Strokes of the Game

Each chukker starts with a ball thrown in by the referee. The teams change sides every time a goal is scored. The team that scores more goals wins( RULE 18). 

Games can consist of four or six chukkers depending upon the level of polo and availability of mounts. 

Most Club polo is 4 chukkers games. Each horse can typically play upto two chukkers in Club polo games. 

Tournament games are more often six chukker games.

Each Chukker is seven minutes play time but with the clock stopping for penalties, goals scored and knock ins a chukker typically spans ten to twelve minutes.

The well appointed polo player and pony; 
“ few if any sight is as regal as a rider and horse” !

A rather aggressive ride off; an elbow nudge being executed by the player in red is a ​no no!!
Off side and near side neck shots above left and right. 
Near side back hand ( a very difficult stroke to master) below. 
Note: The near side is the left side of the horse and the far side is the right side of the horse. 

Polo is a high contact sport and bumping the opponent off with full force at a ​narrow angle is legal and an integral part of the game as it is an absolutely necessary maneuver to wrestle control of the line of the ball.
An off side forehand (bottom left)is the most often used stroke and forms well over 80% of the strokes employed by the average player in club level polo. 
The near side back hand (bottom right)is an advanced stroke and takes time to master. 

Reaching across the opponents mount with an outstretched mallet is dangerous play and thus illegal.
When two players are riding each other off 
Players #2&4)to wrestle control of the line of the ball and thus the ball itself then an opponent (approaching “enface”)has no play on that ball.

Crossing the line of the ball is the cardinal error that invites the blow of the umpire whistle as it is dangerous play(player following the red line is crossing over the green line if the ball”).
One of the most dangerous plays in polo is either to ride into the hind end of a player in front or more sinisterly cut off very close across the front of the ​opponents horse behind thus entangling the front legs of the horse behind in the rear legs of the horse that cut in front.
The High Hook though tempting is a foul.
