The Risky Decision (3年後の賭け, Sannengo no Kake; lit. "A Three Year Gamble") is the three hundred thirty-sixth chapter of the Dragon Ball manga. This chapter's anime counterparts are the episodes "Goku's Special Technique" and "Z Warriors Prepare".
With the Z Fighters having made their decision to train for the battle with the androids, Vegeta asks Goku how he escaped from Namek. Yamcha recalls King Kai saying that Frieza's spaceship would not work. Goku says that he found five space pods nearby, which Vegeta realizes belonged to the Ginyu Force. Goku says that the pod took him to Yardrat, which Vegeta says the Ginyu Force were set to conquer next. Goku even told them that the people of Yardrat were really friendly, they gave him an outfit identitcal to the one they wear. Vegeta says that the people of Yardrat have strange techniques, and that Goku would not have left without learning one. Goku confirms this idea, and claims that he has learned teleportation.
To prove the truth of his claim, Goku teleports to Kame House and takes Master Roshi's sunglasses and then returns, amazing the rest of the group. Tien Shinhan asks where and when they should reconvene in three years. Goku does not remember, but Piccolo informs the group, saying that they should meet an hour early. Piccolo says that anyone who does not think they stand a chance should not come, which Vegeta says applies to Piccolo. Bulma defuses the situation by suggesting they attack Dr. Gero right away by asking Shenron for his location. Krillin likes the idea, but Vegeta promises to kill Bulma if she does so. Goku says that he wants to fight as well, and so does Tien. Even Krillin then agrees, saying that a common enemy will keep Vegeta at bay. Bulma is aghast at their decision. The group then splits up to train. Goku, Piccolo, and Gohan decide to train together, as do Tien and Chiaotzu, while Krillin and Yamcha opt to train with Master Roshi. Vegeta claims that he will also become a Super Saiyan before flying off. Goku tells Bulma to take care of the baby, which Yamcha interprets as Goku hinting that the two of them should marry and start a family.
At Capsule Corporation, Vegeta asks Dr. Brief to build him a 300G training room. Goku then tries to convince Chi-Chi to let Gohan train instead of study. Chi-Chi angrily refuses, and Goku "accidentally" knocks her through a wall and outside while "patting her on the back". Chi-Chi then reluctantly agrees, but makes Goku promise to quit martial arts after the battle and Piccolo believes this is one battle that Goku will not survive in it. Vegeta, inside his training room, vows to surpass even the Super Saiyan level. The chapter then skips ahead three years, and Goku, Gohan, and Piccolo fly off to meet the androids on the day that Trunks claimed they would arrive.
