"I don't see reciprocality as a theory about how to win at poker. I see it as a way to see it. Reciprocality is a lens. When focused on a pair of choices, the resolution of reciprocality reveals differences large and small; it shows them as they are. When I look through the lens, I see every incremental improvement and deterioration, of mine and my opponents, at betting and everything else, as being immediately rewarded or punished in the currency of reciprocal gold. The profit is always flowing, and that motivates me."
