Brentford held second-placed Leeds United to a 1-1 draw at their Elland Road fortress.
And the home side - who have lost only one league game at headquarters this season - were indebted to a Jermaine Beckford goal for salvaging them a point.
The Bees lead through a Ben Strevens goal - although Charlie MacDonald may try to claim it - and looked at one stage as if they would take all three points.
But the predatory Beckford grabbed Leeds a share of the spoils.
As would be expected, the promotion-chasing hosts started quickly and created all the chances in the early stages.
Wojciech Szczesny tipped a curling Robert Snodgrass free kick round the post and Gary McSheffrey lofted an effort narrowly over.
Luciano Becchio tried to chip Szczesny but over hit his effort and the Argentinian headed wide soon after.
Whilst Leeds were having the better of the possession, Brentford - with their two solid banks of four in defence and midfield - were proving hard to break down.
Beckford flicked a McSheffrey cross wide just past the quarter hour but the game soon stagnated with The Bees frustrating their hosts.
And on the half hour the visitors should have gone ahead - Toumani Diagouraga was the architect, bursting through midfield and feeding Sam Wood, after picking up a ricochet, the midfield man cut in off the right and tried to lift it over Casper Ankergren but the goalkeeper stuck out an arm and turned it away.
The Bees grew in confidence and started committing a few more men forward, but that left gaps and Leeds were able to create openings.
Beckford headed narrowly over before Snodgrass - who provided that chance - lashed over.
Szczesny was forced into a low save from a dribbling Beckford effort and Mark Phillips, who excelled in an unfamiliar right back position, deflected another shot from the striker narrowly wide.
McSheffrey shot just over and Tommy Smith made a fantastic block with his face from a fierce Snodgrass effort after the wide man cut inside Ryan Dickson.
The second half started in a similar manner to the first - with Leeds on top and Beckford looking the man most likely to break the deadlock.
Leeds' top scorer had a weak volley saved b y Szczesny and then curled an effort straight at the Polish goalkeeper from 20 yards.
The ever-lively Beckford flicked a header across the face of goal - with Snodgrass and Becchio unable to turn it home - before Brentford shocked their hosts by taking the lead.
Kevin O'Connor curled in a corner - won by Weston, who was starting to worry the promotion-chasers - Leon Legge headed down, Charlie MacDonald fired and turned in a shot that was saved by Ankergren but Strevens was there to turn it home, albeit he might not have known much about it.
There might have been a debate about whether the initial shot from MacDonald had crossed the line but The Bees players engulfed Strevens in celebration.
The goal opened the game up and Leeds threw everything forward in search of a leveller.
Snodgrass curled an effort narrowly wide, Beckford missed the target with a header and Szczesny was forced to turn a flicked header from Legge round the post to prevent an own goal.
Szczesny blocked a Beckford volley and the same man headed wide soon after.
Leeds attacking left spaces for The Bees - Wood found room inside the box and rounded Ankergren but was forced wide and the chance was gone.
Weston, who was establishing himself as Brentford's main threat, created another opening for Wood but his header was blocked by Patrick Kisnorbo.
Leeds got their leveller when it was starting to look like Brentford had weathered the storm.
Snodgrass put in a cross that reached McSheffrey at the far post - he turned it back across where Beckford was waiting to turn it in from close range.
The Bees should have got their noses back in front moments later through a breakaway goal.
MacDonald lead the break, finding space twenty yards out after a good run, he tried to feed Weston but the pass was intercepted - the ball, however, broke back to him and he flashed a shot inches wide.
Diagouraga had a shot blocked as The Bees aimed to prove it was not only Leeds who wanted to win but Snodgrass should have scored when he raced through moments later, only to be forced wide by the presence of Dickson and waste the chance.
O'Connor produced a fine block to deny Jonathan Howson and Lubomir Michalik had a header saved as Leeds pressed.
And they came within a whisker of a winner when a Bradley Johnson cross was headed against the post by the towering Michalik.
MacDonald had a shot saved after a nice turn and Carl Cort blocked a Michalik volley at the other end as both teams searched for a winner.
But it would not come and they had to settled for a point a piece.
