If someone Hidden Blades a Yasuo at a battlefield, can the Yasuo player use Ride the Wind to prevent Hidden Blade from going off on him?

No, the Yasuo player cannot use Ride the Wind to prevent Hidden Blade from resolving.

The Reasoning

1. Action vs. Reaction: Ride the Wind is an [Action] spell. According to Rule 158.2.a and RiftJudge FAQ #9557, [Action] spells can only be played during an Open State (when no chain exists) to start a new chain. They cannot be added to an existing chain.
2. Closed State: Once your opponent plays Hidden Blade, it is placed on the chain, and the game state becomes "Closed." In a Closed State, only cards with the [Reaction] keyword can be added to the chain to respond to existing items (Rule 338.1.a.1, Rule 813.1.c.1).
3. Hidden Keyword Exception: While cards played from the "Hidden" zone gain the [Reaction] keyword, Ride the Wind does not have the Hidden keyword, nor is it being played from the Hidden zone. Therefore, it does not gain the ability to respond to the chain and remains strictly an [Action] spell.

Because you cannot play Ride the Wind in response to Hidden Blade, you cannot use it to move your unit to a different location to make it an illegal target for the spell. Hidden Blade will resolve successfully, killing the Yasuo.
