We will construct K pure strategies of Player 2 such that against every sequence x of Player 1 at least K ?1 of these strategies yield a win for Player 2. The mixed strategy that puts probability 1/K on each one of these pure strategies thus guarantees a probability of at least 1 ? 1/K of winning.” ↓ We will construct K pure strategies of Player 2 such that against every sequence x of Player 1 at least K -1 of these strategies yield a win for Player 2. The mixed strategy that puts probability 1/K on each one of these pure strategies thus guarantees a probability of at least 1 - 1/K of winning.”
