Becoming an "A" squash player

Pro Nathan Dugan in Chicago (former world top 50) has the following advice for becoming an "A" player:

Keep working hard on movement drills as that needs to be second nature and when you practice your swing, practice hitting different paces of shot into the same target area. "A" players have a command of various paces of ball control at all times, even when under pressure. There is always more than 1 way to hit a ball into the same corner.
