i dont think obi wan can win, but i think he can last longer than a few mins. going by nic gillard, obi wan is a level 8 dueler and anakin is 9, which is yodas level. guessing mace is a level 9 also, obi wan managed to last a fair while against anakin. i think it would be a fiarly similar fight with obi wan constantly giving ground and always on the defence. the major difference would be maces lack of mistakes and more caution. it would last 5-10 id say, with obi wan eventually going down. but hes perfect against guys who rely on alot of offence like grievous. obi wan will lose, but he can hold on for a bit.

Obi-Wan got alot stronger between AOTC and ROTS. In AOTC he was weaker than Kit Fisto and only on par with Jango. By ROTS he was able to defeat Grievous and considered by Mace Windu to be the Order's greatest Soresu Master.Mace takes this battle, but not without trouble. Mace is a Jedi, he's not gonna use Dark Side Force powers on Obi-Wan like Dooku did, plus he's not as strong with the Force as Dooku is. He wins, but not for a while.
Well in the Novels, just before ROTS Mace crushes Grievious's body with presumably a Force Crush, wouldn't that be considered dark?
