Books or Videos? I might create a book but I'm more fun in videos. If you don't enjoy my videos then I'll make you an e-book but that is not the real discussion for this project, we will discuss the starting of the London System. The London System is very easy to play due to it' s short variations. You will experience many openings in the London System. If you want to play d4 but you really want e4, you an just transpose it to the London System. For example you played e4. If your opponent plays Caro-Kann, this will be very effective. With d4, Bd3, c3, and Bf4 you tansposed it to the main line of the London System.
