Soenke Maus and his contribution to opening theory

by Johannes Fischer
6/20/2026 – At the end of the 1980s, Soenke Maus, who was born on 11 June 1967 in Bad Schwartau and celebrated his 59th birthday last week, was regarded as one of Germany's greatest talents. But in 1995 he ended his chess career and became a successful marine researcher in Norway. Maus played his most famous game in 1989 at an open tournament in Lugano: he won in just 19 moves, in a theoretically important variation, against Dr Robert Hübner. | Pictured: Soenke Maus, 1994 | Photo: Torsten Szobries

FRITZ is more than just a chess engine – it’s a training revolution! Whether you’re taking your first steps into the world of club chess, or already playing at a tournament level: with FRITZ, you can train more efficiently, intelligently and with a more personalised approach than ever before.

Innovations such as 13.O-O-O spread around the world at lightning speed today thanks to modern media, but at the time two more prominent players still fell victim to it.

Maus' win against Hübner caused a sensation in German chess circles, but it took a while for the novelty to reach the wider chess world. This sluggish flow of information brought Stefan Kindermann an easy win a week later in the fourth round of the Dortmund Grandmaster Tournament against Russian grandmaster Lev Psakhis.

A further month later, on 13 April 1989, Chandler's discovery claimed another victim - Wolfgang Uhlmann, one of the greatest French Defence experts of all time.

Nowadays, in the internet age, such successes are scarcely possible anymore. Engines already warn of possible dangers during opening preparation, and spectacular novelties have a short shelf life. But opening preparation remains important, even if one has to look for new ways to surprise one's opponents.
