Guiseley gained revenge for two defeats at the hands of the Magpies earlier in the season with a narrow victory at Nethermoor.
After an even and lively opening quarter of an hour the home side stepped up a gear. Paul Jarvis was called into action to make a goal line clearance from a corner, but two minutes later a free-kick from the halfway line landed nicely for Adam Boyes who slotted beyond Sam Ashton.
Chorley came close to a leveller just before the half hour point when a Josh Hine header sailed narrowly wide of Steven Drench’s right hand post, but ten minutes later the match was tied.
The Magpies worked the ball from a Jarvis through around the box where Andy Teague was positioned on the right wing; the skippers cross was met by the reliable head of top scorer James Dean.
Into the second half and Boyes doubled the lead when he fired in from 18 yards after Chorley failed to clear a Guiseley throw.
Josh Hine shot straight at the keeper, Dean forced an acrobatic save from Drench and Winter’s 35 yard effort was gathered by the keeper at the second attempt as the Magpies searched for a way back, while at the other end Sam Ashton was called into action in a 1-on-1 and did superb to save one handed in the injury time.
