  Soccer Simulation 2D League is one of the major leagues of RoboCup
competitions. In a Soccer Simulation 2D (SS2D) game, two teams of 11 players
and one coach compete against each other. The players are only allowed to
communicate with the server that is called Soccer Simulation Server. This paper
introduces the previous and current research of the CYRUS soccer simulation
team, the champion of RoboCup 2021. We will present our idea about improving
Unmarking Decisioning and Positioning by using Pass Prediction Deep Neural
Network. Based on our experimental results, this idea proven to be effective on
increasing the winning rate of Cyrus against opponents.
