Halifax produced a sensational second half performance to thrash Dewsbury 60-6 and storm seven points clear at the top of the Championship.
Karl Harrison’s league leaders only led 16-6 at half time after a patient, methodical performance on a heavy playing surface which was only finally cleared of snow in late afternoon.
But they were simply irresistable after the restart, piling up 44 unanswered points with seven almost exclusively spectacular touchdowns.
Winger Rob Worrincy finished with a hat-trick, while there were doubles for Anthony Thackeray, full back Ryan Fieldhouse and substitute loose forward Craig Ashall as Fax finally hit top gear in attack.
They had almost scored with their first touch of the ball, centre Ben Heaton storming away down the left before the cover converged.
Ironically, it was the Rams who scored first through Scott Hale, Dale Morton converting, but Fax were on the board when captain Scott Murrell produced a great pass to set up Fieldhouse.
Lee Paterson’s missed kick meant the Rams still led 6-4, but Thackeray’s two tries either side of the half hour, both converted by Paterson, set up that interval advantage.
The second half was virtual one way traffic from the moment Worrincy plucked a kick out of the freezing air and hared 60 metres to score just four minutes after the restart.
Fax moved up a gear in attack and defence and the Rams were left floundering as Worrincy, Ashall and Fieldhouse all romped in on the back of some brilliant build up play.
With Steve Tyrer taking over the kicking, Fax had the game won by the 56th-minute, when they led 36-6.
There was a brief lull after that, but Tyrer, Ross Divorty , Worrincy and Ashall - who celebrated with one swallow dive to touchdown and then another into the mountain of freshly-cleared snow in front of the South Stand - all crossed in the final quarter to underline their side’s excellence on the night.
