Buddy, agree most of these were decent pitches to bat on. Was just weighing on the fact that Virat's runs weren't hailed purely because of batting under scoreboard pressure, it was the quality of batsmanship - because it isn't just defending a swinging ball with soft hands, it is also about your defence vs spin when trying to save a match, your temperament in seeing off a plan by the opposition, dominating when the time is right and converting 50s into match-winning hundreds (re: Root) - plenty of all this was there. Ball wasn't just pinging the middle of the bat for every batsman, and there was some good quality bowling on display. And as you said, the innings were about pressure, which is a by-product of good bowling which again is possible on pitches that give something to the bowlers - not the Chennai decks.
And about the 10X tougher bowling England had to face, I am sorry dude but that is just unfair. On pitches other than in Mumbai, there was hardly any spin in the first innings of the series. This wasn't a Nagpur'15 case. And England batsmen simply failed to get 100's, that shows poorly on the batsmen - blaming it on the quality of bowling won't help.
Other apart from Virat were struggling in that Mumbai inning, but Virat just looked set. And the Rajkot 260-3 case for England I thought was due to many factors - Ashwin bowling outside leg stump, no close in fielders, England playing well and the case of Unlucky Umesh. Ball was spinning well throughout the final day. Never judge a pitch by the scorecard.
