Dundee United and Kilmarnock shared a goal apiece within a minute and had to settle for a point each after an exciting tussle at Tannadice.
Conor Sammon drilled the ball home to break the deadlock on 22 minutes after a Mehdi Taouil through ball.
But Johnny Russell was quickest to respond to Prince Buaben's clever pass and equalised within 60 seconds.
Sammon and Alexei Eremenko went close for Killie after the break, while Jon Daly missed a late chance for United.
But, although it was the second game in a row that they have failed to win at home, the draw leaves United a point ahead of Kilmarnock in sixth place in the Scottish Premier League.
Russell had taken Danny Cadamarteri's place up front, with Barry Douglas in midfield instead of David Robertson, as United manager Peter Houston responded to the surprise midweek home defeat by St Mirren.
Sammon put Kilmarnock in the lead at Tannadice
And, as United exerted the early pressure, the young striker and Garry Kenneth both might have done better with headers that failed to find the target.
Kilmarnock were unchanged after three consecutive 3-0 victories and defender Frazer Wright, who had survived a late fitness test, bulleted home a header from a corner after 15 minutes only for the goal to be disallowed for a foul by Sammon.
United were dominating possession, but it was the visitors who took the lead when Taouil turned away from his marker and set up Sammon for a fine finish.
However, the lead lasted less than a minute, Buaben setting up Russell to score.
Sammon and Eremenko forced a couple of fine saves from Dusan Pernis, the latter Kilmarnock man's lovely free-kick being touched on to the post by the goalkeeper's outstretched hand.
David Goodwillie had a header deflected wide at the other end as United were forced to introduce 18-year-old Stuart Armstrong into midfield in place of the injured Scott Robertson.
Goodwillie sent another effort just over the crossbar as an exciting first half drew to a close and the latest addition to the Scotland squad became ever more influential.
Eremenko was the Kilmarnock player in the spotlight at the start of the second half, being booked for simulation following a challenge by Kenneth then firing an effort into the side-netting.
Russell fired wide and Bell was forced to tip a long-range drive from Goodwillie over the crossbar as United responded.
Kilmarnock remained dangerous on the break and United were relieved to see an Eremenko drive squirm just wide after taking a deflection and, from the corner, Manuel Pascali headed wide.
Both sides pressed for a late winner, but a Daly effort was well saved by Killie's Cammy Bell and another good chance squandered by the striker was the closest either side came as the match ended all square.
