Kilmarnock and Inverness had to settle for a share of the spoils at Rugby Park but the visitors will rue a number of missed opportunities.
Craig Drago scored against his former club
Colin Nish headed Kilmarnock into an early lead when he powered in a corner kick from David Fernandez.
But Craig Dargo hit back to haunt his old side when squeezed in an equalising goal from an acute angle.
After the break Dargo went close with a header and an acrobatic volley before hitting the post from just three yards.
The game kicked off after a minute's silence for former Killie manager Walter McCrae, who died on Friday.
Ian Black was inches over with a 20-yard strike after a short corner caught the home side napping.
Killie striker Gary Wales then came close in the fifth minute but his first-time strike after a great Nish lay-off was deflected just over the crossbar.
Nish gave Killie the lead in the seventh minute when he threw himself at David Fernandez's deep corner to head home from close range.
Allan Johnston was wide with a 20-yard drive but former Killie striker Dargo stunned the home support with a 19th-minute leveller.
A long throw was headed towards the far post by Darren Dods and Dargo flicked it past Graeme Smith into the roof of the net from a very tight angle.
Killie defender Frazer Wright almost repeated his match-winning strike against Livingston but saw his 25-yard free-kick just clear the Inverness goal.
Striker Graham Bayne headed wide from 12 yards and Dargo headed just over from Ross Tokely's far-post cross as the visitors pressed after the interval.
A brilliant cross by John Rankin saw 'keeper Smith and Grant Murray go for the same ball, but Dargo's acrobatic attempt flew past after the defender had headed clear.
As the game entered the final 20 minutes, Dargo was guilty of an incredible miss.
Smith was unable to hold Richie Hart's low drive and the striker pounced on the rebound - but hit the post.
Killie soon created their best chance of the half when Wales ran to the byline and cut it back for Fernandez, but Richard Hastings produced a magnificent block.
Inverness looked the likelier winners but both sides had chances to win it in injury-time.
Caley 'keeper Mark Brown brilliantly pushed Wright's header away before Inverness sub Iain Campbell raced clear but saw a low shot smothered by Smith.
