In Praise of Strategies Johan van Benthem Abstract: Many current game logics only describe players' powers to achieve certain final outcomes. This paper surveys many different scenarios where it makes sense to also bring the strategies themselves explicitly into the logic, and it sketches the many new research problems which arise then. The text will appear in a monograph documenting the interdisciplinary 2006 NIAS project "Games, Actions, and Social Software", edited by its leaders Jan van Eijck & Rineke Verbrugge.
