It was a huge surprise to viewers when Chris decided to nominate himself to compete in a fire-making challenge against Rick Devens during Tribal Council. What made this such a shocker was Chris won immunity during the challenge prior, so he did not need to put himself in that situation. But in the end, Chris won the challenge and ultimately won the season.

Chris' move was reckless and brilliant at the same time. He already earned a spot in the final three, but knew if he had a shot at winning, he needed to get Rick out. By making this move he not only showed the jury that he's great at dominating challenges, but he also that he's a strategic player who knows how to make and execute big moves.

He knew other tribemates had clues as to the idol's whereabouts and decided to create a fake one, placing it exactly where he found the real hidden immunity idol.

Although the fake idol was never found, this was a huge strategic move and the first time someone had ever attempted to make an idol of their own. Yau-Man's decision to make the fake idol changed Survivor gameplay forever and paved the way for future players to create fake idols as well.

Feeling sorry for Fairplay, the majority of the remaining players let him and his friend win the challenge.

This was the biggest lie in Survivor history and a big strategic move. Jonny knew he had to do whatever it took to get himself further in the game, and if it wasn't for his lie, he would have never won that challenge. Fairplay outsmarted everyone on the island, including Jeff Probst, which made this move even more iconic.

During the finale of Survivor: China, Todd's speech was anything but lackluster. He laid it all out owning up to not playing a clean game, and instead lied and backstabbed to get his to the final three. His honesty impressed the jurors, which earned him the title of sole Survivor.

In order to do this, he came up with "Plan Voodoo," which was splitting the votes between Candice Woodcock and Jonathan Penner in order to flush the idol out.

Although this plan failed and Cao Boi was eliminated, "Plan Voodoo" was history in the making. Before Cook Islands, no one in Survivor history thought of such a plan. Now, almost every season since has players using this same method in order to flush a potential hidden immunity idol out, and it's all thanks to "Plan Voodoo."

Rob was one of the early players who played the game of Survivor hard. He was the first player who jumped from alliance to alliance multiple times whenever he felt it worked in his favor, or when he was in danger of getting voted out.

But what makes Rob's moves so special was that if anyone else flipped as much as he did, they would have been voted off instantly. But he knew how to play the game and how to get people to trust him all over again, even though he would vote them off the next day.
