Hello everyone! I am new to magic and I just got The Expert at the Card Table today. I was looking through it and saw quite a bit on a technique called a shift. The issue is, I have no idea what that is... If anyone could kindly let me know what that is, I would be very appreciative. Also, if anyone knows of any other weird definitions that a beginner may not know, please feel free to post them here as well! Thank you!
