Pompey extended their unbeaten league run to four games in their floodlit clash with Bristol Rovers at Fratton Park.
But all of those fixtures have ended all square and Kenny Jackett knows his side have to start turning draws into wins.
They fell behind to a Jonson Clarke-Harris penalty, with the same player later blazing a second spot-kick high over the bar.
The hosts’ leveller was sandwiched between them, as a Ronan Curtis delivery was turned into his own net by James Clarke.
But Pompey could not find another goal and Jackett insists they will continue to work hard in order to collect more points.
The Blues boss said: “We’ve drawn four games on the trot now and that shows we’re not far away from where we want to be.
“We’re a competitive side and hard to beat, but obviously at this stage of the season what we really want is wins.
"We’re trying really hard to get over the line and while we’re pleased not to get beaten, it’s victories that we’re going for."
“The opportunities are still there for us and we’re in a situation where we have to keep going and try to build momentum.
“We’re trying really hard to get over the line and while we’re pleased not to get beaten, it’s victories that we’re going for.
“It was quite cagey in the first half and very competitive, with Bristol Rovers defending well and we couldn’t open them up.
“Our wide men have been good all season, but found it difficult in one-v-one situations to get past their men.
“Omar Bogle came on and, like the other substitutes James Vaughan and Viv Solomon-Otabor, lifted the crowd. They all bring something different.”
Referee Neil Hair awarded penalties for apparent fouls by Tom Naylor and Jamal Lowe, although Jackett was not overly critical of the official.
He said: “You can maybe question the decisions right the way through the game, although generally we don’t do that.
“We tend to look at our own performance, what we’re trying to do and how we can improve, leaving the referee to do his job.
“The players are frustrated, but my own point of view is that these things happen, it’s part of football and you have to accept it.”
