If a player scored both battlefields on their turn and retreated to base, then on their opponent's turn they use Ride the Wind to move to an empty battlefield, do they score that battlefield?

Ruling: Yes, the player can score the battlefield on their opponent's turn. If you gain control of a battlefield you did not score that turn, you score it.

Nuances:

• It is possible to start an opponent's turn while controlling a battlefield and score that same battlefield during that turn, since you haven't already scored it that turn.
