'Practical Cushion System - SOCS -'is a very useful cushion system for pocket billiards. Because it is not theoretical but practical. I shoot for the cushion, over and over again!.I finally work out the system that Sugimoto's Original Cushion System = SOCS.
I dedicate this application to all who loves pocket billiards.
