Lol.
Alright, let's get this straight, once again. Ehem...
1. Palpatine threw Force lightning at Yoda during the initial part of the fight, whilst doing his typical villain monologue. Now. This should've given enough time for Yoda to prepare. Yoda was nailed by the lightning and sent flying across the room, and was knocked temporarily unconscious.
2. Yoda got up and Force pushed Palpatine across the room, where he flipped over his desk. Palpatine got RIGHT BACK up. I believe his endurance is greater than Yoda. Their both old men, though.
3. Palpatine (remember, he said in the movie "all who gain power are afraid to lose it"😉 - he didn't know if he could take Yoda. So what did he do? He tried to run. Yoda was quicker to the door and confronted him. Realizing he couldn't escape - he STOOD and FOUGHT. Notice he did NOT try to escape after that.
4. Palpatine HELD OFF YODA - despite what people believe. Yoda went on the offensive. He was looking to KILL Palpatine - NOT vice versa. Palpatine was on the defensive. People make excuses "I didn't see Palpatine cut down Yoda". Well, Palps was on the defensive. Yoda was on the offensive. YODA was the one looking to cut Palpatine. And he DIDN'T!!!
5. So the fight went into the Senate Chamber. Palpatine switched to the offensive. He was chucking Senate pods left and right at Yoda. Yoda's pretty agile - and dodged them all. Then he threw one back - but had a difficult time doing so. Palpatine was laughing - notice this. At the time, he wasn't taking Yoda seriously. His mistake. Palpatine lept out of the way just as the pod closed in on him.
