A Student Asked Teuber

A student asked Teuber: How shall I play Settlers of Catan?

Teuber answered: Be like the robber. The robber receives from all players. The robber opposes the leader. The robber neither wins nor loses any game, but plays every game.

Another student asked Teuber: How shall I play Settlers of Catan?

Teuber answered: Be not like the robber. The robber always starts in the same position. The robber does not utilize his resources. The robber does not try to win.

A third student asked: How can one be like the robber and not be like the robber?

Teuber answered: How can one be like a student, and not be like a student?
