12) In chess, the side with the white chess pieces always takes the first turn and thus has an unfair advantage. This demonstrates inequality in our society. Inequality is also seen in The Tempest, as Prospero has power over everyone on the island. Caliban, in particular, is affected by inequality as he is treated as nothing more than a slave. This translates to the real world as world leaders and the super-rich have ridiculous amounts of power compared to the "regular" people of the world.
11) Chess requires control. You need control in order to make the correct decisions and, in turn, achieve victory. If you panic, you lose control, and that might lead to making stupid mistakes. This also translates into real life. Having a certain degree of control can help us plan our next steps in life. Control is also seen in The Tempest. Prospero seemingly controls every situation on the island. This is so that his plan of revenge can be fulfilled.
