Horse lovers know that horses are community oriented intelligent animals. When you ride long enough the horse begins to understand the cues of the rider on a subconscious level. It is this subtle cue exchange that might enhance performance. This is even more true in polo where the horse and rider must maneuver through the smallest adjustments that determines whether someone makes or misses the next goal.
The more polo players can create this bonding the more likely they are going to find improved performance benefits that can only come from practice and horse trust. Would it improve your game?
