Pompey will look to put their first League One points on the board when they host Tranmere on Saturday.
And Kenny Jackett’s side are the 8/13 favourites with Sky Bet to secure victory at a packed Fratton Park.
The visitors – who were promoted via the play-offs last term – can be backed at 17/4, with the draw at 11/4.
Pompey triumphed 3-2 when the sides last faced off four years ago and a repeat of that scoreline carries odds of 28/1.
Those expecting a more comfortable contest might be tempted by 13/2 for a 2-0 win or even 25/1 for a 4-0 success.
The Blues battling back from an interval deficit to emerge on top – which happened in that last meeting – is also priced at 25/1.
But the bookies instead believe that the hosts will win both halves, which has the shortest odds of 11/8.
Both sides finding the net in the first half is on offer at 4/1, while the same thing happening in the second is 5/2.
You might want to take a look at the winning margins market, with Pompey succeeding by one, two or three-plus goals available at 5/2, 7/2 and 9/2 respectively.
And those taking a longer view might be interested to see that the Blues are the joint 15/8 second favourites to secure promotion.
