Force Wise Yoda is far above Mace. A saber duel is closer, MUCH closer. But Mace himself acknowledges that he is no where near Yoda's Force mastery in Shatterpoint. Yoda takes an all out fight for sure.
Yoda. Superior duelist. Mace only defeated Palpatine via the intricate nature of Vaapad, which works primarily against dark siders. Yoda is not a dark sider.
No, sorry. It creates a "superconducting loop" of the dark side. Ergo, in order for Mace to really give into the nature of Vaapad, his opponent must be insidious and dark in nature, which Yoda is not.
No, Yoda is superior. Mace will not be able to utilize Vaapad to its fullest extent against Yoda, who is faster and knows all seven forms. He wins.
false he can use it verse yoda. actaully mace is faster. actaully yoda has not master or even study vaapad. Mace on the other hand has master every form of light saber combat.
Now that you've taken the liberty of making the claim, you now have to support it. The RotS novelization disagrees; Yoda generates no dark side energy, ergo logic concludes that the "superconducting loop" will not take place. Even though Windu will remain a master swordsman even without that advantage, he will not be able to defeat Yoda.
You need to familiarize yourself with the burden of proof. Mace does not generate speeds that surpass Yoda's, in fact, the only time that he seems to rival Yoda in terms of speed is when he is "submerged in Vaapad" which -- as we've proven -- will not take place.
Yoda has studied Vaapad, he speaks as an authority on the form in Shatterpoint. Whether or not he practices the form remains to be seen, though I will agree that there's nothing to indicate that he mastered it at all. Not that it's necessary, as Vaapad won't be mastering anyone here.
I'm afraid that Yoda wins this. His control and mastery of the Force is much greater and he has a parity with Mace as a swordsman. Windu confirms this in Dark Rendezvous when he says that he's "not Yoda's equal in peace or war" -- dueling or otherwise.
Lightsaber combat - Mace Windu was getting overwhelmed in combat by Palpatine - whom had already expended quite a bit of energy in taking out the other Jedi - before fully immersing himself in Vaapad. He would get no such advantage against Yoda, who was able to outclass the same Palpatine in saber combat and disarm him. Yoda is the clear superior here.
Force combat - Mace Windu has actually displayed greater power with the force (most notably levitating about a hundred tonnes of rock), and has no qualms with using the force lethally.
Yet, in the same book that wanks him off, Mace admits firm inferiority to the Ancient Jedi Master, though this can in part be attributed to personal bias.
Yoda also possesses experience that overshadows Mace's, and is largely acknowledged as being the most powerful Jedi of his age.
However, his ancient and frail body acts as a huge limitation, in the sense that large usages of the force tire his body out quicker than it would others, it struggles to perform such large force usages (watch the movies, Yoda's body actually shakes virtually every time he has to generate an abundance of force energies whilst in combat), and he constantly has to use the force to strengthen his body in battle.
I think it's really close, personally. The fact that Mace would have no problem with actually trying to kill Yoda by using the Force means he would be able to dictate the flow of their battle. With his Shatterpoint talent, there's nobody better at doing that than he. He would know where and when Yoda would be most vulnerable.
I'd give it to Yoda, but it's a struggle, and Mace might be able to win once every three battles or so.
