The tables
Play one, and it stops being theory.
0/8 shapes named
Eight matrices you can actually sit down at. Name the shape before you play it, then play real rounds against an opponent running a real named strategy — tit for tat, grim trigger, a pattern reader, a calculator that sees your move before it answers.
The equilibrium outlined on each matrix is computed from the payoffs every time it is drawn, so it cannot drift away from what the debrief claims about it.
