What subtle cues help an expert player 'read' an opponent's future movements or ability usage?

Expert players read opponents by observing a combination of subtle cues related to movement patterns, resource management, behavioral tells, current game state analysis, psychological factors, and opponent-specific knowledge. Movement patterns involve an opponent’s subtle positioning or navigation shifts. For instance, a slight alteration in their path, an unusual route choice, or a tentative step forward or backward can indicate an intention to use a specific ability or to initiate an attack. An opponent retreating slightly but not fully disengaging might be attempting to 'bait' (lure into a disadvantageous position) a chase for a counter-attack.
