Kirk Hudson's sparkling double all-but consigned battling Chester to non-league football next year after a thrilling 2-2 draw.
Hudson struck a unstoppable volley in either half and despite Ryan Lowe and Lee Ellans twice equalising Mark Wright's men now require a mathematical miracle to overhaul Grimsby at the foot of League Two.
Things had looked rosy after 25 seconds when Chester were awarded a penalty after 18-year-old Ellans was bundled over by Shots skipper Ricky Newman.
Top-scorer Ryan Lowe lashed home on the rebound after Nikki Bull saved his original attempt.
But Aldershot hit back after 15 minutes when Hudson beat the Blues' offside trap and spectacularly lobbed Chester's emergency loan signing Jamie Spencer.
Hudson started where he left off 11 minutes after the break smashing another vicious volley past Spencer.
But Chester controversially drew level in the 63rd minute. Lowe diverted James Vaughan's shot goalwards and despite home keeper Bull lying injured on the ground trainee Ellans fired home.
The visitors laid siege to the Shots net late on but trailing Grimsby by three points with a game remaining they now require a 20-goal swing to beat the drop.
