Eoin Morgan scored his maiden Test hundred as England rebounded from quick blows early on to move into a strong position against Pakistan on Thursday, the first day of the first Test.
Pakistan had reduced England to 118 for 4 shortly after lunch before Paul Collingwood and former Ireland left-hander Morgan joined hands to resurrect a revival.
England were 295 for 4 after 80 overs, when the second new ball was due.
In a series where the Decision Review System (DRS) was being used in England for the first time, Pakistan wasted both their two permitted unsuccessful challenges on appeals by Mohammad Asif for lbw and caught behind against Kevin Pietersen on one and five.
But Asif then bowled Pietersen, leaving a gap between bat and pad, off the inside edge.
England's other South Africa-born batsman, Jonathan Trott, had added just three to his lunchtime 35 when he padded up to an inswinger from Aamer.
Trott, succcessful with a previous referral, asked for New Zealand umpire Tony Hill's lbw verdict to be reviewed.
But replays suggested the ball was clipping the top of the stumps and Trott was out, with England 118 for four.
And there was a fresh flashpoint when wicketkeeper Kamran Akmal appealed for a catch against Morgan, on five, off the bowling of left-arm fast bowler Mohammad Aamer.
But even before the third umpire ruled in Morgan's favour, crowd jeers were ringing round Trent Bridge as replays on the giant screen showed the ball had clearly bounced into Kamran Akmal's gloves. It took Collingwood 30 balls to score his first four but then two came in as many Umar Gul deliveries, courtesy of a couple of square cuts.
Morgan then cover-drove and glanced Shoaib Malik for fours. Both batsmen cashed in against Pakistan's slow bowlers and some poor fielding. Wicketkeeper Akmal missed a stumping chance against Paul Collingwood besides dropping a catch earlier. He failed to collect the ball on a few occasions.
