A strange little side quest
Strategy Defense has plenty of company in a long tradition of players chasing timing, patterns and better decisions. Chess changed dramatically in Europe during the 15th and 16th centuries when the queen became the board's most powerful piece. The broader history adds one more wrinkle. In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. That gives Strategy Defense a little more company than it first appears to have.
