Tamim helps Bangladesh take England the distance
England 505 v Bangladesh 282 & 328-5
Centurion Tamim Iqbal smashed England to all parts of Lord's as the hosts discovered they will have to dig deep to complete their anticipated victory over Bangladesh in the first npower Test.
Tamim (103), Imrul Kayes (75) and Junaid Siddique (66 not out) made a mockery of England hopes for a quick kill on day four after they had enforced the follow-on, with their opponents 282 all out and still 223 behind.
Tamim and Kayes, who had posted their country's previous best opening stand against England in the first innings, quickly demonstrated that was merely a 'sighter' by rattling up Bangladesh's all-time record 185 for the first wicket on the way to a stumps total of 328 for five.
By the time Tamim fell in late afternoon - caught at deep backward-square trying to hook Steve Finn for yet another boundary - he had hit 15 fours and two sixes from 100 balls.
Finn doubled up with Kayes' wicket too, Ian Bell snapping up a sharp catch off the face of the bat at short-leg to give the Middlesex seamer his second success for a solitary run in 14 balls, as England sought to restate their authority.
But Junaid then shared another century stand with Jahurul Islam, Bangladesh steadfastly defying expectations of a collapse and ensuring instead England will have to wait well into the final day - and improve significantly with ball and even bat - if they are to go 1-0 up in this two-match series.
They were on to Plans B and C at least when Jonathan Trott dived forward for a caught-and-bowled off Jahurul's bat and pad for a maiden Test wicket which broke a hard-working third-wicket partnership.
Even then, though, there was a little more punishment in the offing for a tiring attack as the mercurial Mohammad Ashraful decided he wanted a piece of the action too - until James Anderson saw him off caught behind in his first over with the second new ball, which was also to account for nightwatchman Shahadat Hossain.
In 14 overs to lunch, Tamim and Kayes already had 61 on the board - typically going after anything wide or full as England failed to find their optimum lines and lengths on a benign pitch.
There was no compromise in the afternoon either, Tamim crashing boundaries almost indiscriminately - as well as slog-sweeping Graeme Swann twice for six in one over that cost 17 - while Kayes operated in a slightly more minor key on his way to and beyond a maiden Test 50.
Tamim might have been run out for the second time in the match, on just 11, had Trott managed a direct hit from cover as the non-striker dropped his bat responding to a call for a quick single.
On 30, Kayes edged Anderson through Swann's fingers low down at first slip - and both batsmen needed other occasional small elements of luck.
In between, though - as frustration turned to something closer to desperation for England - events were characterised by thrilling strokeplay, moderate bowling and a realisation that the options open to captain Andrew Strauss were limited.
While Tamim continued to blaze away, Kayes slowed on the way to his 96-ball 50 - spending 16 deliveries on 49.
It was not much longer before Tamim was manically celebrating his hundred, after clubbing his final four over mid-on off a hapless Tim Bresnan. Anderson had earlier finished with four for 78 and Finn four for 100 - opening up the transitory illusion that England could push for an innings victory with a day to spare.
Shahadat Hossain and Mahmudullah collected a rush of boundaries, after Bangladesh resumed on 237 for seven in pursuit of 306 to pass the follow-on mark.
But in bright and fresh conditions, the Bangladeshis lost Shahadat for a breezy 20 when he missed a slog at a full slower ball from Anderson and was bowled off his back pad.
Mahmudullah, perhaps preoccupied with trying to manage the strike in company with number 10 Rubel Hossain, then drove all round a straight half-volley and was also bowled by Anderson.
But it was Bresnan who finished the tourists off before they could make England sweat too much, taking his first wicket of the match when he had Rubel flashing an edge from a flat-footed drive high to third slip.
If England, or anyone in a meagre Lord's crowd, assumed that routine elimination of the tail was a preface to rolling over Bangladesh second time round they were soon to learn very different.
