POSSESSION may be nine tenths of the law but Linnets were unable to make it count.
They not only had most of the ball but also spent a lot of time in their opponents' territory and had enough chances to have won comfortably.
But a combination of poor finishing and heroic defending saw the struggling Cumbrian hosts hold on for a draw.
It was enough to take the Barrow-in-Furness side off the foot of the table and cut Runcorn's lead at the top to a single point.
Winsford, who struck a last-gasp home winner against Cheadle on Saturday, now have two matches in hand and the clash of the two at Wincham Park on Tuesday, October 24 is starting to look vital.
Linnets fans were shocked to find right winger Andy McCoy arriving at the ground on crutches after an accident at work.
But, in his absence, Mick Young found plenty of early space if on the opposite flank.
Manager Steve Carragher had warned complacency would be key but there was no lack of commitment. Runcorn's only problem was finding the net.
Holker's defence stuck grimly to their task and every time Run-corn looked to be on the verge of scoring they threw in a saving tackle, block or interception to make it easily the most frustrating match so far for Linnets.
The visitors weren't helped by decisions from the officials. In the first half, Young and Thomas Lamb were denied cast-iron penalties after being brought down.
After the restart, some of the referee's rulings verged on the farcical.
Linnets were also hindered by Holker scoring from a rare first-half chance on the half-hour mark as this gave the Old Boys something to cling onto.
Callum Livingstone's low shot forced a good save from George Caulfield, diving to his right. But Rob Bruce pounced on the re-bound to send Holker's players into raptures.
For the most part, Caulfield had so little to do he could have been forgiven for taking in the panoramic views of the Lake District offered by this remote, elevated little ground on the outskirts of town.
By contrast, Holker keeper Sam Stephens and his defence had to repel a lot of pressure.
Stephens never looked totally secure but invariably held onto shots and when he didn't, the ball never seemed to fall to a Runcorn player.
Linnets were also guilty of over-complicating their attacks, particularly before the break.
The spectre of defeat hung over them until the 63rd minute when by playing it simple they equalised.
John Morgan, replacing McCoy, crossed from the right and Lamb headed home at the far post for his sixth of the season.
This was enough to take him clear of five-goal team-mates Dave Thompson and Young as Linnets' top scorer outright.
But Linnets could not get the second they craved as defiant Holker stood firm.
