2/20/2022 – The Grandmasters Dr. Karsten Mueller and Luis Engel have set a ball rolling in Germany with their latest Fritztrainer. GM Lars Bo Hansen designed the four-player model in 2005, and was perhaps ahead of his time. In the 5-part interview with Dr. Karsten Mueller, all four player types are discussed in detail. Today - The Theorist.

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’.
In this course, Grandmaster Felix Blohberger delivers a complete opening repertoire for White, centred around the flexible move 1.Nf3.

The 4 Player Types standard model
by Dr. Karsten Mueller and Luis Engel
Some chess players love to attack, others prefer a solid defence. Some know all the opening theory and others play purely by intuition/recognition. But can we all agree that there is no perfect way to play chess yet?
Every type of player has their strengths and weaknesses.
Namely:
The activist (Aronian, Kasparov, Polgar, Tal)
The reflector (Carlsen, Capablanca, Karpov, Keymer)
The pragmatic (Caruana, Fischer, Euwe, Korchnoi)
The theorist (Giri, Steinitz, Botvinnik, Kramnik)
GM Karsten Müller and GM Luis Engel spent a lot of time defining the model of the four player types, wrote a book and developed the Fritztrainer, which is very popular in Germany.
In this five-part interview series with one of the authors, Dr Karsten Mueller, we take a more in-depth look at all four player types and summarize some open questions in the last part.
