Hibernian boss Colin Calderwood bemoaned his side's inability to see the game out after they suffered a late 1-0 defeat to rivals Hearts at Tynecastle.
Kevin Kyle headed in an 86th-minute cross from substitute Arvydas Novikovas as Hearts broke down stubborn Hibs resistance to claim a 10th win from 12 games.
The defeat was Calderwood's seventh loss in 11 games in charge since succeeding John Hughes as boss in October. But he conceded his side were second best and praised the goal.
He said: "You've got to go the full length (of the game). It is frustrating. It was our throw-in in the last third and they went quickly up the pitch and scored.
"It was terrific quality, first with the dribble, then with the cross and the header at the back stick. Sometimes that quality decides a tight game.
"But they were certainly in the ascendancy and we were living for one or two breaks."
