If you don’t pass through Grand Central often, you probably don’t know that there is a state-of-the-art glass-enclosed squash court underneath the gleaming period chandeliers of Vanderbilt Hall. One guidebook calls it “a combination of the U.S. Open and an Apple store.” From January 20 to 26, the J.P. Morgan Tournament of Champions will be in full swing. You can watch free from the front wall, but people interested in the sport are advised to buy a seat for a close look at the action. Once named by Forbes magazine as one of the 10 healthiest sports in the world, squash has an international following, and the current top 50 players hail from 20 countries—right now, the Egyptians seem to have the edge. If you already play, you can register for the largest amateur singles tournament in the world, taking place January 20 to 22. Starts today, through January 26.
