Trinidad: England lost the wickets of their captain Andrew Strauss, stylish No.3 Owais Shah, and their vice captain Alastair Cook in a dramatic hour and 10 minutes before stumps were drawn on the penultimate day at Queen's Park Oval.
The visitors had earlier gained a lead of just two runs, after Chanderpaul scored his 21st Test hundred, an undefeated 147, and Nash made his maiden Test hundred of 109, as West Indies were dismissed for 544, replying to England's first innings total of 546 for six declared.
Chasing quick runs before the close in a desperate bid for a series-levelling victory, England soon ran into trouble.

Before lunch, England endured a fruitless toil, as Nash reached his maiden Test hundred and helped West Indies reach 433 for four at the interval.
England began to see signs of a last-ditch effort for victory ebb away, when Nash and Chanderpaul held firm throughout the morning period.
