Personally, I struggled a bit
to concentrate on the chip tricks in this video; something (or 4 things) kept me distracted.
I remember when I used to have no game at chip tricks at all. The inflection point on the rise of my game happened at Junell's bachelor party when I sat in between two guys that had magician-calibre chip tricks (something that should be a warning to leave the table!) in my marathon 20 hour session. They spent about 12 hours teaching me tricks, including my signature spin. I have been in a rut on tricks - just more deviations of "chips over the stack" and "spins". I think my new challenge will be to learn the bouncing the chip onto my stack, one that is in this video (not that I paid any attention).
