best or the best

[Nordre]

Dear teachers,

When do we use best (superlatives) without the?

"You know best when to buy a new computer."

or

"You know the best when to buy a new computer."

Thank you.

We often use superlatives before possessive adjectives such as my/your/her, etc.

my biggest fear
your best feature
her worst nightmare
