Australia's spin-bowling dramas have taken a new and dark twist as their revamped attack claimed only one wicket in a day of batting brilliance from India in the second Test.
The home side reached 1-311 at stumps in Hyderabad on Sunday, a lead of 74 with nine first-innings wickets in hand.
Inexperienced pair Cheteshwar Pujara and Murali Vijay shared a record, unbeaten second-wicket partnership of 294.
It was Pujara's fourth century in his 11th Test. The 25-year-old's unbeaten 162 has included 25 fours and one six from 251 deliveries.
The 14-Test opener Vijay, 28, is 129 not out from 288 balls in a fine supporting knock to the dazzling skills of Pujara, who reached his 150 by hooking paceman Peter Siddle for six.
