India were left with the herculean task of chasing a world record 420 after England refused to declare in an unfocussed second essay, cut short by Ravichandran Ashwin's brilliance on a sharply turning fourth-day strip in the opening Test here on Monday. At stumps, India were 39 for one, requiring another 381 runs to set a new record and take a 1-0 lead in the four-match series. The previous best is 418, chased by West Indies against Australia in 2003. Relishing bowling on a responsive pitch, the seasoned Ashwin returned excellent figures of 6/61 to snap England's second innings at 178 after the home team conceded a massive first-innings lead of 241 runs.
