I'm also going for lunch, so here's Matt Henry to take you through the interval and the afternoon session.

The defining moment of the session and maybe the match?

Harry Brook should have been out for 19. Instead he's headed into lunch unbeaten on 38 (30).

It sounded like bat on ball with how hard it hit Akash Deep's shin.

He will have to get that iced over lunch.

Bowler Akash Deep wears one on the shin. That looked painful.

But he bowls the remaining four deliveries to take us through to lunch.

From 50-1 overnight, England have advanced to 164-3 in pursuit of 374.

Gilbert Jessop's record for the fastest England hundred, 76 balls, came in the record highest run chase on this ground, 263 v Australia in 1902. Just saying.

Akash Deep will prefer to bowl at Joe Root with how Harry Brook has taken him on.

Akash Deep very tired there. Long, long overs in the field.

Joe Root and Harry Brook exchange singles. Then, a wide from Akash Deep races away to the rope. It's been a horrible few minutes for India.

As a matter of record, Brook was on 19 (21) before Mohammed Siraj's error. He's on 36 (28) now.

The bowlers union is hurting right now. It has gone from zero to a hundred.

The word draw doesn't enter England's thinking. There is different ways you could go about this, but in Harry Brook's mind, if he wants to make a dent in that target, he decides.

My, oh my.

Two balls after being reprieved on the boundary, Harry Brook is swinging for the hills again. He picks up four through cover, runs two, and adds up another four wide of the slips.

After every shot, the camera pans to Mohammed Siraj, who has one hand over the bottom of his face. He looks ashen.

16 off the over.

Mohammed Siraj didn't set himself there. Poor Prasidh Krishna was celebrating thinking he had it.

Mohammed Siraj cannot believe what he has done.

Harry Brook has got away with one there.

He picks out Mohammed Siraj in the deep but as he's settling himself under the ball, his backfoot touches the rope. It's six and not a wicket.

Prasidh Krishna aborts his celebration. Siraj looks mortified and he's not getting much sympathy from the fans behind.

11 runs chipped off that 374 target by Harry Brook - a productive over for England.

Mohammed Siraj is coming back down the stairs after his break. Dark clouds are beginning to swell on the horizon.

Harry Brook is coming on the charge here.

Brook is trying to make Akash Deep make some errors.

A little counter punch from Harry Brook. You can see Akash Deep lining up that length consistently.

In Brook's mind he has changed the tone.

Eng 136-3published at 33.4 overs

33.4 overs

Target 374

Harry Brook was building up to that. He wafted at the first ball, tried to dance down to the second, pounded the third for four...

And then he's charged Akash Deep! Over extra cover for SIX!

You can't bowl there, and Joe Root drives Prasidh Krishna again through the covers.

Five good balls from Prasidh Krishna but his final delivery of the over is too wide and Joe Root pounces. Four through the covers. He's up to 20 (30).
