Virat is still going at umpire Dharmasena. Dharmasena has got to keep his cool here - and not think he owes India one for that.

Jadeja rounds off the over with another one that spins sharply, and Cook does well to get his bat down and smother it. It's getting a little heated out there, with Kohli and square leg questioning Dharmasena about that lbw decision.

Kohli has dropped the ball to the ground and had a word with Dharmasena.

Ooft. Cook is not out by less than a centimeter, the ball just brushing Cook's leg stump. The tiniest of margins has saved Cook there.

The crowd is very excited.

Hey up. Jadeja reckons he's got Cook lbw, and he's persuaded Kohli to go upstairs.

England can't get these runs. Teams that get themselves into this position in the field, they attack too late, they get desperate. If I was to give Kohli some advice, it would be to pretend that this is the last hour tomorrow.

Shot! People say Cook isn't a pretty batsman. He cuts Ashwin gloriously through point, leaving two fielders glaring at each other over who should have been cutting that off. Ashwin tosses it up and its Hameed who bites this time, driving Ashwin over the top for another boundary. This is excellent from England; a measured attack on Ashwin is a smart move.

Last hour of play and Kohli has got his fielders all up in Cook's grill. There's five around the bat, and Cook gets a horrible one that rears up and bounces over the stumps. He responds perfectly, scything through the covers to notch up his third boundary.

This is terrific to watch. It's concentration of the highest order.

Here we go. Ashwin's back. Hameed drives through the covers for a couple, breaking the deadlock, and the rest of the over is too full from Ashwin. It's relatively easy for Hameed to defend. That'll be drinks.

JonesyJones: Cook & Hameed going slower than Boycott & Tavare in super slow motion. Keep it up boys.

Jadeja gets one to turn, then the next one stays straight, and Cook has the tiniest of fiddles outside off stump. It goes on past the outside edge, to ooh's and aah's from the fielders. Cook get his pad well outside the line for the next few deliveries, while Joe Root keeps his head down in the dressing room.

At the moment, there will be more fretting in the India dressing room than the England one. It's clearly possibly to bat out there, but whether you can play scintillating strokes is a different matter.

Virat Kohli is thudding his hands together at slip, encouraging his fielders. It's gone quiet in Vizag, the crowd keeping a watchful eye on everything. Cook's having none of it. He momentarily considers pulling a short ball from Shami, but then he remembers what he's there for, and he sticks to ignoring it.

Brian Smith: My project manager's Australian. We can engineer an innings together at 3 & 4.

Ben Thomas: Was opposite Harold Bishop at the checkout in Aldi a few months ago, surely I'm a shoo-in to open?

It's keeping so low that Cook is almost bent over double as he defends. He sneaks a run, leaving Hameed to face Jadeja, and the close catchers crank up the noise. There are four around the bat, but Hameed is unruffled, showing the full face to everything that comes his way.

It took England 37.1 overs to reach 50. Their slowest is 38.5 overs - in the second innings against Sri Lanka at The Oval in 1998.
