A primary role is played here by the effort we have invested in studying.ampamp10In middlegame theory things are even tougher. We are obliged to study variousampamp10types of positions with specific strategic and tactical attributes so as to understandampamp10the underlying ideas and be able to employ them ourselves in similar situations.ampamp10While players have studied these topics and acquired knowledge it isampamp10the application of this knowledge in practice that helps differentiate between them.ampamp10Chess is not a simple game.ampamp10The purpose of this series is to introduce the reader to advanced training conceptsampamp10using the same methods of presentation and instruction that were taught to greatampamp10players by famous trainers that they have worked with.ampamp10The series will continue with the topic of the Bishop Pair the first volume handled bishop endings and we will examine how toampamp10handle this ampamp8220power of the sunampamp8221 coupling.
