i think that sidious knew many forms of fighting, very aggressive, he killed three jedi MASTERS in seconds then engaged windu on one on, and for those of you who say windu won, its still debated that palpatine let him win. It makes good sense, palpatine might have sensed anakin comming and lost the fight so that windu would try to kill him FORCING anakin to kill windu due to his fear of losing pademe. If windu is yoda's inferiour how did an injured palpatine fight him and hold his own so well, i would gess it was a stalemate, since palpatine had to much for lightning even for yoda to just absorb yet yoda was able to cause that explosion that made them both lose. It was clearly a stalemate, Yoda even said that the battle was lost even before it hard started did he not. Dooku and Yoda are the only ones who have ever out fought mace windu in a saber battle, and dooku or tyrannus was his apprentice, if he wanted him dead he should have just killed palpatine and become the lord of the sith, thats how it works, one is the boss the other is the apprentice, the boss representing the power the apprentice wants, when the time comes, the apprentice will kill his master and take his place. vader, and dooku both wanted palpatine dead to take his place, the only one who did not wanna kill palpatine was maul and probably only because he was in sidious care most of his life. Palpatine is not the sith lord cause he is stupid he has considerable power, as well as smarts, if he didnt he would nto have been able to mess with the republic so badly.
