Black player: building a cover story
What to do. Play the role of an independent civilian. Use real observations from the speeches of other players. Do not defend partners automatically and do not always vote with them as one block. Your story must withstand questions in the next round.
How it sounds. I suspect number 7, not out of emotion but because they called number 9 black yet voted for number 4 without explaining the change of priority.
Exercise. After two rounds, compare all the speeches of the black player and look for inconsistencies.
