Hearts missed the chance to leapfrog Rangers into second place in the Scottish Premier League as Aberdeen held them to a goalless draw.
The sides cancelled each other out as both were denied their third league win in a row. The high-flying Jam Tarts had goalkeeper Marian Kello to thank for earning them a point as he superbly stopped Sone Aluko's shot before denying Rory McArdle and Chris Maguire.
Rudi Skacel had come close for Hearts after the break but it was the Dons who looked the likelier to win with Ryan Jack missing a good chance and Nick Blackman having a powerful effort tipped over in stoppage time. The point means Hearts are just one point behind Rangers, although the Glasgow giants have three games in hand.
Hibernian remain in tenth place despite recording their fourth consecutive league win for the first time since 2008 with a 2-0 defeat of Inverness Caledonian Thistle. Victor Palsson's header was cleared off the line by Russell Duncan in the first half before Callum Booth found the net with a stunning strike into the top corner just on the hour mark.
Ross Tokely missed a good chance to level for the highlanders before Lewis Stevenson scored his first-ever goal on his 104th appearance courtesy of a deflection a minute before the end.
Kilmarnock got back to winning ways as they dispatched second-from-bottom St Mirren 2-0 at Rugby Park. Mixu Paatelainen's side had been thrashed 5-0 by Aberdeen last weekend but took just 13 minutes to open the scoring against St Mirren as former Le Havre youth striker William Gros netted on his first start for the club.
The French youngster then turned provider as Alexei Eremenko picked up his pass and his drive from 20 yards bounced in front of Paul Gallacher and over the goalkeeper's head to double the lead after 30 minutes.
St Mirren's Kenny McLean struck a post after the break and a Darren McGregor header was cleared off the Killie line but the home side held on to move five points clear of Motherwell in fourth place.
Andis Shala scored late on for Dundee United to deny Hamilton their first home win of the season. Mickael Antoine-Curier converted a penalty on 33 minutes after Gavin Skelton had been brought down by Prince Buaben in the box.
David Goodwillie, Johnny Russell and David Robertson all spurned close-range chances for United but it was substitute Shala who came to their rescue when he steered in an impressive header from Craig Conway's delivery in the 83rd minute. Goodwillie had a late chance to win it for United but Hamilton claimed a point that leaves them seven adrift at the bottom.
