Why did Obi-Wan and Yoda hide. All Obi had to do was push Anakin into the lava, no Vader. Give Yoda Anakin's lightsaber and doubleteam Sidious. Their would be no way he could defeat both Yoda and Obi-Wan.
Sidious had hundreds of thousands of stormtroopers at his call. Try beating sids with hundreds of troopers shooting at you at the same time.
Read the book. Yoda says he only had one chance and that if he returned to de-throne the emperor, sids would have many troops with him. Obi-Wan could not force push his best friend into the lava. He just couldn't do it.

Yoda only had the element of surprise with him during his duel with Sidious. If Sidious knew he was still alive he would already have surrounded himself with as many available troopers as he could.
There was only one shot Yoda had to defeat Palpatine, and he blew it.
Look Obi and Yoda could have faced Sidious again. How do you think they got into the Jedi Temple? Their were a lot of Clone Troopers. Yoda would kill the troopers and Obi would have held off Sidious. Yoda would use the force to blast back dozens at a time. And Yoda could have forced pulled Sidious down making him fall a great distance and Yoda didn't he look around for the lightsaber.
Oh yeah...Yoda took the time to look for his lightsaber when there was a homicidal Sith getting ready to chop him to bits. He fled as fast as he could because he knew he could not defeat Sidious.
Obi-Wan hold off Sids? I don't think so. Sidious would have Obi-Wan down for the count within seconds, and Yoda would be faced with 100 or more Clonetroopers and Sidious at the same time. Did someone order Baked Potato topped witth chopped Green Munchikn?
Face it, Sidious won and there was no other way for the Jedi to face him again, it was a one sided battle.
Obi couldn't take Sidious? I'm sure Obi was stronger then Mace and he killed Sidious's @$$! Yoda would so kill the Clone Troopers by picking up a fighter or two and throwing it at them. If Yoda wasn't done in tome Obi would have killed Sidious. I'm sure Sidious lost his lightsaber that's why he didn't have it in ROTJ.
Mace had Sidious begging for life and don't say he was acting cause Anakin was struggling between good and evil and Sidious wouldn't have taken the risk of getting killed.
Hmmmm... I don't know about that one. Anyways, the point is there was no second chance and Obi-Wan and Yoda would not have been able to to defeat him a second time.

Whoever said that a rematch would take place where there were fighters around for Yoda to throw?
Mace got pwned by Sidious, Sids faked his defeat to help turn Anakin to the Dark Side. If Ani saw Palps kicking Mace's ass he would see the reason why Mace was fighting Palpatine in the first place.
Sure Anakin knew Palps was the Sith Lord, but he did NOT see Palpatine give reason for Mace to kick his ass. In Anakin's eyes Mace was bullying Palpatine and was going to kill an unarmed man, Anakin regretted the way he killed Dooku and he did not want Mace to do the same. That is why..."In my eyes, the Jedi are evil!"
