Dundee are a massive 14 points adrift of league leaders Ross County and Paddy Power price up the hosts as 4/7 (1.57) favourites to grab an essential victory here.
Ayr United are just four points clear of the First Division's basement club, Queen of the South and just two points in front of Raith Rovers, who occupy the relegation play-off position, and the Honest Men are an honest price for victory at 4/1 (5.0) with Paddy Power. The same firm rate the draw as an 11/4 (3.75) shot.
Dundee are unbeaten in their last eight league matches, having won three and drawn five of those matches and Paddy Power make the Barry Smith's side 13/2 (7.5) to win 2-1 on Tuesday while the Irish bookmaker offers odds of 6/1 (7.0) for a 1-1 draw.
Despite their lowly league position, Ayr United have been in impressive form in recent weeks, recording home and away victories over Livingston as well as beating title hopefuls Falkirk at Somerset Park.
Ayr suffered a setback at the weekend after being edged out of the Scottish Cup by Scottish Premier League side Hibernian but that might prove to be a blessing in disguise for Brian Reid's part-timers, who are priced up at 14/1 (15.0) with Paddy Power to win 1-0 on Tuesday, while the same firm go a massive 30/1 (31.0) on a 2-0 victory for Ayr.
With both sides in good form, this promises to be a much closer match than first glance at the league table might suggest and the value lies in Dundee being forced to settle for a share of the spoils once again.
