The veteran South African, currently ranked the world's top one-day bowler, knows most batsmen will approach the 20-over format with all guns blazing and rewrite the economy rate conventions.
For Pollock, who finally hit his maiden one-day century in June more than 11 years after his debut, the only chance of redemption will be if he gets a chance to open his shoulders himself once the tournament begins next Tuesday.
"I think if you are only a bowler in this form of the game it would be pretty depressing," said Pollock.
The 34-year-old former skipper, who has an impressive economy rate of only 3.7 runs an over in ODIs, said that he would have to adopt a "different mindset" during the crash, bang, wallop of Twenty20.
His biggest battle would be to settle into a rhythm quickly, well aware that he will not have the usual luxury of a few overs to settle in, Pollock told reporters in Johannesburg.
"There is obviously a little more pressure, but you just have to go out there and express yourself," he said. "I normally take four overs and by then it is done and dusted.
"I wouldn't have a clue what a good economy rate is in T20," he added.
The Proteas will get the inaugural Twenty20 championships under way on September 11 when they line up against the West Indies at the Wanderers stadium in Johannesburg.
Pollock is the veteran of the squad which is minus star batsman Jacques Kallis, whose dropping has been the main topic of conversation among South African cricket followers.
His long-time teammate Pollock said the exclusion would have been a big surprise and a disappointment for Kallis who is considering his position as the Test team's vice captain after being dropped.
"He would have been very surprised not being able to play in front of his home crowd. He would have been very disappointed," he said.
If the Twenty20 was seen as anathema to Kallis's game, it should suit big-hitting batsman Justin Kemp down to the ground.
"With T20 it is in and out and over and done with," said Kemp who has a strike rate of nearly 90 runs per 100 balls in ODIs.
"It's basically a helter-skelter from ball one", said the right-handed batsman.
