Chicago ? This time, Shaquille O’Neal had nothing but praise for the opponent and the officiating.

Chicago's Kirk Hinrich, left, and Luol Dent, right, celebrate as Ben Gordon, center, watches play. The Bulls defeated the Miami Heat, 107-89, Tuesday in Chicago.

The only finger he pointed was at himself.

He realizes he needs to do more if the Miami Heat are going to climb out of another 2-0 playoff deficit. Dwyane Wade needs to step up, too.

Ben Gordon scored 27 points, and Luol Deng added 26 to lead the Chicago Bulls to a 107-89 victory Tuesday night and a 2-0 lead over the defending champions in this first-round series.

“I have been around a long time, and I’ve been in all these situations before,” O’Neal said. “Basically, the Bulls did what they’re supposed to do and protect their home court. We have to play smarter basketball. We got to come with a lot more energy and play with a lot more effort and a lot more passion.”

Gordon scored 11 in the third quarter, hitting three three-pointers, and the Bulls built a 17-point lead. Deng scored 14 in the fourth as Chicago sent Miami halfway to elimination.

O’Neal accused the Bulls of flopping and lashed out at referee Eddie F. Rush after Game 1, but said it was a “perfect game today” for the officials. It was anything but that for the Heat and their superstars.

O’Neal and Wade had subpar performances again after struggling through foul trouble in the opener, finishing with 17 and 21 points, respectively. O’Neal was just 6-for-14 from the floor with eight rebounds. Wade, who led a late charge in Game 1, never really got going, hitting 9-of-19. And both had seven turnovers.

“We really can’t make any excuses tonight,” O’Neal said. “It was a well played game. They just outplayed us. I had way too many turnovers. They shot the ball extremely well.”

Trailing 85-71 through three quarters, the Heat were within seven after Wade’s layup early in the fourth, but they had no answer for Deng. Quiet in the first half after scoring 33 in the opener, Deng scored the Bulls’ first eight points in the fourth before Thabo Sefolosha hit a jumper that made it 95-82 midway through the quarter.

The best-of-seven series shifts to Miami for two games, with Game 3 Friday night.

“We’ve been here before, you know what I’m saying?” Miami’s Alonzo Mourning said. “I have the utmost confidence in my teammates and this team that we can pick ourselves back up and get back on track.”

Home teams that have taken the first two games in a best-of-seven series have gone on to advance 95 percent of the time, but the Heat and Bulls have bucked that trend in recent seasons.

Miami dropped the first two games at Dallas in last year’s finals, then won four straight to capture the championship. Two years ago, the Bulls opened with two wins at home over Washington but lost the next four in their first playoff appearance since the Michael Jordan-Scottie Pippen era.

“We’ve got to be mature enough to understand that Miami has been in this situation,” said Deng, who was 2-of-7 with six points in the first half. “We can’t relax. We have to keep playing aggressive.”

The Bulls fell into this matchup when they lost the season finale to New Jersey and dropped from the second seed to fifth. But what looked like trouble for them has, so far, looked rather easy.

As they did in Game 1, the Bulls beat the Heat with quick passes that led to open looks. They were 43-for-78 overall and 11-of-17 on three-pointers after shooting an uncharacteristic 3-for-17 from long range in the opener.
