Pompey are searching for a third successive victory when they host Southend this weekend.
And Kenny Jackett’s side are the 17/20 favourites with Sky Bet to secure all three points at Fratton Park.
The visitors – who are only below the Blues on goal difference – can be backed at 16/5, with the draw at 13/5.
Backing the Blues to triumph by either a 1-0, 2-0 or 2-1 scoreline carries odds of 15/8, while a 3-0, 3-1 or 3-2 victory is priced at 11/2.
You can also take a punt on the margin of a Pompey win, with one goal at 11/4, two goals at 4/1 or three or more goals at 6/1.
Alternatively, you might want a flutter on the Blues recovering from an interval deficit to come out on top at 25/1.
Brett Pitman is the 7/2 favourite to net the opener or 33/1 to grab his first hat-trick in a Pompey shirt.
Elsewhere in the first goalscorer market, Oliver Hawkins, Jamal Lowe and Christian Burgess are available at 5/1, 17/2 and 33/1 respectively.
