Collingwood survived a tense start to play a vital innings for England
Paul Collingwood is confident England can take advantage of a strong position after two days of the third Test.
West Indies closed 511 runs behind at 55-1 and Collingwood said: "There's a groove going through the wicket and quite a few balls have misbehaved.
"If we can get some balls in there we will get something. We got a great wicket late on and as long as we hit the pitch hard we will do well."
Of his 113, he said: "When you score hundreds it is really satisfying."
Collingwood has now made three centuries in his last nine Test innings and his latest effort could help England back into the series after their heavy defeat in the first Test.
"I went through a lean spell last year but when you get into a run of form you want to make hay while you can," added Collingwood.
"You do have some bad days, you do have some periods where you don't know where your next run is coming from."
After surviving a brutal first ball that flew off the edge of his bat and over the slips, Collingwood was also hit on the helmet as he survived a testing spell before finding his touch with some trademark strokes.
"I just took a couple of blows to the fingers early doors, we had to get through, and we had another good day," said the Durham player.
"With the new ball going quickly it was very unlike Antigua which is normally slower."
He even outscored the usually more free-flowing Kevin Pietersen in their partnership of 94.
"Myself and Kevin like those situations, they get your feet moving and blood pumping," said Collingwood.
"It was a hairy spell that Fidel (Edwards) bowled this morning and myself and Kevin had to get through that."
Looking ahead to the remaining three days of the match he added: "We were all desperate to do well after Jamaica, it was obviously really disappointing and we have had two good days so far.
"It means nothing at the moment but we have got scoreboard pressure, we have got runs on the board and its been another good day for us.
"You do get value for your shots on this ground, it's still a pretty good wicket but hopefully we can exploit that halfway line that runs across pretty much on Freddie (Flintoff's) length, to be honest.
"Hopefully he will keep on homing in on that. The halfway line is going to come into it in a lot of balls."
West Indies coach John Dyson said he expected the wicket at the Antigua Recreation Ground to deteriorate further on day three.
"Some Test wickets are just too good, they shouldn't last the six or seven days they last," said Dyson.
"You expect a Test wicket to wear and start playing a few tricks, just how many we won't know until tomorrow. The main tricks have been played by the soccer line, not the wicket itself.
"I was a little disappointed with the way we bowled today, we didn't bowl as well as we could have.
"It's a matter on a wicket like that of being very patient and disciplined and we fell back into an old habit of trying to be too aggressive.
"Instead of just getting the occasional over or the occasional three or four balls that are very good, we're trying to extend the length of pressure that's applied."
