"It is useless to try too hard."

Translation: Je zbytečné se příliš snažit.

Why is "se" on the third position?

[VladaFu]

Because "zbytečné" is a stressed word. "Se" must be in an unstressed position. That is what the rule actually says, it is after the first stressed word, not the second word of the sentence.
