That Marley Watkins goal saves Kilmarnock's blushes at the break.
There wasn't too much between the sides, and Cove could well have taken the lead had Rumarn Burrell punished his old side early on.
Can they answer back in the second period?
A first half that started at a furious pace and as an even contest ends with Hibs exerting most of the pressure without seriously threatening an opening goal.
Mark Ridgers has only had to make one decent save and, while Caley Thistle haven't threatened at the other end, home boss Duncan Ferguson will think his side are well capable of overcoming their top-flight visitors.

Hibs midfielder Joe Newell flashes a 20-yard drive over the crossbar as the visitors end the first half in command - but still no breakthrough.
The visitors will feel hard done by after starting strong at Pittodrie, but it’s that man Bojan Miovski who has twice punished the League Two side inside the opening 45.

Marley Watkins
The Premiership side find the breakthrough right at the end of the half.
Corrie Ndaba rises highest from a corner and nods down, allowing Marley Watkins to grab his second goal in four days as he flicks home.
Tough to take for League 1 Cove, they've been well in this.
Partick Thistle 1-0 Livingston
Kerr McInroy thunders in from range to give Thistle a one-goal lead over their top-flight visitors.

Bonnyrigg continue to attack in an attempt to cut the deficit in half by the break.
Just moments after Angus Mailer's strike on goal is blocked, Bradley Barrett forces a save from Ross Doohan after twisting and turning his man in the Dons box.
Partick Thistle 1-0 Livingston
Livingston thought they had the equaliser, but Tete Yengi's bullet header is ruled out.
I'm not quite sure why, but the Australian isn't happy.
Partick Thistle 1-0 Livingston
Not good news for Livingston. They've just made their second enforced injury substitution in the first half.
Mo Sangare and Andrew Shinnie have replaced the felled Scott Pittman and Shaun Donnellan.
Inverness Caledonian Thistle 0-0 Hibernian
Hibs threaten on the break as a superb ball finds Martin Boyle in the clear, but centre-back Remi Savage blocks the winger's volley.
Kilmarnock 0-0 Cove Rangers
The hosts' best chance of the afternoon.
Kevin van Veen doesn't need much sight of goal to sniff out an opportunity, flicking on a corner with a deft touch.
He so nearly opens his Killie account, but the ball bounces off the crossbar and the relieved visitors clear their lines.
Aberdeen 2-0 Bonnyrigg Rose
Not long after Smart Osadolor's low strike whizzed wide of Ross Doohan's goal, Aberdeen have begun to pester the Rose defence once again.
Centre-back Kerr Young is twice called into action for Bonnyrigg, first clearing a threatening Duk strike across goal before blocking a dangerous effort from range.

The life has been sucked out of the Rose support a little bit after they enjoyed a bright start, but Smart Osadolar is trying his hardest to give them something to cheer about.
The striker's latest shot just grazed agonisingly wide of the post.
Kilmarnock 0-0 Cove Rangers
Kilmarnock fans really weren't happy with their first-half performance against Livingston on Wednesday.
Not sure they'll be too much happier this afternoon. There's not much between them and their third-tier opposition.
Aberdeen 2-0 Bonnyrigg Rose
With two goals already this afternoon, Aberdeen's key man is edging closer to the 30-goal mark his new gaffer expects from him by the season's end.
Light work, surely?

James Carragher is a bit lucky to just earn just a yellow card for a badly timed, studs first tackle from the Caley Thistle centre-back.
Kerr McInroy
Apologies Kerr, I just saw a bald man spank it into the bottom corner and thought it was Stuart Bannigan.
Instead it was McInroy who absolutely arrowed it in from about 30 yards.
Michael McGovern had no chance.
Inverness Caledonian Thistle 0-0 Hibernian
John Robertson
Former Scotland striker on BBC Sportsound
Duncan Ferguson will be pretty pleased. Hibs have had a couple of chances, as you would expect, but it is pretty even and Inverness definitely believe they can win this.
Bojan Miovski
And another for Aberdeen's main fella.
It's a sickener for Rose as Miovski's volley is deflected in off Kerr Young.
Neat play from Leighton Clarkson and Dante Polvara teed up the forward, with that Premiership class starting to shine through from the home side.

This is already proving to be an intriguing battle on the near side.
Nicky Devlin has just saved his side's skin with a goal-line clearance, but he's being made to work for his money with the lively Bradley Barrett keeping him on his toes.
Quite the foot race. I'm exhausted watching them.
