Both Leeds United and Birmingham City failed to take their first-half chances as they entered the break at Elland Road 0-0.
The two sides are in contrasting form, with Leeds unbeaten in their last six matches while Birmingham are without a win four.
It was an even first half in Yorkshire, with Lee Clark's visiting Blues having the better of the early action.
Promising winger Nathan Redmond dragged a shot wide from a good position before testing Whites stopper Paddy Kenny with another effort moments later.
The sought-after talent then set up captain Curtis Davies to send his close-range header wastefully over the crossbar.
Leeds's best efforts unsurprisingly came through Luciano Becchio, who called Blues keeper Jack Butland into action with a low shot and headed narrowly wide later in the period.
The England Under-21 international also denied Rudolph Austin and Michael Tonge as Leeds came into the ascendancy, but they could not break the deadlock before the interval.
