"Wrist spinners are mostly attacking but when your captain is so attacking, you get freedom to attack more," Chahal told reporters after India beat Australia by 26 runs under Duckworth Lewis method in the first ODI here last night.
"But sometimes, we also have to take a step back and you change your plans," he added.
Chahal, who took three wickets for 30 to be one of the architects of India's win, said having left-arm wrist spinner Kuldeep Yadav at the other end made things easy for him and both of them made plans according to the game situation when they bowled in tandem.
"Because we both look for wickets, there is no point in playing safe. You don't win matches that way," he said.

Chahal, who came to the fore with a series of impressive performances for Royal Challengers Bangalore in the IPL, said the experience of bowling at Glenn Maxwell in the cash-rich T20 came in handy in getting the big-hitting Aussie batsman out.
The leggie, who plays for Haryana in the domestic circuit, said Kohli and Mahendra Singh Dhoni also told him to bowl outside off (stump) and mix it up when bowling yesterday.
"Kuldeep's deliveries come in. So, Mahi bhai and Virat bhai asked me to push it outside and keep checking his feet. (Bowl) outside off and mix it up," he added.
"The way the wicket behaved, Mahi bhai and Pandya batted outstandingly. If we reached 230-240 and there was turn, we had Kuldeep and Kedar bhai. Obviously at 87 for 5, Australia were 70 per cent in the game. But the way they played, the momentum that came through (Adam) Zampa's over, and on this wicket 280 was a winning total. In the end, we bowled quite well.
