Jumping was Anakin saying id rather die than surrender to you... so ill take my chances.. Surrendering is losing... Either way hed lost the fight.... not because he was stupid... but because Obi-Wan just outplayed him plain and simple... yes chosing the dark side was his choice... but were not talking about that... were talking about Anakins apparent stupidity in losing the fight...
Surrendering = Living. Jumping = Dying. Living > Dying. Anakin jumping wasn't him saying he'd rather live than die. "You underestimate my power!" He clearly thought that he could still win if he jumped, which was a mistake on his part.
and with the line from AOTC yes he did say Obi-wan is as powerful not that he has the potential to be.... but thing is this isnt politics where he has to explain exactly what he means... not everyone talks in black and white terms.... it may have been a perfectly reasonable implication and assumption as far as he was concerned....
And how would Anakin know what Mace and Kenobi's potentials are? No, as powerful means as powerful, Anakin isn't always right. Another example is when he says Obi-Wan's really jealous, he also says he is really ahead of Obi-Wan, in a lot of ways, and says Kenobi is holding him back. You can't expect to be abloe to twist everything Anakin says into the truth because the fact is, Anakin, especially as of AOTC, is an arrogant brat who doesn't know what he's talking about.
also if Obi-Wan and Mace have the same midi-chlorian count then thats what Anakin might mean by power... we cant just assume by power he means whose the better lightsaber duelist. This would also mean Obi-wan has the potential to be the next Mace Windu as he gets older. But in terms of wisdom the next yoda...
No, it doesn't just mean lightsaber duelist, it means everything, overall power, and, for overall power, Mace >>> AOTC Kenobi. Prove that Anakin was talking about potential when he didn't say that he was, and that he wasn't just being an idiot like he usually is.
