In the introduction to this product, GM Bojkov writes: "With this new mini-video series I tried to bring to life my methodology of in-depth preparation and help you build the bridge yourselves. The better you understand the middlegame, the easier the transition between the chess phases will be, the quicker you will make your decisions and the better your play will become. You will never drift after the opening and will always know what to look for.".
