Pompey put their League One ascent to one side this weekend with focus switching to facing Altrincham in the Emirates FA Cup.
Kenny Jackett’s side are the 1/5 favourites with Sky Bet to book their place in the third round at Fratton Park.
The visitors – who compete in National League North and beat York to get this far – can be backed at 12/1, with the draw at 5/1.
Pompey were 2-1 victors at Harrogate Town in the last round and a repeat of that scoreline carries odds of 9/1.
Punters expecting a more convincing performance might instead prefer to put their money on a 3-0 win at 11/2 or a 4-1 success at 16/1.
Or if you think they will have to battle from behind to progress like in the first round, then that is on offer at 9/1.
Reckon it will be a goal-fest? The hosts coming out on top in a contest that sees the ball find the net more than 4.5 times is priced 5/2.
Strikers Ellis Harrison, John Marquis and Brett Pitman are the joint 16/5 favourites to net the opener on Saturday.
Elsewhere in the first goalscorer market, Ronan Curtis, Ben Close and Christian Burgess are available at 4/1, 9/1 and 40/1 respectively.
A more outlandish – or some would say optimistic – bet is for Pompey to be lifting the FA Cup at Wembley in May at a mighty 250/1.
