Korver scored eight straight Chicago points to keep the Bulls in the game, then the Bulls reeled off the last 10 points of the second quarter to gain the momentum heading into the break.
"Kyle taking those shots, we'll live with that all day," Bulls center Joakim Noah said. "Kyle getting an open look, there is no better offense than that in the whole NBA."
Luol Deng hit a wide-open 3 after an offensive rebound by Noah, cutting the Orlando lead to single digits for the first time since midway through the first quarter.
Nelson threw away a pass and Rose hit a running 3 as the half expired, drawing Chicago within 57-52.
In the third quarter, Boozer capped an 8-2 run with a short jumper that gave Chicago its first lead of the game. Orlando responded with a 13-4 run to end the quarter, the last six of its points coming on back-to-back Richardson 3-pointers.
The nation grieved for those hurt, killed and affected by the Boston Marathon bombings. After one of the suspects was caught on Friday — following a day-long lockdown and manhunt — sports returned to Boston over the weekend.
"We tried to run them off their spots," Rose said. "But they're a team who doesn't care if you contest their 3s. They will shoot them anyway."
Orlando led by 10 early in the fourth quarter before Chicago tied the game with a nine-point run. Boozer scored eight points in the first three minutes of the quarter.
That set up the furious finish.
"Our guys gave up the lead and then hung in there and fought real hard," Van Gundy said. "It was a great win to beat them. The best team in the league."
NOTES: The Bulls played without guards Richard Hamilton (right shoulder contusion) and C.J. Watson (left ankle sprain). Hamilton has missed 25 of Chicago's 41 games this season because of injuries, while Watson sat out for a third straight game. No timetable was given for either player's return, though Thibodeau said Watson is "getting close."... Thursday's game was the first of a tough four-game stretch for Orlando leading into next Thursday's trade deadline. After playing the Bulls, the Magic have home games against Indiana and Miami, then a road game at San Antonio. . Richardson had to leave the game late in the fourth quarter after banging knees with Nelson and spraining his left ankle. He limped down the corridor after the game on his way to get an X-ray, which was negative.
PBT: The Pacers defeated the Heat 97-93 in Game 2 to even the series at 1-1, which now shifts to Indiana.

DPS: Dan Patrick talks about Phil Jackson's comments about starting a team with Bill Russell now because of his championships and brings up the great question of, if it's all about championships, how come we don't talk about guys like Sam Jones, Frank Ramsey or John Havlicek who all have multiple rings?
