Ayoze Perez struck a late winner as Newcastle edged ever closer to Premier League survival but kept Huddersfield in peril with a 1-0 win at St James' Park
Rafa Benitez's side - once again inspired by Jonjo Shelvey - looked in danger of paying for their profligacy as Dwight Gayle spurned a string of first-half chances
But Perez belatedly made the breakthrough when he sparked and finished a move 10 minutes from time, converting Kenedy's calm cut-back to release home tension and further ease relegation fears
The slender scoreline was scant reward for a dominant display but a third successive home win in the Premier League means Newcastle climb to 12th - seven points above the drop zone - at the expense of under-par visitors who remain just three points from trouble
Benitez, who was finally able to give Islam Slimani a late cameo after injury, had admitted victory against rivals who started the afternoon just a point behind them would represent a "big step" in the survival scrap and a competitive edge in the opening stages served reminder of the cause
Jamaal Lascelles and Aaron Mooy drew early bookings, while a Kenedy penalty appeal was waved away, but Newcastle found their groove and should have made the breakthrough when Shelvey's low drive was so nearly diverted past Jonas Lossl by Gayle on the stretch (14)
The hosts continued to attack with zip, Matt Ritchie thwarted moments later from a tight angle, but the game's best chance came just before the half-hour mark when quick-thinking Shelvey lofted a free-kick that dropped onto Gayle's boot, his controlling touch not matched by the dink he sent wide
Huddersfield carried only fleeting threat on the counter, Laurent Depoitre linking well with Alex Pritchard, but further chances came Gayle's way via DeAndre Yedlin before the break, one effort well over and another improvised flick rolling the wrong side of the post
David Wagner's side mustered their first real attempt on goal with 59 minutes gone as Depoitre drilled off-target and a goalmouth scramble on 65 was emblematic of a far scrappier second period, Collin Quaner finally muscled out after Mathias Jorgensen was afforded a free header
Substitute Christian Atsu blazed a shot wide as the home side struggled for renewed inspiration, but it was from his cross that a home moment to savour came, Lossl's hand in vain as Kenedy looked up and Perez made it count
Quaner, left carelessly free as a ball was flashed across goal, and then Scott Malone had late chances to provide a final twist but a Town leveller would have been unjust, Benitez's side deservedly able to breathe easier as the games tick down
Paul Dummett defended stoutly, Mo Diame grafted tirelessly in midfield and Ayoze Perez - finally - provided the finish but Jonjo Shelvey gave further ammunition to those clamouring for an England call with another impressive display in the middle
Short, long, defence-splitting or diagonal, he crafted and stretched play once again with his passing range, even if his influence did diminish after the interval - and he shanked a couple of efforts well wide
 Gayle should have done better with the glorious ball that dropped onto his laces midway through the first half
 "Newcastle are one win away from safety
 They were brilliant in the first half; in the first 30 minutes they had 10 shots on goal
 They kept on going in the first half but in the second half they never got themselves going and Huddersfield came back into the game
 But the goal was superb and they definitely deserved to win the game
"Huddersfield have no pace but if you had said to them at the beginning of the season that after 31 games they would be outside of the relegation zone they would have been happy
" "The team was working so hard
 We had very clear chances in the first half; it was a pity we couldn't score but we were attacking and creating chances
 To win three in a row at home, the fans are delighted
 It's breathing space but not enough
 Forty points is the target so we have to carry on
" "It's a disappointing result
 It was a very good defensive performance from my players and we had the best chances in the second half
 For sure it hurts but from what I've seen - the fighting spirit and the work ethic - I have no concerns that we'll be able to collect the points we need
"Resurgent Newcastle travel to Leicester next Saturday, while Huddersfield face another of the sides who came up with them last season, Brighton, as they seek to kick-start their own fight for survival
