Excellent first day for England on a pitch that is admittedly somewhat easier to bat on than those encountered in Bangladesh. As people have alluded to earlier in this thread, Shami and Yadav were impressive first up and Hameed and Cook did well, albeit with a huge slice of fortune in Cook's case, to survive the first 10 overs. Cook looked more like the nervy 19 year-old, groping at several deliveries in that opening burst, Hameed the more assured, organised and calming influence. Cook will be disappointed with his dismissal just when he seemed to be finding his feet.
Hameed was impressive in making his 31, I've not seen a lot of him and while reluctant to get carried away by one innings, he does appear to have the temperament and technique to make a real case for this position on a permanent basis, but of course this is still very early days.
Ben Duckett I think is going to have real problems with Ashwin, so concerned about getting trapped LBW with the one that goes on, he is exposing his stumps and his vulnerability to sticking off with any delivery that straightens on him.
Joe Root looked an absolute class above. Moeen was also more disciplined than I've ever seen him, while also playing with calculated risks when allowed. Root just didn't miss an opportunity to score, his piercing of the field to several full tosses was a lesson to anyone not to overhit the ball even when the ball is there to be slapped. Everything about his play was to be admired, he was solid in defence, forward and back incisively, rotation of the strike was impressive never allowing the bowler to settle, and he looked busy and kept the board ticking. He was a real joy to watch.
As for the Indian attack, good effort from Shami and Yada first up and a couple of impressive spells later in the day when it started reversing, Yadav unfortunate not to trap Root LBW in the 90's. Shami was hampered throughout the afternoon/evening session with a dodgy hamstring, but carried on manfully. There wasn't a lot of turn around which negated Ashwin and Jadeja to a degree, and Mishra threw in too many four-balls.
