The glance can also help you decide on how you are going to go into second base. The main thing to realize is that the quickest way to second base is a strait line and slide that is strait into the bag. Many players learn to hook slide in addition to a strait slide, in reality the only reason to use a hook slide is to avoid being tagged when you are sure to be out if you slide strait in. If you are sure your going to be tagged out, you may find a strait slide to the back side of second base is your best chance to get in safe. This works best when the infielder covering the bag is not straddling the bag but is to the inside.
Baseball is like church, many attend, but few understand.
