West Indies, in dire straits after losing three wickets on 36, had recovered to 120 for four in their second innings at stumps on the third day. That still left them 35 runs behind England’s first innings 398.
Chanderpaul, officially the world’s best Test batsman, dug-in to be 34 not out in two-and-a-half hours of typical defiance. Meanwhile, Samuels offered sound support in an unbroken fifth-wicket stand of 55 in 113 balls to be 26 not out at the close.
Shortly before stumps, England thought they had Chanderpaul lbw for 22. First-change Tim Bresnan, from around the wicket, had his appeal rejected by South African umpire Marais Erasmus but England captain Andrew Strauss called for a review.
However, replays indicated the ball would have missed leg stump. The West Indies, 155 behind on first innings, saw openers Adrian Barath and Kieran Powell put on 36 for the first wicket.
But in sight of getting through a tricky pre-tea session, Barath (24) was undone by Bresnan's fifth ball of the innings, an excellent leg-cutter he could only edge to wicket-keeper Matt Prior.
