Thomas Measures: Can sense a collapse coming. Broad will produce one of those magic spells.

Merlyn: Game on now. Broad I take my hat off you've bowled well this match. Long overdue.

What a moment for Shivnarine Chanderpaul, the grand old man of West Indian cricket who may even be playing his farewell Test innings - and he could hardly have asked for a more suitable scenario to give us one last masterclass in obduracy and resilience. Bravo plays out a maiden from Joe Root - that's five maidens in a row now, West Indies are stuck in the mud here.

"The ball cut Samuels in half; it was through him in no time. I think he is getting back to his best is Stuart Broad. He's one of the England players that can go home very happy - with his bowling that is - I'll not talk about his batting."

Magnificent from Stuart Broad! He set Marlon Samuels up, getting the ball to shape away from the batsman and then sneaking an inswinger through the gate. Samuels was so comprehensively defeated by that delivery that he ended up down on his knees. That's one of West Indies' key batsmen dismissed, and this Test match teeters on a knife-edge again.

"I think Bravo is ready to crack, he's been there a long time for 15."

Ooh, Darren Bravo nearly gives it away with a swipe at Joe Root which lands agonisingly short of mid-on. There's real turn here for Root and he draws a false move from Bravo again, under-edging one that fortuitously evades the stumps.

Just a hint of trepidation on the faces of Alastair Cook and Jos Buttler. England need to end this stand pronto. Stuart Broad is giving it his best shot, sending a leg-cutter just past the groping bat of Marlon Samuels and then getting one to just hold its line and defeat the blade again. High-class fast bowling, but no rewards for Broad as yet.

"If England are going to win there's going to have to be a collapse, a frantic half hour, that changes the momentum."

The Golden Child, Joe Root, enters the fray to provide another spin proposition. He begins with a good maiden to Darren Bravo.

Chris Jordan is off, and Stuart Broad is back. Samuels produces a lovely, elegant flick through midwicket, just stroked off his toes with languid, easy grace. Then Samuels steers one through point and Ben Stokes, a man who never seems far from a fit of rage, is absolutely furious with himself for failing to stop it with a sprawling dive. Eight off the over, West Indies going along at a decent clip here.

"England have to keep thinking, add two wickets to that score and then it's not so easy to get to 192."

England can't afford too many freebies from Moeen but the spinner shows no signs of having conquered his propensity to send down one filthy delivery per over. Too short again and Bravo swivels and hoicks him over mid-on for four. Bravo has a rush of blood next ball though, driving loosely, and he's fortunate to see the ball just dip under the toe of the bat.

Chris Darby: If the Windies win this then Cook should resign the captaincy and Moores should quit as head coach. Neither of which will happen.

Darren Bravo brings up the West Indies 50 with a cute little nudge off his hips down to the fine leg boundary. Hands on head from Jordan. Sub fielder Adam Lyth then distinguishes himself with an erm, lithe, piece of fielding to stop a Bravo cover-drive, but the next shot squirts a little squarer and brings two. And then Bravo pockets two more with a thrash through the covers. Eight off the over, a good one for West Indies.

Moeen continues. There's a bit of uneven bounce on display - the odd ball is just keeping low and defeating the West Indies batsmen. Joe Root manages to prevent a single with a really good stop from Marlon Samuels.

Owen: All this talk of a quick bowler needed- I remember a certain Steven Finn being England's next big thing... When does he come back?

Samuels and Bravo inch West Indies closer to the target with a couple of singles off Jordan.

"It's going to be a total pressure cooker of a finish, you can feel it."

Ooh, that's another horror from Moeen, half-tracker that Samuels bludgeons for four that only just avoids decapitating the man at short leg, not for the first time. But Moeen comes back really well, producing an absolute doozy that grips and spins past the tentative prod of Samuels. Good contest, albeit not one that you'd necessarily want a front-row seat at short leg for.
