Freezing temperatures ensured Pompey were left kicking their heels at the weekend.
Their scheduled trip to Crewe was postponed, with plenty of other fixtures across the EFL suffering the same fate.
But there was some good news, with promotion rivals Charlton, Doncaster, Hull and Lincoln all dropping points.
Ronan Curtis admits that was a boon for the Blues, but knows they have to capitalise at Bristol Rovers this evening.
The Republic of Ireland international said: “The postponement was disappointing because after the good result against Swindon, we wanted to keep the run going.
“You work hard on the training ground for a game on Saturday and then it’s called off, but we’ve got to put that behind us.
"The lads are feeling very confident and if we keep winning games, then we know we’ll be right up there."
“There were a few good results for us at the weekend and hopefully we can make the most of that when we visit Bristol Rovers.
“You can’t worry too much about anyone else in the league, though, and so we’ve just got to keep looking forward.
“The lads are feeling very confident and if we keep winning games, then we know we’ll be right up there.
“It’s going to be tough against Bristol Rovers and anyone can beat anyone in this league, but we want to come out on top.”
Curtis has netted in each of Pompey’s past two games to take his personal tally for the campaign into double figures.
He said: “I’ve been here for three seasons and when I arrived, I immediately said I wanted to score and assist goals.
“I’m glad I’m on a little run now with two in two and hopefully I can continue that. I’ve scored in the last two games at Bristol Rovers and want to help the boys to another win.”
