So do we take this partnership and Root's innings as evidence that Bazball is more adaptable than it was given credit for or vindication for everyone who said Root needs to bat how he normally does? I will go for a bit of both. Bazball with a dose of common sense when needed the way forward - perhaps Bazball Lite.

Ben Foakes is still being tested here, as Jadeja gets another to skittle through very low outside off stump.
Concentrate before tea, lads.
Should've listened to the keeper.
Missing leg stump, and India are out of reviews.
Now then!
This feels like lbw review number 34 of the day. Jadeja likes it, the keeper Jurel isn't sure - suggesting it's missing leg.
Rohit Sharma sends it upstairs with seconds to spare.
Oh, Ben Foakes. You lucky, lucky man.
Ashwin gets one to keep very low, almost identical to Stokes' dismissal and Foakes misses - but it's a fraction wide of off stump.
A couple of balls later, one rears up off a length and pins Joe Root on the glove. Yeah, it's still not easy.
As we said earlier, Ranchi is the home of MS Dhoni. He's still a hero to the home crowd.
And again.
Too wide from Jadeja and Root cuts fine for four.
Jadeja is seething, swishing his floppy hat around in frustration because that was a gift, after his endless overs of consistency.

This is clearly a new-ball pitch. Once the ball gets soft it’s flat.
Can we also give Joe Root's back-foot punch for four a knighthood? It's also a thing of beauty.

Joe Root's defence has been immaculate all day. Thou shalt not pass.

It is funny how you get a partnership going, the wicket flattens out and it looks a bit easier. After that frenetic first session, Joe Root has played very nicely - ably supported by Ben Foakes.
They have put the risky shots away and just knocked it around.
Root refuses to give in to Jadeja, who gets through another maiden.
He's not only fulfilling the role of frontline spinner, number five batter and gun fielder, but he's clearly Chief Ball Shiner too. He has bright red stain right down the front of his shirt.

Maybe unfair of me to be cynical but do you think India resting Bumrah has allowed Root to relax more earlier in his innings? It’s great to see him playing so well but I can’t help but wonder if that’s a factor.

Ashwin works through all his variations in pace but Root or Foakes aren't tempted yet. If they can make it through the entire session unscathed, it will be heck of an effort.
Joe Root's half-century is the fourth-slowest in the Bazball era. These two currently at the crease hold four of the five in the list below:
Lovely! Joe Root drives through the covers for four as Kuldeep loops one up a little too full.
One keeps very low a couple of balls later but he jams his bat down in time. The pitch just keeping us all on our toes...
Root 53, Foakes 25
Ashwin's wicket earlier was his 100th in Tests against England. Not bad.
Just the single from Kuldeep's latest over.
We've had two very intriguing, gripping sessions in two completely contrasting styles. And that's wat we love about it!
Joe Root's shot selection has been flawless so far. He's only using the sweep to balls that are away from the stumps to minimise the risk, but it's still not looking like an easy shot to play.
