The Pirates come to WD4 locked into a battle for the league title following their promotion to Step 4 at the end of last season and Jordan Parkes' men will need to be at their best to stop the league's highest goal scorers.
Kings' forwards will be in for a tough evening as well with Real Bedford boasting the league's stingiest defence.
The home sides fading play-off hopes largely hang on improving their home form, with their last home win coming back in September- a 3-1 win over Northwood on 'Boxing Day' (the fixture was moved).
With forward Jake Anthony returning to Harpenden Town and Lorenzo Johnson joining Arlesey Town, Jordan Parkes has responded by bolstering his team with several youngsters on loan from Football League clubs who will be hoping that their first tastes of senior football are successful ones.
Kings 0-0 draw at Hertford Town on Saturday was their first goalless match in two years and we can almost certainly expect a Christmas goal bonanza on Tuesday night.
