Are players required to verbally declare when they score points, and should a player be allowed to take back a pass action if they were mistaken about the opponent's point total?

Ruling: Players must verbally announce when they score points as it is a change to public information. A player cannot take back a pass action once made, even if they were mistaken about the game state. However, obfuscating public information (like hiding a point tracker behind a deck box and not announcing point changes) is a violation of tournament rules.

Sequence:

• Players must announce point changes whenever they hold/conquer a battlefield
• Players must answer truthfully when asked how many points they have
• Players should track points with pen and paper for accuracy
• Once a player passes, they cannot take back that decision

Nuances:

• Writing down points without verbally declaring them when scoring is not sufficient
• Hiding point trackers behind deck boxes while not announcing changes is unsportsmanlike and violates tournament rules about obfuscating public information
• If a player lies about or conceals point totals, they are presenting a dishonest board state
