Title hopefuls Rangers were surprisingly held to a 2-2 draw with Dundee United whilst St Mirren and Falkirk maintained their 100 percent records after two games of the SPL season.
Paul Le Guen's first home tie promised to be a difficult affair early on as United took the lead after just 14 minutes when Noel Hunt evaded the close attentions of Karl Svensson to convert Stuart Duff's corner.
The visitors then made the Frenchman's afternoon twice as painful as Norwegian full back Christian Kalvenes, on his debut for the club, rose high to head home a Barry Robson corner on 55 minutes.
Le Guen responded by bringing on Chris Burke and the young winger made an immediate impression as he turned in the box and beat Derek Stillie at his near post.
The Gers boss tried to repeat the trick by introducing new striker Filip Sebo for his debut, but it was a United substitute - Steven Robb - who did the damage when he headed past his own keeper with 11 minutes to go to spare Le Guen's blushes.
Kilmarnock bounced back from their opening day defeat to Celtic as they came from a goal down to beat Hibernian 2-1.
Tony Mowbray's side took a first-half lead with a cultured strike as Dean Shiels received the ball from Michael Stewart inside the box and lofted the ball over the home keeper.
However Killie placated their restless home support just three minutes after the break when Colin Nish volleyed home from close range.
The Rugby Park faithful were cheering again on 72 minutes when Scottish Under-21 international Steven Naismith produced a moment of sublime inspiration to embark on a weaving solo run which he capped with a precise finish.
A first half goal was enough for Falkirk to maintain their 100 percent record as they beat bitter rivals Dunfermline 1-0.
The home side took all three points thanks to a well-directed corner from Russell Latapy as Darren Barr leaped to power a header home after 11 minutes.
St Mirren also made it two wins out of two with a fine 2-0 victory over Motherwell.
The SPL new-boys continued their good start to the season when John Sutton produced a rare moment of quality in an otherwise dull opening period to score on 17 minutes.
The Buddies then doubled their lead in the second half when Kevin McGowne managed to squeeze a header in at the far post on 51 minutes.
Inverness Caledonian Thistle held Aberdeen to a 1-1 draw thanks to an 89th minute mistake from Dons keeper Jamie Langfield.
Stevie Crawford grabbed his second goal of the new season to put Aberdeen in front as he collected a pass from Richard Foster and finished past Mark Brown.
However the visitors claimed a last gasp equaliser to steal a share of the spoils when Langfield let the ball slip out of his grasp and fall to the feet of Barry Wilson who finished with ease.
