In a competitive environment, predicting future behaviors of opponents helps to make plans to confront their actions properly. We have used the RoboCup soccer server environment to design a coach, capable of analyzing simulated soccer games and making decisions to improve teammate players{\textquoteright} behavior during the games. We will introduce our "Opponent Pass Modeling" method which makes a model of opponent team{\textquoteright}s passing behavior to guard opponent players and as a result, to improve the defending behavior of our team. We will also describe a new approach to evaluate coach algorithms using soccer server log-files and LogCoach tool.}, doi = {10.1007/978-3-540-25940-4_50}, author = {Jafar Habibi and Hamidreza Younesy and Abbas Heydarnoori} }
