What form of play does King Oil and Personal Preference have in common?
King Oil King Oil is a board game by Milton Bradley, created in 1974 and now long out-of-print. The game requires players to drill for oil on a three-dimensional board, acquiring property and wealth.
King walk In chess, a king walk, also known as a king march, steel king (Dutch: wandelkoning , literally "wanderking") or fighting king, refers to occasions where the king travels up the board, often involved in a mating attack against the opposing king. This is a highly unusual occurrence since the safety of the king is considered paramount, and players are recommended to keep the king out of harm's way, at least until the endgame. Nevertheless, in contrast Wilhelm Steinitz, often known as the father of modern chess, was renowned for his maxim that "the king is a fighting piece". Dutch chess historian and author Tim Krabbé has documented over one hundred such games.
