Obviously when Ramy Ashour is involved in a rally where he has to chase the ball it's always hilarious: such is his agility, speed and most of all, his extraterrestrial interception.
But even when it's that entertaining, there are also lessons to note: when you watch the rally for the second time, observe to what extent they use the very low (just above the tin) and the higher parts of the frontwall.
Common players hit mostly the mid range of the wall, Ramy and Pilley play in average at least every second ball either just above the tin or over the service line. Good squash - or as I like to call it: beautiful squash - always requires not only to use all four corners of the court, but also the full range of the frontwall, and pretty often the extremities of it.
