Harry Brook moved England steadily into series-winning pole position by making sure Pakistan will have to make the biggest total of the game in the fourth innings if they are to win.
That is a highly unlikely outcome on a pitch that has already offered far more to the bowlers than the last especially for bespectacled spin twins Jack Leach and Abrar Ahmed who both celebrated milestones on day two.
For Leach, his 4-98 helped make him the 13th left arm spinner to take more than 100 Test wickets for England, while Abrar duly grabbed 10 wickets in the match after taking three of the five to fall in the second innings by the close of day two.
