“Nope. No Revolutionaries Here. We’re Playing Chess.”

Two thousand years ago, the Maccabees hid in caves plotting to overthrow the Greeks in Palestine. To hide the purpose of their meetings, they had a spinning top available. When the Greeks came knocking, they simply pretended that they were only gathered to play a game of dreidel.

Today, political rallies are outlawed in Armenia. So masses of protesters gather together with chess boards in the capital, Yerevan. When the police come knocking, they simply say that they’re playing chess.
