Karl Robinson says Charlton will change their style of play against Blackpool because of the pitch.
The Tangerines’ playing surface is one of the worst in the Football League.
Valley chief Robinson said: “It’s something we’ve been working on.
“We’ll change how we play, we can’t be as nice as we want to be. We don't want to get caught in a high press or from a human error.
“We feel if we play higher up, we’ve got very quick players in our backline. We feel we've got an aggressive frontline which is full of confidence.
“Confidence has got to be something that makes you better, not something that makes you relax. We’ve got to make sure we go there in a very strong frame of mind.”

It will be an emotional day for Blackpool fans after club legend Jimmy Armfield died of cancer on Monday.
Tangerines boss Gary Bowyer and Robinson will lay a wreath in front of the Jimmy Armfield Stand before kick-off.
The Liverpudlian added: “It’s going to be a difficult afternoon, all their players will be fully motivated after the passing of Jimmy Armfield.
“It’s been a difficult week for everyone concerned with Blackpool. I know there will be a minute’s applause and a speech read out by a family member so it will be a touching occasion for everybody concerned.
“But once the whistle goes, that’s gone, but it will give them an impetus. We've got to make sure we’re ready.”
