Pompey are chasing an eighth successive victory when they host Southend in league action on Saturday.
And Kenny Jackett’s table-topping side are the 4/6 favourites with Sky Bet to secure all three points at Fratton Park.
The visitors – who are currently sitting 14th in the standings – can be backed at 19/5, with the draw at 11/4.
Pompey triumphed 1-0 in the corresponding fixture last season and a repeat of that scoreline carries odds of 6/1.
Punters expecting a more comfortable afternoon might instead prefer to put their money on a 2-1 win at 15/2 or 4-0 victory at 28/1.
And those anticipating plenty of excitement could be tempted by the Blues coming out on top in a contest that includes more than four goals at 13/2.
You might also be interested in Jackett’s troops battling from behind to eventually secure the points at 10/1.
Ronan Curtis, Oli Hawkins, Jamal Lowe and Brett Pitman are the joint 9/2 favourites to net the opener.
Elsewhere in the first goalscorer market, Gareth Evans, Ben Thompson and Jack Whatmough are available at 13/2, 16/1 and 33/1 respectively.
