New players hear 'blind pass' and assume it is a mistake or a dare. It is neither. It is a specific, legal option inside the Charleston, and knowing when to use it is a small edge that costs nothing to learn.
What a blind pass actually is
During the Charleston you pass three tiles at a time. A blind pass means passing along tiles you received without looking at them, or passing fewer of your own tiles than three and filling the rest from what was just handed to you, unseen.
The tiles move on without ever entering your hand. You never learn what they were, and neither does the table.
When it is legal
Blind passing is permitted on the second and third passes of the first Charleston, not the first pass. Convention varies slightly between groups on the second Charleston, so ask at a new table rather than assuming.
It is never permitted on the courtesy pass at the end, which is a mutually agreed swap of an equal number of tiles, both players looking.
Why anyone would do it
Because you already have what you need. If your hand is committed and none of the incoming tiles could plausibly help, taking three unknown tiles into your rack means sorting them, evaluating them, and passing three away again, all of which risks passing something you actually wanted.
It is also a tempo move. A blind pass is fast, and in a group that plays briskly, a player who blind passes a settled hand keeps the Charleston moving.
The cost
You give up information and you give up an option. Any of those unseen tiles could be the joker or the pair tile that changes your hand's direction entirely, and you will never know.
That is why blind passing is a late-Charleston move for a settled hand, not an early one. Passing blind before you know where your hand is going is just gambling with your own deal.
A simple rule
If you can name the card section you are building toward and you are only missing tiles of a specific kind, a blind pass is safe and efficient. If you are still choosing between two directions, look at everything, every time.
That decision, whether your hand is settled enough to stop looking, is exactly the judgment the coach makes explicit when it reads a hand: not just which tile, but whether the hand has committed yet.
