Similar to the game against Aylesbury in the FA Trophy, Rovers were second best in almost every department as Woking strolled to victory to keep them on track for the play-offs.
The visitors went in front after 21 minutes when Rovers captain John Richardson was caught out by former team-mate Jefferson Louis who laid the ball back for Karl Murray to fire past Steve Perrin from the edge of the area.
Within two minutes the lead was increased and Richardson again was at fault.
He mis-controlled a seemingly unthreatening ball forward and Woking capitalised with a superb strike from Justin Richards which flew into the top right-hand corner.
It could have been three when again dreadful marking left Luke Oliver in possession on the edge of the area but the defender's attempted chip was tipped on to the crossbar by Perrin and acrobatically cleared by Damon Searle.
Against the run of play Rovers got back into the game just after the half hour.
Charlie Griffins' shot looked to be well wide but a wicked deflection off a defender wrong footed Woking keeper Shwan Jalal.
Nine minutes into the second half the game was all over when a standard cross from the right wing found Oliver in the area.
Once again he was completely unmarked and without a Forest Green defender in sight he was more than capable of heading the ball beyond Perrin's reach to leave Forest Green's mood as cold as the weather.
