Anakin vs Kenobi 3

[Vader leaps onto Obi-Wan's platform. They duel.]

OBI-WAN

[aside:] Upon this platform neither shall prevail—

I shall unto the rocky shore anon

And there possess position tactical.

[Obi-Wan leaps backward onto the rocks.]

[To Vader;] 'Tis finish'd, Anakin, the triumph's mine!

Here I do claim the high ground, yea, and all

The keen advantages it offereth

VADER

You underestimate my power with the Force.

OBI-WAN

Do not attempt the jump, this I warn thee;

Thou shalt not have the legs to make the leap.

[Vader tries to leap over Obi-Wan who cuts off his legs with his lightsaber. Vader falls to the ground, slipping toward the lava.]
