First day: Nottinghamshire lead Warwickshire by 38 runs with six first-innings wickets in hand
Classy swing bowling from Ryan Sidebottom and AJ Harris destroyed Warwickshire's batting line-up in a topsyturvy day of the Division One match at Trent Bridge.
Both Nottinghamshire seamers finished with figures of four wickets for 41 runs as the visitors were floored for just 156.
Although Warwickshire quickly replied with four wickets of their own, unbeaten 50s from David Hussey and Chris Read put the hosts in front at the close on 194 for four.
Overseas star Hussey made a patient 55 while Read showed more aggression to bring up his half-century from just 49 balls with ten fours and a six, closing on 73 not out.
Despite heavy rain on Saturday, which left the wicket slightly damp, Warwickshire skipper Nick Knight chose to bat after winning the toss.
He was left to regret the decision in the third over of the match when Sidebottom found a way through his defences to bowl the former England opener for five.
Jonathan Trott edged Sidebottom through the slips twice before a 45-minute stoppage for bad light.
But the left-armer got his man at the third attempt for 31 with a late away-swinger, which was well taken by Hussey at second slip.
And Hussey claimed a better catch in Sidebottom's next over as he dived low to his left to catch an edged drive off Jim Troughton.
After lunch Alex Loudon pulled Mark Ealham straight to Graeme Swann at deep square leg for eight, before top scorer Ian Westwood's luck ran out on 49 as he pushed at another good delivery from Sidebottom and was
All- rounder Ealham quickly had Tony Frost leg before and gave the platform to Harris, who took the last four wickets in the space of seven balls. Luke Parker was caught behind by Read for 17 and Harris followed up by having Neil Carter leg before first ball.
In his next over he squared up Makhaya Ntini for another catch by Read and produced a good inswinger to remove James Anyon.
Tea was then taken but things proved no easier for the batsmen after the interval, with Jason Gallian edging to third slip and Will Smith to first as Nottinghamshire slipped to 27 for two.
Opener Darren Bicknell was tied down by South African paceman Ntini and eventually chopped on to his stumps off Dougie Brown, and Pakistan vice-captain skied a pull shot off Carter to be caught by Trott for 29.
But Hussey and Read settled home nerves with some crunching cuts and drives through the off-side in a partnership worth 119 so far, and will resume this morning looking to bat Warwickshire out of the game. n Nic Pothas and Andy Bichel frustrated Frizzell County Championship leaders Kent at the Rose Bowl as Middlesex recovered from a nightmare start to the third day.
Kent had enjoyed a fruitful morning as Hampshire lost six wickets before lunch on the third day to leave them 182 for seven.
But tail-ender Bichel topscored with 87 after joining Pothas (74) to steer the hosts to 325 all out, the wicketkeeper remaining unbeaten at the crease.
Kent, still 121 runs ahead at the start of their second innings, only managed 153 for seven at the close.
England Test batsman Robert Key top-scored with 36 but unless the Kent tail wags to good effect, the hosts may just be able to chase down a victory today. n In Division Two, Durham finally completed their first innings at the Riverside after two days interrupted by adverse weather.
The hosts made 315 thanks to Mike Hussey's 146 as David Masters took six for 74 to frustrate Durham. Halfcenturies by Darren Robinson (73) and Dinesh Mongia (77no) helped the Foxes to 217 for three by stumps.
