Birmingham manager Lee Clark feels his side fed off the tension around Leicester's King Power Stadium to snatch a 2-2 draw on Friday night.
A win would have seen the Foxes edge into the Championship play-off places ahead of the weekend's fixtures, and it looked like Nigel Pearson's side were going to end their eight-game winless run after Jeff Schlupp had headed them back in front.
But substitute Chris Burke, back after a three-game absence with an ankle injury, kept his cool to net a last-minute penalty to snatch a point for the visitors.
Curtis Davies' own goal saw Leicester take an early lead but Nikola Zigic equalised just after the hour mark.
"We knew there would be a bit of tension around the place because Leicester and Nigel will be thinking they have to win because it (the race for the play-offs) is so tight," said Clark.
"This is a big club and there is a certain expectation level here and we knew we had to use that in our favour as part of our armoury.
"We spoke about it pre-match - making sure we use that bit of tension around the place to our benefit.
"But that aside, I felt we deserved the late goal. It would have been a travesty really if we had come away from here with nothing."
Leam Richardson's men moved five points clear of the drop zone ahead of Saturday's games as they continued their strong form against the Shrimps, who are now without a win over Stanley in 12 league attempts.
Murphy, who scored a last-gasp equaliser at York on Saturday, opened the scoring after 28 minutes against the run of play.
Lee Molyneux's low 30-yard free kick was deflected into the net by the defender to wrong-foot goalkeeper Barry Roche.
Morecambe looked dangerous at times with Robbie Threlfall's in-swinging corner tipped over by home keeper Paul Rachubka.
But Stanley's defence held firm and the home side scored their second from a counter attack as the hour approached.
Rommy Boco ran from midfield and rounded Roche but his shot was blocked. The ball fell to Amond, who blasted home from 12 yards through Chris Doyle's legs to seal a crucial win.
