England produced a dominant display on the first day of the second Natwest Test match in Leeds to leave Pakistan in big trouble.
After Sarfraz Ahmed chose to bat under initially sunny skies at Headingley, England's seamers revelled in humid conditions to bowl Pakistan out for 174.
By stumps, despite the late departure of Alastair Cook, the hosts were well placed on 106-2 as they seek to level the series at 1-1.
Stuart Broad and James Anderson shrugged off recent criticism by taking three wickets apiece while the returning Chris Woakes claimed three victims himself - including the dangerous Asad Shafiq.
Shadab Khan (56) responded, after the loss of three wickets for one run, with spirited resistance to help Pakistan more than double their total from 79-7, but the visitors still looked woefully short when Khan was the last man out, dismissed by debutant Sam Curran.
It was a first Test wicket for the Surrey all-rounder and he was immediately mobbed by his teammates who looked in good spirits throughout the day and turned in a much-improved fielding performance.
Pakistan lost their first wicket without a run on the board, Imam-ul-Haq edging the last ball of Broad's first over high to Joe Root at third slip.
The tourists took 27 balls to open their account, Azhar Ali eventually scrambling a single off Anderson before being pinned LBW by Broad in the 10th over.
Haris Sohail and Shafiq both went before lunch, too. Sohail became Woakes' first victim, edging one angled across him to second slip, and then a juggling Cook held on at first when Shafiq was undone by a beauty from the same bowler.
Anderson, below his best in the morning, found much better rhythm in the afternoon and bowled Sarfraz off his pads as the Pakistan captain aimed to leg.
Broad then struck again as debutant Usman Salahuddin was LBW pushing forward before Anderson wrapped Faheem Ashraf in front, too.
Shadab and Mohammad Amir were in counter-attack mode, however, and took the total into three figures before the left-hander flailed a catch behind off Anderson.
Hasan joined Shadab for another handy stand, 43 from just 31 balls - the number 10 climbing into three off-side fours in the eighth and last over of Anderson's spell either side of lunch.
Shadab's was the stand out innings, though, and he completed his 48-ball half-century with a memorable pull in front of square off Woakes.
Prior to that, Woakes had held a sharp return catch to see off Hasan, before Curran wrapped up the innings with the help of Keaton Jennings in the deep.
Cook and Jennings provided an initial platform, but little more, with only England's second half-century opening stand since the penultimate Test of last summer - at this same venue.
Jennings, first of the 12 opening partners for Cook since 2012 to be given a second opportunity in the role, hinted he may be able to make a success of it until he fell to the last ball before mid-evening drinks.
The impressive Ashraf located Jennings' outside edge to end his stay on 29 - just reward for a probing spell - before Cook and Root took over with a promising stand.
The pair were untroubled until Cook gloved behind on 46, requiring nightwatcham Dom Bess to see England through to the close at 106-2.
A strong response from England after last week's crushing defeat at Lord's and it was Pakistan who left the field with much to ponder.
