- [Competitive Edge](https://thetavr.net/concepts/edge/): A competitive edge is an asymmetry that gives one side an outsized benefit. How edges work in zero-sum games, why they're relative and probabilistic, how they get copied, and the one question to ask before every match.
- [Gym Monster](https://thetavr.net/concepts/gym-monster/): A gym monster is a martial artist or athlete who wrecks training partners in practice but never tests it in competition. What the term means, why practice wins mislead, and how to turn practice skill into competitive results.

- [Losing Games vs Winning Games](https://thetavr.net/concepts/losing-games-vs-winning-games/): In a losing game, the player who makes fewer mistakes wins.

- [Metagame](https://thetavr.net/concepts/metagame/): The metagame is the game beyond the game. What players mean by the meta, why META is a backronym, and the bigger metagame of rules, money and politics that decides who wins in sports, BJJ and esports.

- [Value of Information](https://thetavr.net/concepts/value-of-information/): Value of information (VOI) is how much a piece of information is worth to a decision. The decision-theory meaning, the +VOI and -VOI framework competitors use to filter noise, and how players weaponize information in poker, boxing, football and esports.
- [VUCA](https://thetavr.net/concepts/vuca/): VUCA stands for volatility, uncertainty, complexity and ambiguity. Where the term comes from, what each letter means, and how competitors in boxing, MMA, chess, poker and esports create VUCA for opponents while keeping clarity for themselves.
