With the second book of the series, we continue with the systems from where we left off. As I said in the first book, are you bored with the known diamond systems or do you have difficulty in applying them? Here are systems outside of the usual systems. Learning pool systems has never been so easy and fun. No need to memorize confusing formulas or individual points for each system. Systems that are explained in a very understandable way and that you won't find anywhere else. And finally, an organic system. Yes, don't you want to have a system of your own? Create your own system by using the systems here. Start experimenting right now. You can find extensive information about the general use of the system in the first book.
