Chancellor Palpatine was, in truth, Darth Sidious, Sith Lord. Yoda confronted Sidious in the heart of the Senate chambers. This erupted into an intense duel between these masters of the Force, a fight that Yoda ultimately lost and was forced to flee.
Plo Koon did once. In the game The Clone Wars: Lightsaber Duels, it is mentioned by Skywalker that Plo once beat Yoda himself in a duel. "I've heard you're one of the only Jedi to have ever beaten Master Yoda in a duel."
This ensured that the Sith could hone their skills in secret without fear of betrayal from rival Sith factions. More cunning and devious than all but the most attuned Force-sensitive beings, Darth Bane could more than likely defeat Yoda in a battle of both strength and wit.

But, it was not through skill in combat. There was never any path to victory for the little Jedi. He could not murder Palpatine on the floor of the Senate without destroying any chance of restoring the Jedi Order. He could not arrest Palpatine, because he was himself a wanted outlaw and fugitive.
One of the main reasons why Yoda would've won against Anakin is simply because he was far better trained than him. Yoda could see the moves his opponents were going to make before they made them; therefore, battling against Anakin would've put him at a far heavier advantage.
As powerful as Darth Sidious may have been, it's easy to forget he actually seemed afraid of Master Yoda. As seen in Revenge of the Sith, Palpatine initially thought he could deal with the aged Jedi Master - and then, when Yoda proved able to counter the Sith Lord's Force lightning, he fled.
Neither lightsabers nor the Force could help Yoda defeat Darth Sidious. Though Yoda was able to keep his adversary on his toes, he was unable to end the conflict, and their duel ended with no clear victor.
Aside from agility and telekinesis, Yoda could absorb and redirect Force attacks, like lightning. Because of his higher understanding, he would easily overcome Darth Vader in a fight, though that doesn't mean it wouldn't be a difficult battle.
Jedi Master Yoda is the most powerful of them all. This should come as no surprise, as he was the head of the Jedi Order in the prequels and was revered for his abilities during the original trilogy. Yoda's power is unmatched and was a real threat to Darth Vader and the Imperials.
Yoda's Lightsaber Form Hints He Was Vulnerable To The Dark Side - IMDb. With the various forms of lightsaber combat in the Star Wars universe, the form that Master Yoda employs suggests of a possible weakness to the dark side's sway.
But why did he seemingly give up and never help the Rebellion? Yoda still stands as one of the most powerful characters in Star Wars, yet even he couldn't defeat Palpatine. After their battle in Revenge of the Sith, Yoda felt beaten and fled into exile on Dagobah, where he hid away for 19 years.
Evidence for ROTS Anakin > Yoda (in the force)
Sidious then confirms that Anakin is 'far' more powerful. Anakin's quick work of Dooku + Sheev's confirmation immediately make it clear that Anakin is a tier above Dooku power wise when he cuts loose.
In Legends, Luke Skywalker was the undisputed most powerful Jedi to have ever lived in our knowledge, surpassing Yoda.
Yoda was a legendary member of the Jedi Council as a Grand Master of the Jedi Order and member of a mysterious species capable of living for centuries. He was stronger than most in a connection to the Force and though he was small in size, he'd been so powerful and wise having had trained Jedi for several centuries.
Master Yoda failed Anakin Skywalker in Star Wars: Episode II — Attack of the Clones, and it resulted in the destruction of the Jedi Order. Master Yoda is one of the most revered characters in the Star Wars universe, and for good reason, but he ultimately failed in stopping the rise of the Sith.

At some point, Yoda took on a human named Kantam Sy as his Padawan. The two were stationed at the Jedi Temple on the planet Endovar.
Emperor Palpatine
He's such a major force hanging over all of Star Wars, in fact, that he was ultimately brought back in Rise of Skywalker. His status as a supreme villain comes in large part from his immense power, which at times seems to be almost unlimited.
throughout many of the Legends storylines, Vader sought to hunt down every last Jedi. while Palpatine was no longer concerned with the Jedi. Order, in his eyes, Yoda and the Jedi no longer posed a threat to his role. during the early years of the Empire, Palpatine only sent Vader to hunt survivors.
Young Anakin Skywalker is put before the Jedi Council to determine if he should be trained, though Yoda senses great fear in the boy.
Arguably, Qui-Gon is wiser in some ways, given that he knows how to preserve his consciousness in death. Yoda is wise, but sometimes flawed, given that some of his views align with the problematic thinking of the Jedi of this era.
