  • 7. Complexity & the game of Go "Chess lies on the boundary between  the tasks best accomplished by careful  co‐ordination and design – the  strengths of planning – and those best  accomplished by experiment and  adaptation – the strengths of  markets." ‐ John Kay, Economist
  • 8. Complexity & the game of Go Chess Go • 8 x 8 board • 19 x 19 board • Play in squares • Play on lines • Kings, Queens, Bishops,  • Black stones and White  Rooks… stones • Aim: to kill the other  • Aim: to surround more  players King territory • 1st 3 moves = 4,352 • 1st 3 moves = 46,655,640

  • 10. History of Go • Played by the nobles • Generals practiced it for war • Simple = Pure Strategy • Cultured = Calligraphy + Archery + Haiku + Go • Taught in 5 Schools
  • 11. Basic Rules • Start with a small, empty  board  • Each player takes a turn  placing one stone  4 3 anywhere on the board • Each stone has liberties 2 1 • When a stone has no  more liberties it is  captured and taken from  the board
  • 12. Basic Rules • When two stones are  placed next to each other  they form an army • An army has to lose ALL its  liberties to be captured • The bigger an army is, the  stronger it is • Whoever surrounds the  most intersections wins the  game
  • 13. Practice Games
  • 14. Some hints to get started 1. Don’t start near  the edge 2. Place fence posts  7 1 then the palings 8 2 3 3. Surround as  1 3 4 5 much area as  2 6 possible 1 2 4. Try not to play up  against the other  player White Black will win will win

  • 18. Influence & Future Constraint The famous ear‐reddening game – 1846 Inseki v Shusaku
  • 19. Influence & Future Constraint Why is move 127 so powerful?  It strongly influences many possible future moves
  • 20. Complicated v Complex Complicated Complex More constrained Less constrained Stable Unstable Similar input = similar output Small changes => unpredictable results Manage results Manage boundaries & attractors Set Objectives Set Outcomes Break down to details Chunk up & experiment Apply Best Practice Use Safe‐Fail to discover what works Dave Gray, Founder XPLANE > “When you make the complicated simple, you make it better. But when you make the complex simple, you make it wrong.”
