"It is amazing, a special feeling to score a century in T20 cricket. This is my first in this format, so it has to be my favourite," Pietersen told reporters after smashing an unbeaten 64-ball 103, his first in Twenty20 cricket, to help Daredevils register their fourth victory in IPL V.
"It is good to get a century in T20 cricket. It was a good wicket to bat on and also good for the pacers who bent their back, not much for the spinners. In Twenty20 you need entertaining wicket," he added.
The former England skipper, who was adjudged Man-of-the-Match for his whirlwind ton, said he tried to play according to the situation.
"I played as per the situation. Once you get yourself in there, you can get the boundaries. I was in good form against Sri Lanka and it is all about backing yourself in the field," Pietersen said.
"When you lose wicket, you slow down and Ross's (Taylor) wicket put pressure on me. They (Deccan) played good cricket," he added.
