If you have enough points to win on your turn, but only by including your unrevealed VP development cards, are you forced to win?
E.g. I have three cities (6 VP), three settlements (3 VP), and I buy a development card, which ends up being a victory point card. Can I wait until my next turn where I believe I'll have a chance to steal longest road, and end the game on 12 VP, or do I need to declare victory now?
The reason why I ask is that we keep a running total of stats from the games we've played over the years, and finishing on a higher total would bring up my average VP per game score.
