Consider concurrent, infinite duration, two-player win/lose games played on graphs. If the winning condition satisfies some simple requirement, existence of Player 1 winning (finite-memory) strategies is equivalent to existence of winning (finite-memory) strategies in finitely many derived one-player games. Several classical winning conditions satisfy this simple requirement. Under an additional requirement on the winning condition, non-existence of Player 1 winning strategies from all vertices is equivalent to existence of Player 1 stochastic strategies winning almost surely from all vertices. Only few classical winning conditions satisfy this additional requirement, but a fairness variant of omega-regular languages does.
