Squash is a horrible game. It makes competitors hate each other, and the umpires as well. Squash is nice to play socially against friends or practice alone on a court for fitness. How do I know? After many decades, and knowing that competitors are not home friends. Many tennis players and athletes etc were frieds.
My goodness the refereeing is like a pinball machine - you never know how its going to go. Zero consistency. Plus the cameras only pick up the ball 5% of the time.
