Pompey suffered late heartache on three separate occasions in January.
So it was a relief to see a last-gasp goal work in their favour to secure a dramatic 2-1 victory at MK Dons.
Ike Ugbo’s effort midway through the first half looked to have secured the points for the struggling hosts.
But Matt Clarke headed Pompey level late on and there was still time for substitute Conor Chaplin to sweep home at the death.
And Kenny Jackett was pleased that his side were able to take advantage of nerves creeping into the Dons’ performance.
The Blues boss said: “I’m really pleased for the players because we had a few late goals go against us last month and it’s not a nice feeling.
“So it was great to see Clarke’s header go in and then for Conor to score in injury-time balanced things out slightly. It gave them no chance to come back.
"A goal can swing the confidence and we had a surge after the equaliser to get the winner."
“It had been frustrating because we were on top and then MK went down the other end of the pitch and scored.
“They’re a side who were battling to get out of the relegation places and I think everyone’s surprised that they are down there.
“So they were understandably quite edgy in the last 15 minutes and we took the two chances that counted.
“A goal can swing the confidence and we had a surge after the equaliser to get the winner. I’m delighted for Conor.
“We showed plenty of character to keep battling and it was certainly a reward for our fantastic travelling fans.
“It’s a big period for us now and we need to get a good run together so we can have a run at the play-offs.”
Chaplin came on at the start of the second half and was in the right place to score deep into stoppage-time.
Jackett said: “I felt we needed another forward to get closer to Brett Pitman and he kept going, getting his reward in the end.
“That can give him confidence and belief that he can go on a run – I certainly believe he’s capable of that.
“I’m also pleased for Luke McGee because he played a key role in an open contest that could have gone either way.”
