Charles Storey's "Positional Chess Skills" - Changing positional advantages

A positional advantage can be something hard to spot, especially when the player is not an expert. But, following FM Storey's lessons, at this point, you can recognize a positional advantage. This new piece of know-how makes you ready to appreciate how to change a positional advantage into a different kind of it and to convert a game into a win when you realize that changing approach to your advantage can lead to a greater one. In the first game Charlie shows us in this video, the Master of Positional Chess Ulf Andersson plays a much lower-rated player. It is quite impressive how Andersson, using his positional skills, doesn't need to calculate at all to win the game.
