of his career. Their contributions helped lift Worcestershire to 375 all out off 106.2 overs in reply to the visitors' 201.
Paceman Boyd Rankin took 5-57 for Warwickshire before the visitors closed on 76-0, just 98 in arrears.
Moeen, who this week agreed a new contract to extend his time at New Road until the end of the 2013 season, was just eight runs short of the sixth first-class century of his career when he turned spinner Ant Botha to Rikki Clarke at slip.
Botha (3-39) struck again two balls later to remove Gareth Andrew, before dismissing Ben Cox shortly before tea when the home side were 347-7 off 101 overs.
Stourbridge-born left-hander Pardoe, who made his debut in Worcestershire's opening Championship match of the season, registered his maiden first-class half-century in the second over after the break before falling to Rankin after hitting eight fours in a 142-ball knock.
Warwickshire looked in deep trouble but an unbeaten stand between Varun Chopra (57) and Ian Westwood (19) got them back into the contest at the end of day two.
Worcestershire paceman Damien Wright claimed 5-62 to help dismiss Warwickshire for 201 on day one of their County Championship Division One match at New Road.
The Australian was ably assisted by Gareth Andrew (3-45) to remove the visitors, who scored a record innings-and-382-run win at Taunton last week, in 59 overs.
Warwickshire were 85-4 by lunch, with captain Jim Troughton (33) sharing stands with Varun Chopra (33) and Rikki Clarke (34) before Wright dived well to catch him off the bowling of Alan Wright.
Having earlier been put down, Chris Woakes went on to top score with 47 not out from 52 balls, putting on 42 with Boyd Rankin before he became Wright's fifth scalp.
At the close Worcestershire's reply stood at 155-2 off 37 overs following a century stand between openers James Cameron (56) and Daryl Mitchell (43).
