Moises Henriques is still hopeful Australia can pull off a miraculous victory over India despite having their backs to the wall with one day left in the first Test.
Henriques made an unbeaten 75 as the no 7 batsman and Nathan Lyon produced 57 runs for the last wicket at the end of day four to frustrate the hosts.
Australia will begin the final day with a 40-run lead in Chennai but although the Indians, helped by Mahendra Dhoni's knock of 224, are clear favourites there remains some hope for the tourists.
"I thought Nathan and myself did a pretty good job at the end," Henriques said. "Nathan hung around and once you hang around and get set, it does get easier.
"After watching Mahendra making it look easy and spending time out there, I thought it might get easier for us. Luckily I've been lucky enough to hang around for a little while after my run out chance."
On the chances of producing a shock victory, the 26-year-old Portuguese-born Australian added: "You can only dream of things like that.
"Hopefully Nathan and I can bat like that again in the morning. We'll just see what happens tomorrow."
India resumed on 515-8 at the start of Monday and added 57 before being skittled out having built a lead of 192.
