DeChambeau's first event as a professional was at Harbour Town Golf Links in 2016.
Poulter showed he's not done playing high-level golf with a bogey-free 64.
The 42-year-old hit four birdies to move to 13 under overall, with America's Luke List and South Korean Kim Si-woo tied for second.
Kuchar, who also started on the back nine, birdied his final two holes to join a group sitting two shots off the lead, while Huh fired a six-under 30 over an electric front nine in which he made four birdies along with an eagle at the par-five fifth.
Kraft was forced to take a drop, and he walked away from the hole with a 5. He saved par out of the bunker on the par-3 17th, rolling in a rock-solid 6-foot putt and making a routine par on the signature lighthouse hole, the 18th, to stay in front. DeChambeau pumped his fist when the ball curled in, as pleased with his improved putting as his composure at rallying late to the lead.
Second-round leader Bryson DeChambeau had the confident stride of a pending victor with his first solo 36-hole lead as a pro - at least until the third round got going.
Record cycling performance from home nations at Commonwealth Games
India has bagged 26 gold , 20 silver and 20 bronze medals during its Commonwealth games campaign in Gold Coast , Australia. India's badminton queens PV Sindhu and Saina Nehwal set up the much-anticipated women's singles summit clash on Saturday.
Seven of the Englishman's last 11 rounds have been in the 60s after having just three such showings in his first 20 rounds this season. He looked to continue his strong play at Harbour Town where he posted 10 birdies to one bogey during Wednesday's pro-am.
"I'm figuring out a lot of great things that are helping me on the golf course", he said.
"It's been a long six weeks", Poulter said. Since he switched back to that trusty flatstick, he finished t5 at the Match Play, won in Houston, made the cut at the Masters and is now -9 through two rounds at Harbour Town. Ian Poulter leads at 13 under par.
"The (Houston) win helps a lot". "I can free myself up in my mind". That's changed. "I never really thought I'd play well here, but it's kind of all come together", he said.
Poulter's passion is undeniable, but he's one of the more controversial players of this generation. He left the following three birdies over his closing stretch, including at his last two holes.
