Playing styles in chess are an important and thus often discussed topic. GM Dr. Karsten Müller and GM Luis Engel take up a model by GM Lars Bo Hansen based on 4 player types – namely ‘activists’, ‘pragmatics’, ‘theoreticians’ and so-called ‘reflectors’. Their respective strengths and weaknesses are explained with the help of many examples, enabling the reader to try and assign himself or herself to one or the other player type.
