Can a player score more than 2 points from battlefields per turn by holding a battlefield, retreating from it, and then scoring it again on the same turn?

Ruling: No, you cannot score more than 2 points from battlefields per turn. Each battlefield can only be scored once per turn because conquer requires the battlefield to not have been scored yet on this turn.

Nuances:

• You cannot hold a battlefield, retreat from it, and score it again on the same turn
• The limitation is explicitly stated in the rules
