The ball has done something and England will be very happy to get to lunch at 81-3. Joe Root has been very calm, quietly positive, played one big shot to try and change the tempo of the game and then picked off the spinners. It shows good batsmen can survive and even prosper here. 

In case you've only just got up (what time do you call this?!), you've missed a fascinating first session. Bangladesh have made the most of a turning surface, reducing the tourists to 21-3, with 18-year-old debutante off-spinner Mehedi Hasan Miraz opening the bowling and taking 2-13 in his first 10-over spell.

Once again, though, England are thanking their lucky stars for one Joe Root, who has looked a class above everyone else wielding a willow, scoring 38 in a partnership of 60 with Moeen Ali.

Time for some leg spin as Sabbir Rahman is brought into the attack. Things remain pretty much the same - Root cool and calm, Moeen nervous and uncomfortable. There is an appeal against the latter as he goes back and the ball flicks the pad, but he is way outside off stump and the calls quickly wither away. That is your lot for the first session - it has been gripping stuff. Literally.

A very timely reminder to England that they cannot relax. The pressure is constant.

Moeen survives by the finest of margins. He offered his bat to the umpire after the shot as if to say he hit it and this is backed up by Ultraedge, which shows the tiniest flicker of noise.

There is a squiggle, is that a sufficient squiggle? I told you it was a nightmare to be a third umpire.

Moeen has been trapped lbw sweeping and the finger goes up. Moeen is quick to send it to review, but he looks in trouble.

Even when the ball is turning the really good players judge the length well and the amount of turn and suddenly you think nothing much is happening.

Root plays every shot with such authority. Everyone else has looked like they are poking a sleeping monster with a stick but the Yorkshireman trusts his instincts and his ability. He sweeps for two to bring up the 50 partnership with Moeen. They are then given a gift as Taijul chucks one down leg that beats everyone before running away for four byes. England are tiptoeing out of deep trouble.

Eddy McEdFace: Root looks (or should I say 'sounds'?) like he's batting on a different pitch as usual. Sheer class. 

More spin than Alastair Campbell on the waltzers. Shakib returns and the pressure remains. His short leg won't thank him for a short ball that Root rocks back and pulls into the back of his thigh. Bangladesh have rattled through the first 25.

If you are the third umpire you suddenly come to the realisation that it is going to be a busy five days and there is going to be no respite. What you want is to be in Perth, where the ball is never going to get you lbw, and you can put your feet up.

Moeen is given a gift as Taijul drops short with his last ball, allowing the batter to pull away for four.

Moeen survives via umpire's call on impact. They took their time making the decision, though. Nervous times for England.

The TV cameras have just picked out a table full of burgers and hot-dogs that look like a couple of days on the pot in the making. On the pitch, Moeen is in all sorts of trouble to Taijul as he is caught on the pad playing a forward push. Bangladesh are going to review this.

Root hasn't played risky shots, there was an early slog sweep but other than that he has just picked off the bowlers beautifully.

It initially seems strange that Bangladesh are persisting with the seam of Kamrul, but his first ball gives an indication as to why as it stays low and beats Root outside off. It is the only ball that poses a serious threat to Root, who cuts the last ball for four. I suspect that will be the last we'll see of Kamrul for a bit.

Moeen can be quite loose as a batter, he doesn't move his feet and can get stuck. Being the sub-continent it is a slower wicket and it is an opportunity for him to knuckle down, but it's a tough winter to try and establish your batting line-up because we are still looking for an opener and a settled middle order.
