Smith's wicket was more satisfying: Ashwin

India off-spinner Ravichandran Ashwin termed his delivery to dismiss Steven Smith as a more "satisfying one" compared to the one that helped him get rid of Mitchell Johnson on the opening day of the fourth and final Test against Australia.

"I believe getting Smith out was more satisfying. In case of Johnson, it was an error of judgement on his part that helped me get his wicket," Ashwin, who had best figures of 4-40 on the day, answered to one of the four questions that were asked to him.

To a query about how different the Kotla strip was in comparison to the Chepauk pitch, he answered with his now customary swagger.

"That's red soil and this is black soil!" adding: "It's always evident that on black soil the ball doesn't bounce as much as on the red soil."

Asked about the assistance one got from the wicket, he replied, "If there are spots on the wicket, then one shouldn't get carried away as margin of error is very less. One shouldn't try too many things from back of the hand."

In all the Tests so far, the Aussie tail has wagged but Ashwin differed in his stance.

"I don't think that has been a problem (wiping off the tail). They have batted pretty well. We have to stick to our guns and see what happens. In different scenarios, different teams do well and that era is over when tail-enders would come, slog and get out. Pattison has an average of 30," he answered.
