A Resolution of a Question

Another one from when I was 18, this one is about what I consider one of the most perfect movie scenes ever shot, from Akira Kurosawa's The Seven Samurai.

Two samurai face each other.
One defends, the other prepares to charge.
"It will be a tie!" cries an onlooker.
Sword by side, the defender steels
As the charger raises his blade, shouting.
The charger rushes forward.
The charger falls before he knows he is cut in two by the defender's sword.
The defender remains steeled for a moment.
Then, he wipes clean his sword, sheaths it
And walks away.
