At the Nomination Ceremony, Enzo, a 42-year-old insurance adjuster from Bayonne, NJ who previously competed on Big Brother Season 12, decided to put Nicole, a 29-year-old social media influencer from Ubly, MI who previously competed on Big Brother Seasons 16 and 18, and Christmas, a 38-year-old fitness entrepreneur from Raleigh, NC who originally competed on Big Brother Season 19, on the chopping block heading into the Power of Veto competition that will ultimately determine this All-Stars season's Final 3 houseguests.

Enzo won the Head of Household competition dubbed "Knight Moves," which required Enzo, Christmas and Cody Calafiore, a 29-year-old soccer coach from Howell, NJ who originally competed on Big Brother Season 16, essentially play a game of chess.

The players had to strategically move themselves around a giant chessboard in attempt to trap their opponents.

"You can only move like a knight in chess -- one square vertically and two squares horizontally or two squares vertically and one square horizontally," explained Nicole, who was deemed ineligible to compete as the outgoing HoH.

"Once you land on a square, that square is now out of play. That means no one can land on that square again. Run out of moves and you're out of the game."

The last player standing would become the season's next Head of Household.

Nicole thought Enzo winning HoH would be her best bet to advance in the game because with only four people left in the game, only one person will be voting to evict this week.

With that being said, Nicole believed both Cody and Christmas would keep her safe and take her to the Final 3.

Cody wanted to prevent Christmas from winning HoH, and in turn, Christmas was hoping to win so she could evict Cody this week. Christmas hoped she and Enzo could work together to corner Cody so he couldn't win the HoH competition.

But Cody was hoping for the same thing, that Enzo would be his ally in the competition to take Christmas out.

In order not to disappoint either Cody or Christmas, Enzo's strategy was just to stay out of it and let the two competitors go at each other. Cody caught on at one point that Enzo wasn't helping him to trap Christmas and he'd have to take one for the team.

Nicole could also tell that Enzo wasn't going after Christmas and he was "just looking out for himself," which she called "very frustrating." Nicole said Enzo didn't seem to care about Cody or herself and she was seeing Enzo's true colors.

More than halfway through the competition, Christmas realized she was working solo.

Cody vented how he and Enzo were supposed to work together but Enzo just tried to set himself up with multiple moves on the opposite side of the board.

Cody sacrificed himself so Christmas would only have one move left, and in the end, Enzo was crowned the Final 4 HoH.

Cody said Christmas has to go home this week without a doubt.

As for Nicole, she said she was mad and no longer trusted Enzo, and Cody hoped allowing Enzo to win wouldn't come back to bite him in the butt.

Cody wondered whether Enzo just didn't know what he was doing the competition and wanted to give him the benefit of the doubt, but Nicole gave Enzo more credit than that.

Enzo told the cameras he was considering nominating Cody for eviction to break his streak of never having been on the chopping block before. Enzo wanted to be the only person in the game with that statistic.

Enzo revealed his dream Final 3 was with Cody and Christmas, and he told Cody they should get rid of Nicole because she would take Christmas to the end over one of them.

Enzo also considered Nicole to be a better player than Christmas because she's already won Big Brother once before.

At the Nomination Ceremony, Enzo announced he had decided to nominate Nicole and Christmas for eviction although he liked the both of them. Enzo advised them to fight in the Power of Veto competition.

Nicole, Cody and Christmas acknowledged the Power of Veto would be so powerful and they all needed to win it. Christmas cried, saying it was three against one and so she needed to save herself.

The winner of the Power of Veto will get to decide who joins Enzo and him or herself in the Final 3.
